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.)
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)
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
- 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
- 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 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
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
