PS6000 Hardware Maintenance
To display the firmware version running on an array, examine the GUI Member
Controllers window or use the CLI
command. If the firmware on a micro SD card does not match the firmware
running on an array, do not install it. Instead, contact your array support provider.
Network Configuration Recommendations
Dell recommends that you follow the guidelines in the table shown next. In
addition, all the usual rules for proper network configuration apply to group
members. General network configuration is beyond the scope of this manual.

Description
Connect arrays and hosts to a switched network and make sure
that all network connections between hosts and arrays are
Gigabit Ethernet. Although an array can operate at 10 or 100
Mbits, performance will be slower than when using a Gigabit
Ethernet switch.
For increased bandwidth and availability, connect all the
network interfaces on both control modules to multiple network
switches.
The switches must be connected using interswitch links. The
links must have sufficient bandwidth to handle the iSCSI
traffic.
After connecting the network interfaces, use the Group
Manager GUI or CLI to assign an IP address and netmask to
each interface.
In a multi-subnet group, each configured network interface
should have access to the subnet on which the group IP address
resides.
Using a multipathing solution helps to make sure that no single
point of failure exists between computers and arrays.
For effective and predictable replication, make sure that the
network link between the primary and secondary groups is
reliable and provides sufficient bandwidth for copying data.
