vNIC/vHBA Placement in UCS 1.4.2b

[davidcheung]

hi all,

I found the configuration option for vNIC/vHBA Placement is changed. In 1.4.1, there is only 2 

vCons shows up for B440M1 blade. But now, when i upgraded UCS to 1.4.2b, there are 4 vCons show up for same blades.

Anybody can provide detail explaination about this change? Thank you very much!

David,

The vCon limit doesn't change based on a platform, it's a general service profile option.

As of 1.4 we integrated our C-series rack servers into UCS.  We increased the vCon count to four to support up to four adapters in rack servers.

Robert

Thank u very much.

I have 2 UCS system. One is running on 1.4(1j) and the other is running on 1.4(2b).

I can see 2 vCons in 1.4(1j) for B440M1 and 4 vCons in 1.4(2b).

Before, i put the vnic and vhba into both vcon1 and vcon2 in 1.4(1j) for HA. but now i am not sure that if i need to put vhba and vnics to all 4 vCons or not in UCS 1.4(2b)?

or just put into vCon1 and vCon2.

your help is highly appreciated.

David,

My mistake.  This was introduced in 1.4(2).

If you're using any blade, the only two connections you need to worry about are vCon 1 & 2.  vCon 3 & 4 would only apply to rack servers.

Hi Robert,

Thank you very much!

could you please advise when cisco configuration guide will be released for the new UCS release 1.4.2b?

Best Regards,

We normally only release new documentation for major release.  1.4(2b) is a minor release.

The vCon increase is one of the few noticiable changes in this release.  Normally minor updates are just patches.

I've put a request into our docs team to see if there are any updates planned.

Regards,

Here we meet again.

I read that UCSM 1.4(2b) is a recommended version. Is there any other reasonable and stable UCSM 1.4 version which I do not have to consider upgrading to 1.4(2b).

Thanks.

1.4(2b) is the most stable build.  As this build was a minor patch release, there are bugs fixed in the 1.4(1b) release.  I'd suggest going with the latest.
