4.4.2.3 Configuring Microsoft Windows MPIO

Configure Microsoft Windows MPIO with the following initial configuration settings. Customized

settings may be required depending on the supported application(s).

• Change the “Subnets included” field to include ONLY the subnet(s) dedicated to the SAN

network infrastructure.

• Change the “Subnets excluded” field to include all other subnets.

• The “Load balancing policy” should remain set to the default value of “Least queue depth”.

• “Max Sessions per volume slice” should be set to the number of network ports dedicated to

SAN subnet (maximum of 4).

• “Max sessions per entire volume” should be set to three (3) times the value of “Max sessions

per volume slice” (maximum of 12).

• “Use MPIO for snapshots” should remain at the default setting.

• “Use IPv6 or IPv4” should be set to IPv4 unless your network is configured to use IPv6 as the

default communications protocol.

4.4.2.4 Configuring VMware vSphere 4.1 Multipathing Extension Module (MEM)

Configure the vSphere MEM with the following initial configuration settings. Customized settings may

be required depending on the supported application(s).

• Change the “Subnets included” field to include ONLY the subnet(s) dedicated to the SAN

network infrastructure.

• “membersessions” should be set to the number of network ports dedicated to SAN subnet

(maximum of 4).

• “volumesessions” should be left at the default value of 6.

• “totalsessions” should be left at the default value of 512.

4.5 EqualLogic iSCSI SAN Design

This section will combine all of the SAN components and information provided so far to present a

redundant EqualLogic PS Series SAN design. We also include a series of examples illustrating partially

redundant and non-redundant SAN configurations.

Note: For FS Series NAS design, the only SAN design patterns presented in this section that we

recommend in support of the NAS Service are the fully redundant and fully cabled examples

shown in Section 4.5.1. Fully cabled and redundant connection diagrams for the FS7500 are

shown in shown in Section 7.1.

The information provided here does not address all of the possible variations in a customer network

environment. All information is presented using a set of basic reference designs that make the

following assumptions:

• The SAN network is physically isolated from all other network traffic

• The examples are based on best practice design principles.

• Unless otherwise stated, all reference designs will provide end-to-end host to volume

redundant paths
