DELL PowerVault MD3200i/MD3220i Technical Guide Book Product Overview The MD3200i series of storage arrays were designed with performance in mind. Each controller is equipped with four 1Gb Ethernet ports providing total aggregated bandwidth of 800MB/s of throughput for a dual controller system which is double the throughput of the MD3000i and most competitive products in the entry-level iSCSI SAN array market.
DELL PowerVault MD3200i/MD3220i Technical Guide Book Advantages of iSCSI technology include: • Expansive Reach As a routable transport with no distance limitations, IP SANs can be located almost anywhere. The reach of a SAN throughout the organization is most often limited by the distance restriction of the interface. iSCSI removes these distance limitations to limitless boundaries and extends its scope well beyond the corporate data center to remote locations as well.

DELL PowerVault MD3200i/MD3220i Technical Guide Book Hard Drives The MD3200i and MD3220i support SAS hot-pluggable HDDs (hard-disk drives) and SSD (solid-state drives). MD3200i allows for both 3.5-inch and 2.5-inch form factor drives, and the MD3220i allows for 2.5-inch form factor drives. Note that 2.5” HDD in the MD3200i requires a unique drive carrier that houses a 2.5” HDD and fits into a 3.5” HDD slot.

Rebuild aborted Storage Capacity Expansion Both the MD3200i and MD3220i 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 MD3200i series of arrays.
DELL PowerVault MD3200i/MD3220i Technical Guide Book SAS Cables The MD3200i and MD3220i 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 MD3000i 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 MD3200i RAID controllers or JBODs.
DELL PowerVault MD3200i/MD3220i Technical Guide Book 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.
DELL PowerVault MD3200i/MD3220i Technical Guide Book MD3200i Series Storage Manager Software Packages The MD3200i series Storage Manager software contains the following four packages: • Client – This package contains the graphical user interfaces (GUI) for monitoring and managing the storage arrays. It also contains an optional monitor service used to send alerts when there is a critical problem with the storage arrays.
DELL PowerVault MD3200i/MD3220i Technical Guide Book The Enterprise Window Setup tab is also accessible in the Enterprise Window. This Setup tab provides quick access to common setup tasks. For example, from the Setup tab window, a user can upgrade controller firmware, set alert notifications (email and SNMP), and perform other high-level configuration functions. Figure 15. MD Storage Manager: Setup Tab There are two ways to select an array to manage from the Enterprise Window.
DELL PowerVault MD3200i/MD3220i Technical Guide Book 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 MD3200i or MD3220i storage array as well as links to various management tasks.
DELL PowerVault MD3200i/MD3220i Technical Guide Book • 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.
DELL PowerVault MD3200i/MD3220i Technical Guide Book clicking a 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.
DELL PowerVault MD3200i/MD3220i Technical Guide Book 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. Click the plus (+) sign or the minus (-) sign adjacent to a node to expand or collapse the view. Users can right-click a node to open a pop-up menu that contains the applicable actions for that node.
DELL PowerVault MD3200i/MD3220i Technical Guide Book 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.
DELL PowerVault MD3200i/MD3220i Technical Guide Book 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 AW and right-clicking on the appropriate object (i.e. storage array, virtual disk drive, controller, etc.). For example, rightclicking on an array provides the same options as clicking on the Setup tab or the top pull down menus options. Figure 21.
DELL PowerVault MD3200i/MD3220i Technical Guide Book 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.

Each disk group is comprised of the same drive technology (i.e. SAS, near-line SAS or SSD) and has an assigned RAID level.

Description Data is striped across multiple physical disks.
DELL PowerVault MD3200i/MD3220i Technical Guide Book each physical disk stores that physical disk’s state and status, the worldwide name of its disk group, the virtual disks it contains and the definitions for those virtual disks. Storing metadata in this nonvolatile region provides the highest availability and enables easier reconfigurations and migrations.
DELL PowerVault MD3200i/MD3220i Technical Guide Book Snapshot The MD3200i series of arrays Snapshot functionality provides an additional level of data protection and the means to improve production data utilization. Snapshot enables nonproduction servers to access an up-to-date copy of production data for a variety of applications – including backup, application testing, or data mining – while the production data remains online and user-accessible.
DELL PowerVault MD3200i/MD3220i Technical Guide Book based, it requires no host interaction or CPU cycles – minimizing the impact to applications and the storage infrastructure. Virtual disk copy can be used in conjunction with virtual disk snapshot – which creates a PiT image of a virtual disk while maintaining read / write access – enabling a complete PiT clone to be created without interrupting the I/O activity of the production virtual disk.
DELL PowerVault MD3200i/MD3220i Technical Guide Book • Non-disruptive firmware upgrades Enables controller firmware upgrades to occur with no interruption to data access. The new firmware is 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 multi-path driver installed, access to all storage arrays’ virtual disks is maintained throughout the process.
