Platform Storage – Disk I/O

ODX Benefits• Rapid virtual provisioning and

migration• Faster transfers for large files• Array throughput maximization• Less CPU and network usage• Performance not limited by network

throughput or server usage• Improved data center capacity and

scale

Offloaded Data Transfers (ODX)

Token-based copy operation


Platform Storage – Local File System

• ReFS File System• Greater compatibility

with SATA standards• Resilience against

power outage corruption

• Online corruption recovery

• Scale to petabyte+ data sets

• Implements on-disk structures, such as the Master File Table, to represent files and directories.

13

New Storage Capabilities with Resilient File System (ReFS)


Platform Storage – Local File SystemNTFS Availability, Reliable Crash Recovery, and Improved SATA Reliability

• NTFS/ReFS self-healing capabilities

• Automated health checking on NTFS

• Chkdsk improvements reduce downtime

• Improved SATA reliability

Time to complete Chkdsk operation on a single instance of corruption in minutes



• Capacity Optimization• 2:1 with File Shares• 20:1 with Virtual

Storage

• Scale and Performance• Low CPU & memory

impact• Configured

scheduling

• Reliability and Integrity• Redundant metadata• Checksums and

integrity checks

• Even greater efficiency with BranchCache
