Planning The Ip San Installation With The Dell Powervault Md3200I And Md3220I Storage Arrays; Ip San Considerations - Dell PowerVault MD3200 Series White Paper

Planning for Hyper-V: PowerVault™ MD3200 and MD3200i Series of Arrays
Power
Connect the power supplies for the Dell PowerVault MD3200 storage array to separate power sources.
Doing so ensures that even if one component fails due to a power issue, the alternative path continues
to work.
Planning the IP SAN Installation with the Dell
PowerVault™ MD3200i and MD3220i Storage Arrays
You can implement an IP storage area network (SAN) in various ways based on business requirements,
available resources, and intended application. For instance, one important but easily overlooked item
that can improve the manageability of your IP SAN implementation is to assign a consistent and
representative naming scheme to the storage arrays. This assignment is especially useful if the SAN has
more than one storage array attached to it. You can use the "blink array" feature of the Modular Disk
Storage Manager to correctly identify each storage array physically.
This section contains some general implementation guidelines; however, these guidelines might not
benefit all applications.

IP SAN Considerations

Redundancy
Redundancy requires having a second set of hardware and communication paths so that if one piece of
hardware on one path breaks down, a second path can be used. In an IP SAN, a second controller in the
storage array can perform redundancy, and redundancy is available when you use two different
switches for the iSCSI network. Figure 2 shows such a configuration.
