I look forward to learning more as being relatively new I now see the value of being involved in this community. It has been a lot of fun. I just thought it would be a good idea to post the link from the forums here. It also seems that Vmware may be trying to put together a KB regarding this?

I have never seen vMotion have any issues w/ being deprioritized - even upon network saturation. It will just slow down the vMotion - but it runs on TCP (syn/ack) as well as has its own checks and balances. In addition - I have talked w/ many @ VMworld in prepping for my presentation regarding this prioritization and no Don Mannhttp://www.eplus.comnoreply@blogger.comtag:blogger.com,1999:blog-1841626496323335774.post-75265932363565003422010-09-13T14:33:07.408-04:002010-09-13T14:33:07.408-04:00Hey Andy - Great questions!

I'm throwing out what i know (which may not be much) and hoping others fill in the gap. Just trying to bring some issues to light.

I have actually discussed this with several people before, but that was on ESX4.0. <br /><br />How about the other things that you may want to rate limit? <br /><br />Thanks,<br />AndySAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1841626496323335774.post-88324810307975054102010-09-13T14:20:20.510-04:002010-09-13T14:20:20.510-04:00Brad - You are correct, I'm trying to keep thi...Brad - You are correct, I'm trying to keep this series as vendor neutral as possible and instead focus on the differences between vSS, vDS, and 1kv. But, I am thinking more and more to also add a Cisco UCS specific section highlighting the things you mentioned. I haven't written parts 2 and 3 yet, we'll see.

One advantage is that you can also employ QoS with the standard vSwitch or vDS. I know you are aware of these capabilities (you and I have discussed them), but perhaps you wanted to keep this initial discussion as vendor neutral as possible, which is understandable, and frankly, its a goodBrad Hedlundhttp://bradhedlund.comnoreply@blogger.comtag:blogger.com,1999:blog-1841626496323335774.post-6684528067239672252010-09-13T08:26:02.633-04:002010-09-13T08:26:02.633-04:00I couldn't agree more - perfect summary Ken!I couldn't agree more - perfect summary Ken!Aaron Delphttps://www.blogger.com/profile/04330656671495950454noreply@blogger.comtag:blogger.com,1999:blog-1841626496323335774.post-44626145324676724032010-09-13T08:17:58.604-04:002010-09-13T08:17:58.604-04:00Good post Aaron.

The nature of vMotion is that while you want it to be fast, it's also somewhat low priority, so QoS rather than throttling seems to make more sense. Let the traffic have the bandwidth when it's available, but slow it down if it's needed by more important traffic.ken...https://www.blogger.com/profile/16470170865342149565noreply@blogger.com
