Iomega StorCenter ix4-200d iSCSI performance

Question

Hi there, just looking for some help here, we have an Iomega StorCenter ix4-200d device that was not in use and I tried to make a drive for storing media files and moving them from the file server. I have created an iSCSI disk and connected to a Windows 2008R2 using an iSCSI Initiator, the Iomega box comes with two network interfaces that were previously bonded, the connection was quick and easy to setup, the problem that I am having is performance. When transferring small file/s the transfer is quick and effective, but if the file/s pass more than 1GB windows explorer crashes and the OS get frozen, I have been monitoring the disk use and is horribly high when transferring those files, taking more than 10min for a 1.5GB to transfer, the LAN is 1GB speed. I read about creating specific VLANS only for iSCSI transfers, but we did not have that before and the drive was previously used as iSCSI backup solution, before another solution now in place replaced it Any help or thoughts are more than welcome Juan

GUS_Lenovo, Really helpful your coment, please can someone else let us know if it is having this problem. The setup is very simple a VMware ESXi 5.5 virtual machine, OS 2008R2, connected using passtrough native windows iSCSI initiator to an external Iomega StorCenter ix4-200d drive. I disconnected the target from the troubled server and connected the iSCSI disk to a test server, same setup VMware 2008R2 connected to the pysical iSCSI uing the windows native initiator, no roles on it. I double checked that only the test server was connected into it, same symptom, transfers files up to 500MB are quick and effective, if the file/s to transfer pass 1GB or more the transfer halts and the explorer process on the VM crashes, not very effective for now. Bandwith?? any help very much appreciated
