Target Application Model (2)

• What existing application architectures come close to fitting this model?

  • parallel shared-nothing DBMSs
    • IBM DB2, Teradata, Tandem SQL/MX
  • distributed server applications
    • Lotus Notes/Domino
    • traditional distributed filesystems/fileservers
  • cluster-aware applications (with small mods?)
    • LARD cluster web server (Rice)
    • Microsoft Cluster Server Phase 2 (?)

• What doesn’t fit?

  • simple 2-node “hot standby” failover clusters
    • Microsoft Cluster Server Phase 1
