Experience with Promise Tech. arrays/jbod''s?
Greetings,
In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve
run across the recent "VTrak" SAS/SATA systems from Promise Technologies,
specifically their E-class and J-class series:

Seagate Constellation vs. Hitachi Ultrastar
Happy Friday, List!
I''m spec''ing out a Thumper-esque solution and having trouble finding my favorite Hitachi Ultrastar 2TB drives at a reasonable post-flood price. The Seagate Constellations seem pretty reasonable given the market circumstances but I don''t have any experience with them. Anybody using these in their ZFS systems and have you had good luck?

Sun 6120 array again
Greetings,
Last April, in this discussion...
http://www.opensolaris.org/jive/thread.jspa?messageID=143517
...we never found out how (or if) the Sun 6120 (T4) array can be configured
to ignore cache flush (sync-cache) requests from hosts. We''re about to
reconfigure a 6120 here for use with ZFS (S10U4), and the evil tuneable
zfs_nocacheflush is not going to serve us well (there is a ZFS

Desperate question about MPXIO with ZFS-iSCSI
I''m trying to set up a iscsi connection (with MPXIO) between my Vista64 workstation and a ZFS storage machine running OpenSolaris 10 (forget the exact version).
On the ZFS machines, I have two NICS. NIC #1 is 192.168.1.102, and NIC #2 is 192.168.2.102. The NICs are connected to two separate switches serving two separate IP spaces.
On my Vista64 machine, I also have two NICs connected in

Hi,
I just deploy the ZFS on an SAN attach disk array and it''s working fine.
How do i get dual pathing advantage of the disk ( like DMP in Veritas).
Can someone point to correct doc and setup.
Thanks in Advance.

Un/Expected ZFS performance?
I''m running Postgresql (v8.1.10) on Solaris 10 (Sparc) from within a non-global zone. I originally had the database "storage" in the non-global zone (e.g. /var/local/pgsql/data on a UFS filesystem) and was getting performance of "X" (e.g. from a TPC-like application: http://www.tpc.org). I then wanted to try relocating the database storage from the zone (UFS

ZFS and multipath with iSCSI
We''re currently designing a ZFS fileserver environment with iSCSI based
storage (for failover, cost, ease of expansion, and so on). As part of
this we would like to use multipathing for extra reliability, and I am
not sure how we want to configure it.
Our iSCSI backend only supports multiple sessions per target, not
multiple connections per session (and my understanding is that the

How to delegate filesystems from different pools to non-global zone
I''m trying to add filesystems from two different pools to a zone but can''t seem to find any mention of how to do this in the docs.
I tried this but the second set overwrites the first one.
add dataset
set name=pool1/fs1
set name=pool2/fs2
end
Is this possible or do I need to use different syntax?

Identifying firmware version of SATA controller (LSI)
Trying to track down why our two Intel X-25E''s are spewing out
Write/Retryable errors when being used as a ZIL (mirrored). The
system is running a LSI1068E controller with LSISASx36 expander
(box built by Silicon Mechanics).
The drives are fairly new, and it seems odd that both of the pair would
start showing errors at the same time....

WD caviar/mpt issues
I know that this has been well-discussed already, but it''s been a few months - WD caviars with mpt/mpt_sas generating lots of retryable read errors, spitting out lots of beloved " Log info 31080000 received for target" messages, and just generally not working right.

SAN arrays with NVRAM cache : ZIL and zfs_nocacheflush
Hi,
I read some articles on solarisinternals.com like "ZFS_Evil_Tuning_Guide" on http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide . They clearly suggest to disable cache flush http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#FLUSH .
It seems to be the only serious article on the net about this subject.

Any rhyme or reason to disk dev names?
Hello,
I am curious to know if there is an easy way to guess or identify the
device names of disks. Previously the /dev/dsk/c0t0d0s0 system made sense
to me... I had a SATA controller card with 8 ports, and they showed up with
the numbers 1-8 in the "t" position of the device name.
But I just built a new system with two LSI SAS HBAs in it, and my device
names are along the lines of:

ZFS vs mpxio vs cfgadm in Solaris.
Folks,
I''m trying to figure out whether we should give ZFS / mpxio a shot
on one of our research servers, or simply skip it (as we have
previously).
