Server 2016 sneak peek

  1. 1. Windows Server 2016 “sneak peak” THOMAS MAURER MVP Hyper-V itnetx gmbh Blog: www.thomasmaurer.ch Twitter: @thomasmaurer MICHAEL RUEEFLI MVP Cloud & Datacenter Management itnetx gmbh Blog: www.miru.ch Twitter: @drmiru
  2. 2. Session Objectives Get a “sneak peak” of Windows Server 2016 on: • Software defined Storage, the next level • Hyper-V • Automation • Nano Server
  3. 3. Software defined Storage (current) I can’t implement a Microsoft Storage Solution because… “Replication on Storage-Level is missing” “I wanna do Hyper- Converged” “I don’t trust Microsoft doing Storage”
  4. 4. Software defined Storage v3.0 • Volume based Storage Replication (sync / async) • Storage Spaces direct • Hyper-Converged • ReFS • Distributed Storage QoS • Deduplication Enhancements
  5. 5. Current SDS with Server 2012 R2 (1 / 2) SoftwareDefinedStorageSystem • Scale-Out File Server • Cluster Shared Volumes • Storage Spaces • Hardware Shared JBOD Storage
  6. 6. Storage Spaces Direct logical View Software Defined Storage System Storage Node Storage Node Storage Node Storage Node Storage Pool Storage Space Virtual Disks Scale-Out File Server FileServerShare Cluster Shared Volumes C:ClusterStorage SMB3 Storage Network Fabric Software Storage Bus • Local Storage (inline or JBOD) • Support for SATA and NVMe SSD • Fault Tolerance to disk and node failures • Hyper-V VM Storage • Backup Storage • Converged • Hyper-converged
  7. 7. Scenarios Hyper-converged Converged (Disaggregated) Compute and Storage resources together Compute and Storage scale and are managed together Typically small to medium sized scale-out deployments
  8. 8. Storage Spaces Direct - Data Placement • Virtual Disks • Virtual disks consists of extents • Extents are 1GB, so a 100GB virtual disks has 100 extents • Scale-Out • Extents are distributed across disks and servers • Rebalancing occurs if adding more nodes • Resiliency • A 2nd copy of an extent is placed on a different server • A 3rd copy of an extent is placed on yet another server Server EServer B Server C Server DServer A A A’ A’’B B’ B’’C C’C’’
  9. 9. Storage Spaces Direct: Requirements (TP2) • 4 up to 12 Storage Nodes • 10 Gbps RDMA (RoCE) • Min. 1 SSD per Node • Supported HW Model (VMs for LAB)
  10. 10. Storage Spaces Direct Development Partners Quanta D51PH HP Apollo 2000 System Dell PowerEdge R730xdCisco UCS C3160 Rack Server Intel® Server Board S2600WT-Based Systems Lenovo System x3650 M5 Fujitsu Primergy RX2540 M1
  11. 11. DEMO STORAGE SPACES DIRECT
  12. 12. Storage Replica BCDR Synchronous or asynchronous Cluster <-> Cluster Server <-> Server Microsoft Azure Site Recovery orchestration Stretch Cluster Synchronous stretch clusters across sites for HA Benefits Block-level, host-based, volume replication End-to-end software stack from Microsoft Works with any Windows volume Hardware agnostic; existing SANs work Uses SMB3 as transport
  13. 13. NODE1 in HVCLUS SR over SMB3 NODE3 in HVCLUS NODE2 in HVCLUS NODE4 in HVCLUS ManhattanDC JerseyCityDC Stretch Cluster • Single cluster • Automatic failover • Synchronous
  14. 14. Cluster to Cluster • Two separate clusters • Manual failover • Synchronous or asynchronous NODE1 in FSCLUS NODE2 in DRCLUS NODE3 in FSCLUS NODE4 in DRCLUS NODE2 in FSCLUS NODE4 in FSCLUS NODE1 in DRCLUS NODE4 in DRCLUS SR over SMB3 ManhattanDC JerseyCityDC
  15. 15. Server to Server • Two separate servers • Manual failover • Synchronous or asynchronous SRV1 SR over SMB3 SRV2 ManhattanDC JerseyCityDC
  16. 16. Storage Replica: Requirements (TP2) • Any volume (SAS, SAN, iSCSI, Local) • <5 ms round trip between sites for synchronous mirror (at 1472 non-fragmented bytes packet size) • RDMA NICs • Identical size for source / target volume • SSDs for log disks recommended • Identical physical disk geometry
  17. 17. DEMO STORAGE REPLICA
  18. 18. ReFS (Resilient File System) • New Default FS for VM Workloads • Metadata Checksums • User Data Checksums • Checksum Verification • Autohealing of detected Corruption • Lightening fast VM Checkpoint creation / merging • Ultrafast fixed VHDX creation • Autohealing of detected Corruption
  19. 19. DEMO RESILIENT FILESYSTEM
  20. 20. Hyper-V • Huge number of new features • Cluster Rolling Upgrades • Online Resize Memory • Hot add / remove Network Adapters • Software Defined Networking / Network Controller • Improved Shared VHDX, Hyper-V Manager, Backup… • Security • PowerShell Direct
  21. 21. Challenges in protecting high-value assets
  22. 22. Shielded VMs Host Guardian Service Spotlight capabilities Shielded Virtual Machines can only run in fabrics that are designated as owners of that virtual machine Shielded Virtual Machines will need to be encrypted (by BitLocker or other means) in order to ensure that only the designated owners can run this virtual machine You can convert a running Generation 2 virtual machine into a Shielded Virtual Machine
  23. 23. PowerShell Direct to Guest OS • You can now script PowerShell in the Guest OS directly from the Host OS • No need to configure PowerShell Remoting • Or even have network connectivity • Still need to have guest credentials • Enter-PSSession –VMName “VM01” –Credentials $Cred • Get-Service –VMName “VM01” –Credentials $Cred
  24. 24. Network Adapter Identification • You can name individual network adapters in the virtual machine settings – and see the same name inside the guest operating system. • PowerShell in host: • PowerShell in guest: Add-VMNetworkAdapter -VMName "TestVM" -SwitchName "Virtual Switch" -Name "Fred" -Passthru | Set-VMNetworkAdapter -DeviceNaming on Get-NetAdapterAdvancedProperty | ?{$_.DisplayName -eq "Hyper-V Network Adapter Name"} | select Name, DisplayValue
  25. 25. Remote FX • Support for OpenGL 4.4 and OpenCL 1.1 API • Larger dedicated VRAM and configurable VRAM.
  26. 26. DEMO HYPER-V
  27. 27. Automation
  28. 28. Automation vNext • Hybrid Worker • Graphical Authoring • Linux Support (DSC / SSH) • Azure DSC Pull Server • As Part of Azure Stack for “on premises”
  29. 29. And last but not….. THE (data)-BUS IS BACK!
  30. 30. DEMO AUTOMATION VNEXT
  31. 31. Nano Server • Headless Shit
  32. 32. • • • Voice of the Customer (-> us!)
  33. 33. Security Impact
  34. 34. I want just the components I need and nothing more
  35. 35. IT Pro Server Journey Windows NT to Windows Server 2003 Windows/ WindowsNT Server Roles/Features Windows Server 2008 and Windows Server 2008 R2 Server Core Full Server Windows Server 2012 and Windows Server 2012 R2 Server Core Minimal Server Interface GUI Shell Windows NT / Windows Server 2003 Windows Server 2008 Windows Server 2008 R2 Windows Server 2012 Windows Server 2012 R2
  36. 36. • Azure • Patches and reboots interrupt service delivery • (*VERY large # of servers) * (large OS resource consumption) => COGS • Provisioning large host images competes for network resources • Cloud Platform System (CPS) • Cloud-in-box running on 1-4 racks using System Center & Windows Server • Setup time needs to be shortened • Patches and reboots result in service disruption • Fully loaded CPS would live migrate > 16TB for every host OS patch • Network capacity could have otherwise gone to business uses • Reboots: Compute host ~2 minutes / Storage host ~5 minutes Microsoft Cloud Journey
  37. 37. We need server configuration optimized for the cloud
  38. 38. • A new headless, 64-bit only, deployment option for Windows Server • Deep refactoring focused on • CloudOS infrastructure • Born-in-the-cloud applications • Follow the Server Core pattern Nano Server - Next Step in the Cloud Journey Server Core Server with Local Admin Tools Basic Client Experience Nano Server
