70TB of ZFS on JR5-96Tn.

[updated] to answer the questions on pricing, yes, this is less than $1 USD/usable-GB for this system.

And for some simple speed pr0n

/usr/bin/time dd if=/dev/zero of=/tank/big.file ...
1024+0 records in
1024+0 records out

real       14.8
user        0.0
sys        14.0

16GB in 14.8 seconds. 1.1GB/s Unfortunately, this is cached. So the next result shouldn’t surprise you.

scalable@jr5-96TB:~# /usr/bin/time dd if=/tank/big.file of=/dev/null ...
1024+0 records in
1024+0 records out

real        4.2
user        0.0
sys         4.2

4.2 s to read 16GB. Or 3.8 GB/s out of cache.

Lets try 128 GB, and see what happens.

scalable@jr5-96TB:~# /usr/bin/time dd if=/dev/zero of=/tank/big.file ...
8192+0 records in
8192+0 records out

real     2:23.3
user        0.0
sys      2:07.6

Excellent. This is 143.3 seconds, for 890 MB/s way outside cache. Lets try the read version of this …

scalable@jr5-96TB:~# /usr/bin/time dd if=/tank/big.file of=/dev/null ...
8192+0 records in
8192+0 records out

real     2:17.5
user        0.0
sys      1:31.8

This is 137.5 seconds to read 128 GB. Reads at 931 MB/s.

You can see the Linux results here on this exact same hardware in a previous post or two, if you need comparisons.

Why OpenSolaris 2009.06 and not Solaris? We can’t put benchmark numbers out about the latter, but can with the former. Why not NexentaStor? We have to get a supported ethernet card into the machine for that. The igb driver appears to be too new for their 2.0 release. I’ll bug them about this.
