We have a FAS2020 with 2 controllers and 12 x 1.0Tb SATA drives with the following configuration:
I have just added a DS14mk4 with 14 x 600Gb SAS disks and linked them with FC to both controllers. I plan to store databases and other fast access applications on the SAS disks as the read latency on the SATAs can be pretty poor.
I would like to maximise the amount of storage space that I have and get the best performance and reliability from our systems so I was planning to build an aggregate with all the SAS disks on one controller and rebuild a single aggregate of the SATA disks on the other.
My question is regarding the HA side of things:
If I configure the system as proposed will the HA still work or do the disks for both the internal and the storage tray need to be spread equally among the controllers?
for example, should I configure:
or can I configure:
and still retain the active/active HA?
