11 RESTful API SAN Service

The RESTful API SAN service lets you connect Oracle ZFS Storage Appliance to your Storage Area Network (SAN).

SAN Overview

A SAN has the following basic components:

• A client that accesses network storage

• An Oracle ZFS Storage Appliance system that provides network storage

• A network that links the client to the storage

These three components remain the same regardless of which protocol is used on the network. In some cases, the network might even be a cable between the initiator and the target, but in most cases some type of switching is involved. The RESTful API SAN service manages four types of SAN resources for each supported protocol:

• Initiators – An application or production system end-point that is capable of initiating a SCSI session and sending SCSI commands and I/O requests. Initiators are also identified by unique addressing methods.

• Initiator groups – A set of initiators. When an initiator group is associated with a Logical Unit Numbers (LUNs), only initiators from that group can access the LUN.

• Targets – A storage system end-point that provides a service of processing SCSI commands and I/O requests from an initiator. A target is created by the storage system administrator, and is identified by unique addressing methods. A target, once configured, consists of zero or more logical units.

• Target groups – A set of targets. LUNs are exported over all the targets in one specific target group.
