#ADPv2 on FAS8300

We have a number of new 15TB SSD shelves now distributed evenly among (2 ea) FAS8300 MC-IP nodes and I was hoping to use these to migrate away from some SATA root aggregates using ADPv2 and I have a nice procedure here, but the docs (TR's and HWU) say it isn't supported. Have I hit a show-stopper?

Migrating the root aggregate from spinning disks to SSD only makes sense if you're getting rid of all spinning disks. Otherwise I'd leave it on the slow disks (it doesn't need to be fast).
As for the RD2 partitioning, there is an ADP FAQ on Field Portal that you might want to take a look at. ADPv2 is officially only supported on AFF and all-SSD FAS systems. So the system will not help you partition the SSDs. You have to partition them manually, that will work. But it's a bit complicated.

the plan is to get rid of HDD in the next 6-9 months towards a hardware refresh that will probably be AFF, but the HDD's don't have much practical use with the size of our StorageGrid setup. I have all the docs (afaik) for the partitioning, I just don't want to paint myself into a corner. I've spent a good deal of time mapping out all the disks and what their cluster and node paths are, but since this seems to be somewhat uncharted territory, there are some holes. I guess I'll have to wait for the PSE guy to get back from vacation, which sort of blows as migrating volumes would work well with the low load over the holidays.

Yes, ADP is supported on AFF and all-SSD FAS systems, but not when in a MCCIP configuration.

If your system is a FAS in an MCCIP configuration, ADP is **not ** supported. This is outlined in both the ADP Technical FAQ and ADP SE Presentation on Field Portal.

  1. Thanks for confirming what the docs (unfortunately not always reliable) say.
  2. Disappointing.
  3. I'd ask "why", but I sort of doubt I'm going to get much of a technical answer and it won't change anything. The line seems somewhat arbitrary.
  4. One of many things that make "evolutionary" changes to storage upgrades more difficult.

You're welcome. Good luck!
