ME4084 - How to expand to 4PB

Question

Hello

We can only create 2 pools and each pool can only grow to 1PB at most by enabling large pools attribute in CLI.

So how will we expand to more than 2PB ? Specs says that ME4084 can grow to 4PB raw capacity.

Thanks

DellUserDD,

One other thing to add for the 4PB question;

It is a limit of virtual storage, 1PB per pool and 1 pool per controller. In linear storage mode it supports 32 pools per controller and that would allow for 4PB
