IBM SAN40B-4 SAN Fabric Switch

IBM SAN40B-4 SAN Fabric Switch

The IBM SAN40B-4 SAN Fabric Switch provides redundant, hot-swappable, loadsharing power supply/fan modules that are designed to allow the switch to remain online if one module fails. Dual power cords allow attachment to separate sources to help improve availability. Hot-pluggable optical transceivers are designed to be replaced without taking the switch offline. Availability of many non-disruptive firmware upgrades helps minimize disruption.

The IBM SAN40B-4 SAN Fabric Switch provides 40, 32, or 24 active ports. It is designed for high performance with 8 Gbps link speeds and backwards compatibility to support links running at 4, 2, and 1 Gbps link speeds depending on the speed of the device on the other end of the link. Up to 1,280 Gbps throughput is possible with an 80-port configuration. E_Port connectivity is standard to support links to other SAN switches, directors and routers via Inter-Switch Links (ISLs). Up to 8 Gbps throughput at extended distances of up to 100 km is possible with the Extended Fabric Activation feature and appropriate distance extension technology.

The IBM SAN40B-4 SAN Fabric Switch has the 8-Port Activation feature and is designed to support scalable switch upgrades. This feature provides an activation key to enable eight additional ports while helping avoid fabric disruption. One or two of these features can be used to upgrade a base switch to 32 or 40 active ports. Optical transceivers are required for all active ports. Midrange and enterprise SAN users require high-availability switch fabric solutions.
