http://puck.nether.net/pipermail/cisco-voip/2012-October/029907.html http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements#Supported_Versions.2C_Patches_and_Updates_of_VMware_vSphere_ESXi The latter being definitive for me, they keep that doc updated pretty well and note, it states 4.1, not any other version of esxi. Martin has another issue. :) On Mon, Nov 17, 2014 at 4:46 PM, Ryan Huff <ryanh...@outlook.com> wrote: > While that particular DocWiki does suggest that it is no longer needed to > disable Large Receive Offset on ESXi 4.1 with CUCUM 8.6 and above; you > should also note that one of the specific issues having LRO on can cause is > consistent CPU pegging for the UCOS guests (wouldn't be the first time > something didn't work the way Cisco's docs say it should). > > Please also review: > https://supportforums.cisco.com/document/95886/disable-lro-ucs-uc-application-deployments > Again, I can't say beyond a shadow of doubt that this is the issue anymore > than anyone can say that it isn't. > > I would also look into the RAID drivers as well as all the physical > connections on the UCS boxes. > > Thanks, > > rh > ------------------------------ > From: wo...@justfamily.org > Date: Mon, 17 Nov 2014 14:30:21 -0700 > Subject: Re: [cisco-voip] VMware 5.5 > To: ryanh...@outlook.com > CC: m...@bilobit.com; james.buchan...@gmail.com; cisco-voip@puck.nether.net > > That page specifically says you don't have to disable LRO if you are above > 4.1 esxi with8.6 CUCM. > > Martin, which version of 5.5 are you on?
