Cluster-Wide File System (CSVFS)

Metadata or redirected IO
CSVFS CSVFS is a clustered file system Enables all nodes to access common volumes Single consistent namespace Provides a layer of abstraction above on-disk file system Application consistent distributed backup Interoperability with backup, AV, Bitlocker Supports NTFS and ReFS on-disk file systems Support for Storage Spaces Transparent fault tolerance Does not require drive ownership changes on failover No dismounting and remounting of volumes Faster failover times (aka. less downtime) Workloads Hyper-V and SQL Server Scale-Out File Server SMB Server (default) Metadata or redirected IO CSVFS Direct IO SMB Client (CSV) Block redirected IO CSV Volume Storage Node 1 SMB Server (default) SMB Server (CSV) CSV Filter CSVFS NTFS / ReFS Volume CSV Volume Space Storage Node 2

CSVFS components CSV File System (CSVFS) CSV Volume Manager CSV Filter
Proxy file system on top of NTFS or ReFS Mounted on every node Decides direct IO vs. file system redirect IO CSV Volume Manager Responsible for the creation of CSV volumes Direct IO for locally attached spaces and Block-level IO redirect for non-locally attached spaces CSV Filter Attaches to NTFS / ReFS for local clustered spaces Controls access to the on-disk file system Co-ordinates metadata operations SMB Server (default) Metadata or redirected IO CSVFS Direct IO SMB Client (CSV) Block redirected IO CSV Volume Storage Node 1 SMB Server (default) SMB Server (CSV) CSV Filter CSVFS NTFS / ReFS Volume CSV Volume Space Storage Node 2 CSVFS support for NTFS features and operations

CSVFS Zero Downtime CHKDSK
Improved CHKDSK with online scanning separated from offline repair With CSV repair is also online CHKDSK processing with CSV Cluster checks (once a minute) to see if CHKDSK (spotfix) is required Cluster pauses the affected CSV file system and dismounts the underlying NTFS volume CHKDSK (spotfix) is run against only affected files for a maximum of 15 seconds The underlying NTFS volume is mounted and CSV namespace is un-paused If CHKDSK (spotfix) did not process all records Cluster will wait 3 minutes before continuing Enables a large set of affected files to be processed over time If corruption is too large CHKDSK (spotfix) is not run and marked to run at next Physical Disk online

Cluster-Wide File System
Scalability Single namespace Aggregate all file systems No more drive letters Leverages mount points Availability Fault tolerance Fast failover on failures Zero downtime CHKDSK Operability Shared access All nodes can access volumes Simple management Manage from any node Performance CSV Block Cache 7x faster VDI VM boot time (avg.) Block level I/O redirection

Scale-Out File Server

SMB Transparent Failover
Planned and unplanned failovers with zero downtime SMB Client Server node failover is transparent to client side applications Small IO delay during failover SMB Server Handles are always opened Write-Through Stores handle state in Resume Key Filter (RKF) DB Resume Key Persists protocol server state to file Reconciles handle reconnects/replays with local file system state Protects file state during reconnect window Witness Service Clients proactively notified of server node failures Clients can be instructed to switch server nodes Hyper-V Host VM VM VMBUS VHD Parser B/W Limiter DPM SMB Client SMBD WSK VSS NDK TCP Witness Client RVSS Provider LBFO To Witness Service On SOFS node 2+ NIC Pair 1 NIC Pair N SMB Server Witness Service RVSS Service CSVFS Server Service DNN Resource Cluster Resume Key SOFS Resource Shared VHD VSS DB NTFS/ReFS CSV Provider LUN / Space SOFS Node 1

SMB Scale-Out Scaling out for throughput and management Scale Out

FAQ Support for IW workloads? CSV caching size?
Not recommended CSV caching size? SOFS is not CPU or memory bound  go big on cache (64GB) Using SOFS for file share witness? Yes you can, see How many nodes? Commonly 2-4 nodes. Usually gated by SAS storage connectivity. How to evaluate performance? DO NOT USE FILE COPY!! Do performance measurements in virtual machine. After all this is the workload  Should I disable NetBIOS? Yes!

Scale-Out File Server is for Hyper-V and SQL Server

This means that Offline Files will stay online even if the user no longer has access to the share, for 3-6 minutes.
