Microsoft Core Storage Update March 2006 Suzanne Morgan, Program Manager Core Windows, Storage

iSCSI 2.0 Key Features Integrated Microsoft MPIO multipathing solution supports logo’d block storage devices Includes Microsoft iSCSI DSM designed to work with SPC-3 compliant or active/active targets Multiple connections per session IPv6 support Error Recovery Levels 1 & 2 Persistent Reservations Multiple load balance policies and failover policies

iSNS Server 3.0 Microsoft preferred mechanism for iSCSI target discovery Scalable iSNS support required for all iSCSI targets through designed for Windows Logo Program Centralized management using Discovery Domains DHCP support for auto configuration Dynamically updated Cluster resource DLL enables failover support WMI provider

Microsoft Multipath I/O DDK High Availability Storage Solution Microsoft foundation binaries included HBA and path agnostic Provides up to 32 paths Enables full path control by DSM Failover, Failback and Load Balancing Device Specific Modules Vendor DSM tunes MPIO to storage device Multiple DSM coexistence   WMI interface provides consistent management capability Can send storage unique commands

Microsoft MPIO Roadmap Longhorn Server: Integrated Multipathing Microsoft DSM - Industry standard multipath solution iSCSI, FC, SAS Support for Active/Active arrays Supports Asymmetric A/A (SPC-3 compliant) Load balancing with MSCS clusters Persistent Reservation Requirement for DDK still available! – MS DSM Source Included Proprietary or “classic” Mulitpathing will no longer be logo’d for FC True today for iSCSI and SAS

iSCSI Software Enabled SAN Boot Diskless boot enabled using standard NICs + Microsoft iSCSI Software Initiator Requires firmware based change in System Option ROM or NIC ROM/firmware Key scenarios Diskless blade servers to address power/heat consumption Disaster recovery Manageability Release mechanism Solution Provider/OEM/IHV provided Includes Microsoft QFEs redistributed by OEMs Includes IHV provided firmware implementation Targeting release IH06 – Windows Server 2003 LH Server will support CD install to diskless server

Microsoft iSCSI Software Target Software target, based on acquisition Delivery for WSS R2 via “iSCSI feature pack” Includes support for: MS MPIO VSS VDS 1.1 VHD format 64-bit Windows (amd64) IPsec IPv6 Windows Core Technology - Microsoft Confidential 7 Windows Core Product Team, Storage - Microsoft Confidential 7

Appendix

Planned Features for Windows Vista and Windows Longhorn Server

Microsoft iSCSI Software Target (Futures) ERL 1 & 2 Multiple connections per session (MC/S) Mirroring (2-node replication) “Flash copy” (COW snapshots and clones) Snapshot agents for SQL, Exchange, VSS Replication of snapshots Radius Support Windows Core Technology - Microsoft Confidential 10 Windows Core Product Team, Storage - Microsoft Confidential 10

iSCSI Software Initiator Updates Initiator included inbox both client and server Support for WinSock Kernel (vs. TDI) Support for CD-based Install to diskless servers iSCSI Initiator modified to support WinSock Kernel (vs. TDI) to take advantage of performance enhancements in Longhorn Server

End to End Multipathing: Microsoft MPIO Universal DSM Supports Fibre Channel and SAS as well as iSCSI Provides user community with low-cost, high-quality multipathing solution Meets enterprise requirement for highly available storage Compatible storage arrays must comply with relevant SCSI Standards Additional value add available using vendor provided plug-in (DSM)

Management & Security Storage Explorer iSNS Server included inbox in Longhorn Server Manageable through Storage Explorer IAS radius plug-in for Microsoft IAS Server enabling iSCSI centralized security management with Radius Server

Storage Explorer: A SAN Visualization Application Storage Explorer Design Utilizes industry standard APIs to gather information about storage devices in FC and iSCSI SANs Implemented as an MMC snap-in Access to iSCSI/iSNS Device Configuration Storage Explorer GUI Provides a tree-structured view of all the components within the SAN (Fabrics, Platforms, Storage Devices, LUNs) Storage Explorer Management Provides access to the TCP/IP management interfaces of individual devices from a single GUI Administrator Challenges Administrators want SAN benefits, but They want SAN management functionality to be integrated into the OS

Storage Explorer: User Interface SAN Visualization Provides detailed SAN configuration information

Storage Explorer : User Interface Device Management Provides access to the management interfaces for individual devices
