still contemplating my first storage adventure on my first Powermac 9600…
8x 10k 9GB drives via an Atto UW card and getting 40 MB/S… with 25.000 dollars for 72 gigs of storage in 1997….
life is sweet!

Hi Chris!
you sure have a point here!
make sure you know what you are doing when it comes to iScsi!

my situation:

3 seats, always editing from LOCAL storage 4×1 TB raid-0, great read an write speeds, but VERY unreliable when it comes to a HD crash.
so the nearline backup is the ZFS iscsi which is ONLY connected to 1 seat.
this seat shares the storage via AFP to the other 2, still getting 100 MB/sec transfer rates..
with TCP offloading one doesn’t notice performance issues in a normal everyday situation on the 1st seat that is sharing.
on the other hand “very unreliable” these sets have been running for 3 years without any HD crashing…
but I am pretty paranoid about losing data, this is why the ZFS nearline and LTO are in place.

kind regards,

Frank

Hi Marcus,

I have been fiddling around with Openindana and napp-it
started as a hobby project to explore ZFS

an old gigabyte (2008) ma-785 mobo and a phenom quad-core and only 8 gis of ram
6 x 2 TB seagate as a raidz
onboard sata and a supermicro controller and lsi FC controller
worked like a charm on windows machines,
however could not get the fibre channel card to work on my hackintosh,
replaced the FC cards with 4 port quad gigabit, same on the hackintosh.
SNS iscsi initiator on the mac.

works like a charm! read speeds via BMD and Aja system test around 280 Megabytes/sec sustained.
write speeds around 100 MB/sec.

because the machine was rock-solid exchanged the 2 TB drives with 12 x 3TB seagates RAIDZ2
had to change the supermicro controller because of the 2 TB limit, to a M1015 IBM in IT mode

no luck with jumbo frames so far…..

tried editing from the storage of this machine with FCP-7 and X no problems!
the trick is using iscsi instead of AFP/SMB/NFS there is to much latency here.

not bad for a 27TB nearline backup, next to LTO tapes of course!

kind regards, Frank
