Hi,

I would like to ask you limits of support pool quantities on ZFS storage.

Background of question.


ZFS storage has a design for resilvering at once, it needs to be entire pool scanning.

If ZFSSA(ZS3-2) had 8 full boxs (in case of DE2-24P) and used RAID-DP profile for pool, if it was create only one pool.
there be sixteen vdev groups and 144 data disks and 32 parity disks and 16 spares.
If there be a fault disk under 80% stored data in the pool, It will be quite a long time to resilver complete.
Most of customers have had a complain about the long disk recovery times.

Howdy, Stranger!
