Cisco Nexus 5548UP connecting to HP P4330 StoreVirtual over iScsi

[tlea]

Hi,

I need some advice when it comes to how to setup a port-channel between Nexus 5548UP and a HP StoreVirtual 4330 device. The idea is to use 2 10 GB ports in a port-channel group and this far I've this on the port-channel group;

interface port-channel1002

  priority-flow-control mode off

  switchport access vlan 400

  load-interval counter 2 30

  load-interval counter 3 300

What about priority-flow-control, any needs to change anything here? Any other things that needs to be considered when using iScsi?

Much appreciated!

Hi Tony,

You do not have to worry about PFC. Priority-Flow-Control is something which is related to FCOE or DCBX protocol. With iSCSI as this is a TCP traffic, you have to make sure that you have a proper QOS for the IP Subnet or VLAN that has your iSCSI hosts transmitting the data. As iSCSI rides over TCP this is the major issue that I have seen related to the valid QOS config for the traffic. There is not best practice for it but you have make sure that you added it to a class other than BE or Scavanger class.

Hope this helps.

Cheers,
