Information technology — Storage management — Part 7: Host elements (Adopted ISO/IEC 24775-7:2021, second edition, 2021-03)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT),
Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC.
For brevity, this Standard will be referred to as CSA ISO/IEC 24775-7 throughout.
This Standard replaces CAN/CSA-ISO/IEC 24775:12 (adopted ISO/IEC 24775:2011).
The International Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
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.
