IP Network The IP network is the infrastructure used to transfer data between the iSCSI initiator and the HP SR2122. SR2122 iSCSI router The HP SR2122 iSCSI Router is the bridge between the iSCSI Initiators and the SAN storage that converts IP to FC protocol and provides iSCSI Initiator access to FC storage. SCSI routing provides IP hosts with access to FC storage devices as if the storage devices were directly attached to the hosts, with access to devices being managed primarily in the Storage Router. An iSCSI target (also called logical target) is an arbitrary name for a group of physical storage devices. The iSCSI targets are created and mapped to physical storage devices attached to the Storage Router. The Storage Router presents the iSCSI targets to IP hosts (iSCSI initiators) as if the physical storage devices were directly attached to the hosts. With SCSI routing, storage devices are not aware of each IP host; the storage devices are aware of the Storage Router and respond to it as if it were one FC host. You can configure storage routers in a cluster to allow the storage routers to back each other up in case of failure. A storage router cluster consists of two to four storage routers connected as follows: ¦ Connected to the same hosts ¦ Connected to the same storage systems ¦ Connected to each other through their management and high availability (HA) interfaces In a cluster, storage routers continually exchange HA information to propagate configuration data to each other and to detect failures in the cluster. The storage routers exchange HA information through two separate networks: one connected to the management interface of each Storage Router and the other connected to the HA interface of each Storage Router. To make sure that HA information is exchanged reliably between storage routers, the storage routers balance the transmission of HA information between the management and the HA interfaces. SR2122 access is controlled through an access list and a VLAN identifier (VID) number of the hosts. An access list enables access to storage devices attached to the Storage Router with any combination of host IP address(es), CHAP user name(s), or iSCSI name(s). An access list contains these combinations. Host VID enables access to storage devices according to the VID of each host. You can use a combination of access lists and VIDs to configure access in the Storage Router; that is, you can specify that certain hosts according to IP address in a VLAN can access storage devices attached to the Storage Router. iSCSI SR2122 Storage Router: Getting Started Guide iSCSI in a Heterogeneous SAN Fibre Channel SAN A Storage Area Network is a dedicated, centrally managed, secure information infrastructure, which enables any-to-any interconnection of servers and storage. SANs are built to incorporate the best of both storage and networking interfaces: fast and efficient communications optimized for movement of large amounts of data, but with access to a wide range of other servers and storage devices on the network. The SR2122 iSCSI Router is supported on any currently supported HP B-Series, C-Series, or M-Series switch fabric. For the latest HP switch topoligies and fabric rules, please read the “HP StorageWorks SAN Design Reference Guide” avalable at: SAN Storage The SR2122 supports the RA/MA8000, ESA/EMA12000, MSA1000, EVA, VA and XP storage arrays.
