Features
HP SureStore E hubs provide the following features:
•Short-wave hub (model S10): 10 non-Open Fibre Control (non-OFC) short-wave optical transceivers
•Long-wave hub (model L10): nine non-OFC, short-wave optical transceivers and one non-OFC, long-wave optical transceiver
•Local retime and regeneration of transmit signals to prevent accumulation of jitter and improve the signal
•Reliable, automatic bypass of failed nodes; dynamic recognition of newly added or removed nodes, with a controller in each port permitting the bypass of a port if the port fails signal validity tests
•Active loop reconfiguration when a node to an arbitrated loop is added, removed, or moved
•Plug-and-play capability, which allows the hub to connect to compatible servers and other Fibre Channel Arbitrated Loop (FC-AL) devices while they are operating ( FC-AL devices can be added or removed while the hub is active.)
•Cascade support (hub-to-hub connections) for increased loop distances
Cascaded short-wave hubs are supported up to 500 meters; cascaded long-wave hubs are supported up to 3000 meters (3 km). Under certain conditions, cascaded long-wave hubs are supported up to 10,000 meters (10 km) (see page 105 for more information). The 10-km capability only applies to long-wave hubs connected to HP-UX servers.
Note Increased loop distances are associated with increased latency times.
•Access to the RS-232 interface for firmware upgrades and hub configuration and troubleshooting
•Support for a hub management tool (Fibre Channel Manager) to remotely manage and monitor the health of the hub
