The host-base storage portion of the Storage Management Technical Specification defines management profiles for autonomous, component and abstract profiles for management of host-based storage devices. The autonomous profiles describe the management of a stand-alone host-based storage entity. The component profiles describe management of aspects of host-based storage entities that may be used by other autonomous profiles. Finally, this section describes abstract profiles that may be used as a basis for creating additional Host-based autonomous profiles.

This version of the Host-based Storage portion of the Storage Management Technical Specification includes autonomous profiles:

  • The Host Discovered Resources Profile

    This profile defines the model for the storage devices presented to an operating system running on a host computer system. In addition, this profile describes the map of storage associated to a host-computer system that a client application can discover.

  • “The Fibre Channel HBA Profile

    This profile defines the model and functions of a Fibre Channel HBA that exports block storage to a host computer system from a SAN device (Fibre Channel switch, array, tape library, etc.).

  • iSCSI Initiator Profile

This profile defines the model and functions necessary to manage an iSCSI initiator.

Component profiles used by autonomous profiles to describe aspects of host-based storage elements and services. The component profiles defined in this version of the specification include:

  • Host Hardware RAID Controller Profile

    This profile defines the model and functions of a host-based RAID controller that exports block storage to a host computer system from locally attached storage devices (internal hard drives, JBODs, etc.)

  • Storage HBA Profile

    This profile defines the model and functions of a SAS, SATA, SPI, or Fibre Channel HBA that exports storage to a host computer system from a SAN device (Fibre Channel switch, array, tape library, etc.).

  • Disk Partition Profile

    The Disk Partition profile models partition (or slice) configuration services provided by operating systems on some platforms.

  • SB Multipath Management Profile

    The SB Multipath Management Profile models paths (connections between host controllers and device ports) for environments supporting the SB (Single Byte) command protocol.

  • SCSI Multipath Management Profile

The SCSI Multipath Management profile models paths (connections between host controllers, device ports, and logical units) for environments supporting the SCSI command protocol.
