Best Way to Cable from FAS6240 to UCS

CLOUDMINER — Tue, 17 Feb 2015 00:15:48 GMT

I need to cable from a FAS6240 to a UCS, so that I can present iSCSI LUNs. Should I connect my 6240 directly to the UCS Fabric Interconnect? The UCS Fabric Interconnect is also connected to Nexus 7000K switches. I could connect the 6240 to the 7000K, and then iSCSI traffic would flow through the 7000K and from there to the Fabric Interconnect. Which is the best option? There is no option to have a dedicated switch for iSCSI.

Thanks!

Hello,

Though direct connecting FAS to Fabric Interconnect is supported, I would recommed to connect your FAS6240 to Nexus7000 switch(since you already have Nexus 7K in place). Please have a look at the reference architecture which we did sometime back with Nexus 7K (iSCSI.

By connecting FAS to Nexus you can leverage vPC/LACP features for your iSCSI traffic and the loadbalancing is taken care automatically.

Hope this helps.

Thanks,
