Tuning network performance
If possible, use a dedicated local area network
(LAN) or a storage area network (SAN) for backup operations. Keep
device drivers for network components updated to take advantage of
the latest fixes and improvements. Consider the IBM Spectrum Protect™ options
that can help you tune how the clients and the server use the network.
Ensure that you understand how TCP/IP works and review the information
about TCP flow control and the sliding window.
