Thanks for all the information!

 

I guess I should've been a little more clear. We already have our
installation split up into a couple servers.

1.	Apache in front of a 6GB Tomcat on a Physical machine
2.	Our MySQL db is on a separate machine that was virtualized about
6 months ago
3.	And LDAP has it's own physical machine

Virtualizing MySQL gave us some performance issues for the first month
or so, but we've finally found the right mix of settings and it's not an
issue anymore.

 

We only have the one application server though and that is what we are
trying to virtualize. It sounds like enough people are doing this
without too many problems so I think we'll go for it. I'm hoping once
we're virtualized I can get extra VMs so we can have a couple smaller
tomcats instead of one 6GB tomcat.

Hi all,

I have been getting asked by our systems team to move our Sakai app
server to a VM. Has anybody else has done this and is the performance
good enough for production?

We are currently running only one app server on real hardware with a
heap size of 6GB. We are using VMware vSphere 4, and the OS of the VM
would be CentOS 5.

Any insight is much appreciated. The only info I found about this
relating to Sakai was in this thread:

Hi Bryan,

We use VMware for everything except NFS and Database (Oracle). Our 10
application nodes (6gb heaps, RHEL x86_64) and 4 web frontends work
great under vSphere 4 with the latest tools.

Have you looked at the production deployments JIRA tickets? You'll
probably find a lot more detail there:

Cheers,
