The addition of iSER adds no interfaces to the existing PSARC case. The release binding is minor. If anyone disagrees with this being closed approved automatic, I'll set the timer. - John Template Version: @(#)sac_nextcase %I% %G% SMI This information is Copyright 2008 Sun Microsystems 1. Introduction 1.1. Project/Component Working Name: iSCSI Port Provider for COMSTAR 1.2. Name of Document Author/Supplier: Author: Peter Dunlap 1.3 Date of This Document: 16 September, 2008 4. Technical Description Background ---------- The COMSTAR (Common Multiprotocol SCSI target PSARC 2007/523) project introduced a modular SCSI target framework to Solaris. COMSTAR allows a Solaris system to act as a block storage SCSI device, analagous to a disk array. Currently COMSTAR supports only Fibre Channel transport. In COMSTAR terminology, a transport plug-in is called a "port provider". PSARC 2008/395 iSER: iSCSI Extensions for RDMA describes a project to develop an iSER initiator and iSER target implementation and was approved on 7/9/2008. The iSER initiator will be based on the existing iSCSI initiator modified for iSER transport. In addition, the project delivers an iSCSI port provider to COMSTAR and the iSER target will consist of that iSCSI port provider combination with an iSER transport module. The iSCSI port provider is useful by itself (without iSER) to provide iSCSI transport access to COMSTAR logical units. _________ ___________ | | | | +->| libstmf | | libiscsit |<-+ | |_________| |___________| | | | | User Space | ----|---------------------------------------------------|---- | Kernel Space | | ______________ | | | | | | | "sbd" | | | | block/disk | | | | LU Provider | | | |______________| | | | | ------- LU Provider Interface ------- | | ______________ | | | | | +----------------->| STMF | | |______________| | | ------ Port Provider Interface ------ | ______________ ______________ | | | | | | | "fct" | | "iscsit" | | | FC Port | | iSCSI Port |<--------+ | Provider | | Provider | |______________| |______________| Proposal -------- The project team would like to deliver PSARC 2008/395 in multiple phases.
