iSCSI SR2122 storage router
Third Edition (September 2003)
Part Number: AA-RTE1C-TE
This document describes the integration of IP-based Storage Networks using the iSCSI protocol to HP
StorageWorks Fibre Channel SANs and HP Storage arrays. The HP SR2122 iSCSI Router is used to bridge from
TCP/IP hosts to Fibre Channel storage.

About this Document iSCSI Protocol The SCSI transport protocol iSCSI maps block-oriented (CDB) storage data over TCP/IP networks (through iSCSI PDUs). The iSCSI protocol enables universal access to storage devices and storage-area networks (SANs) over standard Ethernet-based TCP/IP networks. These networks may be dedicated networks or may be shared with traditional Ethernet applications. IP LAN/WAN routers and switches can be used to extend the IP storage network to the wide area of applica

iSCSI in a Heterogeneous SAN iSCSI in a Heterogeneous SAN Although the iSCSI protocol is written as a complete data transport from host to storage this chapter will only discuss the current HP supported topology of iSCSI hosts to Fibre Channel storage using the HP SR2122 iSCSI Router. For further details please read “HP StorageWorks iSCSI storage router 2122 User Guide PN: 304835-002” Section 4 -SCSI Routing Overview. Typical Network Structure The addition of iSCSI to the SAN means that two

iSCSI in a Heterogeneous SAN iSCSI Initiator The IP host, or iSCSI Initiator uses the iSCSI Driver to enable target resource recognition & attachment to the SR2122 over IP. The iSCSI driver is configured with the Gigabit Ethernet IP address of each SCSI routing instance running on the SR2122 with which the host is to transport SCSI requests and responses. The iSCSI initiator sees the storage resources (LUNs) as if they were just local drives attached directly to the server. On the SR 2122, I

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 a

After physically connecting the FC port(s), and if zoning is enabled, it is recommended to create a new zone that includes the FC Port WWPNs and the WWPNs of the storage arrays that will be serving storage to the SR2122.

Serving Fibre Channel Storage to the SR2122 Serving Fibre Channel Storage to the SR2122 Once the SR2122 is properly configured, connected and zoned within the SAN, the next step is to present storage to the router. Where normally the storage is presented to a server, we must first get the FC storage to the SR2122, then we have to present that storage to the iSCSI Initiators over IP. As previously mentioned, the SR2122 FC ports look like a typical Fibre Channel Host Bus Adapter to the storage
