I had just recently acquired an innovative system and am planning to re-purpose my previous one. Due to WHS 2011 being $40, I plan to reinstate the Windows 7 through it. I recognize there is not an upgrading path commencing from 7 to WHS 2011 so I am determine to do a clean install on the primary drive. My preceding system is a Dell 530 through the Intel Core 2 Quad processor. Specs be able to be originated on dell support you merely add-ons are an ATI 4670 Video card, a multi card reader, and 4 port USB card. In addition has 4GB RAM. It has the G33/ICH9 chipset. Even though Dell merely sustained or maintained RAID 0 and 1, there was a modded BIOS that to facilitate and enabled RAID 5. I set it up through one 500GB primary drive and three 1.5TB drives in a RAID 5. For the reason that of the recent system purchase, I am not actually capable to acquire sufficient additional storage space to back up the 3TB on the RAID nor have encompassed the DVD-Rs to start backing it up in addition very time consuming. The RAID presently utilizes the Intel Matrix Storage Manager. Additional than commencing from what I read the WHS 2011 has its own RAID manager. I was speculating if I be able to just immediately install the WHS 2011, replacing the Windows 7 presently on it and the RAID might remain intact or do I back up as much as I be able to regarding 1TB of the 3TB and throw a hail that the RAID does not acquire corrupted. I have comprised previously purchased the WHS 2011 and my Windows 7 License went to the innovative system build. Need some help here, thanks in advance.
