Unexpected conectivity outages at VC performance Tab

Hi Dears

This is an extract that the case 1518498961 that I've posted yesterday, I'd really apreciate all your help trying to figure out what is happening with my

infrastructure (Virtual Center 2.5.0 Build 119598) 4 hosts ESX 3.5.0, 64607 clustered base.

Thanks in advance

I have a strange behaviour with our ESX 3.5 servers, all the VMs located on those hosts, specially Database Servers (SQL2005 & Oracle10g) are presenting frequent disconnections during the day. We had to reset windows services to re-establish communication with clients. When it happens at the performance tab in VC you can see several disruptions not only in network but also in CPU, Memory, Disk, etc. I've attached all logs for your revision as well as a screenshot of performance graph.

Please take a look of the screenshot attached.

I'd show this chart to your tech support engineer. He may need to engage one of the networking specialists.

Is your vCenter server virtualized?

Thanks for reply

No, it's not. VC is a HP Proliant DL380.

In our environment there are hosted VMs with differents roles, Databases, File Servers, applications, etc.

Every time the outages happen the users suffer disconnections from virtual servers, this occur al least 3 times per day.

I've already posted the case, with all logs and screenshots, but Still I do not get useful information of the engineers.

I think that issue could be related with a bottleneck, but I need vmware check my environment to have a second opinion.

If you have any suggestion, is welcome

Tks

I've seen breaks in the performance tab before but it ended up being the result of the Virtual Center service restarting itself. Clearly that's not the issue here as your breaks seem to corospond with a loss of network connectivity. Is there any common area between all of the host that could be causing this, like maybe they all feed into a core switch that may be having some issues?
