300 Configuring Hyper-V over Highly Available SMB Storage

300 Hyper-V over SMB What is it? Store Hyper-V files in shares over the SMB 3.0 protocol (including VM configuration, VHD files, snapshots) Works with both standalone and clustered servers (file storage used as cluster shared storage) Highlights Increases flexibility Eases provisioning, management and migration Leverages converged network Reduces CapEx and OpEx Supporting Features SMB Transparent Failover - Continuous availability SMB Scale-Out – Active/Active file server clusters SMB Direct (SMB over RDMA) - Low latency, low CPU use SMB Multichannel – Network throughput and failover SMB Encryption - Security VSS for SMB File Shares - Backup and restore SMB PowerShell - Manageability Hyper-V Cluster File Server Cluster

300 SMB Transparent Failover Failover transparent to server application Zero downtime – small IO delay during failover Supports planned and unplanned failovers Hardware/Software Maintenance Hardware/Software Failures Load Rebalancing Resilient for both file and directory operations Requires: File Servers configured as Windows Failover Cluster Windows Server 2012 on both the servers running the application and file server cluster nodes Shares enabled for “continuous availability” (default configuration for clustered file shares) Works for both classic file server clusters (cluster disks) or scale-out file server clusters (CSV) Hyper-V Failover share - connections and handles lost, temporary stall of IO Normal operation 1 1 Connections and handles auto-recovered Application IO continues with no errors \\fs\share

300 SMB Scale-Out Targeted for server app storage Example: Hyper-V and SQL Server Increase available bandwidth by adding nodes Leverages Cluster Shared Volumes (CSV) 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

300 User Kernel SMB Direct (SMB over RDMA) 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 RDMA-capable network interface (R-NIC) Three types: iWARP, RoCE and Infiniband RDMA NICs should not be teamed (use SMB Multichannel)

300 SMB Multichannel Full Throughput Bandwidth aggregation with multiple NICs Multiple CPUs cores engaged when NIC offers Receive Side Scaling (RSS) Automatic Failover 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 Sample Configurations

300 SMB Encryption End-to-end encryption of SMB data in flight Protects data from eavesdropping or snooping attacks on untrusted networks Zero new deployment costs No need for IPSec, specialized hardware, or WAN accelerators 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 ServerClient SMB Encryption

Getting Started with Hyper-V Replication

300 Hyper-V Replica  Hypervisor level replication  Point-in-time replication of a VM to a remote server  RPO of 5 minutes VHDX

300 Choosing a Disaster Recovery Solution Hyper-V Replica RPO = 5 minutes RTO = Manual (longer) Cost = In-box in Windows Server Complexity = Low Multi-Site Clustering RPO = 0 minutes* RTO = Automatic (fast) Cost = High Complexity = High *depending on 3rd party replication solution

Fault Tolerant Solutions  Fault tolerant solutions can deliver zero downtime for any unplanned hardware failure  Requires special hardware  Gives higher levels of availability for a broader set of unplanned downtime scenarios  Partnership with Stratus  Mission-Critical Hyper-V Systems in lock step

300 Summary  Windows Server delivers a breath of features which can increase the resiliency of your Private Cloud  Windows Server 2012 delivers many new availability features  Delivering a resilient cloud includes planning for: Planned Downtime Unplanned Downtime Disaster Recovery
