    MD Storage Manager included on the PowerVault MD Series resource media can be used to manage both the PowerVault MD3660i Series and other PowerVault MD Series storage arrays. MD Storage Manager is compatible with both Microsoft Windows and Linux operating systems.
  • Page 8 Different RAID levels offer different levels of accessibility, redundancy, and capacity. You can set a specified RAID level for each disk group and virtual disk on your storage array. For more information about using RAID and managing data in your storage solution, see the Administrator's Guide at support.dell.com/manuals.

    Each PowerVault MD3660i Series storage array can be expanded to a maximum of 120 (or 180, if enabled using Premium Feature activation) physical disks through a maximum of seven PowerVault MD3060e Series expansion enclosures.

  • Page 10: Redundant And Non-Redundant Configurations

    Redundant And Non-Redundant Configurations Non-redundant configurations are configurations that provide only a single data path from a host to the storage array. This type of configuration is only recommended for non-critical data storage. Path failure from a failed or removed cable, a failed HBA, or a failed or removed RAID controller module results in loss of host access to storage on the storage array.
  • Page 11 Figure 1. Four Hosts in a Dual-Controller Configuration In the following figure, up to two servers are directly attached to the RAID controller modules. If the host server has a second Ethernet connection to the array, it can be attached to the iSCSI ports on the array's second controller. This configuration provides improved availability by allowing two separate physical paths for each host, which ensures full redundancy if one of the paths fail.
  • Page 12 Figure 2. Two Hosts Connected to Two Controllers In the following figure, up to two cluster nodes are directly attached to two RAID controller modules. Since each cluster node has redundant paths, loss of a single path still allows access to the storage array through the alternate path.

    Gbps Ethernet switches. An iSCSI configuration that uses Ethernet switches is frequently referred to as an IP SAN. By using an IP SAN, the PowerVault MD3660i series storage array can support up to 64 hosts simultaneously. This configuration supports either single or dual path data configurations and either single or dual controller modules.
  • Page 15 Figure 4. 64 Servers Connected to Two Controllers The following figure shows up to 64 stand-alone servers attached (using multiple sessions) to a dual RAID controller configuration through a network using a 1 Gbps to 10 Gbps aggregation scheme. The NICs on the servers are 1 Gbps NICs and the uplink ports on the 1 Gbps switches are 10 Gbps.

However, single switch configuration is also supported. Figure 5. 64 Servers Connected to Two RAID Controllers...

    CAUTION: If a PowerVault MD3060e Series expansion enclosure that was previously attached to PERC H800 adapter is used as an expansion enclosure to a PowerVault MD3660i Series storage array, the physical disks of the expansion enclosure are reinitialized and data is lost. You must backup all data on the expansion enclosure before attempting the expansion.

    Post Installation Tasks Before using the storage array for the first time, complete a number of initial configuration tasks in the order shown. These tasks are performed using the MD Storage Manager. NOTE: If Dynamic Host Configuration Protocol (DHCP) is not used, initial configuration using the management station must be performed on the same physical subnet as the storage array.

  • Page 38: Mutual Chap

    Mutual CHAP In addition to setting up target CHAP, you can set up mutual CHAP in which both the storage array and the iSCSI initiator authenticate each other. To set up mutual CHAP, configure the iSCSI initiator with a CHAP secret that the storage array must send to the host sever in order to establish a connection.

  • Page 39: Configuring Mutual Chap Authentication On The Storage Array

    CHAP Setting Description CHAP If CHAP is selected and None is deselected, the storage array requires CHAP authentication before allowing access. To configure a CHAP secret, select CHAP and select CHAP Secret. Enter the Target CHAP Secret (or Generate Random Secret). Confirm it in Confirm Target CHAP Secret and click OK. Although the storage array allows sizes from 12 to 57 characters, many initiators only support CHAP secret sizes up to 16 characters (128-bit).

  • Page 42: Step 7: Connect To The Target Storage Array From The Host Server

    NOTE: To enable the higher throughput of multipathing I/O, the host server must connect to both iSCSI ports on each controller, ideally from separate host-side NICs. Repeat step 3 through step 7 for each iSCSI port on each controller. If using a duplex PowerVault MD3660i configuration, then LUNs must also be balanced between the controllers.
