Best Practices Windows Server 2012 OS Partition Size
Posted on 2015-02-20
Howdy! I have thoroughly scoured the net for best answer...Decided to give the, "Experts" a crack at it.
I recently purchased a Dell T420 Server for a company I perform IT management. Totally "Cadillac" machine: Dual 2.5 GHz, 8 core processors, 6 drives (2 x 300 GB, RAID 1 and 4 x 1.2 TB, RAID 5), 128 GB Ram, Dual power supplies, etc. The machine came pre-installed with OS (Windows Server 2012 Standard R2). However, after looking at the multiple partitions on the "C" drive (2 x 300 GB, RAID 1) and seeing all the junk on board, I decided to re install the OS from scratch. Nice and clean is how I roll!
Following OS installation, updates, configuration, etc., I will be installing SQL Server 2014 Standard, on same. In addition, there will be some smaller 3rd party server hosted programs installed. The server will function as both a domain controller and file server. "D" drive, 4 x 1.2 TB, one of which is a dedicated hot spare, will house the users files.
My question: What is the recommended OS partition size taking the above into consideration? Should I use the entire 300 GB (RAID 1 is a mirrored configuration, so 2 x 300 GB drives is still 300 GB usable). Should I split the page file between C and D virtual drives? Any comments are appreciated...
