  • Overview
    • Storage Virtualization
      • Heterogeneous virtualization (in-band)
      • Array based virtualization (code on controller)
    • Server Virtualization
      • VMWare ESX/Infrastructure
  • History 2004/2005 - (1)
    • In 2004 SHU had stand alone servers and various disk islands
    • Most storage was direct attached
    • Standard “1U” rack servers, one per application
  • History 2004/2005 - (2)
    • IBM 2105 - ESS “Shark”
      • Direct attached via SCSI
    • Several stand alone IBM disk units
      • Direct attached via SCSI
    • Each server had local disk
      • Different controllers, RAID replacement procedures
  • Architecture Changes (1)
    • Implement SAN
      • Reduce dependency on direct attached disk
      • Provide more centralized management of disk
    • Reduce server sprawl
      • Research Virtual Machine technology
    • Focus on Blade technology
      • Smaller size, power, and cabling requirements
  • Systems (Blades)
    • IBM Blade Center Technology
      • Modular design
      • Includes Network, Storage Switch, and Management in single chassis
      • Lower power requirements for servers
      • 70 Servers per rack
      • Boot from SAN for no moving parts on blades
  • Architecture Changes (2)
    • Implement SAN
    • Reduce server sprawl
    • Focus on Blade technology
    • - Storage Virtualization -
  • Storage (SAN)
    • SAN Storage

      • StorageTek Flex380
      • Infortrend
    • SAN Switch/Infra
      • qLogic SANBox 9000 (Blades)
        • Up to 256 Ports
        • Ability to expand SAN to other buildings/long distance (DR, etc)
  • Storage Virtualization (1) Blade 1 Blade 4 Blade 2 Blade 3 SAN Switch 1 SAN Switch 2 IPStor 1 IPStor 2 DS8000 Flex380 Server San Switch Virtualization Storage
  • Storage Virtualization – (2)
    • FalconStor IPStor software
      • “ Virtualizes” all storage, allows resize, assign/remove on the fly
      • Allows mirroring/physical disk moves with no downtime (between multiple physical storage units)
      • Single “pane of glass” management for all storage
      • Freedom from vendor limitations (LUNs, sizes, etc)
      • Snapshots of live data possible
  • Storage Virtualization – (3)
    • FalconStor IPStor software (v5.1)
      • In-band solution
      • Active/Active cluster
      • Single software interface for all management (Linux/Windows)
      • Clients available for snapshots for Oracle, Notes/Exchange, SQL Server, etc
  • Storage Virtualization – (4)
    • Tasks for administrators:
      • Mirror data (Upgrades, backups)
      • Move data
      • Add additional storage from selected tier
      • Add new servers to storage pool
  • Storage Virtualization – (5)
    • Mirror Command
      • Move data
      • “ Swap” mirrors
      • “ Promote” mirror to primary storage
    • Moving storage from one array to another
  • System Performance
    • Applications currently utilizing storage virtualization – 70+ server clients
      • Lotus Domino (campus wide)
      • Sungard Banner (Approx 12 instances with multiple add-ons)
      • File/Print services (campus wide)
      • Content management system
      • Luminis Portal
      • VMWare ESX Server
  • Additional Features
    • Replication
    • “ Hot Zone”
    • Snapshots
    • Reports
  • Storage Virtualization - Future
    • Fully integrate Dynapath/Multipath
    • Full 4Gbps SAN connections
      • Overcomes 2Gbps queue depth issues
    • Increase number of targets to hosts
  • Storage Virtualization - Review
    • Single pane of glass for administration
    • Migration between physical disk arrays is a non-issue
    • Simplification means no full time storage administrator necessary
    • Avoid Single Point of Failure
