An EMC VNX with EMC FAST Suite will be used as block storage for four Exchange 2010 servers.
The Exchange servers will be used as mailbox and archive servers. The VNX has the following
disks in two DAEs:
– Five 200 GB Flash drives
– Fifteen 600 GB SAS drives
– Ten 2 TB NL-SAS drives
The customer wants to implement auto-tiering. What do you advise the customer?

A.
Retrieving an archived email will force moving the whole Archive mailbox to EFD disks.

B.
Storage tiering is not recommended because of Exchange 2010 BDM operations.

C.
Auto-tiering works only when every disk type group is installed in a separate DAE.

D.
There is no benefit to using auto-tiering with an archive solution.
