Slow file transfers

[JonMoore87]

Hi there,

I have a DSS v6 with 1 LUN running as an iSCSI target, it's being used to store Hyper-V virtual machines.
When I copy a large file (say 25GB) to the sever that is stored on the SAN I get speeds of around 5MB/s the SAN has a 1Gb network card and the iSCSI network is dedicated.
Is there a way to improve this?

Thanks,
Jon

how much ram is in your server?
more ram may help
try these settings from the console

maxRecvDataSegmentLen=262144
MaxBurstLength=16776192
Maxxmitdatasegment=262144
maxoutstandingr2t=8
InitialR2T=No
ImmediateData=yes

Thanks Symm,

I'll try that on monday when I have access to the console. In the mean time; I've found that the copy speed seems fine in short burts like 4 to 6 GB, migrating a VM to the SAN first 5GB really quick, then about a 5 minute gap, then another 5GB... this tends to cause transfers to time out. I've got 4GB of RAM.

Cheers,
Jon

I've raised a support ticket this morning, not had a response yet... hopefully open-e will come up with something, no one else had this issue?
