Jjbreen67, The Perc 6/i can support up to 2TB physical disks. It can have Virtual Disks larger than 2Tb, but the physical limitation is 2TB. Now with it being a R610, it will support using the H700 raid controller (part # 1THG8), which will allow you to exceed the 2TB limitation.   Let me know if this helps answer your questions.
Hi everyone  I have a Poweredge R610 with a Perc 6/i SAS controller. I would like to repurpose this as a backup server for our LAN, by filling the remaining 4 SAS drive bays with the largest compatible drives available.  Dell's information states that the largest drive the R610 that can be purchased is a 1TB 7200 RPM SAS drive. Has anyone tried a larger drive in this chassis?  Thanks for your time folks  Kind regards  John
