From the computer perspective, SCSI LUN is only a part of the full SCSI address. The full device's address is made from the: c-part: controller ID of the host bus adapter, t-part: target ID identifying the SCSI target on that controller, d-part: disk ID identifying a LUN on that target, s-part: slice ID identifying a specific partition on that ...
OpenSSI is an open-source single-system image clustering system. It allows a collection of computers to be treated as one large system, allowing applications running on any one machine access to the resources of all the machines in the cluster.
In computing the SCSI RDMA Protocol (SRP) is a protocol that allows one computer to access SCSI devices attached to another computer via remote direct memory access (RDMA). [1] [2] The SRP protocol is also known as the SCSI Remote Protocol. The use of RDMA makes higher throughput and lower latency possible than what is generally available ...
The Linux-IO Target (LIO) is an open-source Small Computer System Interface (SCSI) target implementation included with the Linux kernel. [ 1 ] [ better source needed ] Unlike initiators, which begin sessions, LIO functions as a target, presenting one or more Logical Unit Numbers (LUNs) to a SCSI initiator , receiving SCSI commands, and managing ...
SCSI was introduced in the 1980s and has seen widespread use on servers and high-end workstations, with new SCSI standards being published as recently as SAS-4 in 2017. The SCSI standards define commands, protocols, electrical, optical and logical interfaces. The SCSI standard defines command sets for specific peripheral device types; the ...
As in a client–server architecture, an initiator is analogous to the client, and a target is analogous to the server. Each SCSI address (each identifier on a SCSI bus) displays behavior of initiator, target, or (rarely) both at the same time. There is nothing in the SCSI protocol that prevents an initiator from acting as a target or vice versa.
RIP (Real IP address): the IP address used to connect to the cluster nodes; DIP (Directors IP address): the IP address used by the director to connect to network of real IP addresses; CIP (Client IP address): the IP address assigned to a client computer, that it uses as the source IP address for requests being sent to the cluster
The client is called a SCSI initiator and the server is called a SCSI target. A SCSI domain consists of at least one SCSI device, at least one SCSI target and at least one SCSI initiator interconnected by a service delivery subsystem. A SCSI device has one or more SCSI ports, and a SCSI port may have an optional SCSI port identifier (SCSI ID or ...
