SAN SRP Configuration

SCSI RDMA Protocol (SRP) is a protocol supported by Oracle ZFS Storage Appliance for sharing SCSI-based storage over a network that provides RDMA services (that is, InfiniBand).

SRP ports are shared with other IB port services, such as IPoIB and RDMA. The SRP service may only operate in target mode. SRP targets have the following configurable properties.

Table 2-27 SRP Target Properties

Property	Description
Target EUI	The Extended Unique Identifier (EUI) for this target. The EUI is automatically assigned by the system and is equal to the HCA GUID over which the SRP port service is running.
Alias	A human-readable nickname for this target.

In addition to those properties, the BUI indicates whether a target is online or offline:

On clustered platforms, peer targets should be configured into the same target group for highly available (multipathed) configurations. SRP multipathed I/O is an initiator-side configuration option.

SRP initiators have the following configurable properties.

Property	Description
Initiator EUI	The EUI for this initiator
Alias	A human-readable nickname for this initiator

SRP performance can be observed via Analytics, whereby one can break down operations or throughput by initiator or target.
