Can you use all available space for vdisks

Hi. I have an MSA P2000 with an expansion unit. I created 2 raid6 vdisks with a hot spare each. This gives each vdisk 5.4 TB usable. My question is can I create volumes that add up to the entire 5.4 tb? I know I don't want to run my volumes at 100% capacity but will there be a performancehit if I create volumes that take all 5.4TB? Thanks, JOhn

Hey, have you read the P2000 best practices?

I couldn't find anything in there (didn't raed, just search) about if you should create volumes for the 100% space. But I don't see why not as you have a global/dynamic spare assigned right?

Then what about snapshot, Volume Copy and Snap Pool.

 

The first time a snapshot is created of a standard volume, the volume is converted to a master volume and a snap pool is created in the volume’s vdisk. The snap pool’s size is either 20% of the volume size or the minimum snap-pool size, whichever is larger. Before creating or scheduling snapshots, verify that the vdisk has enough free space to contain the snap pool.
