i have a customer with 2 servers one is old at least 7 years and the other is 5 years old. The Main DC Servers Roles are DNS, DHCP, AD, Printing, and File Server. The customer doesn't use a lot of space (less then 300GB of data). The Secondary DC's Roles are Print, DHCP, and DNS.
Main Server Specs are
Chassis - Intel SC5299BRP
Mobo - Intel S3420GP(LC)
PSU - Dual 610W
CPU - Intel® Xeon® Processor X3430 (8M Cache, 2.40 GHz)
RAM - 12GB
RAID - Intel SRCSATAWB
HotSwap Cage - 6 Drive Hotswap Cage
HDDs - 6 - 500GB SATA Enterprise 7200 RPM Seagate Constellation ES ST3500514NS FW SN11
Bios and Firmwares are at the latest as of today.
Secondary server specs are just basic server that i will leave as a backup DC.
I would like to reuse the Intel Server since its in good shape and i have spare parts for it. I would like to setup Esxi 5.1 Update 2 since that is what is in the compatibility list. I did install 5.5 Update 2 and tested it with 2 VMs and it seemed to work fine in a test environment but i dont think i should do that in a production env. What are your thoughts would you go with esxi or just a standard windows server 2008 install?
