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
product - petty sure that eclipses all (Open)Solaris-based storage ;)

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.

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

Nice write-up, Marc.

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

I'm running the 500GB models myself, but I wouldn't say they're overly

I believe magical unicorn controllers and drives are both bug-free and
100% spec compliant. The leprichorns sell them if you're trying to
find them ;)

One word of caution: failure and rebuild times with 1TB+ drives can be
a concern. How many spindles were you planning?

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].

Very interesting stats -- thanks for taking the time and trouble to share

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

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

Definitely use Comstar as Tim says.
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
ports.$
I can, with IOmeter, saturate GigE from my WinXP laptop via iSCSI.

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.

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).
