regarding the VSAN

[mabuhantash]

when creating VSAN and provide it to uplink in UCS , does the VSAN needs to  have the same ID on the production Vsan in the MDS- core fabric switch

I have one two Fabric each sinngle MDS- switch and I need to connectone uplinks from one single fabric interconnect a to each fabric ??

You can use one VSAN if you wish, but general practive to for separate VSAN fabrics.

If you only have 1 MDS switch you can either:

1. Create one giant VSAN on UCSM, all FC uplinks would belong to the same VSAN.

2. Create two different VSANs on UCSM, and then create two upstream VSANs on the single MDS.

If you have two MDS switches normal practice is to connect each MDS to one of the Fabric Interconnects - maintaining fabric separation.

Each port assigned to a VSAN on UCSM, but have the upstream MDS port added to the same exact VSAN.

Currently UCS does not support VSAN trunking.

I have two MDS switches for production, and I have only one single fabric interconnect A , I make two FC uplinks , one to each MDS swich.

from what I am  understanding , I  need to make the VSAN memship on the Port @ MDS connected to FC Uplink in UCs 6120 same ???

either by creating the VSAN @ USDM same with the exixiting Vsan of the MDS port.. and put the VHBA on the each servers on the same Pin goup that contain the Vsan information.

You will want to configure it like this:

1. Cable 1 or more FC connections from your 6120 to each MDS switch.
2. On the MDS make sure NPIV is enabled, "show feature" or "show run | inc npiv" to check and to enable it run "feature npiv" or "npiv enable" the command you run will depend on if you are running SanOS or NX-OS on the MDS.
3. Make the port on the MDS a member of whatever VSAN is on the switch.
4. In UCSM create 2 VSANs both under Fabric A. These will be the same VSANs you have confiigured on the MDS side.
5. In UCSM on Fabric Interconnect A drill down under Expansion Module, FC port and for each FC port that is connected select it and then change the VSAN to whatever VSAN that port is connected to.
6. Create 2 vHBA templates and set the correct VSAN on each.

Thanks for the reply it is really so help full and I make VHBA with expert profile and assign it to server.
