  1. State Street Storage Replicator (SRVM) Deployment For Open Systems

  2. GLOBAL DATA CENTERS • DATA CENTERS • Quincy, MA • Westboro, MA • London • Sydney, Australia • Kansas City, Missouri (future) • Distance • Quincy, MA to Westboro, MA 45 Miles • Boston, MA to Kansas City, MI 1,500 Miles • Client Server • Quincy & Westboro have 574 + production servers • London and Sydney have 45 + production servers • 14 terabytes of disk storage

  3. PLATFORM SUN HP IBM NT STORAGE EMC NATIVE DISKS OPEN SYSTEMS ENVIRONMENT • VERITAS • VOLUME MANAGER • FILE SYSTEM • STORAGE REPLICATOR • FIRST WATCH CLUSTER (HA) • REPLICATOR EXEC

  4. AVAILABILITY • FirstWatch, Service Guard and HACMP • Systems have to be in the same physical location • ADSM • Systems restore time • Backup data off-site • Database Replication • Sybase • Oracle • Informix • Microsoft SQL Server • Systems have to be in the same physical location

  5. GEOGRAPHIC MIRRORING • Veritas SRVM • Enhances Veritas volume manager to provide remote mirroring • Uses standard TCP/IP transport • Transparent to application • Cost-effective • Two modes of operation: • SYNCHRONOUS - PRODUCTION MODE • ASYNCHRONOUS - TBD

  12. APPLICATIONS PENDING ForSRVM DEPLOYMENT • Insight • Corporate Actions • Security servers • Intrader

  13. SRVM Performance • Tested at State Street starting Fall 1998 • No measurable performance effect at low write intensity (Nav Alert) • Performance degradation 10% at high write intensity (50 writes/second - CSW)

  14. Replication Performance • Writes per second are limiting factor • Limitation on replication is usually link latency, not bandwidth • Latency increases with distance - a severe problem at long distance, even with ‘high speed’ links

  15. SRVM REQUIREMENTS/ISSUES • GUI Interface • Higher level configuration/management commands • Automatic synch checks and re-synch • Functional with symmetric First Watch or Cluster server • Up-to-date documentation • Cookbook
