Hello chrisatdl If you are using a PERC 6 then yes, a PERC 6 supports up to 2TB HDDs. I can't say for certain whether the drives you listed will function, but we have validated the PERC 6 to function with 2TB HDDs. There may be an issue with running the RAID 5 configuration. You will not be able to install the host OS on the RAID 5 volume because that volume will exceed the 2TB BIOS limitation. The 2900 system board does not have UEFI, and does not support booting to larger than 2TB arrays/HDDs. You can create very large data arrays, but the array you boot from needs to be 2TB or smaller. The easiest way to bypass this would be to install ESXi onto a thumb drive, and run it from there. You can then create a data array of whatever size you like. Refer to this document for more information on GPT and UEFI in ESXi: [URL] Thanks
I'm basically trying to replace our failed Seagate 750 GB SATA drives and start over with 3 more cheap SATA drives off the shelf from a local vendor.  This server is basically used for test purposes in a VMWare ESXi environment, but would come into play as a very temporary backup server solution to our main 2950 which houses our Windows SBS 2008 application.  My question is this: Can I use 2TB 7200 RPM SATA drives like a Seagate Barracuda or a Western Digital Green?  I want to continue running a RAID 5 configuration if that matters at all to the question. Thanks in advance.
