Can we use FAST Cache Spare for Data SSD Drives and vice versa
Hi All,
In VNX2 Models, can we FAST Cache Spare for Data Flash Spare. In my way we can't use why because FAST Cache drives are SLC drives and Data SSD drives were MLC & eMLC drives. can somebody through a light on this..
Thansk in advance

If you're only using 4, keep them together on DAE 0 on one of the busses.
3 simple recommendations;
For VNX Series arrays with MCx (Release 33), the best practices for drive placement, are:

No, you must have a spare(s) for each EFD type. They are not interchangeable.
