1 Storage Manager Overview Storage Manager allows you to monitor, manage, and analyze Storage Centers, FluidFS clusters, and PS Series Groups from a centralized management console. ● The Storage Manager Data Collector stores data and alerts it gathers from Storage Centers in an external database or an embedded database. Some functions of the Data Collector are managed by the web application Unisphere Central.
Default Ports Used by Storage Manager The Storage Manager components use network connections to communicate with each other and with other network resources. The following tables list the default network ports used by the Storage Manager Data Collector, Storage Manager Client, and Storage Manager Server Agent. Many of the ports are configurable. NOTE: Some ports might not be needed for your configuration. For details, see the Purpose column in each table.
Client Ports Storage Manager clients use the following ports: Inbound Ports The Storage Manager Client and Unisphere Central do not use any inbound ports. Outbound Ports The Storage Manager Client and Unisphere Central initiate connections to the following port: Port Protocol Name Purpose 3033 TCP Web Server Port Communicating with the Storage Manager Data Collector Server Agent Ports The following tables list the ports used by the Storage Manager Server Agent.
Storage Manager Features Storage Manager provides the following features. Storage Management Features Storage Manager provides the following storage management features. Storage Center Management Storage Manager allows you to centrally manage multiple Storage Centers. For each Storage Center, you can configure volumes, snapshot profiles, and storage profiles. You can also present configured storage to servers by defining server objects and mapping volumes to them.
VVols Storage Manager supports the VMware virtual volumes (VVols) framework. VMware administrators use vCenter to create virtual machines and VVols. You must be connected to a Data Collector Managerto use VVols. When properly configured, you can use Storage Manager to manage and view VVols, storage containers, datastores, and other aspects of VMware infrastructure.
Remote Data Collector A remote Data Collector is installed at a remote site and connected to the primary Data Collector to provide access to disaster recovery options when the primary Data Collector is unavailable. In the event that the primary Data Collector is down, you can connect to the remote Data Collector at another site to perform Disaster Recovery.
Log Monitoring The Log Monitoring feature provides a centralized location to view Storage Center alerts, indications, and logs collected by the Storage Manager Data Collector and system events logged by Storage Manager. Related concepts Storage Center Monitoring on page 609 Performance Monitoring The Performance Monitoring feature provides access to summary information about the managed Storage Centers and historical/current I/O performance information.

Configuring Email Notifications for Threshold Alerts on page 583 Configure Storage Manager to Email Reports on page 594 Set up Remote Storage Centers and Relication QoS If you want to protect your data by replicating volumes from one Storage Center to another, set up connectivity between your Storage Centers. Create Replication Quality of Service (QoS) definitions on each Storage Center to control how much bandwidth is used to transmit data to remote Storage Centers.
3 Storage Center Overview Storage Center is a storage area network (SAN) that provides centralized, block-level storage that can be accessed by Fibre Channel, iSCSI, or Serial Attached SCSI (SAS). Topics: • • How Storage Virtualization Works User Interface for Storage Center Management How Storage Virtualization Works Storage Center virtualizes storage by grouping disks into pools of storage called Storage Types, which hold small chunks (pages) of data.
Switches Switches provide robust connectivity to servers, allowing for the use of multiple controllers and redundant transport paths. Cabling between controller I/O cards, switches, and servers is referred to as front-end connectivity. Enclosures Enclosures house and control drives that provide storage. Enclosures are connected directly to controller I/O cards. These connections are referred to as back-end connectivity.
○ 7K (RPM) ○ 10K (RPM) ○ 15K (RPM) ● Solid State Drives (SSDs) – SSDs are differentiated by read or write optimization. ○ Write-intensive (SLC SSD) ○ Read-intensive (MLC SSD) Drive Spares Drive spares are drives or drive space reserved by the Storage Center to compensate for a failed drive. When a drive fails, Storage Center restripes the data across the remaining drives. Distributed Sparing When updating to Storage Center version 7.3, a banner message prompts you to optimize disks.
Disk Types The type of disks present in a Storage Center determines how Data Progression moves data between tiers. Storage Center supports write-intensive SSDs, and 7K, 10K, and 15K HDDs. A minimum number of disks are required, which may be installed in the controller or in an expansion enclosure: ● An all-flash array requires a minimum of four SSDs of the same disk class, for example four write-intensive SSDs.
Table 4. SSD Redundancy Recommendations and Requirements Disk Size Level of Redundancy Recommended or Enforced Up to 18 TB Dual redundant is the recommended level NOTE: Non-redundant storage is not an option for SCv2000 Series storage systems. 18 TB and higher Dual redundant is required and enforced Data Progression Storage Center uses Data Progression to move data within a virtualized storage environment.
Emergency Mode Storage Center enters Emergency mode when the system can no longer operate because it does not have enough free space. In Emergency mode, Storage Center responds with the following actions: ● ● ● ● ● Generates an Emergency Mode alert. Expires snapshots at a faster rate than normal (Storage Center version 7.2 and earlier) Prevents new volume creation. Volumes become either inaccessible or read-only.
Storage Center Operation Modes Storage Center operates in four modes: Installation, Pre-production, Production, and Maintenance. Name Description Install Storage Center is in Install mode before completing the setup wizard for the Storage Center. Once setup is complete, Storage Center switches to Pre-Production mode. Pre-Production During Pre-production mode, Storage Center suppresses alerts sent to support so that support is not alerted to expected test scenarios caused by testing.
When a volume uses the Recommended profile, all new data is written to Tier 1 RAID level 10 storage. Data progression moves less active data to Tier 1 RAID 5/ RAID 6 or a slower tier based on how frequently the data is accessed. In this way, the most active blocks of data remain on high-performance drives, while less active blocks automatically move to lower-cost, high-capacity SAS drives.
Flash-Optimized with Progression (Tier 1 to All Tiers) The Flash Optimized with Progression storage profile provides the most efficient storage for an enclosure containing both read-intensive and write-intensive SSDs. When a storage type uses this profile, all new data is written to write-intensive Tier 1 drives. Snapshot data is moved to Tier 2, and less-active data progresses to Tier 3.
Maximize Efficiency Maximize Efficiency writes new data to RAID 5/6 and keeps snapshot data on RAID 5/6. Use Maximize Efficiency for volumes with less-important data and infrequently used data. User Interface for Storage Center Management Most storage configuration and management for an individual Storage Center is performed from the Storage view in the Storage Manager Client. Select a Storage Center in the Storage navigation pane to view and manage it.
Storage Tab The Storage tab of the Storage view allows you to view and manage storage on the Storage Center. This tab is made up of two elements: the navigation pane and the right pane. Figure 5. Storage Tab Call Out Name 1 Navigation pane 2 Right pane Navigation Pane The Storage tab navigation pane shows the following nodes: ● Storage Center: Shows a summary of current and historical storage usage on the selected Storage Center.
Right Pane The right pane shows information and configuration options for the node or object selected in the navigation pane. The information and configuration options displayed for each node is described in the online help.

7 Managing Virtual Volumes With Storage Manager VVols is VMware’s storage management and integration framework, which is designed to deliver a more efficient operational model for attached storage. This framework encapsulates the files that make up a virtual machine (VM) and natively stores them as objects on an array. The VVols architecture enables granular storage capabilities to be advertised by the underlying storage.
Use of the internal database is a consideration for lab deployments only. Depending upon the protection model used in deployment, failure to use the external database could result in the loss of some or all VVols metadata when the Data Collector is uninstalled or deleted. Use of the external database negates this risk during uninstall or delete. The external database is expected to be deployed in a highly available manner including redundant switching connectivity.
vSphere recognizes them as protocol endpoints after the VASA provider is registered and a Storage Container is created using Storage Manager. ● Storage container — A storage container is a quantity of storage made available for the placement of virtual volumes-based VMs. Each array has at least one storage container. Each storage container has one or more protocol endpoints associated with it. NOTE: Storage containers are not supported outside of the virtual volumes context.
Thick provisioning is not supported for operations such as creating or cloning a VVol VM. Only thin provisioning is supported. VASA Provider The VASA provider enables support for VMware VVols operations. A VASA provider is a software interface between the vSphere vCenter server and vendor storage arrays. Dell provides its own VASA provider that enables vCenter to work with Dell storage. This VASA provider supports the VMware VASA 2.0 API specifications.
● Changing the Storage Manager IP address Unregistering VASA will affects control plane operations on virtual volume VMs and datastores which are in use. It does not affect data transfer between an ESXi host and the respective SAN storage. Unregistering the VASA provider results in powered-off VVol VMs being shown as inaccessible and datastores as inactive. To avoid prolonged control plane down time, minimize the period where the VASA provider remains unregistered.
IP Change Action Required networking properties on the host. Then follow the Dell Storage Manager procedure for deleting existing certificates and restart the Storage Manager. After the restart, re-register the VASA Provider. FQDN changes on Windows or Virtual Appliance If certificates are already using FQDN and you want to change the FQDN, unregister VASA Provider first. Then make changes to the name lookup service or Storage Manager host (or both) for the new FQDN.
Data Reduction Options for VVols You can specify data reduction options when creating storage containers. These options are advertised (made available) to the VMware administrator during VM Storage Profile creation. When you use Storage Manager to create storage containers, you can optionally set these data reduction options: ● Deduplication Allowed ● Compression Allowed Specifying one or both of these options indicates the data reduction preferences for VMs that are then created.
NOTE: When applying a VM Storage Policy containing rules for the ScStorageProfile capability, the vCenter administrator can ignore the datastore compatibility warning Datastore does not satisfy required properties.. The VASA provider overrides the datastore's configured value and applies the user-provided value of ScStorageProfile for VVols of the VM.
Table 9. Expected Behavior for Compression and Deduplication Checkboxes on Storage Container Old Checkbox Value New Checkbox Value Expected Behavior Compression Enabled Compression Disabled Data Reduction Profile of existing volumes remains unchanged. Compliance check warns that the VM is not compliant with storage container.
Table 10. Expected Behavior Related to Migration (continued) Source Datastore Destination Datastore Expected Behavior Storage Container Compression = Supported Storage Container Compression = Not Supported Migration fails because the source VM Storage Policy is invalid on the destination.

Protocol Endpoint Monitoring You can view details about protocol endpoints that are associated with virtual volumes (VVols). Protocol endpoints are automatically created when an ESXi 6.0 server is created in Storage Manager. Storage Manager exposes protocol endpoints in the Storage view. You can use Storage Manager to view protocol endpoint details for vSphere hosts.
If the host contains VVols, the Storage view for that host includes the following details about the protocol endpoints: ● ● ● ● ● ● Device ID Connectivity status Server HBA Mapped Via LUN Used Read Only (Yes or No) Managing Virtual Volumes With Storage Manager 187

12 FluidFS Administration This chapter describes how to use Storage Manager to manage FluidFS clusters for file storage.
FS8600 Scale-Out NAS Terminology The following table defines terminology related to FS8600 scale-out NAS. Term Description Fluid File System (FluidFS) High-performance, scalable file system software installed on NAS controllers. Appliance (NAS appliance) A rack-mounted 2U chassis that contains two hot-swappable NAS controllers in an activeactive configuration in a FluidFS cluster. Cache data is mirrored between the paired NAS controllers within the NAS appliance.
Key Features of the Scale-Out NAS The following table summarizes key features of scale-out NAS. Feature Description Shared back-end infrastructure The Storage Center SAN and scale-out NAS leverage the same virtualized disk pool. File management Storage Center SAN and scale-out NAS management and reporting using Storage Manager. High-performance, scale-out NAS Support for a single namespace spanning up to four NAS appliances (eight NAS controllers).
Feature Description Antivirus scanning SMB antivirus scanning offloading using certified third-party, Internet Content Adaptation Protocol (ICAP)-enabled antivirus solutions. Monitoring Built-in performance monitoring and capacity planning. Overview of the FS8600 Hardware Scale-out NAS consists of one to six FS8600 appliances configured as a FluidFS cluster. Each NAS appliance is a rack-mounted 2U chassis that contains two hot-swappable NAS controllers in an active-active configuration.
○ Internal network ○ LAN/client network The following figure shows an overview of the scale-out FS8600 architecture. Figure 39. FS8600 Architecture Storage Center The Storage Center provides the FS8600 scale-out NAS storage capacity; the FS8600 cannot be used as a standalone NAS appliance. Storage Centers eliminate the need to have separate storage capacity for block and file storage.
(client VIPs) on the client network that allow clients to access the FluidFS cluster as a single entity. The client VIP also enables load balancing between NAS controllers, and ensures failover in the event of a NAS controller failure. If client access to the FluidFS cluster is not through a router (in other words, a flat network), define one client VIP per NAS controller. If clients access the FluidFS cluster through a router, define a client VIP for each client interface port per NAS controller.
Scenario System Status Data Integrity Comments Simultaneous dual-NAS Unavailable controller failure in single NAS appliance cluster Lose data in cache Data that has not been written to disk is lost Sequential dual‑NAS controller failure in multiple NAS appliance cluster, same NAS appliance Unavailable Unaffected Sequential failure assumes enough time is available between NAS controller failures to write all data from the cache to disk (Storage Center or nonvolatile internal storage) Simultaneous
Using the Storage Manager Client or CLI to Connect to the FluidFS Cluster As a storage administrator, you can use either the Storage Manager Client or command-line interface (CLI) to connect to and manage the FluidFS cluster.

Managing NAS Volumes A NAS volume is a subset of the NAS pool in which you create SMB shares and/or NFS exports to make storage space available to clients. NAS volumes have specific management policies controlling their space allocation, data protection, security style, and so on. You can either create one large NAS volume consuming the entire NAS pool or divide the NAS pool into multiple NAS volumes. In either case you can create, resize, or delete these NAS volumes.
Thick provisioning allows you to allocate storage space on the Storage Centers statically to a NAS volume (no other volumes can take the space). Thick provisioning is appropriate if your environment requires guaranteed space for a NAS volume. Managing NAS Volume Space FluidFS maintains file metadata in i-node objects. FluidFS i-nodes are 4 KB in size (before metadata replication) and can contain up to 3.5 KB of file data. When a new virtual volume is created, a portion of it is allocated as i-node area.

A list of all SMB shares is displayed. 2. Right-click the required SMB share (folder) and select Properties.
NOTE: Do not attempt to create an SMB share using MMC. Use MMC only to set SLPs. Automatic ACL to UNIX Word 777 Mapping When files with Windows ACLs are displayed from NFS clients, the FluidFS mapping algorithm shows a translated UNIX access mode. Perfect translation is not possible, so a heuristic is used to translate from the rich Windows ACL to the 9 bits of the UNIX word. However, when some special SIDs are used inside ACL (for example, creator-owner ACE), the mapping can be inaccurate.

It is supported only on the redirection folders (including the redirection data information) that reside inside the local volume data. ● After the NFSv4 or SMB client is redirected to the remote server and establishes the remote connection, the client continues further communication with the remote server.
Using Symbolic Links A symbolic link is a special type of file that contains a reference to another file or directory in the form of an absolute or relative path and that affects path name resolution. Symbolic links operate transparently for most operations: programs that read or write to files named by a symbolic link behave as if operating directly on the target file.

FluidFS Data Protection This section contains information about protecting FluidFS cluster data. Data protection is an important and integral part of any storage infrastructure. These tasks are performed using the Storage Manager Client.
Managing Snapshots Snapshots are read-only, point-in-time copies of NAS volume data. Storage administrators can restore a NAS volume from a snapshot if needed. In addition, clients can easily retrieve files in a snapshot, without storage administrator intervention. Snapshots use a redirect-on-write method to track NAS volume changes. That is, snapshots are based on a change set.
Managing Scheduled Snapshots You can create a schedule to generate snapshots regularly. To minimize the impact of snapshot processing on system performance, schedule snapshots during off-peak times. Snapshots created by a snapshot schedule are named using this format _YYYY_MM_DD__HH_MM Create a Snapshot Schedule for a NAS Volume Create a NAS volume snapshot schedule to take a scheduled point-in-time copy of the data. Steps 1. In the Storage view, select a FluidFS cluster. 2.
2. Click the File System tab. 3. In the File System view, expand NAS Volumes and select a NAS volume. 4. In the NAS Volume Status panel, click the Snapshots & Clones tab. 5.

Click OK. Delete a Snapshot Delete a snapshot if you no longer need the point-in-time copy of the data. Steps 1.
● The FluidFS cluster deletes any snapshots that were created after the snapshot from which you restored the NAS volume. Snapshots created before the snapshot from which you restored the NAS volume are not affected. ● Current SMB clients of the NAS volume are automatically disconnected. ● Current NFS clients of the NAS volume receive stale NFS file handle error messages. You must unmount and then remount the NFS exports. CAUTION: The restore operation cannot be undone.
Managing NDMP The FluidFS cluster supports Network Data Management Protocol (NDMP), which is an open standard protocol that facilitates backup operations for network attached storage, including FluidFS cluster NAS volumes. NDMP should be used for longer-term data protection, such as weekly backups with long retention periods.
Table 20. NDMP Agent Characteristics (continued) Functionality Supported Range Concurrent NDMP sessions Up to 10 DMA user-name length 1–63 bytes (accepts Unicode) DMA password length 1–32 characters Maximum number of include paths for an NDMP job 32 Maximum number of exclude paths for an NDMP 32 job NOTE: Your environment should allow ICMP (ping) traffic between the FluidFS controllers’ private IP addresses (not the access VIPs) and the backup server.
Table 21. Supported NDMP Environment Variables (continued) Variable Name Description Default is added to the backup stream during incremental backup so that the recovery operation can handle files and directories deleted between the incremental backups. During backup, if this variable is set, an additional directory listing is added to the backup data stream. Because of the additional process required, this addition could affect the backup data stream size and performance.
than just backing up the first instance of the hard link files. In this case, a selective restore will always have the file data. The disadvantage of this option is that backups might take longer and more space is required to back up a data set with hard link files. Backing Up NAS Volume Data Using NDMP The FluidFS cluster does not use a dedicated IP address for backup operations; any configured client network address can be used. Data is sent over Ethernet.
Environment Variable Description Used In Default Value TYPE Specifies the type of backup and restore application. The valid values are: ● dump – NDMP server generates inode-based file history ● tar – NDMP server generates file-based file history Backup and Restore dump FILESYSTEM Specifies the path to be used for the backup. The path must be a directory. Backup None LEVEL Specifies the dump level for the backup operation. The valid values are 0 to 9.
Environment Variable Description Used In Default Value Backup N to backups using the LEVEL environment variable. The valid values are: ● -1 – Specifies that token-based backup is disabled ● 0 – Specifies that a token-based backup is performed. After the backup completes, a token can be retrieved by using the DUMP_DATE environment variable. This token can then be passed in a subsequent backup as the value of BASE_DATE.

NAS Volume Configuration Backups Whenever a change in the NAS volume's configuration is made, it is automatically saved in a format that allows you to restore it later. The configuration is stored and encrypted in the .clusterConfig folder, which is located in the NAS volume's root folder. This folder can be backed up, either individually, or with the NAS volume's user data, and later restored. The configuration of a NAS volume can be restored on another NAS volume on the same system or on another system.
● The storage administrator can copy the .clusterConfig folder to a NAS volume in the system from its backup or from another system using an NDMP restore. When using a backup from another system, the restore operation works only if the saved configuration was taken from a system using the same FluidFS version. ● The .clusterConfig folder is automatically copied to target NAS volumes during replication.

Troubleshooting Common Issues This section contains probable causes of and solutions to common problems encountered when using a FluidFS cluster.
● DNS might not be configured. ● NTP might not be configured. Workaround When configuring the FluidFS cluster to connect to an Active Directory domain: 1. Ensure that you use a FQDN and not the NetBIOS name of the domain or IP address of the domain controller. 2. Ensure that the user has permissions to add systems to the domain. 3. Use the correct password. 4. Configure DNS. 5. The FluidFS cluster and Active Directory server must use a common source of time.
2. Use the password configured in Storage Manager for the NDMP client while setting up the NDMP backup/restore in your backup application. If the backup application can log into the FluidFS cluster, but no NAS volumes are available for backup, verify that the FluidFS cluster has NAS volumes created on it. Troubleshoot SMB Issues This section contains probable causes of and solutions to common SMB problems.
Workaround 1 Update to FluidFS MR640 or later. Workaround 2 Disable SMB v3 and use SMB v2: 1. Start Dell Storage Manager. 2. In the Storage view, select a FluidFS cluster. 3. Click the File System tab. 4. In the File System view, select Client Accessibility. 5. Click the Protocols tab. 6. Select Edit SMB Protocol Settings. 7. Clear the check box next to SMBv3 Protocol. 8. Click OK to save settings. SMB ACL Corruption Description SMB ACLs are corrupt.
SMB Delete On Close Denial Description Files are deleted while they are in use. Cause If multiple users are working on the same file and one user deletes the opened file, it is marked for deletion, and is deleted after it is closed. Until then, the file appears in its original location but the system denies any attempt to open it. Workaround Notify the client who tried to open the file that the file has been deleted.
Verify that you can access the problematic SMB share using a Windows client: 1. Click Run. 2. Enter the client access VIP and share name: \ \\ SMB Share Name Truncated In Event After Mapping SMB Share Description After a client maps a SMB share, the following event is generated and the SMB share name is truncated in the event. In this example, the SMB share name is share1_av. SMB client connection failure. Un-available share \ \172.22.151.106\share1_a Cause This is a
Troubleshoot NFS Issues This section contains probable causes of and solutions to common NFS problems. Cannot Mount NFS Export Description When attempting to mount an NFS export, the mount command fails due to various reasons such as: ● Permission denied. ● FluidFS cluster is not responding due to port mapper failure - RPC timed out or input/output error. ● FluidFS cluster is not responding due to program not registered. ● Access denied. ● Not a directory.
% showmount -e Export list for : /abc 10.10.10.0 /xyz 10.10.10.0 If the NFS export is available, review the NFS export name spelling in the relevant mount command on the client. It is recommended to copy and paste the NFS export name from the showmount output to the mount command. NFS File Access Denied Description This event is issued when an NFS client does not have enough permissions for the file on a NAS volume.
Cause This error is usually the outcome of a communication error between the FluidFS cluster and the NIS/LDAP server. It can be a result of a network issue, directory server overload, or a software malfunction. Workaround Repeat the below process for each configured NIS/LDAP server, each time leaving just a single NIS/LDAP used, starting with the problematic server. 1. Inspect the NIS/LDAP server logs and see whether the reason for the error is reported in the logs. 2.
NFS Write To Read-Only NAS Volume Description A client tries to modify a file on a read-only NAS volume. Cause A NAS volume is set to read-only when it is the target of a replication. The most frequent reason for this event is either: ● The client meant to access the target system for read purposes, but also tries to modify a file by mistake. ● The client accesses the wrong system due to similarity in name/IP address.
Cause It is impossible to change only the file owner ID to UID if the original file ownership is SID/GSID. Workaround To change the file ownership to UNIX style ownership, set UID and GID at same time. Problematic SMB Access From a UNIX/Linux Client Description A UNIX/Linux client is trying to mount a FluidFS cluster SMB share using SMB (using /etc/fstab or directly using smbmount).
RX and TX Pause Warning Messages Description The following warning messages might be displayed when Storage Manager reports connectivity in a Not Optimal state: Rx_pause for eth(x) on node1 is off. Tx_pause for eth(x) on node 1 is off. Cause Flow control is not enabled on the switch(es) connected to a FluidFS cluster controller. Workaround See the switch vendor's documentation to enable flow control on the switch(es).
Replication Target is Not Optimal Description Replication between the source NAS volume and the target NAS volume fails because the target NAS volume is not optimal. Cause Replication fails because the file system of the target NAS volume is not optimal. Workaround Check the system status of the target system to understand why the file system is not optimal. The replication continues automatically after the file system recovers.
Workaround Contact technical support to resolve this issue. Replication Target Does Not Have Enough Space Description Replication between the source NAS volume and target NAS volume fails because there is not enough space in the target NAS volume. Cause Replication fails because there is not enough space in the target NAS volume. Workaround Increase the space of the target NAS volume.
Troubleshoot System Issues This section contains probable causes of and solutions to common system problems. NAS System Time Is Wrong Description Scheduled tasks are running at the wrong times.

Cause ● The time on the FluidFS cluster is incorrect. ● No NTP server is defined for the FluidFS cluster. ● The NTP server servicing the FluidFS cluster is either down or has stopped providing NTP services.
Workaround If a user frequently needs to perform a cross-protocol security related activity, split the data into separate NAS volumes based on the main access protocol. Attach Operation Fails Description The operation to attach the NAS controller to the FluidFS cluster fails. Workaround ● Connect a keyboard and monitor to the NAS controller that failed the attach operation, and view the error message to determine why the attach operation failed.
13 Remote Storage Centers and Replication QoS A remote Storage Center is a Storage Center that is configured to communicate with the local Storage Center over the Fibre Channel and/or iSCSI transport protocols. Replication Quality of Service (QoS) definitions control how bandwidth is used to send replication and Live Volume data between local and remote Storage Centers.

When you are finished, click OK.
14 Storage Center Replications and Live Volumes A replication copies volume data from one Storage Center to another Storage Center to safeguard data against local or regional data threats. A Live Volume is a replicating volume that can be mapped and active on a source and destination Storage Center at the same time. To perform replications, a Remote Instant Replay (Replication) license must be applied to the source and destination Storage Centers.
Replication Types There are two replication types: asynchronous and synchronous. Asynchronous replication periodically copies snapshot data to the destination volume after a snapshot is frozen. Synchronous replication writes data to both the source and destination volumes simultaneously to make sure they are synchronized at all times. Asynchronous Replication Asynchronous replication copies snapshots from the source volume to the destination volume after they are frozen.
NOTE: When you enable replication deduplication, the Storage Center creates a secondary 'Delta' volume. This secondary volume adds to the overall volume memory usage and therefore will reduce the amount of configurable volume space that can be deployed. The additional volume memory usage affects the overall System Scalability Guidelines that are documented in the Storage Center Release Notes.
○ Replication 1: Storage Center A → Storage Center B ○ Replication 2: Storage Center A → Storage Center C ● Cascade mode: A source volume is replicated in series to multiple Storage Centers. Example: Two replications are created in series: ○ Replication 1: Storage Center A → Storage Center B ○ Replication 2: Storage Center B → Storage Center C Topology Limitations for Volumes Associated with Multiple Replications The following limitations apply to volumes that are associated with multiple replications.

Step 2: The Source Site Goes Down When the source site goes down, the data on the source volume can no longer be accessed directly. However, the data has been replicated to the destination volume. Figure 56. Replication When the Source Site Goes Down 1. Source volume (down) 2. Replication over Fibre Channel or iSCSI (down) 3. Destination volume 4. Server mapping to source volume (down) 5.
Step 4: Connectivity is Restored to the Source Site When the outage at the source site is corrected, Storage Manager Data Collector regains connectivity to the source Storage Center. The replication cannot be restarted at this time because the destination volume contains newer data than the original source volume. Figure 58. Replication After the Source Site Comes Back Online 1. Source volume 2. Replication over Fibre Channel or iSCSI (down) 3. Destination volume (activated) 4.
Step 5B: The Activated DR Volume is Deactivated After the replication from the activated DR volume to the original source volume is synchronized, Storage Manager prompts the administrator to halt IO to the secondary volume. NOTE: IO must be halted before the destination volume is deactivated because the deactivation process unmaps the volume from the server. Figure 60. DR-Activated Volume is Deactivated 1. Source volume being recovered 2. Replication over Fibre Channel or iSCSI 3.
Disaster Recovery Administration Options Use Storage Manager to prepare for DR, activate DR, and restore failed volumes.
