Disabling the ZIL (Don't) br
Caution: Disabling the ZIL on an NFS server can lead to client side corruption.
The ZFS pool integrity itself is not compromised by this tuning. brbr

i have the same problem with my 2HE supermicro server (24x2,5, connected via
6x mini SAS 8087) and no additional mounting possibilities for 2,5 or 3,5
drives.
brbr
on those machines i use one sas port (4 drives) of an old adaptec 3805 (i have
used them in my pre zfs-times) to build a raid-1 +
Also, most of the big name vendors have a USB or SD
option for booting ESXi. I believe this is the 'ESXi
Embedded' flavor vs. the typical 'ESXi Installable'
that we're used to. I don't think it's a bad idea at
all. I've got a not-quite-production system I'm
booting off USB right now, and
Up to last year we have had 4 exsxi4 server, each with its own NFS-storage
server (NexentaStor/ Core+napp-it), directly connected via 10Gbe CX4. The
second CX4 Storage-Port was connected to our San (Hp 2910 10Gbe Switch) for
backups. The second port of each ESXI Server was connected (tagged

definitely ok) but i could not bring the
hello
i would say: it depends
if you fill your pool with large videos or media files,
i suppose its ok, but if you have things like databases or webserver,
you will need only good iops values, much more than you can have with spindles.
(ssd could be 100x better than disks for this use)

hi br
as already said above. zfs property shareiscsi is obsolet and slow.
use comstar instead!br

be careful.br
if you switch to comstar, your current iscsi is no longer available.

you could als try napp-it, my free web-gui for

if you are looking for pci-e (8x), i would recommend sas/sata controller
with lsi 1068E sas chip. they are nearly perfect with opensolaris.
you must look for controller with it firmware (jbod mode) not
those with raid enabled (ir mode). normally the cheaper
variants are the right ones.

if you want to compair it against openfiler, i would suggest not to use
opensolaris itself (too much desktop stuff) but a more server like opensolaris

i have had this problem this week. our zil ssd died (apt slc ssd 16gb).
because we had no spare drive in stock, we ignored it.

i'm really happy to throw away all sort of tapes.

hello
you can try webadmin application napp-it.
it's a s free and end-user configurable perl-cgi script to manage your nexenta
(core), eon or opensolaris server via browser. (not only zfs, also user,
network, iscsi..).
it will support newest features of snv 129 like dedup, zfs3..
