This part of ISO/IEC 24775 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 (or subprofiles) 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 part of ISO/IEC 24775 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 hostcomputer 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 Subprofile 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 (subprofiles) defined in this version of the standard 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 Subprofile The Disk Partition profile models partition (or slice) configuration services provided by operating systems on some platforms. • SB Multipath Management Subprofile The SB Multipath Management Subprofile models paths (connections between host controllers and device ports) for environments supporting the SB (Single Byte) command protocol. • SCSI Multipath Management Subprofile The SCSI Multipath Management profile models paths (connections between host controllers, device ports, and logical units) for environments supporting the SCSI command protocol.
