Technical Guide Book for PowerVault MD3200MD3220 Product Overview The PowerVault MD3200 is the next generation series of directly connected shared SAS arrays replacing the MD3000 product in the product portfolio. The MD3200 series of arrays provides vastly superior functionality over its predecessor and is industry leading in the areas of performance, flexibility and scalability. The MD3200 series of arrays were designed with performance in mind.

The MD3200’s architecture is designed to excel in multi-host systems environments. Its I/O system core provides built-in hardware XOR for high-speed RAID parity calculations – enabling it to easily handle very compute-intensive tasks.

Technical Guide Book for PowerVault MD3200MD3220 Storage Capacity Expansion Both the MD3200 and MD3220 systems are capable of supporting up to 96 total hard drives. Adding additional drives past what the base platforms hold is a simple matter of connecting either MD1200 and/or MD1220 JBODs to the expansion ports on the MD32X0. Users can mix and match the MD1200 (3.5” HDD enclosure) and the MD1220 (2.
Technical Guide Book for PowerVault MD3200MD3220 SAS Cables The MD3200 and MD3220 arrays and the MD1200 and MD1220 JBODs standardize on the 6Gb/s (SAS 2.0) Mini-SAS cable (SFF 8088). The Mini-SAS cable is unique from the SAS cable used with the previous MD3000 array and MD1000 JBOD. Figure 13. Mini-SAS Cable Transition Connectors on both ends of the Mini-SAS cable are universally keyed. Either end of the cable can be connected to the host, MD3200 RAID controllers or JBODs.
Technical Guide Book for PowerVault MD3200MD3220 MD Storage Manager The MD Storage Manager provides the perfect combination of robustness and ease-of-use—two attributes not commonly found together in an entry-level storage management tool.
Technical Guide Book for PowerVault MD3200MD3220 Enterprise Window The Enterprise Window is the main window that opens when the MD Storage Manager is initially launched. Within the Device tab, it provides a view of all of the storage arrays, including partially managed storage arrays, in the overall management domain. It also allows for the automatic or manual addition and removal of storage and provides a view of all the MD arrays including prior generation MD3000 and MD3000i arrays Figure 14.
Technical Guide Book for PowerVault MD3200MD3220 Figure 15. MD Storage Manager: Setup Tab There are two ways to select an array to manage from the Enterprise Window. This includes; Clicking the Manage a Storage Array in the Setup tab, then select the desired storage array; or, go to the Devices tab and double-click on a storage array Either of these two options will open the Array Window for the selected storage array.
Technical Guide Book for PowerVault MD3200MD3220 Figure 16. MD Storage Manager: Array Window The Summary tab (shown above) provides administers with a quick look at all the pertinent information regarding the selected MD3200 or MD3220 storage array as well as links to various management tasks.
Technical Guide Book for PowerVault MD3200MD3220 The Hosts & Mappings area provides information about the number of hosts, virtual disk mappings, and storage partitions that have been configured. There is also a link provided to allow the user to get more detailed information about the hosts and mappings by launching a non-embedded dialog. The Information Center area provides links to various help-related information and tutorials.
Technical Guide Book for PowerVault MD3200MD3220 component, and selecting “View Associated Physical Components”. This physical view can also be retrieved by selecting the Physical tab which will be covered next. The Physical tab provides both a physical view of the storage array as well as detailed information regarding the physical components. Within the Physical tab, the Physical pane appears on the left and the Properties pane appears on the right.
Technical Guide Book for PowerVault MD3200MD3220 Next, is the Mappings tab which provides an overall view of the host-to-virtual disk mappings configured on the storage array. The Mappings window includes both a Topology pane as well as a Defined Mappings pane. Figure 19. MD Storage Manager: Mappings Tab The Topology pane shows a tree-structured view of virtual disk that are related to the storage partitions.
Technical Guide Book for PowerVault MD3200MD3220 The next tab is the Setup tab which provides access to nearly all routine administrative tasks that a user would typically run into. Figure 20. MD Storage Manager: Setup Tab The Setup tab includes tasks, such as: Blink Storage Array selection which allows the user to turn on the indicator lights of the storage array to identify it physically.
Technical Guide Book for PowerVault MD3200MD3220 It is important to note that many tasks can also be accessed from the pull down menus across the top; or, by going to the Logical, Physical or Mappings tabs in the Array Window and right-clicking on the appropriate object (i.e. storage array, virtual disk drive, controller, etc.). For example, right-clicking on an array provides the same options as clicking on the Setup tab or the top pull down menus options. Figure 21.
Technical Guide Book for PowerVault MD3200MD3220 The final tab is the Support tab which provides a central location when storage array recovery, support information or a description of the storage array components are needed. Figure 22. MD Storage Manager: Support Tab Gather Support Information selection allows a user to save information about the storage array (such as its profile and event log information) to a file so that it can be saved and sent it to technical support.
Technical Guide Book for PowerVault MD3200MD3220 Working with Physical and Logical Disks Disk Group Configuration A disk group is a set of physical disks that the controller logically groups together to provide one or more virtual disks to a host. Each disk group is comprised of the same drive technology (i.e. SAS, near-line SAS or SSD) and has an assigned RAID level. While multiple RAID levels can be intermixed in a single MD3200 series storage array, each disk group has a single RAID level.
Technical Guide Book for PowerVault MD3200MD3220 Table 7. RAID Configuration Support RAID-0 RAID-1 and 1+0 Data is striped across multiple physical disks. Physical disks operated independently with data Data is “mirrored” and parity blocks to another distributed across all physical disk. physical disks in the group. Physical disks operated independently with data and dual parity blocks are distributed across all physical disks in the group.
Technical Guide Book for PowerVault MD3200MD3220 Configuration Metadata MD3200 series of controllers store configuration metadata in a private 512 MB region on every configured physical disk. This metadata area contains physical disk state and status information, virtual disk state and status information and controller and subsystem information.
Technical Guide Book for PowerVault MD3200MD3220 application. A given host can concurrently have virtual disks with different capacities, different RAID levels, and different physical disk types. This flexibility enables hosts with different capacity, performance or data protection demands to effectively share a single storage array. Snapshot The MD3200 series of arrays Snapshot functionality provides an additional level of data protection and the means to improve production data utilization.
Technical Guide Book for PowerVault MD3200MD3220 background operation with five user-defined priority settings, enabling administrators to minimize either copy time or the overall I/O impact to the storage system. As virtual disk copy is controller based, it requires no host interaction or CPU cycles – minimizing the impact to applications and the storage infrastructure.
Technical Guide Book for PowerVault MD3200MD3220 transferred to the first controller, its flash memory is updated, and the controller is rebooted. The firmware is then passed from the first controller to the second, and the process is repeated. With a multipath driver installed, access to all storage arrays’ virtual disks is maintained throughout the process.
