Features

The zfcp device driver supports a wide range of SCSI devices, various hardware adapters, specific topologies, and specific features that depend on the Z hardware.

  • Linux on Z can use various SAN-attached SCSI device types, including SCSI disks, tapes, CD-ROMs, and DVDs. For a list of supported SCSI devices, see 
    www.ibm.com/systems/z/connectivity
  • SAN access through the following hardware adapters:
    • FICON® Express16S+ (as of z14)
    • FICON Express16S (as of z13®)
    • FICON Express8S
    • FICON Express8
    • FICON Express4
    You can order hardware adapters as features for mainframe systems.

    See Fibre Channel Protocol for Linux and z/VM® on IBM® System z®, SG24-7266 for more details about using FCP with Linux on Z.

  • The zfcp device driver supports switched fabric and point-to-point topologies.
  • As of zEnterprise®, the zfcp device driver supports end-to-end data consistency checking.
  • As of FICON Express8S, the zfcp device driver supports the data router hardware feature to improve performance by reducing the path length.
