RAID-6 partition limit

210 Views
Last Modified: 2017-04-25
Hello.
I have purchased a Fujitsu server.
I have 6 HDD 2TB and created RAID-6. I need to install Windows Server 2012R2. During installation I created 100GB partition for system, and then windows setup split rest of free space to two unallocated free space. I need that space all for one partition.
Are there some restrictions to size of partition or am I doing do something wrong?

Just to clarify, RAID-x does not, inherently, impose *any* size limits on the array.  That's not to say that the controllers can't access individual drives beyond a certain size which therefore imposes a controller limit on the size of the array.

The file system, however, can (and does) impose a size limit on the logical drive volume.

Partitions are bad.  create RAID VOLUMES.  Store you VMs on a separate volume from the host os.
