Network performance optimization
When you are setting up the network, there are some items to consider that can improve network performance.
Consider these items when you set up the network:
- LAN-free backup
- LAN-free backup can reduce the load on the network and on the Tivoli® Storage Manager server, thus improving data transfer rates. When you use LAN-free backup, ensure that Fibre Channel adapter capacity to the SAN can accommodate the data transfer rates of the disk reads and tape writes.
- Network bandwidth
- In general, the effective throughput capacity is approximately half of the theoretical network bandwidth. For high-speed networks such as Gigabit Ethernet LAN, the network adapters limit the throughput rather than the network itself.
- Network topology
- A dedicated backbone network that is used only for backup and restore operations can improve the data transfer rate.
- TCP options
- Use TCP options that are the most beneficial for your environment.
- Multiple Paths
- Increase the overall throughput rate to the backup server by providing a way to specify multiple network paths.
