PS Series 3000 QuickStart Step 1. Set Up the Array Hardware

D. Connect Array to a Network Switch
A PS Series array includes one or two control modules. Only one control module
is active (serving network traffic) at one time. The secondary (redundant) control
module mirrors cache data from the active control module. If the active control
module fails, the secondary will take over network operations.
Each control module has three Ethernet network interface ports, labeled PORT 0,
PORT 1, and PORT 2, for up to three active connections to the network.
In addition to the requirements and recommendations described in the following
tables, all the usual rules for proper network configuration apply to the group
members. General network configuration is beyond the scope of this document.
Network Requirements
Requirement Description
One or more
network connections
An array must have at least one functioning network interface
connected to a network (through a network switch, if possible).
When you configure the array, as described later in this
QuickStart, you assign an IP address and netmask to this interface.
In a dual control module array, to ensure network availability
regardless of which control module is active, connect a cable to
the network interface port on each control module.
Correct network
cables
Use Category 5E or Category 6 cables with RJ45 connectors. You
can also use Category 5 cables if they adhere to the TIA/EIA
TSB95 standard.
Network Recommendations
Recommendation Description
Switched Gigabit
Ethernet network
Connect arrays and hosts to a switched network and ensure that all
network connections between hosts and arrays are Gigabit
Ethernet. An array can operate at 10 and 100 Mbits, but
performance will be significantly degraded.
Multiple network
connections
For increased bandwidth and availability, connect multiple
network interfaces to the network (and different switches, if
possible). Connect interfaces in the following order: PORT 0,
PORT 1, and PORT 2.
After the initial setup, use the Group Manager GUI or CLI to
assign an IP address and netmask to each additional interface.
