1 - are the 2 vdevs in the same pool, or two separate
pools?
I was planning on having the 2 z2 vdevs in one pool. Although having 2 pools
and having them sync'd sounds really good, I fear it may be overkill for the
intended purpose.

Thanks Richard.
How does ZFS enumerate the disks? In terms of listing them does it do them
logically, i.e;
controller #1 (motherboard)

|--- disk1
|--- disk2
controller #3
|--- disk3
|--- disk4
|--- disk5
|--- disk6
|--- disk7

Imagine if 2.5 2TB disks were price neutral compared to 3.5 equivalents.
I could have 40 of the buggers in my system giving 80TB raw storage! I'd

Can you find somewhere inside the case for an SSD as
L2ARC on your
last port?
Although saying that, if we are saying hot spares may be bad in my scenario, I
could ditch it and use an 3.5 SSD in the 15th drive's place?

Is it still the case, as it once was, that allocating anything other
than whole disks as vdevs forces NCQ / write cache off on the drive
(either or both, forget which, guess write cache)?

Funny you say that.
My Sun v40z connected a pair of Sun A5200 arrays running OSol 128a can't see
the enclosures. The luxadm command comes up blank.
Except for that annoyance (and similar other issues) the Sun gear works well
with a Sun operating system.

We pay for the brand-name disk enclosures or servers where the
