Windows 2000 Server, Novell, Linux, BSD, Solaris, and probably several
others that I have forgotten about will do what you want.
When you say "redundant, failsafe", are you talking about disks or are
you talking about the whole server? Any contemporary server operating
system provides native support for some variety of RAID, which gives you
redundant disks. If you need the server to failover you can do that but
with everything except the open-source Unix variants it's going to cost
you.
With properly configured storage devices and a server with 64 bit 66 MHz
PCI Novell can saturate a gigabit Ethernet. I believe that Linux can as
well. Last I heard, Windows 2000 couldn't, but that might have changed.
Any of them can saturate 100baseT. With gigabit the transfer time for
your 40 meg image should be under half a second--with 100baseT it should
be around 5 seconds. This assumes that you have a storage configuration
that can sustain that transfer rate.
When you say "expandable storage space" do you mean that you want to be
able to increase the size of a volume at any time without reformatting?
If so you're getting into high-end array controllers. Any decent RAID
controller these days supports hot-plug and hot-swap, however if you
intend to use IDE drives then you should consider SATA, which has this
capability built in. But from what you're describing I suspect you're
going to end up using SCSI.
The ability to handle simultaneous reads and writes from multiple
workstations is another storage configuration issue.
Any contemporary network operating system presents its volumes as
lettered drives on DOS and Windows boxen. That's a non-issue.
