Agenda

• Situational Summary

• Storage Vision for Branch and Hubs

• Interfaces for Innovation

• Microsoft Storage Roadmap

Customer Situation

Storage Management Is Too Expensive At All Layers

• Block level

• Daily Issues
• Pro-active versus re-active fault management
• Adding/removing disks
• Managing the boot volume
• Capacity planning
• Tension between DAS initial cost of ownership and SAN total cost of ownership

• File Level

• Backup and recovery
• Quotas
• Security management

• System Level

• Managing a distributed environment
• Managing storage consolidation
• System errors which map to storage errors (chkdsk,etc.)

Enterprise Deployment Models

• Server in the Hub

• Headquarters or other central location
• Highly skilled/specialized IT staff
• Provides shared, cross-org infrastructure
• Network is lower latency, higher throughput

• Server in the Branch

• Geographically distinct from hub location, relatively small
• Minimal IT staff
• Infrastructure dedicated to single location
• Network is much higher latency, lower throughput

• Enterprise Desktop

• (out-of-scope for this track)

Consolidation – Branch To Hub

• Server consolidation focus is shifting to branch server consolidation

• Choices are less obvious – TCO gains come with trade-offs

Branch Business Impact

• Branch impact on servers and storage

• 25% of all servers are in branches (nearly 50% in organizations with multiple locations!)
• 30% of businesses have branches
• 33% of IT budgets are consumed by Branches
• 55% of larger organizations’ (1000+ employees) headcount located in branch sites
• Larger organizations (1000+ employees) spent U.S. $25B on WANs in 2003

• However

• Traditional market trackers don’t track branch contributions to storage

Storage Vision

Universal Distributed Storage

Universal Distributed Storage

Universal Distributed Storage A standards based platform with strong partnerships

• Industry-standard hardware and interfaces

• Strong support for evolving hardware standards
• INCITS T10 – SAS
• INCITS T11 – Fibre Channel, SM-HBA, FC-HBA
• INCITS T13 – SATA
• New interfaces
• IETF – iSCSI, iSNS
• SNIA – Fixed Content Addressable Storage (FCAS), SMI-S
• DMTF – WS-Management
• NFS as a first tier file system

• Mainstreaming high-end technology

• Today: MPIO, Snapshots, iSCSI target, Storage Explorer, SIS
• Tomorrow: Transactions, Fixed Content Storage

• Rich partner ecosystem

Rich Partner Eco-System Some of our valued partners in storage

Universal Distributed Storage Beyond file data – DAS, NAS, SAN, CAS

• Storage Fabric as easy to deploy as file shares

• Preferred Storage Platform
• Early fault detection
• Simple SAN
• Simple Management for SANS (SMfS)
• Web Services Management (WS-Management)
• Diskless Boot

• Enhanced application robustness and capabilities through new storage semantics

• Transactional File System
• Common Log File System
• Fixed Content Storage (Content Addressable Storage)

Universal Distributed Storage Beyond file data – Transactions

• Transacted File System – Enables more robust application behavior for complex operations – examples

• Registry updates
• Updates to multiple files on the same volume
• Updates to multiple files across multiple volumes
• Updates to multiple local and remote files

• Transacted Platform

• Common Log File System
• Filter Manager
• Kernel Transaction Manager

Universal Distributed Storage Ubiquitous and always accessible

• Reliable and Scalable

• Multi-pathing fail-over and load balancing
• Single Instance Store (SIS)
• Self healing NTFS
• Symbolic Links
• Volume Manager
• Large sector drives
• LUN/Volume Shrink

• Easy integration into Unix environments

• Services For Unix (SFU) is now part of the OS

• Easy backup and recovery

• Snapshots
• Data Protection Manager

Universal Distributed Storage Innovation for the branch office

• Better replication – reduction of WAN bandwidth

• DFS-Replication – differential compression
• New improvements in SYSVOL and on-demand replication

• Improved performance

• SMB 2.0
• Client Side Cache (CSC) improvements
• Filecopy performance

• Improved security within the branch

• Secure Startup
• Read-Only DC

• Easier to deploy

• Appliance: Full-featured branch office SKU

Branch Office Vision

• Clients failover to a central server

• Service cache

• Easy to re-provision replacements

Windows Server 2003 R2 Performance improvements

• NFS version 3 Spec SFS97*

• UDP 23064 (prior Windows Server 2003 best was 13319)
• TCP 22416 (prior Windows Server 2003 best was 9209)

Remote Differential Compression (RDC)

• New protocol that identifies sub-file changes

• Updates to objects: Efficiently detects insertions, removals, re-arrangements of data in files
• New objects: Efficiently discovers and re-uses relevant pieces of object on receiving machine
• Dramatic reduction in bandwidth consumption

• Generalized technique – completely file type agnostic

Longhorn and Vista Beta 2 Status: Remote Filesystem Perf

• Current Vista & Longhorn improvements:

• SMB 2.0 protocol has pipelined transfers
• CopyfileEx pipelining
• Cache manager and memory manager deferred writes
• TCP receive window auto-tuning

• Future improvements: small file workloads

• Benchmark details

• Data presented today is just a status report
• Xcopy used to move the data
• Hi-Perf client and server disks (10K RPM, RAID)
• Vista build 5306 and 5294
• WAN latency is emulated on a 1 gigabit Ethernet

Filecopy and SMB 2.0 Performance
