7.9. Gadzoox Bitstrip TW Fibre Channel Hub
The Gadzoox Bitstrip™ TW Fibre Channel Hub will not be included in the Escala offering as of
31/01/2001.
7.9.1. Highlights
The Gadzoox Bitstrip™ TW Fibre Channel Arbitrated Loop (FC-AL) hub is specifically designed to
be a cost effective entry point into high availability, gigabit storage networking. The Bitstrip TW
incorporates several active features, such as Gadzoox’ Reflex intelligent port bypass and per port data
regeneration, which ensure reliable, trouble free, plug and play operation as well as a high degree of
data integrity.
The Bitstrip TW is a 9-port FC-AL active hub that uses a DB-9 connector for each port allowing
native connection to copper cabling. The Bitstrip TW also supports optics on all 9 ports through the
use of external DB-9 to optics Media Interface Adapters (MIAs). MIAs are hot-plug and field
upgradable, providing hub users with maximum flexibility in mixing copper and optical connections in
their Fibre Channel systems. Power is automatically supplied on a per port basis to each connected
MIA.
The Reflex feature, an intelligent port detection and bypass capability, dynamically reconfigures the
arbitrated loop network to preserve communication between all operating devices. Using Reflex, the
Bitstrip TW manages movement of nodes on and off the network, constantly monitoring nodes for
failure, cable disconnection or network reconfiguration. Non-operating nodes are automatically
bypassed, newly communicating nodes are automatically entered onto the loop. All loop
reconfiguration is handled by the Bitstrip TW without disrupting communication on the remainder of
the network. In the absence of the Bitstrip TW, the physical loop would need to be recabled on the
addition or removal of a node, bringing the network down and disrupting communications.
