About Fibre Transport throughput
The slowest speed of the following components may limit the Fibre Transport throughput rate:
The speed capability of the SAN client.
The speed with which the client reads and writes to the file system or database affects performance).
The read and write speed of the storage unit.
The bandwidth of the computer PCI I/O memory.
On the SAN clients, a non-PCI-X card on the PCI-X bus of the HBA reduces the speed of the controlling bus. NetBackup FT performance may not be affected as much as on a media server, but performance may degrade to unacceptable levels.
The speed of the Fibre Channel pipe that transports the data.
The topology of the Fibre Channel.
Bottlenecks may occur when multiple data streams are sent through a shared element such as a trunk or an inter-switch link.
