Hi all,
I recently added a DS2246 to our existing FAS3220 HA pair running 7-mode. The new shelf contains 20 SAS and 4 SSD disks with the intent of adding some needed IOPS to our existing infrastructure which was originally built solely wth SATA (2 DS4246 full of SATA drives).
My question is how best to "engineer" the flash pool(s) so that the performance benefit is seen across the aggregates and volumes that already exist.
Our setup is rather simple at this point, we have an aggr0 on each controller with VMFS volumes contained in each. My thought is to do something such as adding 2 SSD and 3 SAS to each of the aggregates and then putting them in a flash pool so that the benefits of our new SSD and SAS drives are equally spread across the entire system.
Does this make sense? Is there a better way to do this?
Thanks!
