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.
• DTMF’s WBEM web page

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
