Operating in Gigabit Ethernet Environments
Best Practices for IP SANs
IP SANs should be based on Gigabit Ethernet 1000BaseT network topography. Since
backups and storage networks create a good deal of traffic, a dedicated subnet should
be utilized. IP SANs should not be sharing bandwidth with regular user LAN traffic.

Best Practices for iSCSI
The best performance with iSCSI is achieved by setting the iSCSI parameters to the
following state:
following state:
• R2T = No
• Immediate Data = Yes or No
The parameters below can be set to the maximum values listed below:
• First Burst Length = 128K
• Maximum Burst Length = 256K
• Maximum Receive Buffer Length = 64K
Best performance is achieved by setting these values to their maximum value.
