AGENDA Introduction NAS versus SAN SAN Issues Sample Implementations Summary
SYSOP and ICL ICL customer (Trimetra DY) ICL is a SYSOP partner Business dependency on VME VME Longevity –Cost of Ownership –Ease of integration
SYSOP Strategy Build on SYSOP Core Competences –Storage Management –Data Centre disciplines –Service Management skills –Training Increase Capabilities via Partnerships
SYSOP Accreditations
Drivers for Networked Storage Data Warehouses Intranets, Extranets, e-commerce Scalability Demand for resources Heterogeneous Systems Mission critical Laptop data
Network Attached Storage Clients Little or no data held locally Servers Little data held locally Local Area Network Disc Storage Tape drive or Robot File IO
Storage Area Network Clients Little or no data held locally Servers Little data held locally Local Area Network Tape drive or Robot Disc Storage Storage Area Network FABRIC
Comparing SAN and NAS
Advantages of Storage Area Networks Overcomes SCSI limitations Eliminates distance limits LAN-Free Backup Server-less Backup Remote Vaulting Shared storage resource Centralised management High Availability “Mainframe” attributes
Storage Area Network Clients Little or no data held locally Servers Little data held locally Local Area Network Tape drive or Robot Disc Storage Storage Area Network FABRIC
SAN / NAS issues Cost of SAN Infrastructure SAN Standards Bandwidths Where does VME fit ? Management and Consolidation
Evolutions in Data Centres Distributed departmental systems “Harvesting” of servers Policies for legacy applications Strategies for UNIX, Windows NT Centralised backup Consolidation of servers Consolidation of storage Network Attached Storage Storage Area Networks
PADUA Library Control S/W on NT Server Industry Standard Wide portfolio of Libraries for VME VME/Windows NT/UNIX Sharing Full Library Functionality: –All Quantum | ATL Libraries –All M4 Data Libraries –Validated StorageTek Libraries
Library Configuration OSLAN PADUA SCSI control path CONTROL PATH DATA PATH VME LIBRARIAN SCSI TAPE LIBRARY
PADUA Control Paths PADUA control path Tape Library VME RCS task or LIBRARIAN Legato (Networker) Backup Server Veritas ( NetBackup or Backup Exec ) Backup Server Data paths not shown
Customer 1 Requirements –Upgrade Backup Manager to Networker –Centralise Backup Issues –Retain 9710 –Low budget
Implementation 1 Windows NT / Unix / Novell Servers Network PADUA Data path to library drives not shown 9710 VME Networker Backup Server LIBRARIAN
Customer 2 Requirements –Strategic Implementation –Investment protected –Test and Evaluate –Phased Implementation Issues –VME –Budget held outside IT
Implementation 2 Windows NT / UnixWare Servers 9710 PADUA VME NetBackup Backup Server LIBRARIAN FABRIC Disc Storage t.b.a. for consolidation & serverless backup
Customer 3 Requirements –Centralised backup –Stable VME, growing NT –Data Interchange
Implementation 3 Windows NT Servers PADUA VME BackupExec Backup Server LIBRARIAN Ethernet Tape Library Ethernet 36-track Tape Library
SAN Strategy Phased implementation Build on what you have SAN bridges for compatibility Add SAN fibre, Hubs, Switches SAN ready storage
Summary SAN promises huge benefits SAN or NAS is a Strategic issue No need for “big bang” Prioritise - Backup, Consolidation, VME SYSOP is established in the NT market SYSOP can offer unique ways forward
