ReadyTIER with ReadyNAS Pro 6
Hi,
I've got a NAS Pro 6-bay system, currently on NASOS 6.9.5 hotfix 1 and loaded with 4 x WD RED 8 TB drives in FlexRAID RAID 5. Primary use case for the unit is as an NFS server for my VMwar...

So...here's my putting-the-cart-before-the-horse question: Do you know of any reason this shouldn't work when adding a 512 GB RAID1 SSD tier to the existing volume?
It should work in the Pro-6 (though you do need to change to flexraid in order to use ReadyTier).
The main challenge is adapting the trays for the SSDs, and you've already found mounting brackets for that part.
ReadyTier isn't caching the metadata, so if the SSD RAID group fails you will lose the volume. Your SSDs will reach their write limits at the same time. So you might want to replace one of them about half-way through it's expected life, so you can stagger the replacements.
Yeah, VMware's datastore stats are showing an average so far of 7.2mS read and 1.4 mS write latency...that's good enough I'd run a small production SQL box on it even if it was physical hardware, much less virtualized.
I'll shut up now. :)
