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.
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 + hot

Disabling the ZIL (Don't)
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.
so especially with nfs i won`t disable it.

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 Vlan

hi
as already said above. zfs property shareiscsi is obsolet and slow.
use comstar instead!
be careful.
if you switch to comstar, your current iscsi is no longer available.
save the data first. and if you want to have it more user-friendly,
you could als try napp-it, my free web-gui for opensolar
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)

hello
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.

hello
do you want to use it as a file smb-fileserver or do you want to have other
windows services? if you want to use it as a file server only, i would suggest
to use build in cifs server.
iscsi will be always slower than native cifs server and you have snapshots via
windows property previo

hello
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.
then we decided to update our nexenta 3 alpha to beta, exported the pool and
made a fresh install to have a clean system and tried to import the pool. we
only got

what i'm thinking about is:
keep it simple
1.
i'm really happy to throw away all sort of tapes.
when you need them, they are not working, are to slow ore
capacity is too small.
use hd*s instead. they are much faster, bigger, cheaper and data are much safer

you could try my napp-it zfs server
it's a zfs server, a minimal opensolaris-based server installation,

my intention was to show , how you can tune up a pool of drives

napp-it is just a simple cgi-script

hello
may i suggest my free napp-it zfs-server
it is based on free nexenta3 (core) or opensolaris/eon,
(no hd limit, deduplication, zfs3, all the new stuff)
-with user editable webgui,
-easy setup instructions (copy and run)
and a hardware reference design.

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..
see http://ww
rrors at all since the disks are mirrored.
