Memory resource provisioning using SAS zoning

摘要

An example method for memory resource provisioning using SAS zoning can include a serial attached Small Computer System Interface (SCSI) (SAS) switch and a provisioning manager (PM) executing on the SAS switch. A plurality of servers are communicatively coupled to the SAS switch, each server executing an operating system (OS) having access to one or more OS volumes. A host provisioning agent (HPA) executes on the OS of each of the plurality of servers. A plurality of memory resources are communicatively coupled to the SAS switch. Each memory resource can have a number of physical hard drives. A first portion of the memory resources is associated with zone groups corresponding to the plurality of servers. A second portion of the memory resources is associated with a provisioning zone group (PZG) hidden from the plurality of servers but available to the PM.

1. A system for memory resource provisioning using serial attached Small Computer System Interface (SCSI) zoning, comprising:
a Serial Attached SCSI (SAS) switch, the SAS switch communicatively coupled to a storage administrator executing a provisioning manager (PM); a plurality of servers communicatively coupled to the SAS switch, each server executing:
an operating system (OS) having access to one or more OS volumes;a host provisioning agent (HPA) on top of the OS; and a plurality of memory resources communicatively coupled to the SAS switch, each memory resource having a number of physical hard drives, wherein:
a first portion of the memory resources is associated with zone groups corresponding to the plurality of servers and a second portion of the memory resources is associated with a provisioning zone group (PZG) hidden from the plurality of servers but available to the PM for allocation to the zone groups responsive to an HPA request;a quantity of physical hard drives allocated to a zone group corresponding to a server among the plurality of servers is based on information about an OS volume among the one or more OS volumes exceeding a pre-defined threshold and configuration information of an array controlled by the server's array controller;the configuration information of the array includes RAID level, physical drive size, physical drive type, and physical drive speed; andthe allocated physical hard drives are compatible with the array controlled by the server's array controller.
