we have vspher 4 with EqalLogic ISCSI SAN
Veeam is installed on a physical Win 2008 and directly connected to the SAN network using ISASI initiator with 1 Gb NIC
1Gb Network, Jumboframes 9000 and flow control are all enabled al the way through
I setup a backup job to backup file to the same VeeaM server but the
Process rate = 52 MB/s
I thought i would see something near 1Gb. this is almost the same if we backup through the network and not use the Direct SAN
is this throughput normal?

Having 1 Gb NIC connection doesn't actually mean that you will automatically get 1Gb processing rate on the full run.
First of all could you please clarify what is the CPU usage on the backup server while you run the backup job? On top of that, please take a look at the corresponding F.A.Q. section, where there are tips on improving iSCSI network throughtput written by joergr (our iSCSI guru).

By the way, you seem to assume that this processing rate you see in UI is the same thing as data copy througtput over your iSCSI network - but it is not. The latter will always be faster. Processing rate is affected by other operations like guest processing or snapshot management (calculated as total VM size divided by total VM processing time). If you want to measure your real SAN access throughtput, use Windows Task Manager network monitor for iSCSI NIC instead.
Also, in future, kindly please review FAQ and search forum before posting your question.
