Network Upgrade Project

• Called Integrated Technology Partnership
• Board of Trustees have approved the project
• Public announcements by Sprint and Cisco
• Articles appeared in the New York Times and in
  various trade publications
• Final contract negotiations with Sprint are under
  way and expected to be completed in April
• Web site available to show project status
• http//cnsstats.cwru.edu/net/upgrade/index.html

Network Upgrade Project

• Additional areas of interest are being explored
• Telephony
• Internet access
• Process
• Weekly project meeting between CWRU and
  Sprint/Cisco
• Affected building/department representatives are
  being invited
• Identify potential problems
• Work out an installation schedule for a given
  building
• Working with Plant Services to make the necessary
  facilities changes to accommodate the new
  equipment

6
Network Upgrade Project

• Currently using a mini-switch?
• 24 ports of 100 mb/s Ethernet in each SER
• Use a new mini-switch with a gigabit Ethernet
  uplink
• Example Netgear FS509 (has fiber uplink) (street
  price of 620)
• Example Netgear FS509T (requires media converter)
  (street price of 240)
• Printers
• 24 ports of 100 mb/s Ethernet in each SER
• Use mini-switch (see above)
• Laptops
• Use wireless (as many as 1000 access points to be
  deployed)
• Use mini-switch (see above)
• 24 ports of 100 mb/s Ethernet in each SER
• New Mac laptops have 10/100/1000 copper Ethernet
  NICs
• No PCMCIA adapters available at a gigabit yet

VPN Changes

• Changing VPN server systems
• Moving from Cisco 5000 to Cisco 3000 series
• VPN client changes
• Support for native (built-in) Windows (98 thru
  XP) VPN client
• Clients exist for Mac, Unix
• Clients exist for PDAs (which are not supported
  on the 5000)
• Current VPN 5000 clients are NOT compatible with
  3000 series
• Transition will start sometime in March
• Will use new VPN host address
• Like the Cisco 5000, the Cisco 3000 system will
  be used both for wireless and off-campus

E-mail and Calendaring

• E-mail
• iPlanet Messenger
• IMAP4 and POP3
• LDAP provisioned
• Calendar
• Steltor Corporate Time
• Two phases Faculty/staff this year, students
  next year
• LDAP provisioned
• LDAP/Directory
• iPlanet Directory
• Will be base for future account management and
  service provisioning
• Servers being acquired (Sun)
• SAN and NAS for file storage
• Availability over the summer

9
Network Storage

• SAN (Storage Area Network)
• Disk array
• Integrated control and management hardware
• Block access to disk
• Interface choices Fiber Channel, iSCSI
• Host adapter interface
• NAS (Network Area Storage)
• Disk array
• Integrated control and management hardware
• File system level access to disk (NFS, CIFS,
  others)
• Ethernet interface
• NAS Head/Gateway
• NAS using a SAN backend (in place of disk array)

10
Network Storage

• Benefits compared to direct access storage
• No pockets of unusable storage
• Highly reliable
• Multiple RAID choices
• Redundant hardware
• Highly scalable
• Hot swap of drives
• Add storage to applications on the fly
• Increased functionality
• Snapshots (instant copies of files)
• Full copy done in background
• Maintenance and operations functions performed
  live without taking down servers using the storage

11
Network Storage

• Will develop jumbo frame VLAN for server access
  to storage
• Increase MTU to 9192 bytes (versus 1500)
• Port level access to VLAN
• Specialized host adapters can be used to improve
  efficiency
• TCP/IP Offload Engine (TOE) based adapter
• Storage can be scaled to hundreds of terabytes
• Tape subsystem for archival and disaster recovery
• Initial implementation concurrent with new e-mail
  system

Streaming Video

• Video conferencing (H.323)
• Digital streamed CATV
• Replace current analog system
• Streamed video (stored or live)
• Intranet (full screen, high quality)
• Extranet (variable bandwidth)
• Multicast delivery on-campus
