PS6010 Hardware Maintenance

Maintaining Control Modules

3–15

Connecting Network Cables

The Type 10 control module can support either copper or optical 10GE cables and 
modules using the SFP+ interface. Modules and cables are sold separately from 
the PS Series array. See Table 2-3 for supported network cable types.

Each control module has two 10GE network interface ports, labeled Ethernet 0 
and Ethernet 1. These ports require connector modules that use the SFP+ 
interface. The control modules also include one 10Mb/100Mb port labeled 
Management. The management port cannot carry iSCSI traffic. Use the 
management port only if you configure a management network. See the 

Group 

Administration

 manual for more information.

No STP functionality 
on switch ports that 
connect end nodes

If possible, do not use Spanning-Tree Protocol (STP) on switch 
ports that connect end nodes (iSCSI initiators or array network 
interfaces). 

However, if you must 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 it should only be enabled on 
switch ports that connect end nodes. 

You can use Spanning-Tree for a single-cable connection between 
switches, and you can use 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

Enable Jumbo Frames on each switch and each NIC that handles 
iSCSI traffic. 

VLANs

Configure switches to use VLANs to separate iSCSI SAN traffic 
from other network traffic.
