5. storage networkchow5 Storage Interconnect Fibre Channel is used to move SCSI data/command from Servers to disk arrays and tape drive. Very expensive dedicated fibre lines. Distance limitation---10km? New prosposals to carry SCSI over IP networks: –iSCSI –Fibre Channel over IP (FCIP) –Internet Fibre Channel Protocol (iFCP)

6. storage networkchow6 Differences in iSCSI, FCIP, iFCP iSCSI: wraps SCSI data/commands in TCP/IP packets. Given full access IP management and routing. –Wireless retail, use Cisco/Nishan? Switch –Too slow  use TOE(TCP offload Engine, by intel, adaptec,..). –IBM stop 200i iSCSI targe storage appliance development. FCIP: move encapsulated Fibre channel data through “dumb” IP tunnels, which connect SANs. Cannot take advantage of routing and IP management features. –EMC, CNT, Pirus, SANcastle, SAN valley. iFCP: wrap Fibre Channel data in IP packets but maps IP address to individual Fibre Channel devices. More stable? Allow routing and IP management. –Carlson uses Nishan multiprotocol switch (sole provider of iFCP).

The Common Information Model (CIM) specification is the language and methodology for describing management data.

Policy management and associated QOS SAN Security –Hard zoning, virus?, access control, truested manager. Intelligent Storage Switch (load balancing?, preferred treatment) WBEM/CIM Projects –Building a distributed CIM object manager (CIMOM) –http://sourceforge.net/projects/wbemsource/ for WBEM open source projects. –Embeded WBEM/CIM infrastructure
