Since the birth of the ODA X6-2 HA, the net usable storage has become more of a challenge when advising a customer as the X5-2 HA had substantial more – but slower – storage. This very short blogpost is just a quick summary / checklist of the net usable storage, depending on the ODA and the mirroring you choose.
By the way, for other ODA-comparisons than storage I wrote another blogpost.
The following pictures are extracts of Oracle PDF’s.
Usable storage of the single node ODA’s:
Usable storage of the two-node ODA (including the ‘old’ X5-2 HA for comparison):
ODA X6-2 HA Normal Redundancy – 2 x Mirroring
ODA X6-2 HA High Redundancy – 3 x Mirroring
