Multiple ZFS SSD cache pools

[Kaizac]

Currently, I have 1 cache pool of 2 SSD's mirrored in BTRFS. I'm thinking about the configuration of my new system in which I expect to have at least 4 NVME drives and perhaps 2 SATA SSD's.

I know it is possible to make multiple cache pools right now, but is that also possible with ZFS mirroring? So I would have 2 NVME as 1 mirrored ZFS cache pool, then the 2 other NVME drives would be another ZFS mirrored cache pool. And perhaps the SATA SSD's will be another ZFS cache pool, or just single drives.

The array would stay in XFS as I want to keep the flexibility to grow my array easily.

 

Would this be possible, or is the cache pool with ZFS limited to 1?
