Dear all
Sorry if it's kind of off-topic for the list but after talking
to lots of vendors I'm running out of ideas...
We are looking for JBOD systems which

Following up on some of this forum's discussions, I read the manuals on
SuperMicro's
SC847E26-RJBOD1 this weekend.
At the very least, this box provides dual-expander backplanes (2 BPs for a
total of
45 hot-swap disks), so each JBOD has 4 outgoing SFF8087 (4xSATA iPass)

So if your application can live with the unit of failover being a bunch of 21

Hi Bill,
I'm assuming you've already upgraded to a Solaris 10 release that supports a UFS
to ZFS migration...

We see quite a few of these in the NexentaStor installed base. The other
