Agenda Situational Summary Storage Vision for Branch and Hubs
Interfaces for Innovation Microsoft Storage Roadmap
3
Customer Situation Disk Replacing Tape Distributed Environments
Moving Beyond File Data Management costs
4
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.)
5
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)
6
Consolidation – Branch To Hub
Server consolidation focus is shifting to branch server consolidation Choices are less obvious – TCO gains come with trade-offs Servers in central sites? Servers in branch sites? or Lower server management costs WANs decrease branch productivity Many application not tuned for lower bandwidth, higher latency, availability of WAN Higher server management costs Backup, recovery, repair, etc… Increases branch productivity/autonomy
7
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 Sources: Harte-Hanks 2004, AMI Partners 2003

Universal Distributed Storage
Industry-standard hardware Mainstreaming high-end technology Rich partner ecosystem Distributed Ubiquitous and always accessible Datacenter, departments and branch offices DAS, NAS, SAN, CAS
11
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
12
Rich Partner Eco-System Some of our valued partners in storage
Storage Servers Storage Arrays SAN Interconnects
13
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)
14
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
15
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
16
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
17
Optional Disposable Replaceable Continuity of Services
Branch Office Vision A simple, self-healing, self diagnosing, “admin-free” server Optional Disposable Replaceable Clients failover to a central server Service cache Easy to re-provision replacements Service Accelerator State-of-the-art compression Limits bandwidth usage Mitigates WAN latency Continuity of Services Local request handling Store-and-forward to central server

Windows Server 2003 R2 Performance improvements
NFS version 3 Spec SFS97* UDP (prior Windows Server 2003 best was 13319) TCP (prior Windows Server 2003 best was 9209) *Based on HP hardware. See for full information
19
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 409 400 350 300 250 200 150 100 50 292 92 41 30 31 17 15 13 3 450 .VSD 318 K .DOC 489 K 2.6 M .MPP 241K .PPT 594K .XLS 2.4M .ZIP 348K .HTM 425K 3.9M .PST 293M

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
