Planning for Hyper-V: PowerVault™ MD3200 and MD3200i Series of Arrays

Dell PowerVault MD3200i Storage Array (IP SAN)

Figure 2.

Physical Network Infrastructure

A fully redundant IP SAN is characterized by multiple physical independent iSCSI data paths between

the servers and the storage array. Make sure that each data path is on a separate subnet.

iSCSI Sessions

In the case of an iSCSI target, such as the Dell PowerVault MD3200i storage array, establish multiple

sessions to the storage subsystem from each server. Set up one session per port from each of the

network cards to each RAID controller module. This method allows one session to restart if a link goes

down and does not affect any of the other links.

RAID Level

Choose an appropriate RAID level based on your applications. RAID 1 or higher RAID levels provide some

level of redundancy that is useful in the case of failed physical disks. Each RAID level works best with

certain applications, so consider the RAID level when you configure the Dell PowerVault MD3200i

storage array.

Power

Connect the MD3200i power supplies to separate power sources. These connections ensure that if one

component fails due to a power issue, the alternative path continues to work.

Security

To secure data across an IP SAN, implement a physically independent network for the iSCSI data traffic,

and isolate it from other Ethernet traffic. Having an isolated network dedicated to storage traffic
