Hello!
I have built a OpenSolaris / ZFS based storage system for one of our
customers. The configuration is about this:
Motherboard/CPU: SuperMicro X7SBE / Xeon (something, sorry - can't
remember and do not have my specification nearby)
RAM: 8GB ECC (X7SBE won't take more)
Drives for storag
hello
i would say: it depends
if you fill your pool with large videos or media files,
i suppose its ok, but if you have things like databases or webserver,
you will need only good iops values, much more than you can have with spindles.
(ssd could be 100x better than disks for this use)

Our experience has been that a new out of the box SSD works well for the ZIL
but as soon as it's completely full, performance drops to slower than a regular
SAS hard drive due to the write performance penalty in their fundamental
design, their LBA map strategy and the not yet released (to me at

Thanks everyone for the suggestions. To summarize:
* There's no point in using SSD's for the operating system (except an
incredibly fast boot speed, and probably a bit lower system system
temperature / power usage - but because of the rest of the components in
the system it doesn't matter). I

I agree. Our product the DDRdrive X1, an NVRAM based SSD, is
definitely not targeted towards the home end-user. By nature of our
component choices, fabrication tech, and ultimately price point we are a
ZIL
