eg
I have 8936GB of Total Raw FC capacity.
I've created a 1024GB TPVV for some test VMs, this VV shows a Virtual Size of 1024GB (so far so good), a Used User Size of 551GB (TP at work), but if I look at the Physical Disk Allocated Capacity, it says 3362GB, with Free Capacity of 5574GB.
I expect a bit of overhead, but 3362GB of raw disk being consumed for a 1024GB VV is a bit rough?
Is there a way to approximate how much raw disk should be used? I realise there are a lot of variables, but even a ballpark formula would be good. I'm using mostly default options (R5 3+1), copy space is selected, does this effectively double the allocated raw space?
Edit:
I think I've made sense of it. I believe the "spares" are allocated at the beginning. So because I have 8936GB Raw, the CPG (?) has reserved 2234GB for spares, and 6702GB for usable (ie 3+1).
Got to get out of the EVA mindset and more into 3PAR
