If i'm not mistaken (and somebody please correct me if i'm wrong), the
Sun 7000 series storage appliances (the Fishworks boxes) use enterprise
SSDs, with dram caching. One such product is made by STEC.
My understanding is that the Sun appliances use one SSD for the ZIL, and
one as a read cache.
This is correct, and you can read about it here:

That's my understanding too. One (STEC?) drive as a write cache,
basically a write optimised SSD. And cheaper, larger, read optimised
SSD's for the read cache.
I thought it was an odd strategy until I read into SSD's a little more
and realised you really do have to think about your usage cases w

But the "fishworks" (Fishworks is a development team, not a product)
write cache device is not based on FLASH
However, now I've written that, Sun use SATA (SAS?) SSD's in their high end
fishworks storage, so I guess it definately works for some use cases.

I don't have an x4540, and this may not be relevant to your usage, but the
concern I would have would be how this is going to affect throughput. An x4540
can stream data to and from the disk far faster than any SATA SSD, or even a
pair of SATA SSD's can. I'd be nervous about improving my laten
We're evaluating the possibility of speeding up NFS operations of our
X4540s with dedicated log devices. What we are specifically evaluating
is replacing 1 or two of our spare sata disks with sata SSDs.
Has anybody tried using SSD device(s) as dedicated ZIL devices in a
X4540? Are there any kno
