Scenarios for File and iSCSI Storage
Cloud Windows Client SMB for Information Workers Main features: Continuous Availability, Directory Leasing, Encryption Non-Windows Client NFS for Information Workers Main features: Continuous Availability, Support for both NFS v3 and v4.1 Windows Server Hyper-V over SMB, SQL Server over SMB Host boot from iSCSI Target Main features: Continuous Availability, Scale-Out, SMB Multichannel, SMB Direct, SMB Encryption Non-Windows Server VMware over NFS, VMware over iSCSI Main features: Continuous Availability 15

Windows Server 2012 R2 is cloud optimized
Private Clouds Hosted Clouds Cloud Service Providers Reducing capital and operational storage and availability costs 16

Cloud Deployment Storage Vision
Hyper-V SMB Scale-out File Server Storage Spaces Block Storage 17

Focus Enabling Hosters and the Private Cloud Reducing Costs
Performance Scalability Reliability Manageability 18

Main New Features Performance Diagnosability Optimized Manageability
SMB Direct v2 increases IOPS DFS Replication improvements Diagnosability Improved SMB eventing New SMB event channels, on by default Optimized Automatic SMB Scale-Out client rebalancing iSCSI Target uses VHDX format Manageability New/improved PowerShell for DFS-R and SMB Built-in SMI-S for iSCSI Target 19

SMB Direct Performance Enhancements
Focused on efficiency for small IO workloads Increased current 8KB IOPs from ~300K IOPS per interface in Windows Server 2012 to ~450K IOPS per interface (or higher) in the new release Key to supporting small IO with high speed NICs including 40Gbps Ethernet and 56Gbps InfiniBand Implemented through several techniques including: Batching of operations between SMB and the NIC Use of RDMA remote invalidation Further NUMA optimizations across the stack SMB Direct v2 leverages the new NDKPI v1.2 (RDMA) Backward compatible with the original NDKPI v1.1 20

Multiple SMB Instances
Hyper-V Host 1 Hyper-V Host 2 SMB Client SMB Client Each node in a Scale-Out File Server has two instances of the SMB Server One instance handles incoming traffic from SMB clients accessing regular file shares One instance handles only inter-node CSV traffic (metadata access or redirected traffic) Separate data structures (locks/queues) for regular client traffic and inter-node traffic Improves scalability and reliability of inter-node traffic between CSV nodes Scale-Out File Server File Server 1 File Server 2 Default Instance SMB Server SMB Server CSV Instance SMB Client SMB Client SMB Server CSV Instance Default Instance SMB Server CSV1 (Metadata Owner) CSV2 (Not Metadata Owner) CSV1 (Not Metadata Owner) CSV2 (Metadata Owner) Shared SAS Storage 21

SMB Scale-out Automatic Rebalancing
Scale-Out File Server clients are now redirected to the “best” node for access Avoids unnecessary redirection traffic Driven by ownership of Cluster Shared Volumes (coordination node) SMB connections managed per share (not per file server) when Direct I/O not available on the volume Dynamically moves as CSV volume ownership changes. Clustering is now also balancing CSV volumes automatically. Automatic behavior. No Administrator action.

File Server Cluster for live VHD storage
SMB Bandwidth Limits File Server for library Storage File Server Cluster for live VHD storage SMB Traffic divided into three pre-defined categories: Default, VirtualMachine and LiveMigration. Set a Bandwidth Limit for a category, using PowerShell cmdlets or WMI Get-SmbBandwidthLimit [–Category X] Set-SmbBandwidthLimit –Category X –BytesPerSecond Y Remove-SmbBandwidthLimit –Category X Addresses the new scenario where you can use Live Migration over SMB and RDMA. Matching performance counters so you can observe traffic per category. Default Limit=100MB Virtual Machine No Limit Live Migration Limit=500MB Hyper-V host 1 Hyper-V host 2 VM1 VM2 VM2’ VM3 Set-SmbBandwidthLimit –Category Default –BytesPerSecond 100MB Set-SmbBandwidthLimit –Category LiveMigration –BytesPerSecond 500MB 23

SMB Delegation Domain Controller DC1 File Server FS1 Simplified cmdlets for enabling delegated administration of file servers Useful in certain Hyper-V over SMB scenarios Configured per SMB client/server pair Get-SmbDelegation –SmbServer X Enable-SmbDelegation –SmbServer X –SmbClient Y Disable-SmbDelegation –SmbServer X [–SmbClient Y] Does not require Domain administrator rights Requires 2012 Forest Functional Level, since it leverages the resource-based Kerberos constrained delegation.

NFS Server File sharing for non-Windows Platforms
Windows File Server Cluster UNIX-Linux NFS clients Linux Solaris Mac OS NFS v2/v3/v4.1 File sharing for non-Windows Platforms Interop with major UNIX/Linux clients and VMware Shared access in a heterogeneous environments Same share can be accessed via both SMB and NFS Improved ID mapping Different methods, including Kerberos support Better security and ease of management Supports multiple versions: NFSv2, NFSv3, NFSv4.1 NFS v3 – Continuous Availability for VMware NFS v4.1 – High Availability for client workloads 25

iSCSI Target: Enhancements through GUI
New in Windows Server 2012 R2! Provision virtual disks with sizes up to 64TB Secure zeroing-out on allocation of fixed virtual disks Dynamically expanding virtual disks New virtual disks are VHDX-formatted 26

iSCSI SMI-S Provider for SCVMM
