It looks like this refers to the ability to use the TRIM command, but ZFS
doesn't:

Agreed, SSD with SandForce controllers are the only way to go. The
controller makes a world of difference.

I am waiting for the next gen Intel SSD drives, G3. They are arriving very
soon. And from what I can infer by reading here, I can use it without issues.
Solaris will recognize the Intel SDD drive without any drivers needed, or
whatever?
Intel new SSD should work with Solaris 11 Express, yes?

A word of caution on the Silicon Image 3124. I have tested out a two
extremely cheap card using the si3124 driver on b134 and OIb147. One card
was PCI, the other PCI-X. I found that both are unusable until the driver
is updated. Large'ish file transfers, say over 1GB would lock up the

Without top level ZFS TRIM support, SATA Framework (sata.c) support
has no bearing on this discussion.

Hello,
A ZFS VDI related question. I'm exporting an iscsi share from a linux
box which i'm mounting on a Solaris 10 VDI broker and subsequently used
by the desktop providers. This is for a proof of concept. This works
fine under VDI 3.2.1 until i reboot the VDI broker.
After the broker rebo

Because ZFS does *not* support TRIM, so the benchmarks
are configured to replicate actual ZIL Accelerator workloads.

"Your system drive on a Solaris system generally doesn't see enough I/O
activity to require the kind of IOPS you can get out of most modern SSD's. "
My system drive sees a lot of activity, to the degree everything is going slow.

I recently presented at the OpenStorage Summit 2010 and compared
exactly the three devices you mention in your post (Vertex 2 EX,
Vertex 2 Pro, and the DDRdrive X1) as ZIL Accelerators.

A noob question:
These drives that people talk about, can you use them as a system disc too?
Install Solaris 11 Express on them? Or can you only use them as a L2ARC or Zil?
