Inbound Server Agent Port The Server Agent accepts connections on the following port.
Unisphere Features Unisphere provides the following features. Storage Center Management Unisphere 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. Related concepts Storage Center Administration on page 45 Servers Unisphere allows you to manage the storage that is allocated to servers.
2 Getting Started To manage multiple Storage Centers, open a web browser and connect to the Data Collector. To manage a single Storage Center, open a web browser and connect directly to the Storage Center. Topics: • • • Connect to Multiple Storage Centers Using Unisphere Central Connect Directly to a Storage Center Using Unisphere Next Steps Connect to Multiple Storage Centers Using Unisphere Central Start a web browser and use it to connect to the Data Collector.
Next Steps This section describes some basic tasks that you may want to perform after your first log on to Unisphere. These tasks are configuration dependent and not all tasks are required at all sites. Add Unisphere Users Depending on your configuration, you can add users to your system using the Data Collector or you can create local users on the Storage Center using Unisphere.
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: • • • Storage Center Hardware Components How Storage Virtualization Works User Interface for Storage Center Management Storage Center Hardware Components Storage Center consists of one or two controllers, switches, and might include one or more disk enclosures.
● ● ● ● Volumes – Allocate storage for use. Storage Types – Define a datapage size and redundancy levels for the disk folder. Data Progression – Moves pages between tiers and drive types, as well as among multiple RAID levels within the same tier. Storage Profiles – Define how data progression moves pages between tiers. Volumes A Storage Center volume is a logical unit of storage that can represent more logical space than is physically available on the Storage Center.
○ RAID 10 (each drive is mirrored) ○ RAID 5-5 (striped across 5 drives) ○ RAID 5-9 (striped across 9 drives) ● Dual redundant: Dual redundant is the recommended redundancy level for all tiers. It is enforced for 3 TB HDDs and higher and for 18 TB SSDs and higher.
● Creating disk folders ● Adding disks to disk folders ● Managing disk spares Disk Folders A disk folder contains both managed drives and spare disk space. Managed drives are used for data storage. Spare disk space is held in reserve to automatically replace a drive if a drive fails. By default, the Assigned disk folder is the parent disk folder for all drives. Drives are further grouped by class in subordinate folders. Disk Classes Disks are classified based on their performance characteristics.
Data Progression Storage Center uses Data Progression to move data within a virtualized storage environment. Data Progression moves data between tiers and drive types, as well as among multiple RAID levels within the same tier, for a constant balance of performance and cost. How Data Progression Works Once every 24 hours, Storage Center assesses disk use and moves data to disk space that is more efficient for the data usage.
CAUTION: Because Emergency mode prevents all server I/O, Emergency mode is service affecting. Administrators must take special care to continually monitor free space on the Storage Center and add or free up space as needed to avoid reaching the Emergency mode threshold. Troubleshoot Conservation or Emergency Mode To resolve Conservation or Emergency mode, reclaim consumed disk space. About this task Perform each step, then wait a few minutes and check available disk space. Steps 1.
Name Initial Write Tier Tier (T) and RAID Levels Progression Low Priority (Tier 3) 3 Writes: T3 RAID 10 No Snapshots: T3 RAID 5/RAID 6 NOTE: The Recommended, High Priority, and Medium Priority profiles are not available for the Flash Optimized storage type. Recommended (All Tiers) The Recommended storage profile is available only when data progression is licensed. Cost and performance are optimized when all volumes use the Recommended storage profile.
Name Initial Write Tier Tier (T) and RAID Levels Progression Write Intensive (Tier 1) 1 Writes: T1 RAID 10 snapshots: T1 RAID 10 No Flash Only with Progression (Tier 1 to Tier 2) 1 Writes: T1 RAID 10 snapshots: T2 RAID 5 Yes to Tier 2 only Low Priority with Progression (Tier 3 to Tier 2) 3 Writes: T3 RAID 10 snapshots: Yes to Tier 2 only T3 RAID 5/6 or T2 RAID 5 Low Priority (Tier 3) The Low Priority profile provides the most cost efficient storage.
● Creating disk folders ● Adding disks to disk folders ● Managing disk spares Storage Types for SCv2000 Series Storage Systems SCv2000 series controllers create a storage type for each disk class, and manage storage types automatically.
User Interface for Storage Center Management The user interface varies depending on whether you connect directly to a Storage Center or connect through a Data Collector.

Managing Virtual Volumes With Unisphere Central VVols is VMware’s storage management and integration framework, which is designed to deliver a more efficient operational model for attached storage.
VMware Virtual Volume Concepts The following figure shows the virtual volumes (VVols) model defined by VMware. The VVol framework introduces these components: ● VASA provider — A VASA provider (VP) is a software component that acts as a storage awareness service for vSphere. Storage vendors develop VASA providers to work with their specific storage arrays. ● Protocol endpoint (PE) — A protocol endpoint is the connection used for VVol storage, and the means by which you can access VVol storage containers.
● Use Unisphere Central to create datastores of type VVOL, which are mapped to the storage containers on the array using Unisphere Central ● Use vCenter to create VVol-backed VMs Unisphere Central provides Summary and Storage views that provide information about storage containers, datastores, VVols, and protocol endpoints. These objects are managed using Unisphere Central. Protocol endpoints are created automatically by Unisphere Central and cannot be modified in any way.
Register the VASA Provider You can register the VASA provider on a vCenter server, and manage it from the Servers view of Storage Center. Register the VASA provider using one of the following methods: ● When initially registering a vCenter Server in the Unisphere Central client, select the Register VASA Provider check box. ● For a vCenter Server that is already registered in the Unisphere Central client, select Edit Settings and then select the Register VASA Provider check box.
New Installation of Dell Unisphere Central If Unisphere Central is registered with a name lookup service such as DNS server or Active Directory server, Unisphere Central certificates are generated based on its FQDN. Any IP address changes do not affect certificates. If you change the FQDN, Unisphere Central must be manually restarted if it is a Windows-based installation. It is automatically rebooted for the Virtual Appliance installation.
Managing Storage Containers A storage container is a pool of storage that is used in a VMware environment that supports VVols. Once created, you can view storage container summary, volume, and growth information. To use the storage container for VVols you must register the VMware vCenter Server and register the VASA provider using the Unisphere Central for SC Series. After a storage container has been created, you can use vCenter to create a datastore and map it (mount it) to the storage container.
3. Click the name of the storage container to modify. (Edit). 4. Click The Edit Storage Container dialog box opens. 5. Modify the fields of the storage container as needed. 6. Click OK. Delete a Storage Container You can delete a storage container if it is not being used. About this task NOTE: The Delete Storage Container task fails if you try to delete a storage container while any virtual volumes are associated with it. Steps 1.
Data Eligible for Data Reduction To reduce the impact of data reduction on read and write operations, a limited amount of data is eligible for compression and deduplication. Data Reduction Input limits the type of data that is eligible for data reduction. The following options are available for Data Reduction Input: ● Inaccessible Snapshot Pages – Allows Data Reduction to process data frozen by a snapshot and made inaccessible by new data written over the original data in the snapshot.

Related tasks Creating Volumes on page 49 Modifying Volumes on page 52 Deduplication Deduplication reduces the space used by a volume by identifying and deleting duplicate pages. Deduplication requires SSD drives.
Data Savings Ratios System Data Reduction Ratio and System Data Efficiency Ratio show the data savings on the Storage Center using the available disk space-saving features. System Data Reduction Ratio – Ratio that compares the amount of space that would be used by pages that are eligible for compression and deduplication to the amount of space actually used by those pages after Storage Center applies Data Reduction.
Pause or Resume Data Reduction Pause Data Reduction on a volume to prevent deduplication and/or compression from running during data progression. Pausing Data Reduction on a volume pauses deduplication and/or compression on all view volumes created from the original volume. After pausing Data Reduction, compression and deduplication stop running on new data but the existing data is not uncompressed.
Disable Data Reduction for a Volume Disabling Data Reduction on a volume permanently uncompresses the reduced data starting the next data progression cycle. Steps 1. If you are connected to a Data Collector, select a Storage Center from the drop-down list in the left navigation pane of Unisphere Central. 2. From the STORAGE menu, click Volumes. The Volumes view is displayed. 3. In the Volumes view, select the volume you want to modify. 4. Click (Edit). The Edit Volume dialog box opens. 5.

9 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.
Topology Limitations for Volumes Associated with Multiple Replications The following limitations apply to volumes that are associated with multiple replications. ● Only one synchronous replication can be configured per source volume. Subsequent replications must be asynchronous. ● For cascade mode (replications configured in series), only the first replication can be a synchronous replication. Subsequent replications in the series must be asynchronous.

Server IO request to secondary volume (forwarded to primary Storage Center by secondary Storage Center) 7.
Automatic Swap Role for Live Volumes Live Volumes can be configured to swap primary and secondary volumes automatically when certain conditions are met to avoid situations in which the secondary volume receives more IO than the primary volume. Attributes that Control Swap Role Behavior When automatic swap role is enabled, the following limits determine when a role swap occurs.
Tiebreaker The tiebreaker is a service running on the Data Collector that prevents the primary and secondary Live Volumes from simultaneously becoming active. If the secondary Storage Center cannot communicate with the primary Storage Center, it consults the tiebreaker to determine if the primary Storage Center is down. If the primary Storage Center is down, the secondary Live Volume activates.
Figure 13. Step Four NOTE: When the primary Storage Center recovers, Storage Center prevents the Live Volume from coming online. Automatic Restore of a Live Volume Enabling Automatic Restore repairs the Live Volume relationship between the primary and secondary Live Volumes after recovering from a failure. After an automatic restore, the original secondary Live Volume remains as the primary Live Volume. The following steps occur during an automatic repair of a Live Volume.
4. The Live Volume on the primary Storage Center becomes the secondary Live Volume. Figure 15. Step Four Managed Replications for Live Volumes A managed replication allows you to replicate a primary Live Volume to a third Storage Center, protecting against data loss in the event that the site where the primary and secondary Storage Centers are located goes down. When a Live Volume swap role occurs, the managed replication follows the primary volume to the other Storage Center.

10 Storage Center DR Preparation and Activation Activate disaster recovery to restore access to your data in the event of an unplanned disruption.
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 19. 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 21. 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, Unisphere Central 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 23. DR-Activated Volume is Deactivated 1. Source volume being recovered 2. Replication over Fibre Channel or iSCSI 3.
Disaster Recovery Administration Options Use Unisphere Central to prepare for DR, activate DR, and restore failed volumes. To make sure that a site outage does not prevent you from accessing Unisphere Central to perform DR operations, you can optionally install a remote Data Collector at a DR site. A remote Data Collector provides access to Unisphere Central DR options when the primary Data Collector is unavailable.
Steps 1. Click the HOME menu. The Unisphere Central Home page is displayed. If a Storage Center is selected from the drop-down list in Unisphere Central, click (Home).

A confirmation dialog box opens. 5. Click Ok.
Defining Disaster Recovery Settings for Replications Predefining DR for a replication restore point is an optional step that configures DR activation settings for a replication restore point ahead of time, so that the DR site is ready if the destination volume needs to be activated. If you do not intend to access data from a destination site, you do not need to predefine DR settings. DR settings cannot be predefined for Live Volume restore points.
Import Activate Settings Import disaster recovery activation settings that are created on other Storage Centers or for other disaster recovery plans. Prerequisites An exported Activate Settings file must exist. The exported file is named with the file extension .emrp. Steps HOME menu. 1. Click the The Unisphere Central Home page is displayed.

Disaster Recovery Activation Limitations Activating DR for a replication removes any replications that use the activated volume (original destination/secondary volume) as the source volume. Planned vs Unplanned Disaster Recovery Activation During disaster recovery activation, you may choose whether you want to allow planned DR activation. The following table displays some of the differences between planned and unplanned DR activation.
If multiple restore points were selected to define, the Activate [ Storage Center—Storage Center] wizard advances to the next restore point. Configure the DR settings and click Next for each restore point selected. 9. Review the Activate summary and, click Finish. Restarting Failed Replications If a source volume is current and functional, and the destination system is available but a Replication failed or was deleted, you can restart the Replication.
NOTE: To restore a volume to an alternate site, consult with technical support (see https://www.dell.com/support). Volume Restore Limitations The following limitations apply to the volume restore process. ● Restoring a volume removes replications that use it as a source volume. ● Restoring an original primary Live Volume volume using a managed replication removes the associated Live Volume.
● Select the Mirror Back Only check box to skip recreating the replication in the original direction and use the DR site as the source. ● Select the Automatically Deactivate Destination check box to automatically remove server mappings from the activated volume without requiring administrator intervention. This option is available only if DR has been activated for the restore point. If this option is selected, IO to the activated volume should be halted before performing the restore. 10.
