So, if I may, is this the correct summary of the answer to original
question (on JBOD for a ZFS HA cluster):
===
SC847E26-RJBOD1 with dual-ported SAS drives are known
to work in a failover HA storage scenario, allowing both servers
(HBAs) access to each single SAS drive individually, so
Thomas,
You can consider the DataON DNS-1600(4U 24 3.5 Bay 6Gb/s SAS JBOD). It is
perfect for ZFS storage as the alternative of J4400.

And we recommend you to use native SAS HD like Seagate Constellation ES 2TB
SAS to connect 2 hosts for fail-over
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
(1) hold 20+ 3.3 SATA drives
(2) are rack mountable
(3) have all the nive hot-swap stuff
(4) allow 2 hosts to connect via
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)
connectors.
However it
Thanks Jim and all the other who have replied so far

So if your application can live with the unit of failover being a bunch of 21
or 24 disks -
that might be a way to go. However each head would only have one connection to
each backplane,

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

seen these boxes live - if you don't mind ;)

We also commonly see the dual-expander backplanes.

Dunno about Germany, but LSI and DataON both have offerings. (The LSI units
are probably going fast, as LSI exits that business having sold that unit to

Nope, only one mechanical connector. A dual port cable can be used

Multipathing is handled by mpxio.
So I configure MPxIO, then feed the zpool create device

Yes, it is that simple :-)
But can two paths work in parallel to double the
