iSCSI will certainly work. so will ata-over-ethernet, nbd, and any other
solution that exports block level or interface level access. with iSCSI or
ATAoE you can format the target with a compatible filesystem. I highly
suggest you run gigabit if you are using iSCSI though, regular ethernet is
good for 12.5MB/s only. iSCSI or any of these protocals will trim off
something like 10% off the top so best case you will get about 10MB/s and
random reads and writes will have some latency added from the network so it
will 'feel' like 5-6MB/s second if you were comparing it to a local
filesystem(with small files anyway, large files dont suffer very much from
the latency)
I have run iSCSI exporting a physical disk and formating it reiserfs(be
compensate for network latency as reiserfs is great for small files) and I
have also used iSCSI on a ZFS container, as well as nbd. all work well as
long as you understand the performance level you will get.
note, you can do RAID over iSCSI and such but I would highly suggest you do
RAID1 or RAID5 or 6 as you will add the chance of network failure but the
upside is that you can spread the bandwidth over a number of ethernet
cards(hopefully gigabit) and get a much higher aggrigate bandwidth.
