Storage Performance Question for Virtual Server versus Physical Server
Posted on 2007-08-07
Basically I am evaluating some options on the deployment of a mail server which is not a high load system by any means at the current time but may grow significantly over the next year. Therefore I am trying to determine the best way to minimize deployments costs while leaving plenty of options for future expansion. My question for this topic is coming from a pure data read/write performance perspective.
Basically, I'm curious if there would be any difference in performance if the server is run as Microsoft Virtual Server with a "data" VHD residing on a RAID10 volume on our SAN compared to using the Microsoft ISCSI Initiator "inside" the Virtual Server to directly connect the Virtual Server to a RAID10 SAN Volume.
Lastly, how would the performance from strictly a read/write data performance perspective (ie I know there is going to be cpu overhead from running on VS) compared to running the server as a physical machine attached to the same SAN?
