Cheetah 9LP FC General Description
CheetahTM 9LP FC drives are random access storage devices designed to support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Protocol. ST39102FC drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.
You can view the Fibre Channel interface as a transport vehicle for the supported command set (ST39102FC drives use the SCSI command set). In fact, the Fibre Channel interface is unaware of the content or meaning of the information being transported. It simply packs the SCSI commands in frames, transports them to the appropriate devices, and provides error checking to ensure that the information reaches its destination accurately
Cheetah 9LP FC drives have the following standard features:
- Integrated dual port FC-AL controller
- Concurrent dual port transfers
- Support for FC arbitrated loop and private and public loop attachment
- Differential copper FC drivers and receivers
- Downloadable firmware using the FC-AL interface
- Drive selection ID and configuration options are set on the FC-AL backpanel or through interface commands. Jumpers are not used on the drive
- Fibre Channel worldwide name uniquely identifies the drive and each port
- User-selectable logical block size (512 to 4,096 bytes per logical block)
- Selectable frame sizes from 128 to 2,112 bytes
- Industry standard 3.5-inch low profile form factor dimensions
- Programmable logical block reallocation scheme
- Flawed logical block reallocation at format time
