Setup Guide

PS Series 3000 QuickStart Step 1. Set Up the Array Hardware
10
Access to the group
IP address
In a multi-subnet group, each configured network interface should
have access to the subnet on which the group IP address resides.
Redundant network
paths
Using a multipathing solution helps to ensure that no single point
of failure exists between hosts and arrays.
For replication, a
reliable, adequately
sized network link
For effective and predictable replication, be sure that the network
link between the primary and secondary groups is reliable and
provides sufficient bandwidth for copying data.
No STP
functionality on
switch ports that
connect end nodes
Do not use Spanning-Tree (STP) on switch ports that connect end
nodes (iSCSI initiators or storage array network interfaces).
However, if you want to use STP or RSTP (preferable to STP),
you should enable the port settings available on some switches
that let the port immediately transition into STP forwarding state
upon link up. This functionality can reduce network interruptions
that occur when devices restart, and should only be enabled on
switch ports that connect end nodes.
Note: The use of Spanning-Tree for a single-cable connection
between switches is encouraged, as is the use of trunking
for multi-cable connections between switches.
Flow Control
enabled on switches
and NICs
Enable Flow Control on each switch port and NIC that handles
iSCSI traffic. PS Series arrays will correctly respond to Flow
Control.
Unicast storm
control disabled on
switches
Disable unicast storm control on each switch that handles iSCSI
traffic, if the switch provides this feature. However, the use of
broadcast and multicast storm control is encouraged on switches.
Jumbo Frames
enabled on switches
and NICs
Enable Jumbo Frames on each switch and NIC that handles iSCSI
traffic to obtain any performance benefit and ensure consistent
behavior.
VLANs Configure switches to use VLANs in order to separate iSCSI SAN
traffic from other network traffic.
