Has anyone had experience (good or bad) with VMWare GSX Server running CentOS as a VM under high load?
Here is the situation. We are planning on rolling out some new boxes to replace an existing box. Currently this box (Sun V860) is running web services, database services, mail for students, and is an instructional box for compiling code, and web scripting among other things.
We are planning on doing one of two things, either using VMWare and splitting up the services or using Solaris Zones. The box(s) has to be able to access data stored on the SAN (Fiber Channel HBA's). The boxes(VM's), or Zones would be split up accordingly:
Database box: Oracle, Postgres, and MySQL Mail: Sendmail, POPS, and IMAPS (roughly 25,000 mailboxes) Web: Apache, PHP, mod_ssl Interactive Logins: Compilers and such.
Any information about any experiences with VMWare and CentOS, under similar load would be helpful. I will probably make this same post on the Sun Solaris Mailing List, and VMWare's forums. Thanks in advance!
