Servers Introduction This chapter describes how to create, manage, and monitor servers. Defining a server enables Storage Center to pass IO through the ports on that server. Once a server is created, volumes can be mapped to it. Storage Center automatically recognizes FC IO cards within the network to which is connected. iSCSI IO cards must be configured either during setup or as they are added to the network.
Servers Servers Note For information on preparing an iSCSI server that is recognized by a Storage Center system, refer to the Storage Center Setup Guide. Creating a Server Creating a server means to identify it to a Storage Center system by using the Create Server wizard. If you are using iSCSI CHAP, add remote CHAP initiators to communicate with the server. Refer to Adding a Remote CHAP Initiator on page 182. To create a server 1 In the system tree, select the servers node.
Servers 4 Click Continue. A window allowing you to name the server appears. Figure 17. Name Server Window 5 Enter a name for the server or accept the default. Enter a folder name and any notes (up to 255 characters). 6 From the drop-down menu, select an operating system (OS) for the server. Default is Windows 2008. All servers must have an OS defined. Expand operating system folders to view operating system versions. Figure 18.
Servers Figure 19. Server Name and Attributes 9 Click Create Now. On the next window, choose from the following options: • Map the server to a Volume • Map a different Server to a Volume • Create Volume • Create Server 10 Close the Create Server wizard Note For a short time after a server is created, it may appear in the system tree with an error icon while Storage Center re-evaluates its server connectivity.
Servers Server Clusters A server cluster is a collection of servers. A server that is a member of a server cluster is referred to as a cluster node. Volumes can be mapped directly to a server cluster. All volumes mapped to a server cluster are automatically mapped to all nodes in the cluster. This increases IO efficiency and, if one server fails, IO continues to other servers within the cluster. Volumes can also be mapped to only one of the nodes within the server cluster.

Volumes Introduction This chapter describes creating and managing volumes. Volumes can be created only from an assigned folder of managed disks. A volume is a logical storage repository. You can allocate more logical space to a volume than is physically available on the Storage Center. Because user access to a volume is controlled by user groups and associated volume folders and volumes, group volumes into folders based on the way you want to control user access.
Creating Volumes Creating Volumes Creating a Volume Volumes are configured through the Configure Volume Defaults window. If some Create Volume options do not appear, defaults were configured to disallow these choices. For more information about User Volume Defaults, refer to Configuring User Volume Defaults on page 272. To create a volume with the Create Volume wizard 1 From the Storage Management window, select Create > Volume. 2 The Create Volume wizard asks you to enter a volume size. Figure 48.

Make sure that Allow Advanced Mapping is enabled in your User Volume Mapping Defaults. Refer to User Volume Defaults - Mapping on page 275. Note The advanced options available differ depending upon the configuration of the server and the configuration of the Storage Center. In the Map Volume to Server Confirmation window, click Advanced.
Mapping Volumes to a Server • By default, Storage Center uses a different LUN if the specified LUN is already in use. To use the next available LUN, check Use Next Available LUN. If you do not want to use a different LUN when the specified LUN is already in use, clear the Use Next Available LUN checkbox.
Volumes Mapping Multiple Volumes to a Server or Server Cluster To create multiple volumes automatically mapped to a server, refer to Creating Multiple Volumes for a Server on page 70. To map multiple volumes to a server 1 In the system tree, select a storage folder or the Volumes node. The volumes in that folder appear in the main window. 2 Select a volume or, using the Ctrl key, select more than one volume. Figure 57. Select Volumes to Map 3 From the shortcut menu, select Map Volumes to Server.
Mapping Volumes to a Server Figure 58.

The system asks you to confirm. Figure 59. Confirm Mapping Multiple Volumes 6 Click Map Volumes Now. The volumes are mapped to a single server. An exception to this is if the server is part of a server cluster.
Volumes When creating a server cluster, Storage Center attempts to map an included volume to the same LUN on all cluster servers. If the LUN selected is not available on a particular server, the mapping is not performed and the volume is only partially connected to the cluster. Mapping a Volume to Remote System Mapping a volume to a remote system causes the volume to appear as a remote volume on the remote system. The volume can then be used as a replication target.
Mapping Volumes to a Server Removing Mapping from a Volume 1 In the system tree, select a volume. 2 From the shortcut menu, select Remove Mappings from Volume. The Remove Mappings from Volume window appears. 3 Select the mapping(s) to remove. 4 Click Continue. The mappings confirmation window is displayed. 5 Click Remove Mappings Now.

Disks Introduction This chapter describes how to view and manage disks and disk folders. Only Administrators can manage disks and disk folders. Some commands, indicated in the command description, are available only when specifically included in Administrative privileges. System Manager displays disks both physically and logically. Physically, disks are grouped by the enclosure in which they reside as shown in the Enclosures folder icon.
Viewing Tiers Viewing Tiers Disks are originally configured when a system is set up. In most systems, all disks form one pool of storage in a managed disk folder. By default, the managed disk folder is named Assigned. Disks of different classifications, such as 15K, 10K, or FATA are all part of the managed disk folder. Storage Center assigns disks of different classifications to one of three tiers. Tier 1 is the highest performance tier; Tier 3 is the most cost efficient tier.
Disks Adding Disks to a Storage Center System As data is written, you will need to add disks or enclosures to the system. The supported maximum number of enclosures attached to a Storage Center system depends on the type of enclosure. After disks are added to a system, space may not be immediately available. Make sure that you allow enough time for the system to allocate space to use for writes. Make sure you have disks available in sufficient time to incorporated them into the Storage Center as needed.
Adding Disks to a Storage Center System 4 To manage unassigned disks, select the Disks node. 5 From the shortcut menu, select Manage Unassigned Disks. The Manage Unassigned Disks wizard appears. The system displays a list of Unassigned and Foreign Managed disks, if any. Check disks to add to the folder. Use the Shift or Ctrl key to select multiple disks. Figure 89. Select Unmanaged Disks 6 Click Continue.
Disks 7 Select disks to be designated as hot spares. If a disk fails, Storage Center automatically rebuilds the data that was on the failed disk on to the spare disk. Hot spares do not count toward usable storage, but each disk spare adds to the resiliency of your system. Depending on your configuration, select one or more disks as spares. 8 Click Continue. The system indicates that the folder will be modified. Figure 91. Assigned Folder Modified 9 Click Modify Now.
Adding Disks to a Storage Center System • Rebalance Now restripes data on to all available disks within a disk folder. Rebalancing runs in the background with low priority. Depending on your system, rebalancing can take as long as several days. However, to fully use all available space, disks must be rebalanced. For more information, refer to Rebalancing RAID on page 122. You can schedule Rebalancing for off-hours.
Disks Configuring Storage When the Storage Center system was setup, the system automatically selected redundancy levels depending upon size of disks in the folder. Refer to the Storage Center 5 System Setup Guide for more information. Modify Tier Redundancy Storage Center 5 adds RAID 6 as an option for tiered storage. Modifying Tier Redundancy requires a RAID Rebalance to be completed. Do not modify tiers unless sufficient free disk space is available within the disk folder.
Configuring Storage 3 In the Modify Tier Redundancy window, click OK. 4 Repeat for all the tiers you want to modify. 5 Click OK. If any of the modified tiers contain any disks, perform a RAID Rebalance in order to complete the tier redundancy modification. Figure 94. Modify Redundancy Rebalance If the system determines that there is sufficient disk space to rebalance data across drives, a rebalance is started automatically. Refer to Rebalancing RAID on page 122.
Disks Rebalancing RAID RAID Rebalancing restripes data to optimize the use of disk space. System Manager distributes data as evenly as possible across disks in a disk folder. Operations such as adding or removing disks or modifying redundancy levels can cause data to be unevenly distributed across disks. The RAID Rebalance process redistributes data. The process also can be used to move data off disks that were moved to another disk folder.
Rebalancing RAID RAID Rebalance may be in one of the following states: • Rebalance Not Needed - RAID Rebalance is not currently running and no classes of storage report requiring rebalance. • Rebalance Needed - One or more classes of storage on the system reports requiring a rebalance. • In Progress - RAID Rebalance is currently in progress. • Final Pass In Progress - RAID Rebalance is completing its final pass. • Rebalance Complete - RAID Rebalance has been completed successfully.
Disks Scheduling RAID Rebalancing To schedule rebalancing to start at a predetermined time such as a weekend or during times of low activity: 1 From the Storage Management menu select Disk > Rebalance RAID. The RAID Rebalance window appears. 2 Click Schedule RAID Rebalance. The following window appears. Figure 96. Schedule RAID Rebalancing 3 Enter a date or click the down arrow to view a calendar. Use the up/down arrows to select a time. 4 Click Save Schedule.
Rebalancing RAID To delete a scheduled rebalance To delete a scheduled RAID Rebalance: 1 From the View menu, choose Scheduled Events. The RAID Rebalance appears as a scheduled event. 2 Select the Rebalance event. 3 From the shortcut menu, choose Delete. The system asks you to confirm. 4 Click Yes.
Disks Managing Disks A folder that contains managed disks was created when the system was set up. In the system tree, select a disk. General disk information appears. Figure 98. General Disk Information Information in this window includes: 126 • Position: listed as enclosure and position. For example, disk 01-06 resides in Enclosure 1. To view the position of this disk in an enclosure, select a disk. From the shortcut menu, select Show Disk in Enclosure.
Managing Disks • Spare: A disk that is used for redundancy. • Type: Object type is Disk. • Enclosure: Enclosures are installed and numbered starting at the bottom of a rack. • Classification: Type of disk, such as 7K, 10K, 15K, and SSD. • Status: Up or Down. • Health: Healthy or Unhealthy. • Path Alert: Either none or alert text, such as: “Disk 5 only one path to device.” • Actual Capacity, Free Space, and Manufacturer Capacity. • Vendor, Product, Revision, Vendor Spec, and Serial Number.
Disks To move a managed disk from one disk folder to another 1 In the system tree, select a disk. 2 From the shortcut menu, select Move Managed Disk. The Move Managed Disk window appears. 3 Select a folder to which you want to move the managed disks. Alternately, you can create a new folder. See Creating a Disk Folder on page 131.) 4 Click Continue. The system asks you to confirm. 5 Click Yes (Move Now). You may have to refresh the browser before the disk appears in the new folder.
Managing Disks • If the disk is not down or is carrying User Allocated Blocks, System Manager warns you that the disk cannot be removed. • If the disk has failed or has no User Allocated Blocks, System Manager asks you to confirm the deletion. 3 Click Yes. The system deletes the disk from the folder and closes the window. You can now physically remove the disk from the system. Showing Placement of a Disk in an Enclosure 1 In the system tree, select a disk.
Disks Managed Disk Folders Viewing the Assigned Disk Folder Disks were assigned to a managed disk folder when the Storage Center was set up. By convention, the managed disk folder is named Assigned.To view the assigned disk folder, in the system tree, expand Disks. System Manager groups disks into tiers by disk type, with the capacity, spare capacity, and redundancy level of each tier. Figure 99. Assigned Disk Folder This window is display only. The name of the folder appears at the top of the window.
Managed Disk Folders Disk Folder Properties Folder properties are available only for local, managed disk folders. No folder properties are available for the Unassigned or External Device folders. To view disk folder properties 1 In the system tree, select a disk folder, such as Assigned. 2 From the shortcut menu, select Properties. The Disk Folder Properties window appears. Figure 100. Disk Folder Properties • To change the folder name, enter a new folder name. Click OK.
Disks 2 Click Yes. System Manager displays unassigned disks to be added to the new folder. Only unassigned disks can be added to a disk folder. Figure 101. Create Disk Folder 3 From the list of unmanaged disks, select disks to be included in the new disk folder. Note The redundancy level of each disk tier is selected automatically based upon the size of disks in the tier. By default, dual redundancy is selected for any tier with a drive greater than 900GB in size. 4 Click Continue.
Importing from External Device without Replication License Importing from External Device without Replication License Storage Center allows you to do a thin import from a non-Storage Center disk even if Replication is not licensed. Import from External Device uses synchronous replication to import/load data from a non-Storage Center device. Previously, this was only allowed when synchronous replication was licensed.
Disks Figure 103. Name External Device 3 Enter a name. You may choose to name this disk to indicate from where the data was imported. 4 Click Classify Now. The external device appears in the system tree in an External Device Folder. Figure 104. External Device Folder Import from External Device 1 In the System Tree, open the External Device folder to view disks classified as external devices. 134 Storage Center 5.
Importing from External Device without Replication License Figure 105. Select External Disk 2 From the shortcut menu, select Import from External Device. The system warns you that you must have sufficient space on the Storage Center system to import from an external device. Note Importing data from an external device requires the Storage Center to read all blocks to the entire size of the volume. Depending on RAID selection this may consume up to two times the storage of the volume on your system.
Disks Figure 106. Select Destination Volume 3 Click Continue. A Confirmation window appears. The QoS definition (which is required with a Replication license) appears as Local. 4 Click Import Now. 5 To view the progress of the import, select the destination volume.

(Refer to Enabling VLAN Tagging on page 171.
Viewing iSCSI Cards Enabling Jumbo Frames Note Not all cards support Jumbo Frames. Enabling Jumbo Frames in the Storage Center controller can enhance network throughput and reduce use of the CPU. A Jumbo Frame is 9000 bytes compared to normal size of 1500 bytes. Throughput for large file transfers, such as large multimedia or data files, is increased by enabling larger payloads per packet. Larger payloads create more efficient throughput and require fewer packets to be sent.
Controllers Each Storage Center iSCSI I/O card can be configured with VLAN identifier (VID). When a VID is configured, Storage Center becomes an end station in the VLAN. Outbound / Inbound Ethernet Frames When VLAN tagging is enabled, all outbound Ethernet frames are tagged. When VLAN tagging is not enabled, all outbound Ethernet frames are untagged. If the card is plugged into a switch that has been configured with a VLAN, the switch inserts the VID into the untagged Ethernet frame.
Creating a Remote Storage Center Connection Creating a Remote Storage Center Connection Once a local (source) system is connected to a remote (target) system and the remote system is connected back to the local system, you can replicate volumes from an Initiator to a Target. Note Storage Center automatically detects a Storage Center system connected via FC.

Data Instant Replay Introduction Data Instant Replay is a separately licensed Storage Center application. A Replay is a point-in-time copy of one or more volumes. Once an initial Replay of a volume is taken, subsequent Replays preserve pointers to data that has changed since the previous Replay. This minimizes the amount of storage space required to preserve periodic copies of a volume.
Viewing Replay Profiles Viewing Replay Profiles Viewing a List of Replay Profiles 1 From the system tree, select Storage > Replay Profiles. A list of Replay Profiles appears. Figure 223. List of Replay Profiles The list shows: • Name: of the Replay Profile • Daily and Sample are default profiles created by the system. Profiles created by the system cannot be modified or deleted.

Remote Instant Replay Introduction An Asynchronous Remote Instant Replay copies Replays; a Synchronous Replay copies only the raw data of a volume. Storage Center presents two means of creating Remote Instant Replays: • The most efficient means is through Enterprise Manager. Enterprise Manager is a separately-licensed application that manages and monitors multiple Storage Center systems. It greatly simplifies Remote Instant Replay.
Synchronous and Asynchronous Replications Synchronous and Asynchronous Replications Synchronous Replication Synchronous replication makes sure that a write is successfully written to the remote system before returning a Successful Completion command to the server IO request. The Storage Center does not acknowledge completion of the write-back to the Server until both the write IO to the local volume and the IO sent to the remote system are complete.
Remote Instant Replay • Define a remote system to replicate to. • Replications are mapped to or from the remote system. • There is at least one volume on the remote system to replicate to, of equal or greater size than the volume you are replicating. Estimating Bandwidth Replication bandwidth cost, capacity, availability, and usability are key considerations when developing a replication plan.
Disallowing Replications Between Storage Center Systems Disallowing Replications Between Storage Center Systems By default, Storage Centers accept replications from other Storage Centers. If the systems can see each other via FC or configured iSCSI connectivity, you are allowed to define replications between them (if properly licensed). To disallow replications between systems 1 From the Storage Management menu, select Volume > Replication > Allow Replications to/from Remote Systems.
Remote Instant Replay Establishing Physical Connectivity Both the Replicating System and the Remote system must have front end port visibility for the desired Replication type. These ports may be in the form of iSCSI or FC depending on the connectivity choice. WWN visibility of the front-end ports on controllers between the Remote Connection and Replicating Systems must include both Primary and Reserved ports (from dual controller systems) to withstand failovers.
Defining a QoS Defining a QoS Before you create a Replication, create a QoS Definition to choose a link speed and the amount of bandwidth that Replications are allowed to use between the systems. To define a QoS definition 1 From the Storage Management menu, select Volume > Replication > Manage Replication QoS Definitions. The Manage Replication QoS Definitions window appears with a list of current QoS definitions. Figure 270. Manage Replication QoS Definitions 2 Click New.
Remote Instant Replay a To create a bandwidth limit schedule, click Yes. Figure 272.

A Storage Profiles Overview 382 Changing User Volume Defaults 383 Storage Profiles Created by the System 384 Creating Custom Storage Profiles 385 Managing Storage Profiles 388 Manual Storage Mode 392 381
Storage Profiles Overview Storage Profiles describe the RAID level and tiers on which data is stored. If disk space is not available within a selected tier, space in other tiers is used until space becomes available in the selected tier. All Storage Centers provide a set of standard Storage Profiles. • If Data Progression is licensed, data can be migrated between RAID levels within a tier and between tiers. The system displays the Recommended Storage Profile to migrate data between tiers.
Changing User Volume Defaults Changing User Volume Defaults By default, Storage Profiles are applied automatically and do not appear in the System Manager. To select Storage Profiles, you must first change User Volume Defaults. User Volume defaults can be changed for: • You (the current user). • Other current Administrative or Volume Manager users who are not logged in. • New users. As new users are created, volume defaults are automatically applied.
Storage Profiles Storage Profiles Created by the System If Data Progression is licensed, cost and performance are optimized when all volumes use the default Recommended Storage Profile. If Data Progression is not licensed, the default Storage Profile is High Priority, which stores data on Tier 1. When Tier 1 is full, data is then stored on the next lower available tier. Without Data Progression, you must configure volumes to use a specific tier of storage. Data will not migrate between tiers.
Creating Custom Storage Profiles Creating Custom Storage Profiles In addition to the standard Storage Profiles provided by the System Manager, you can create custom Storage Profiles. Upgraded Storage Centers provide the standard set of Storage Profiles, as well as one or more custom profiles created when existing volumes were converted to use Storage Profiles. The custom profiles created by the system can be modified; the standard profiles cannot be modified.
Storage Profiles Creating a Volume Using Storage Profiles To select a Storage Profile during volume creation or apply a Storage Profile to one or more existing volumes, the Allow Storage Profile selection must be enabled in your user volume defaults. Refer to User Volume Defaults - Advanced on page 274. To create a volume with a storage profile from the menu 1 From the Storage Management menu, select Create > Volume. The Create Volume window appears. 2 Enter the size of a volume. 3 Click Advanced.
Creating Custom Storage Profiles Applying Profiles to Existing Volumes To select a Storage Profile when creating a volume or apply a Storage Profile to one or more existing volumes, the Allow Storage Profile selection must be enabled in your user volume defaults. Refer to User Volume Defaults - Advanced on page 274. To apply a storage profile to existing volumes 1 Select a Storage Profile. 2 From the shortcut menu, select Apply to Volume(s). A list of existing volumes appears.
Storage Profiles Managing Storage Profiles 1 In the system tree, select Storage. Figure 309. Select Storage in System Tree 2 From the shortcut menu, select Manage Storage Profiles. The Manage Storage Profiles window appears, displaying Storage Profiles for this system. Figure 310.

The System Manager displays distribution usage for the volume for each disk tier and RAID selection for a volume. Every time a data progression runs, it categorizes the location of the data in a volume. Figure 312. Volume Statistics Note Because the time it takes to move data depends on the amount of data to be migrated, Data Progression can take a significant amount of time.
Storage Profiles Manual Storage Mode Note Once enabled, manual mode cannot be disabled. 1 From the Storage Management menu, select System > Setup > Enable Manual Storage Mode. A warning window appears. Figure 313. Manual Storage Mode Warning 2 To enable Manual Storage Mode, click Continue. 392 Storage Center 5.

C Enterprise Solid State Drives Overview 402 Installation and Setup 403 401
Enterprise Solid State Drives Overview Introduction Storage Center supports Enterprise Solid State Drives (ESSD) with a capacity of 146 GB. Use ESSDs for volume data that requires drastically reduced latency and/or increased IP. For maximum IO per seconds, we recommend sites install two SBOD enclosures with two ESSDs in each. That is, do not install all ESSDs in the same SBOD enclosure.
Installation and Setup Storage Tiers and Storage Profiles After installation, ESSDs are automatically assigned to Storage Tier 1 and all other available disks classes are moved down to a lower tier.
Enterprise Solid State Drives Configuring Storage Profiles Because ESSDs are automatically assigned to Storage Tier 1 after installation (see Storage Tiers and Storage Profiles on page 403), the system-provided profiles that include Storage Tier 1 allow volumes to use ESSD storage: • On Storage Centers without licensed Data Progression, the system-provided High profile includes ESSDs.

Glossary A Assigned Disks Same as Managed Disks. Physical disks that are identified by Storage Center and to which data can be written. Assigned disks use metadata to track information about volumes on the disk and other assigned disks managed by the controller. Asynchronous Replication After data has been written to the primary storage site, new writes to that site can be accepted without having to wait for the secondary (remote) storage site to also finish its writes.
C CHA Compellent Host Adapter. CHAP Challenge Handshake Authentication Protocol (CHAP) is an option for authentication of iSCSI communications. CHAP periodically verifies the identity of a peer using a 3-way handshake, initially when the link is established. After the Link Establishment phase is complete, the authenticator sends a challenge message to the peer. The peer responds with a value calculated using a one-way hash function.
Controller Provides disk aggregation (RAID), I/O routing, error detection, and data recovery. Provides the intelligence for the entire Storage Center subsystem. Every Storage Center system contains at least one. torage Center and recommend corrective actions to improve performance and availability of the system. Copy-Mirror-Migrate Storage Center feature allowing volumes to be migrated between different disk types and RAID levels.
Dual Redundancy See Redundancy Dynamic Controllers A minimum of two Storage Center clustered controllers that provide automatic failover via an internal heartbeat E Emergency Mode Refer to Emergency Mode on page 246. Enclosure The box that holds the disks. Provides disk status, temperature sensors, cooling fans, an alarm system, and a single interface to the controller. Ethernet A protocol that defines a common set of rules and signals for networks. Eth0 Ethernet port 0.
Fibre Channel A high-speed interconnect used to connect servers to Storage Center controllers and back-end disk enclosures. FC components include HBAs, hubs, switches, and cabling. The term FC also refers to a highspeed, fully duplexed serial communication protocol permitting data transfer rates of up to 10 Gigabit per second. Front End The component in the Storage Center SAN flow of data writes (server to switch to controller to disks) that initiates data writes.
Host Bus Adapter See HBA I Initiator A source Storage Center system that initiates replication. Data is copied from an initiator to a Target System. Instant Replay See Data Instant Replay. IO Input/output. The process of moving data between a computer system's main memory and an external device or interface such as a storage device, display, printer, or network connected to other computer systems.
LUN A logical unit is a conceptual division (a subunit) of a storage disk or a set of disks. Each logical unit has an address, known as the logical unit number (LUN), which allows it to be uniquely identified. M MAC Address In computer networking a Media Access Control address (MAC address) is a quasi-unique identifier attached to most network adapters (NICs).
NAT Network Address Translation (NAT) also known as network masquerading or IP-masquerading rewrites the source or destination addresses of IP packets as they pass through a router or firewall. Most systems using NAT do so in order to enable multiple hosts on a private network to access the Internet using a single public IP address. According to specifications, routers should not act in this way, but many network administrators find NAT a convenient technique and use it widely.
Port The physical connection point on servers, switches, Storage Center controller, and disk drive enclosures that is used to connect to other devices in the system. Ports on a FC network are identified by their Worldwide Port Name (WWPN); on iSCSI networks, ports are given an iSCSI name. Preallocation Pre-allocating storage physically assigns storage to the volume before its use by the server. Not allowed for volumes already having Replays. Q QoS Definition Quality of Service.
Redundancy The duplication of information or hardware equipment components to ensure that if a primary resource fails, a secondary resource can take over its function. Storage Center provides redundancy for each component so that there is no single point of failure. Single Redundancy protects against loss of data if any one disk fails. Dual Redundancy protects against data lost if any two disks fail. Remote System A Storage Center system that sends or receives Replication data.
SCSI SCSI (Small Computer Systems Interface) is a collection of ANSI standards that define IO buses primarily intended for connecting storage devices to servers. Server Servers define connectivity to the Storage Center. They allow you to associate your server name to the hardware connectivity presented by the server for easy identification.
Storage Clustering Storage Center software providing automatic controller failover through multiple controllers in an activeactive configuration. Fully mirrored, battery backup cache provides automatic restart in the event of a controller failure. Storage Interface (back end) Refers to the storage interface of the Storage Controller.
