Introduction 1 Chapter Overview This chapter contains information on the following: ■ Operation Indicators on page 18 ■ Processing SCSI Information on page 20 ■ HP Surestore Bridge Features on page 22 ■ HP Surestore Bridge Benefits on page 24 ■ Fibre Bridge Components and Supported Products on page 25 ■ Choosing a Location on page 28 ■ Fibre Channel Configurations on page 29 The HP Surestore FC 2/1 LV and 4/1 HV bridges provide connectivity between a Fibre Channel (FC) point-to-point (PPP), Fibre Channel switched fabric (FC-SW) or Fibre Channel arbitrated loop (FC-AL) and two LVD Ultra-2 SCSI buses on the 2/1 LV, and four HVD Narrow/Wide Fast/Ultra SCSI buses on the 4/1 HV. The bridge is a storage router that translates the Fibre Channel protocol (FCP) to and from the SCSI protocol so that Fibre Channel and SCSI devices can communicate with each other. It attaches to a Fibre Channel host or switch and transfers the command, data, and status information to SCSI targets. Packets are transferred transparently by the bridge from host to targets and vice versa. Chapter Overview 15

■

The HP Surestore FC 2/1 LV and 4/1 HV bridges provide connectivity
between a Fibre Channel (FC) point-to-point (PPP), Fibre Channel switched
fabric (FC-SW) or Fibre Channel arbitrated loop (FC-AL) and two LVD Ultra-2
SCSI buses on the 2/1 LV, and four HVD Narrow/Wide Fast/Ultra SCSI buses
on the 4/1 HV.
The bridge is a storage router that translates the Fibre Channel protocol (FCP)
to and from the SCSI protocol so that Fibre Channel and SCSI devices can
communicate with each other. It attaches to a Fibre Channel host or switch and
transfers the command, data, and status information to SCSI targets. Packets
are transferred transparently by the bridge from host to targets and vice versa.
