Connecting Network Cables
A PS3000 Series array must have at least one and can have up to three active
network connections at one time. Multiple network connections are recommended
for performance and availability.
Connect cables to network interfaces as follows:
• For copper-based networks, use Category 5E or Category 6 cables with RJ45
connectors. Use Category 5 cables if they meet the TIA/EIA TSB95 standard.
• Connect interfaces in this order: Ethernet 0, Ethernet 1, and Ethernet 2.
• Connect interfaces to different network switches.
• In a dual control module array, to ensure connectivity if a control module
fails, connect a cable to the interface port on each control module. For
example, connect a cable to Ethernet 0 on CM0 and Ethernet 0 on CM1.
See the PS Series QuickStart and the Technical Report on the EqualLogic
Customer Support website for network requirements and recommendations.
For a single control module array, the minimum network configuration is one
network connection to Ethernet 0. However, the single network connection is a
potential point of failure. Therefore, it is recommended that you connect multiple
network interfaces to different network switches.
For example, if you connect cables as shown in Figure 3-4, and Ethernet 0 fails,
initiators can be redirected to another functioning interface. This configuration
provides the maximum network bandwidth.
