Primera M.2 on main board

[AHAH]

Hi
In primera 630 we have one M.2 for boot image and store cache when Power failure or erc.
But in 650 and 670 we have two M.2 for what?
One for boot image and another for Cache?
It's True?

Hi Ahah,

No, they are redundant physical drives. Both contain a separate instance of the HPE Primera OS (as well as space to save cached write data in the event of a power failure).  This is to ensure the node will work even though any of the boot drives encounters any issue.

Hi Ahah,

This is mentioned in the Primera Technical whitepaper - HPE Primera architecture technical white paper page 9
