Is it possible to modify an existing storage pool, to allow for tiered storage configuration, following the addition of SSDs to a JBOD?
Secondly, what effect if any, does a disk with a lower rotational speed have on perhaps say, a 3-way mirror virtual disk, which is spread across other disks with the same rotational speed? Is performance compromised for the other disks as a result of the slower disk being part of the virtual disk?
Many thanks.
