16 terabytes of storage on Solaris?

What's the best way of setting up a single filesystem of 16 terabytes (or
a little less), at about 64 megabytes/second sustained or better, using
Solaris? Needs to be reliable and economical, doesn't need to be blazing.
Is there such a thing as a JBOD or series of JBOD's that could be attached
to the same box and SVM'd to this kind of capacity? Or perhaps RAID
arrays that would present a series of large block devices that could be
SVM'd?
Does Solaris have anything like NBD/ENBD/AoE/iSCSI that would make remote
disks seem local (say, over GigE?), for SVM purposes?
How else might you construct such a large storage system?
Thanks!

Actually, this is not that uncommon. You can do it several ways.
1) jbod like the old A5xx arrays from Sun (in case you've got some
laying around)
2) brick arrays from vendors like Nexsan (ATABeast), HP (MSA1000),
Overland (no idea), you name it. There are a ton of these vendors out
there. Traditionally you can get 2TB per 3u shelf. As long as you
have enough cards (scsi or fc) you can chain up till you have no more.
3) Go for the monolithic array like those from HDS or EMC.
There is an iSCSI client available for Solaris but unless you have
iSCSI capable storage it won't really buy you much. My tact for
something like this would be the brick method (#2).
Of course, to do 16TB in a single file system you have to be running
64 bit Solaris. But you probably already knew that...

Infortrend has some interesting ATA based boxes that are inexpensive and
seem to work.
YMMV, I just had one in the lab for a few weeks. FWIW it seems the
controller software is also used by some Sun producs, though the
hardware is diferent.
