WSV205: Windows Server 2012 Overview

Michael Leworthy, Senior Product Manager (Microsoft)

Top Benefits of Windows Server 2012

  • Comphrehensive Cloud Platform – Complete virtualization platform, industry leading scalability, business continunity in a box.
  • Cost savings and increased efficiencies – Reduced storage costs with storage spaces with other storage enhancements. Increased server/administrator¬† ratio through Windows PowerShell and multi-machine management. 10x improvement in PowerShell cmdlets (over 2400)
  • Support for a modern work style – Simplified VDI management, optimize branch office WAN bandwidth usage

  • Server Virtualization (Hyper-V)
    • Hyper-V network virtualization – Migrate IPs across subnets and into a cloud provider. IP address translation, encapsulation.
    • Shared-nothing live migration – Live migrate outside of a cluster and with no shared storage. Only an ethernet cable is needed.
    • Massive scale- Up to 320 logical processors and 4TB of RAM per physical server.
    • Cluster enhancements – Previously serial migration; now simulatneous migration with no hard limit (just limited by bandwidth). Affinity and anti-affinity clusters. Fully supports encrypted storage for clusters.
    • Hyper-V replica – Disaster recovery
    • Hardware offloading – IP offloading, storage offloading
    • Virtual Fibre Channel –
    • Guest NUMA support
    • Runtime memory configuration – Adjust memory profile during runtime
    • Hypoer-V network switch – Extensible switch like the Nexus 1000v
  • Hyper-V Demo
    • Demod concurrent Live Migration
    • VHDs can be storage on SMB shares and they perform nearly like direct attached storage
    • Up to 1TB of RAM per VM
    • Up to 64 vCPUs per VM
    • Processor compatibility (EVC mode) for migration between Intel and AMD
    • VHDX format, up to 64TB per volume, plus 4K disk support
    • Network adapter hardware acceleration options (SR-IOV, IPsec offload, VMQ)
    • NIC teaming at the VM level (teaming within the NIC) or at the physical level
    • Live migrate a VM, and if the switch configuration differs, it will present an error and a wizard to select the new network name and continue the migration.
    • Hyper-V Replica – Supports replication to a provider using certificates, or internally using HTTP and kerberos.Out of the box functionality.
  • Management and Automation
    • Multiserver management
    • Role and feature deployment
    • Integrated console
    • 2,400 PowerShell cmdlets
    • Disconnected sessions
    • Windows PowerShell Workflow
    • Windows PowerShell web Access
    • Windows PowerShell ISE (Integrated Scripting Environment)
    • Script Sharing between servers
    • Syntax and Simplification and Intellisense
  • Management and Automation Demo
    • Manage multiple servers at one time. Good for up to 30-50, but no hard limit
    • Create a server group and add servers. You can then manage and monitor them as a group. Metro-style overview.
    • Multi-server volume manager- View volume sizes, extend volumes, dedupe rates, etc.
    • GUI is context aware – Right click on a server and it only lists the tools/options relevant to that server.
    • PowerShell ISE – Intellisense for ease of scripting
    • PowerShell web access
    • GUI is now a role you can turn off and on. Flip between server core and desktop mode. Reboot required.
  • Storage Features
    • Storage Spaces – Virtual disk infrastructure using JBOD
    • File system improvements – Greatly enhanced self-healing
    • Thin provisioning and trimming
    • Cluster shared volume – Supports encryption
    • SMB 3.0 for workloads – Support Hyper-V and SQL server
    • Offloaded data transfer (ODX) – SAN offloaded data transfer
    • Transparent failover – Ensures planned or unplanned downtime doesn’t impact SMB shares. Active/active file shares.
    • NFS support – ODX, transparent failover support
    • iSCSI target
    • Storage management
  • Storage Demo
    • Storage pool – Create with JBOD disks, supports hot spare
    • Inbuilt resiliency – simple, mirror, parity
    • Thin or fixed volume allocation
    • Instantly add more storage to a pool
    • Instantly expand volumes as needed
    • Enterprise reliability an resiliency
    • SMB scale-out – Five file share profiles (3 for SMB, 2 for NFS)
  • Web and application platform
    • Website density and multitenancy
    • Application initialization
    • Dynamic IP restrictions
    • CPU throttling
    • NUMA-aware scalability
    • Centralized SSL management and certifcate updating. Cut and paste certs as if they were files.
    • “Just works” with PHP and node.js
    • Embracing web standards
    • Application symmetry
    • Community development platform
  • IIS Demo
    • Able to CPU throttle a IIS worker process
    • Throttle under load option – Limits IIS CPU usage if server is otherwise busy
  • Network features
    • NIC Teaming
    • Network virtualization
    • DHCP server failover
    • SR-IOV
    • Resource metering
    • Dynamic virtual machine queue
    • IP Address Management (IPAM) – Centralized into a single view
    • Quality of Service (QoS) and bandwidth throttling
    • BranchCache
    • SMB Direct and multichannel
  • Network Demo
    • Realtime bandwidth control with PowerShell cmdlet
    • Enhanced VM resource stats – calculate the cost of a VM based on I/O, CPU
  • Security and access
    • Dynamic Access Control
    • Classification
    • DirectAccess
    • Simpler deployment of Active Directory via powershell
    • Domain name security extensions
    • Active Directory virtualization – No longer a problem
    • Active Directory cloning – Drag and drop a new DC
    • Kerberos constrained delegation – E.g. Setup a jumpbox to manage certain servers
    • Private virtual LAN (PVLAN)
    • Multitenant security and isolation
