RE: Power 9 upgrades and GA2.

Always good to look at new vs existing when it comes to SSDs.

When bringing over older SSDs, something it is a good idea to look at the cost of their maintenance over 3 years vs purchasing new SSDs that come with maintenance. The on-going maintenance for the newer SSDs is much cheaper than the older SSDs. Of course, depending on the generation of SSDs, this can even be more of a dramatic difference.

My boss got it from our BP.

Our sandbox 41A only has two 5887's. One with regular spinning disks, one with huge slower spinning disks we use for archiving. That's on hold for now Backup 41A has two 5887s with 21TB of older SSD's and two newer enclosures with ~21TB of newer SSD's. We lose the older SSD's for now.
Primary 42A has the same disk config as the backup 41A and it's in the same boat.

Rob,

How and where did you find this?
I was planning on doing something similar.

Because I'm bringing the 5887 EXP24S with its SSDs from our current P7, it
would not be in the configurator.

I've just found out that 5887 disk drawers will not be initially supported
on Power 9's.
This will postpone one of our Power 9 upgrades until GA2.
And I will have to chop our disk availability in half on our other two
Power upgrades until then.
Nothing like leaving 21TB of SSD "on the shelf" on EACH of the two other
Power 8-9 upgrades.

For those thinking of using a Power 9 upgrade to cover the maintenance of
older SSD's you'd better make sure those older SSD's are not in 5887's.
