Overview Traditional Storage Offering Current Storage Offering Emerging Technologies / Future Offerings

Overview: Environments Enterprise Systems – Mission Critical Storage Solutions provided as agency-wide service offering. Platforms include: Solaris, Linux, Windows, AIX, VMware, Mainframe Environments Included are: 311 – City Services Call Center NYC.gov – Public Web Portal NYCSERV – Department of Finance Revenue Application Exchange – Citywide Solution Cityshare –Employee Internal Web Portal GIS – City Geographical Information Services Interwoven – Content Deployment System Analytics – Enterprise Reporting System

Overview: Data Storage Highlights Disaster Recovery Solutions – Multi-site redundancy Data Replication – Block and File level for high availability DWDM Fiber Channel connection between three sites 311 Call Center Data Data Types: Flat Files, Block Devices, Exchange, Oracle, SQL GIS Citywide Geographical Imaging

Silo approach Most systems – static-size internal disk Dedicated direct attached array for additional needs Limited “shared array” solutions Standalone arrays Enterprise Storage: Traditional Offering (prior to 2004)

Traditional Storage Offering: Issues Rapidly growing data sets Risk of data loss Multiple array failures – risk of data loss Extensive downtime due to disk failure Extensive maintenance windows “Ad-Hoc” replication, file copy strategies for DR Inability to forecast and meet storage demand High cost due to dedicated storage procurements

Solution: Enterprise Storage Area Network (2004 – 2006) Ability to quickly grow data sets Implement Shared Fabric Centralize critical storage Enhanced capacity planning and provisioning Lower overall costs Increased security, manageability

Storage: Hitachi Storage Array NetApp Filers Shark Storage Array SATA Storage Array Data Protection: Veritas Netbackup Traditional Tape Backup and Archiving Offsite Vaulting StorageTek Tape Silos Overview: Technology Solutions

Fabric Architecture – Brocade 12k, 48k, 4900 “Core-Edge” Topology. Bandwidth 1 to 4 Gbps High performance, redundant Robust, highly reliable / scalable Established Fibre Channel Infrastructure Based on best practices and industry experience Increasing demand for more bandwidth Expanding requirements for greater port density Greater need for Fabric / Storage segregation Current Offerings: SAN / Fabric

Enterprise Storage: Hitachi 9990 / 9980 Series Consolidated Approach for Data Center Storage Highly Integrated Service Offering Reduced Cost per unit of Storage Enhanced and streamlined supportability Efficient Utilization of Costly Disk Resources Simplified Provisioning, Virtualization, and Data Migration Enhanced Accessibility to Data Sets for SOA initiatives

Transition to Tiered Storage Model Continue “Core” Enterprise-class Storage - Mission-critical data Implement SATA technologies for 2 nd Tier Data SAN Segregation allows N-level Storage Tiers Facilitates data migration, Lifecycle Management Enterprise Storage: Tiered Storage

Enterprise Systems: NetApp Filers Windows Systems – Due to unique replication and storage needs particular to the Exchange environment, NetApp Filer Technology will be used to house the Windows environments. This approach allows Exchange to run in a storage environment that has been optimized and supported by Microsoft. Environments Included are: Exchange – Citywide SQL Server – Microsoft Database Solutions Windows Hosting – Other Application Systems hosted on Windows

Security Fabric Security – Brocade Secure OS under implementation Access Control Lists Restricted Access Centralized and Consolidated Storage Administration

Traditional tape backup & recovery Highly robust, reliable Mature technology Based on best practices and industry experience Increasing need for faster backup, recovery times Need to minimize backup windows, increase data availability Current Offerings: Backup & Recovery

Virtual Tape Library (VTL) Faster Backup and Restore Times Reduced Application Impact Smaller Backup Windows Potential for Continuous Backup and Recovery Windows Allows for Disk-level Replication (DR strategy) Planned Expansion: Backup & Recovery

Enhanced Offsite / DR Capability Cluster-enabled Backups “Offsite capabilities to FISA” Immediate availability of DR Backup Environment Immediate availability of Offsite Tape / Disk Integrate with VTL to enhance Recovery Time Planned Expansion: Backup & Recovery

Need for Enterprise-scale Solution Must be heterogenous, vendor neutral Allow end-to-end management Allow end-to-end problem isolation AppIQ, EMC offer promising solutions (among others) Reduces “Shelf-ware” effect of disparate tools Information Lifecycle Management Emerging Technologies: Storage Resource Management

Optimized Provisioning Facilitates tiered storage model Multi-protocol access points: NAS, FC, iSCSI Multiple vendor offerings in this space Technology in infancy stage Multiple approaches: Appliance approach “Core” approach Emerging Technologies: Virtualization
