Fabric
For redundancy, InfiniBand Host Channel Adapters (HCAs) can be dual-connected to a redundant pair
of Topspin 270/Cisco SFS 7008s.
In an InfiniBand fabric that includes more than one Topspin 270/Cisco SFS 7008: if the subnet manager
on the Topspin 270/Cisco SFS 7008 that is acting as the master fails, another subnet manager will take
over within seconds. All necessary state information is kept in sync.
Non-Blocking Architecture
The Topspin 270/Cisco SFS 7008 provides non-blocking switch element architecture with full
