Agenda Goals Windows Storage Management today Where we want to be tomorrow Roadmap with interim steps Call to action

Goals For This Session The audience should walk away with An understanding of enterprise storage management capabilities in Windows today An overview of the storage management tools in Windows Server codenamed “Longhorn”. How Windows Storage Management will evolve to Better align Storage and Systems Management Align with the Storage Industry

Storage Management Hierarchy Interfaces Low level functionality such as APIs, drivers, filesystems, etc. Features These are exposed to the user, e.g., Storage Manager for SANs, Storage Explorer, Previous Versions Products Something one would buy, e.g., Windows Storage Server Solutions May consist of multiple parts working together to solve a customer problem, e.g., Information Lifecycle Management Many partner offerings Data Protection Manager

Current Storage Management Interfaces (examples) Hardware support FC and SAS through SM-HBA (WMI, Win32) LUN management through VDS (COM) Snapshotting through VSS (COM) iSCSI Initiator (WMI, Win32) iSCSI Target for Storage Server (WMI) iSNS (WMI) MPIO (WMI) General Storage (WMI – CIMv2)

Current Storage Management Features Storage Manager for SANs (new in Windows Server 2003 R2) File Server Resource Manager (new in R2) Storage Explorer (new in Windows Server Longhorn) Snapshot solutions enabled by the Volume Shadowcopy Service

Current Storage Management Storage Manager for SANs (SMfS)

Current Storage Management Quota Management (FSRM)

Current Storage Management Storage explorer (Windows Server Longhorn)

Volume Shadow Copy Service Features First introduced in Windows XP Hardware based snapshots in Windows Server 2003 Shadow Copies for Shared Folders Ubiquitous in Windows Vista and Windows Server Longhorn Previous versions System restore Safe Docs Windows Server Longhorn Backup

Storage Products Windows Storage Server 2003 R2 iSCSI Feature Pack New higher-end Network Attached Storage offerings coming soon Data Protection Manager Backup of multiple fileservers Builds on VSS snapshots

Current Storage Management Summary High-end Storage Management capabilities being delivered in Windows Server Great progress since Windows 2000 Storage Area Networks can now be deployed by small and medium businesses Fibre Channel and iSCSI Including advanced features like snapshots

Storage Management Futures The following material will present a vision for driving consistency among management paradigms in the Windows platform This is forward thinking and does not represent a commitment to deliver a particular product or feature

Problem Statement Storage management interfaces have evolved using many different models and protocols, often to solve point solutions Each of these has a unique provider model Focused on small parts of the overall storage management puzzle Difficult to update to include new capabilities Not aligned with the storage industry Difficult for customers to locate all the pieces Many interfaces are not remotable, scriptable or can’t traverse firewalls CIM schema implementations are out-of-date and insufficient Too many different tools

Long-Term Objective Align server and storage management Microsoft has adopted WS-Management as the paradigm for managing systems Align server and storage management while preserving the investments partners have made Native Windows hardware providers will still work Shims will be developed to support SMI-S providers Promotion of WS-Management as the protocol of choice for all things management (not just for Windows!) Migration of Windows storage management applications to WS-Management over time Provide a great management (and development) platform Exploit the capabilities of other WS-Management protocols

Storage Management Roadmap Expose and consume storage management information using WS-Management protocols Update schemas to latest DMTF versions for storage functions Migrate older schemas from CIMv2.0 to CIM 2.11 Expose host resources through compliant WMI providers Promote WS-Management protocol adapters Support third party CIMOMs for proxy providers Minimize work for IHVs to support WS-Management Shim VDS to SMI-S (using WS-Management) Most appropriate for larger enterprises Gives vendors an option to support native VDS providers or take advantage of SMI-S investments No plan to deprecate VDS Hardware Provider API Migrate Windows storage apps to WS-Management protocols

Microsoft ISV IHV Shimming VDS To SMI VDS SW Provider API VDS HW Provider API VDS Service VDS Application VDS to SMI-S “Shim” VDS Application (ISV) VDS SW Provider VDS HW Provider SMI-S Server (WS-Man) WS-Management/SLPv2 VDS Client API VDS HW Provider API

WS-Management Enabling third-party CIMOMs SMI Hardware Provider Protocol Adapter cimXML Protocol Adapter WS-Management 3rd Party CIMOM (e.g, Pegasus, OpenWBEM) New Microsoft ISV IHV

CIM Schema Updates Host resources These are resources that are directly attached to a Windows System Devices – disk, tape, changer Interfaces – Fibre Channel, iSCSI, SAS Windows iSCSI target Much of the necessary data is already available, but in different schemas or not in WMI It’s simpler to implement WMI providers for these than to install an entire stack (with a different CIMOM) Benefit from a standardized schema Third parties can extend

WS-Management For Storage WS Protocol Storage InterfaceMechanisms Security WS-Security WS-Trust IPsec IKERADIUS iSCSI Fibre Channel FC-SPDH-CHAP CHAP Common Discovery WS-Discovery iSNS other SNS SSDP Other IP attached iSCSI Fibre Channel Other Host Resources FC-GS-x SLPv2 Management WS-Management VDS VSSSM-HBA SMI FC-GS-xWMI

Storage Management Status WS-Management shipped in Windows Server R2 releases DMTF approved as a preliminary standard More spec work required to support discovery and security Work described in this presentation will begin post-Windows Vista Schema updates being planned VDS Shim work scoped Impact on SMI-S No changes to schemas, profiles, recipes Updates likely for security SOAP interfaces introduced as alternative protocols

Simplify The right tools for each customer Reduce the number of different storage management tools Merge into fewer consoles Support configurations of any size Use remoting for centralized management Current tools require too much work for the simplest configurations Home or Small Office Plug and Play iSCSI SAN should require just a few clicks (and a password!)

Call To Action Stay informed about Microsoft Storage directions Learn about the value of WS-Management Start using this – WMI classes are exposed now and more are coming If you have a VDS provider, customers can still use it VDS APIs and provider models continue to be supported This is important for environments that do not have SMI-S support If you have an SMI-S provider Get it CTP certified by SNIA Test your provider with the VDS HCT and VDS applications when the shim is available If you are using a 3rd party CIMOM, work with your supplier to implement a WS-Management protocol connector
