Hi esteemed ladies and gentleman...
I have a couple of questions which I am currently googling which I
would value people's opinion on:
1. Never having used NAS before, I am looking to find out the relative
performance benefits of NAS as opposed to the plain ole' linux box
file server, and
Most NAS's are a plain ole' linux file server.... make up your own mind
as to the performance of that :)
2. kinda related, are SATA drives now good enough to use instead of
SCSI (in a RAID)?
Yes, but I would recommend RAID6 in a decent CPU machine. Multiple
concurrent failures are less and less common these days and really bite
hard on RAID5..
The particular application I am looking to use it with is where I
would guarantee 40-50 concurrent users accessing files of the storage
unit at once.
Open sessions isn't a problem, size and frequency of file transfers is
the only thing you need to optimise for. Shouldn't be a problem on a
machine with 4 hdds in raid6 (linux software raid of course) and samba.
should fly along.
FWIW, I have setup an HA version of this recently and recent with some
hardware was giving me excellent throughput on Gigabit networks (haven't
got numbers on hand) but I was very impressed. 750GB SATAs i used. try
and get a board and drives that supports NCQ, with a recent kernel for
drivers, and you will get decent performance too...
