  2. Session 2 Overview • Configuring the Storage Layer • Physical Network • Configuring Virtual Networking • Bringing the Hypervisor Under Management

  3. Configuring the Storage Layer

  4. New Technologies in the Storage Layer Windows Server 2012 introduces technologies at the storage layer that can replace traditional SAN Storage Spaces SMB 3.0 Scale-Out File Server When leveraged together, these enable high performance, ease administration and lower cost

  5. Storage Spaces • Storage spaces use a pooling model - affordable commodity hardware is put into a pool and LUNs are created from these pools: • Supports mirroring and parity for resiliency • Works with Windows clustering technologies for high availability • Existing backup and snapshot-based infrastructures can be used. Storage Pool

  6. Storage Spaces • Virtualization of storage with Storage Pools and Storage Spaces • Storage resilience and availability with commodity hardware • Resiliency and data redundancy throughn-way mirroring (clustered or unclustered) or parity mode (unclustered) • Utilization optimized through thin and trim provisioning and enclosure awareness • Integration with other Windows Server 2012 capabilities • Serial Attached SCSI (SAS) and Serial AT Attachment (SATA) interconnects Windows Application Server or File Server Physical or virtualized deployments File Server Administration Console Hyper-V SMB Multichannel Integrated with otherWindows Server 2012 capabilities Failover Clustering SMB Direct NTFS Cluster Shared Volume NFS Windows Storage Mgmt. WindowsVirtualizedStorage Storage Space Storage Space Storage Space Storage Pool Storage Pool PhysicalStorage (Shared) SAS or SATA

  7. Application storage support – SMB 3.0 Hyper-V Cluster • Highly available, shared data store for SQL Server databases and Hyper-V workloads • Increased flexibility, and easier provisioning and management • Ability to take advantage of existing network infrastructure • No application downtime for planned maintenance or unplanned failures with failover clustering • Highly available scale-out file server • Built-in encryption support Microsoft SQL Server SMB Single Logical Server \\Foo\Share File Server Cluster Cluster Shared Volumes Single File System Namespace WindowsVirtualizedStorage Storage Space Storage Space Storage Space SAN RAID Array RAID Array RAID Array Storage Pool Storage Pool PhysicalStorage

  8. Efficient storage through Data Deduplication • Maximize capacity by removing duplicate data • 2:1 with file shares, 20:1 with virtual storage • Less data to back up, archive, and migrate • Increased scale and performance • Low CPU and memory impact • Configurable compression schedule • Transparent to primary server workload • Improved reliability and integrity • Redundant metadata and critical data • Checksums and integrity checks • Increase availability through redundancy • Faster file download times with BranchCache VHD Library Software Deployment Share General File Share 0% 20% 40% 60% 80% 100% User Home Folder (My Docs) Average savings with Data Deduplication by workload type Source: “Microsoft Internal Testing"

  9. Improved network performance through SMB Direct (RDMA) • Higher performance through offloading of network I/O processing onto network adapter • High throughput with low latency and ability to take advantage of high-speed networks (such as InfiniBand and iWARP) • Remote storage at the speed of direct storage • Transfer rate of around 50 Gbs on a single NIC port • Compatible with SMB Multichannel for load balancing and failover Without RDMA With RDMA File Client File Server Application Application App Buffer App Buffer SMB Client SMB Client SMB Server SMB Server SMB Buffer SMB Buffer SMB Buffer SMB Buffer Transport Protocol Driver Transport Protocol Driver Transport Protocol Driver Transport Protocol Driver OS Buffer OS Buffer NIC Driver NIC Driver NIC Driver NIC Driver Driver Buffer Driver Buffer rNIC NIC rNIC NIC iWARP Adapter Buffer Adapter Buffer Adapter Buffer Adapter Buffer InfiniBand

  10. Offloaded Data Transfer (ODX) Offloaded Data Transfer (ODX) Token-based data transfer between intelligent storage arrays • Benefits: • Rapid virtual machine provisioning and migration • Faster transfers on large files • Minimized latency • Maximized array throughput • Less CPU and network use • Performance not limited by network throughput or server use • Improved datacenter capacity and scale Offload Copy Request Write Request Token Successful Write Result Token External Intelligent Storage Array Actual Data Token Virtual Disk Virtual Disk

  11. Unmediated SAN access with Virtual Fibre Channel Access Fibre Channel SAN data from a virtual machine • Virtualize workloads that require direct access to FC storage • Live migration support • N_Port ID Virtualization (NPIV) support • Single Hyper-V host connected to different SANs • Up to four Virtual Fibre Channel adapters on a virtual machine • Multipath I/O (MPIO) functionality Hyper-V host 1 Hyper-V host 2 LIVE MIGRATION Virtual machine Virtual machine Worldwide Name Set A Worldwide Name Set B Worldwide Name Set A Live migration maintaining Fibre Channel connectivity

  13. Storage Automation – Storage Classification

  14. Controlling what people should consume Associate a storage pool and/or logical unit to host group for consumption by hosts/clusters contained in host group Allocate Storage Unassigned Storage Available storage pools Available storage logical units Host groups Assigned Storage

  15. Demo Storage Classification Options in VMM 2012 SP1

  16. Hyper-V over SMB Hyper-V Cluster 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 Hyper-V Hyper-V Hyper-V Hyper-V Hyper-V Hyper-V Hyper-V Hyper-V SQLServer SQLServer SQLServer IIS IIS IIS VDIDesktop VDIDesktop VDIDesktop File Server Cluster File Server File Server Shared Storage

  17. 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 Single 10GbE RSS-capable NIC Multiple 1GbE NICs Multiple 10GbE in LBFO team Multiple RDMA NICs SMB Client SMB Client SMB Client SMB Client LBFO NIC 10GbE/IB NIC 10GbE/IB NIC 10GbE NIC 10GbE NIC 10GbE NIC 1GbE NIC 1GbE Switch 10GbE/IB Switch 10GbE/IB Switch 10GbE Switch 10GbE Switch 1GbE Switch 1GbE Switch 10GbE SMB Server SMB Server SMB Server SMB Server NIC 10GbE/IB NIC 10GbE NIC 10GbE/IB NIC 10GbE NIC 10GbE NIC 1GbE NIC 1GbE LBFO Vertical lines are logical channels, not cables

  23. Configuring Virtual Networking

  24. Merging Physical and Logical in VMM • Logical Network • Models the physical network • Separates like subnets and VLANs into named objects that can be scoped to a site • Container for fabric static IP address pools • VM networks are created on logical networks • Logical Switch • Central container for virtual switch settings • Consistent port profiles across data center • Add port classifications • Consistent extensions • Compliance enforcement

  25. Configuring Logical Networks INTERNET 5 - Create and Assign Gateways 4 – Assign Logical Switch 3 - Create Logical Switches 2 - Define VM Networks 1 - Define Logical Networks Gateway Tenant 1 Tenant 2 Virtual Switch Logical Switch Logical Network Physical Network

  26. Address Pools IP POOLS Assigned to VMs, vNICs, hosts, and virtual IPs (VIP’s) Specified use in VM template creation Checked out at VM creation—assigns static IP in VM Returned on VM deletion MAC POOLS VIRTUAL IP POOLS Assigned to VMs Specified use in VM template creation Checked out at VM creation—assigned before VM boot Returned on VM deletion Assigned to service tiers that use a load balancer Reserved within IP Pools Assigned to clouds Checked out at service deployment Returned on service deletion

  27. Demo Configuring Virtual Networking in VMM

  28. DEMO: Configuring Network Fabric in VMM Define Logical Networks Datacenter Networks (Isolated VLANs) Provider Networks (Virtualized Networks) Define VM Networks One per VLAN or Virtualized Network Create logical Switch Port Classifications & Port Profiles Switch Extensions Assign Logical Switch Host – Add Logical Switch Create and Assign Gateways (Virtualized Networks) The Gateway is how Internet access is provided to isolated tenant VM networks

  29. A Note on Tenant Configuration • Using network virtualization for isolation • NVGRE gateway gives tenants access to outside world • With Gateway • Private cloud: route to local networks • Hybrid cloud: create site to site tunnel • Without Gateway • Use a VM with two NICs • One on isolated network, one on “Internet”

  30. Bringing the Hypervisor Under Management

  31. Bringing Hyper-V Hosts Under Management VMM provides a lot of flexibility in managing Hyper-V hosts and clusters Supports domain and workgroup hosts Windows Server 2008 and 2012 hosts Add hosts through the UI or PowerShell Enables drag-and-drop clustering in the VMM console Provides RBAC for provisioning access to map to our “classes of service”

  32. Bringing VMware Hosts Under Management A few important points to understand Connecting VMM to vCenter does not result in a fundamental change to the datacenter tree Re-arranging and securing vSphere hosts and host clusters in VM does NOT affect security within vCenter Even if you don’t deploy to vSphere in phase 1, this connectivity brings visibility from an asset management perspective
