Hi all.
I've been running the ZFS boot netinstall setup on SXCE's snv_69 and
snv_70 very happily. I'm anticipating the release of xVM with build 75,
and wondering if the same ZFS install procedure is likely to work, or if
I'll be left waiting further for more changes.
I understand that this
Hey all,
Has anyone else noticed Norco's recently-announced DS-520 and thought
ZFS-ish thoughts? It's a five-SATA, Celeron-based desktop NAS that ships
without an OS.

What practical impact is a 32-bit processor going to

Because it offers upto 1GB of memory, 32bit shouldn't be an issue.
Sorry, could someone expand on this?
The only received opinion I've seen on 32-bit is from the ZFS best
practice wiki, which simply says Run ZFS on a system that runs a 64-bit
kernel. I

If you don't have a 64bit cpu, add more ram(tm).
Actually, no; if you have a 32 bit CPU, you must not add too much
RAM or the kernel will run out of space to put things.
Hrm. Do you have a working definition of too much?

Norco usually uses Silicon Image based SATA controllers.
Ah, yes, I remember hearing SI SATA multiplexer horror stories when I
was researching storage possibilities.
However, I just heard back from Norco:
Thank you for interest in Norco products.

Well, noticeable again comes back to
Back in April, I pinged this list[1] for help in specifying a ZFS server
that would handle high-capacity reads and writes. That server was
finally built and delivered, and I've blogged the results[2] as part of
a larger series[3] about that server.

Fun exercise! :)
I'm thinking about using this 26-disk case: [FYI: 2-disk RAID1 for the
OS 4*(4+2) RAIDZ2 for SAN]
What are you *most* interested in for this server? Reliability?

Capacity? High Performance? Reading or writing? Large contiguous reads
or small seeks?
One thing that I did that got a good feedback from this list was
picking apart the requirements of the most demanding

Mm. yeah, it's what I was worried about, too (mostly through ignorance
of the issues), which is why I was hoping HyperTransport and PCIe were
going to

Hi folks. I'm looking at putting together a 16-disk ZFS array as a server, and
after reading Richard Elling's writings on the matter, I'm now left wondering
if it'll have the performance we expect of such a server. Looking at his
figures, 5x 3-disk RAIDZ sets seems like it *might* be made to do

In asking about ZFS performance in streaming IO situations, discussion
quite quickly turned to potential bottlenecks. By coincidence, I was
wondering about the same thing.
