title Hyper-V over SMB - Overview

Beyond Virtualization The Power of Many Servers, the Simplicity of One Every App, Any Cloud Modern Workstyle, Enabled Windows Server 2012 offers a dynamic, multi-tenant infrastructure that goes beyond virtualization to provide maximum flexibility for delivering and connecting to cloud services. Windows Server 2012 offers excellent economics by integrating a highly available and easy to manage multi-server platform with breakthrough efficiency and ubiquitous automation. Windows Server 212 is a broad, scalable and elastic server platform that gives you the flexibility to build and deploy applications and websites onpremises, in the cloud and in a hybrid environment, using a consistent set of tools and frameworks. Windows Server 2012 empowers IT to provide users with flexible access to data and applications from virtually anywhere on any device with a rich user experience, while simplifying management and helping maintain security, control and compliance.

Failover transparent to server application Zero downtime – small IO delay during failover Supports planned and unplanned failovers HW/SW Maintenance HW/SW Failures Load Rebalancing Hyper-V Resilient for both file and directory operations Requires: Windows Failover Clusters Both server running application and file server cluster must be Windows Server “ 8” Shares enabled for ‘continuous availability’ \fs 1share File Server Cluster File Server Node A File Server Node B

Hyper-V Cluster (Up to 64 nodes) Targeted for server app storage Example: Hyper-V and SQL Server Increase available bandwidth by adding cluster nodes Key capabilities: Active/Active file shares Fault tolerance with zero downtime Fast failure recovery CHKDSK with zero downtime Support for app consistent snapshots Support for RDMA enabled networks Optimization for server apps Simple management Data Center Network (Ethernet, Infini. Band or combination) Single Logical File Server (\FSShare) Single File System Namespace Cluster Shared Volumes File Server Cluster (Up to 8 nodes)

Advantages Scalable, fast and efficient storage access High throughput with low latency Minimal CPU utilization for I/O processing Load balancing, automatic failover and bandwidth aggregation via SMB Multichannel Scenarios High performance remote file access for application servers like Hyper-V, SQL Server, IIS and HPC Used by File Server and Clustered Shared Volumes (CSV) for storage communications within a cluster Required hardware SMB Client SMB Server Application User Kernel SMB Client Network w/ RDMA support R-NIC SMB Server Network w/ RDMA support NTFS SCSI R-NIC Disk

Sample Configurations Full Throughput Bandwidth aggregation with multiple NICs Multiple CPUs cores engaged when NIC offers Receive Side Scaling (RSS) Single 10 Gb. E RSS-capable NIC SMB Client SMB Multichannel implements end-to-end failure detection Leverages NIC teaming (LBFO) if present, but does not require it Automatic Configuration SMB detects and uses multiple paths Multiple 1 Gb.

End-to-end encryption of SMB data in flight Protects data from eavesdropping/snooping attacks on untrusted networks Zero new deployment costs No need for IPSec, specialized hardware, or WAN accelerators Client Server Configured per share or for the entire server Can be turned on for a variety of scenarios where data traverses untrusted networks Application workload over unsecured networks Branch Offices over WAN networks SMB Encryption
