7. Storage: Demand Demand  Reference data growth  IT cost/efficiency  Digital media Optical Drive Adoption In PC’s (source: NPD Techworld) Transition to Reference Information (source: Enterprise Storage Group)

8. Storage Devices: Inflection Points What’s Changing? Previous Generation New Generation Optical storage devices supported per application for specialized media uses  DVD devices break records for speed of technology adoption  Digital media playback and authoring become mainstream applications Optical storage devices are part of the platform, enabling mainstream application innovation Optical Platform Client/Consumer Small storage capacities used to cache data for later offloading to a PC  Multi-gigabyte flash memory with steep cost reductions  High-bandwidth device connectivity  Inexpensive micro- drive technologies Personal storage supports portability at the application and system level Personal Storage Client/Consumer SMORG server storage primarily direct-attached (DAS)  IP-based SANs lower purchase costs  Availability of simple installation and management tools SMORG server storage primarily fabrics of efficiently managed modular storage devices Storage Fabrics Server/Enterprise

Storage Devices: Key Windows Strategies Optical Platform Client/Consumer Storage Fabrics Server/Enterprise Personal Storage Client/Consumer Preferred Storage Platform Partner/Customer Timely, comprehensive, quality platform support for optical devices Optimized platform features enabling new customer scenarios in Personal Storage Leading platform supporting storage fabrics Preferred platform for developing, integrating, and deploying storage devices

10. Storage Fabrics Feature Roadmap iSCSI Currently: Out of Band Release (on Web) iSNS 3.0 – December 2004 High availability through MSCS resource DLL iSCSI v2.0 – “Osaka” Integrated MS-MPIO MS iSCSI DSM supports standards-conformant iSCSI targets Updates to support VDS 1.1 Improved UI Error Recovery Levels 1 and 2 Planned for Windows codenamed “Longhorn”: It’s in the box Client (iSCSI) and Server (iSCSI & iSNS server) Internet Authentication Service (IAS) Radius plug-in for iSCSI centralized security management Storage Fabrics Server/Enterprise

11. Storage Fabrics Feature Roadmap MPIO: Microsoft Multipath Solution Currently: Out of Band Release (on Web) Updated DDK (1.13) – March 2005 Including VDS 1.1 updates New sample DSM (iSCSI) Planned for Longhorn Server: It’s in the box Industry standard solution Includes support for Active/Active arrays Supports Asymmetric A/A (SPC-3 compliant) Load balancing with MSCS clusters DDK still available Investigating shipping 3 rd party DSMs Storage Fabrics Server/Enterprise
