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)

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).

Web-Based Enterprise Management (WBEM)

• a set of management and Internet standard
  technologies developed to unify the management of
  enterprise computing environments.
• The Common Information Model (CIM) specification
  is the language and methodology for describing
  management data.

Storage Network Projects Based on Input from
Sarah Jelinek

• SAN Management
• Automated discovery, backup/disaster recovery,
  capacity planning, fault management
  (detection/isolation), hierarchical storage
  management.
• 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
