Rocky,
Does DataON manufacture these units or they LSI OEM?

Nice write-up, Marc.
Aren't the SuperMicro cards their funny "UIO" form factor? Wouldn't want
someone buying a card that won't work in a standard chassis.

Hi Michael,
What makes you think striping the SSDs would be faster than round-robin?

You'd run out of LUN IDs on the VMware side pretty quickly (255 from
what I remember).
It's also not really VMware best practice for block.

Richard,
My challenge to you is that at least three vedors that I know of built
their storage platforms on FreeBSD. One of them sells $4bn/year of

Personally, I'd go with the Intel product...but save a few more pennies up
and get the X-25M. The extra boost on read and write performance is

Run Bonnie++. You can install it with the Sun package manger and it'll
appear under /usr/benchmarks/bonnie++
Look for the command line I posted a couple of days back for a decent set of
flags to truly rate performance (using sync writes).

Anyone else got stats to share?
Note: the below is 4*Caviar Black 500GB drives, 1*Intel x-25m setup as both
ZIL and L2ARC, decent ASUS mobo, 2GB of fast RAM.

This is a Windows box, not a DB that flushes every write.
The drives are capable of over 2000 IOPS (albeit with high latency as
its NCQ that gets you there) which would mean, even with sync flushes,
8-9MB/sec.

How does lowering the flush interval help? If he can't ingress data
fast enough, faster flushing is a Bad Thibg(tm).

At home I'm using 4*WD Caviar Blacks on an AMD Phenom x4 @ 1.Ghz and
only 2GB of RAM. I'm running svn132. No HBA - onboard SB700 SATA

I can, with IOmeter, saturate GigE from my WinXP laptop via iSCSI.

Four cores @ 1.8Ghz = 7.2Ghz of threaded performance ([Open]Solaris is

Very interesting stats -- thanks for taking the time and trouble to share
them!
One thing I found interesting is that the Gen 2 X25-M has higher write IOPS
than the X25-E according to Intel's documentation (6,600 IOPS for 4K writes
versus 3,300 IOPS for 4K writes on the "E"). I wonder if it'd perf
I would go with cores (threads) rather than clock speed here. My home system
is a 4-core AMD @ 1.8Ghz and performs well.
I wouldn't use drives that big and you should be aware of the overheads of
RaidZ[x].

As I previously mentioned, I'm pretty happy with the 500GB Caviar
Blacks that I have :)
One word of caution: failure and rebuild times with 1TB+ drives can be
a concern. How many spindles were you planning?

I believe magical unicorn controllers and drives are both bug-free and

I'm running the 500GB models myself, but I wouldn't say they're overly
noisyand I've been doing ZFS/iSCSI/IOMeter/Bonnie++ stress testing with
them.
They "whine" rather than "click" FYI.

I agree wholeheartedlyyou're paying to make the problem "go away" in an
expedient manner. That said, I see how much we spend on NetApp storage at
work and it makes me shudder ;)
I think someone was wondering if the large storage vendors have their own
