What is vmotion metro

For any larger latency, you will have to worry about a lot more than latency. So it is worthless to have vMotion support for 50ms without the supporting technologies to be able to make that experience worth while. Anyway, we have done our homework on this at VMware : …. NY to NJ, etc. For such customers they would like to treat the two sites as one logical site and be elastic between them.

They purchase special storage that can span the two sites and also special network hw to be able to stretch their L2 network across. Along with dedicated bandwidth and all. The prefer a single site for disaster avoidance. Is this part of Ent Plus only? Steve how about some professional courtesy to Duncan who has written books and provides a great deal of good info to the rest of us.

Just so you know that in vSphere 4. Things filter down as versions progress which is great and you have to remember things cost money. Yes it would be nice but if you want them pay for them. I completely agree with Oliver on this one, Steve I think most of us are here because we have a certain respect and admiration to the level of work Duncan has been doing all these years.

Skip to primary navigation Skip to main content Skip to primary sidebar I received a question last week about higher latency thresholds for vMotion… A rumor was floating around that vMotion would support RTT latency up to 10 miliseconds instead of 5. Is that cool or what? Share it: Tweet. Comments Maybe a stupid question: Is there any technical reason why the latency could not be over 10ms.

No it could easily be higher, this is probably what has been tested today. Duncan, is there a date when VI5 will be available for download? Why in hell would you want to vmotion accros physical site? BTW, cool feature! Duncan great work mate. Steve keep your emotion in check because nobody likes a smart ass or an asshole. Also a message to Steve, See Olivers comment, he was spot on.

Because of the work that Duncan does, Yellow Bricks is always my first port of call. This new workflow will allow you to change compute, network, storage and management … simultaneously! The process will even maintain virtual machine historical data events, alarms, performance counters, etc. Routed vMotion is of course not the real name of this ability, but clear enough to be understood. Until now, Layer 2 adjacency was required for vMotion. Note: subtlety lies in the fact that vMotion over Layer 3 worked but was not supported by VMware.

So, routed vMotion? Yes, it works. In vSphere 4. Metro vMotion was introduced in vSphere 5. In vSphere 6, long-distance vMotion will be possible with up to ms RTT between two hosts, allowing cross-continental migrations.
