Chapter 1 Product Overview
System Features
Scalability
The embedded subnet manager running on the Cisco SFS 7000P and SFS 7000D Server Switches can manage up to 1,152 hosts.
High Availability
High availability operates at the hardware, port, and fabric level. These features are described below.
Hardware
High availability at the hardware level means that the Cisco SFS 7000P and SFS 7000D Server Switches feature
Ports
High availability is supported at the ports level such that if any single InfiniBand port fails, none of the other ports have interrupted service.
Fabric
High availability is supported at the fabric level as well. For redundancy, InfiniBand HCAs can be
When an InfiniBand fabric includes more than one Cisco SFS 7000P Server Switch or
Cisco SFS 7000D Server Switch, and the subnet manager fails on the Cisco SFS 7000P Server Switch or the Cisco SFS 7000D Server Switch that is acting as the master, another subnet manager takes over within seconds. (See Figure
