Copying Files to SAN is SLOOOW

I have problem that my NOC cann't fix and I'm not capable of solving this
issue. I'm a programmer that know a 'little' about networking. We have 8
leased managed servers (SuperMicro boxes, 64bit Windows 2003 Ent Server, 2
gig of RAM, 2 disk -RAID 1 config) that we host web site on. We pay about
$100 a month for 100 GB access to an APPLE SAN. Now we don't have an HBA so
in order to use the SAN we have to log into the box map a drive and copy the
file over. So annoying. The box has 2 Gig NIC cards. One for public interface
and one for private.

The mapped san drive is mapped through the private interface - when I copy
a file from any of our server to the SAN it is painfully slow. A 100 MB
files take 45 minutes to copy. NIC traffic on our private interface is
always less than 1%.

I take a file that is alraedy on the SAN and copy it back to the server and
it flies. The NIC utilization spikes right up and its done in like 10
seconds.

With my little developer brain I did a tracert to the SAN - one hop directly
to the SAN IP less than 1ms. I look at route print and all looks ok - there
is no obvious route using the wrong interface.

My NOC that I pay cannot figure this out - anyone have any idea what could
be causing this problem?!
