The FusionIO MLC PCI-e device I tested is capacitor backed (just not
super-cap). The OCZ Deneva SATA SSD I tested is super-cap backed.

Or it could just be that the Samsung drive you tested has something
seriously wrong with it.

primary fails, your
secondary can take over as the primary but the disks remain in the
secondary state. There is no way to reverse the replication while the
secondary is acting as the primary."
Is AVS even the right solution here, or should I be looking at some
other tech
Hi all, I have a ZFS question related to COW and scope.
If user A is reading a file while user B is writing to the same file,
when do the changes introduced by user B become visible to everyone?
Is there a block level scope, or file level, or something else?
Thanks!

I'm having the same problem after adding 2 SSD disks to my machine.
The controller is LSI SAS9211-8i PCI Express.

a SOLARIS2 type partition on it. It worked and no more crash
during format command.
Cindy, please let the format team know about this since I'm sure
others will also run into this problem at some point if they have a
mixed Linux/Solaris environment.

I have this with 36 2TB drives (and 2 separate boot drives).

It's not exactly the same (it has cons/pros), but it is definitely
less expensive. I'm running b147 on it with an LSI controller.

I tested the Fusion IO MLC based PCI-e cards on OpenSolaris and found
the performance to be amazing. Hopefully Fusion IO will release
supported drivers for Solaris 11 Express and onwards. The Fusion IO
MLC card was giving me around 500MB/s write performance with O_SYNC.

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

So, is it OK to send/recv while having the receive volume write enabled?

reading almost nothing. How can this be the
case?
So I'm left with 2 questions -
1.) Does ZFS get immensely slow once we have thousands of filesystems?
2.) Why do we see 4MB-8MB/s of *writes* to the filesystem when we do a
'zfs send' to /dev/null ?

Well, he did say fairly cheap. the ST 3511 is about $18.5k. That's
about the same price for the low-end NetApp FAS250 unit.

Hi all,
I'm thinking of using an Enhance 1U R4 SA eSATA storage device with
my Solaris 10 based Sun X2100 box. Has anyone used this before and
have any experiences you could share? The device starts at about $450.

Thanks.
