Hi Brian,
If you are considering testing dedup, particularly on large datasets,
see the list of known issues, here:
http://hub.opensolaris.org/bin/view/Community+Group+zfs/dedup
Start with build 132.
Thanks,
Cindy

I am Starting to put together a home NAS server that will have the following
roles:
(1) Store TV recordings from SageTV over either iSCSI or CIFS. Up to 4 or 5 HD
streams at a time. These will be streamed live to the NAS box during recording.
(2) Playback TV (could be stream being recorded, could be others) to 3 or more
extenders
(3) Hold a music repository
(4) Hold backups from windows machines, mac (time machine), linux.
(5) Be an iSCSI target for several different Virtual Boxes.
Function 4 will use compression and deduplication.
Function 5 will use deduplication.
I plan to start with 5 1.5 TB drives in a raidz2 configuration and 2 mirrored boot drives.
I have been reading these forums off and on for about 6 months trying to figure
out how to best piece together this system.
I am first trying to select the CPU. I am leaning towards AMD because of ECC
support and power consumption.
For items such as de-dupliciation, compression, checksums etc. Is it better to
get a faster clock speed or should I consider more cores? I know certain
functions such as compression may run on multiple cores.
I have so far narrowed it down to:
AMD Phenom II X2 550 Black Edition Callisto 3.1GHz
and
AMD Phenom X4 9150e Agena 1.8GHz Socket AM2+ 65W Quad-Core
As they are roughly the same price.
