how to increase through put of LAN to 1GB

[Muhammad Yousuf Khan <sirtcp@gmail.com>]

i am using Debian with below specs
1 GB RAM
 Xeon 2.8
2 TB SATA x2 (RAID 1)

i learn that my LAN throughput is like 200 to 300 Mbps which is quite
enough for me for now. but i am planning ahead to use ISCSI for
virtualization to provide HA, therefore i need my Giga LAN to reach
the 1000 Mbps throughput.

so i need to know. what could be done to achieve this ?


Thanks,
