We currently deployed HP Intergrity blade servers, They offer great versitility, redundancy, and a rapid method of deploying multible virtual guest within 10 minutes. The blade server packaging offers the ability to add addtional blades without downtime. The integrated networking, power, and san storage reduces the need to run new cabling just to add a new server when addtional blades are added.
Room for Improvement:
I would like to see a GUI interface to mange resources and deploy new servers. The current method requires a lot of hands on with a lot of check and recheck. SAN storage lun assignment is lost on the guest side without running commands on the master server and the guest to extrapolate which physical luns are assigned to which file system.
