A Big Server Upgrade – 21TB to be Exact
PCDoc wanted to upgrade his WHS 2011 box with faster and larger hard drives and after a lot of research settled on the Seagate ST3000DM001 3TB drives – 6 of them enabling him to have 21TB of storage.
PCDoc goes through his upgrade process using a copy of AllwaySync and gives us the results of the Seagate’s in a RAID5 setup which you can find here.

not exactly, had to actually read the article to understand how he could get 21TB from 6 3TB drives ;-)… the math doesn’t add up, does it?
His system has the ability to be expanded up to 21TB, as he has 8 bays available and an 8-port RAID controller: using 3TB disks that would be 24TB, but since he’s running a RAID5 setup that would be 21TB max expandable…. but that’s the future.
As it sits now, he’s running 6 3TB disks in RAID5, one is a hot spare, so there are actually 5 active disks in that RAID5 configuration… giving him 12TB actual storage in this upgrade as it sits now.
Thank you phaze for clarifying the total storage amount for me
Thanks for the clarification and the comments. You are correct as it is for future expansion which is not that far away.
