  5. 5. And it’s not Changing• Mainstream support ended for Windows Server 2003/R2 onJuly 13th, 2010• That means no new products would be developed for it• Extended support ends July 14th, 2015• Don’t bother calling MSFT Support• No more security updates• Logically, no more 3rd party support• The date is not changing
  6. 6. SBS 2003• SBS support cycles depend on component parts• Windows Server 2003/R2: July 14th, 2015• Exchange 2003:• Mainstream support ended April 14th, 2009• Extended support ends April 8th, 2014• That means SBS 2003 support ends next April!!!• No support and SBS 2003 becomes a security vulnerability
  7. 7. SBS 2003 R2• Exchange 2007 support life cycle:• Mainstream support ends: 4/10/2012• Extended support ends: 4/11/2017• However, Windows Server 2003 R2:• Extended support ends: July 14th, 2015• Therefore SBS 2003 R2 support ends July 14th, 2015

  25. 25. Active Directory Administration
  26. 26. Active Directory Administration Agenda• Active Directory Administrative Center (ADAC)• PowerShell History Viewer• AD Recycle Bin• Fine Grained Passwords• DACL• Group Managed Service Accounts• Virtual Domain Controllers
  27. 27. Active Directory Administrative Center (ADAC)• Introduced in Windows Server 2008 R2 and improved inWS2012• Designed for administrators. Common tasks are just there:• Reset a password• Find a user• Different GUI that presents more information• Newer features presented only in ADAC & PowerShell• Performs PowerShell under the hood …
  28. 28. Active Directory Administration Made Easier …• … and cheaper!• PowerShell History Viewer• Finding AD PowerShell difficult to learn?• Open a pane in ADAC to see the PoSH being used• Fine Grained Password Policies• Support demands for special password policies – IT versus the directors!• Simple to do – associate special policies with AD security groups• AD Recycle Bin• Restoring deleted objects is difficult and backup agents are expensive• Right-click and restore single objects or entire OUs!
  29. 29. Benefits• Reduces the learning curve• Increases confidence in scripting• Enhances Windows PowerShelldiscoverability• Graphical user interface supports ActiveDirectory recycle bin functionalityPowerShell History Viewer

  32. 32. • Background• Service need to logon as a user and their passwords should expire• Managed Service Accounts (MSAs) introduced with Windows Server 2008 R2managed their own passwords• Clustered or load-balanced services that needed to share a single security-principal were unsupported– MSAs not able to be used in many desirable scenariosGroup Managed Service Accounts (gMSA)
  33. 33. • Solution• Introduce new security principal type known as a gMSA• Services running on multiple hosts can run under the same gMSA account• 1 or more Windows Server 2012 DCs required– gMSAs can authenticate against any OS-version DC– passwords computed by Group Key Distribution Service (GKDS) running on all Windows Server2012 DCs• Windows Server 2012 hosts using gMSAs obtain password and password-updates from GKDS - password retrieval limited to authorized computers• Password-change interval defined at gMSA account creation (30 days by default)• Like MSAs, gMSAs are supported only by the Windows Service Control Manager(SCM) and IIS application pools– support for scheduled tasks is being investigatedGroup Managed Service Accounts (gMSA)
  34. 34. Use the wizard to deploy a single virtual domaincontroller.Configure additional options for domain controllerclone (for example, name and IP information).Copy source domain controller virtual machineand restart to complete cloning operation.Virtual domaincontroller Clones Rollback Detection• Virtual domain controllers use theunique GenerationID attribute to detectwhen:• Snapshots are applied• A virtual machine is copied• GenerationID changes when an eventaffects virtual machine’s position in time• During startup, the virtual domaincontroller compares the current value ofGenerationID against the value stored inthe directory• A mismatch (rollback event) triggers safevirtual domain controller convergenceVirtualizing domain controllers
  35. 35. Storage
  36. 36. Storage Agenda• iSCSI Target• Storage Spaces• Deduplication• SMB 3.0• Scale-Out File Server
  37. 37. Storage Challenges• Need an iSCSI solution for test, development, demo, andsmall environments• Traditional RAID is expensive and hardware defined• File and archive servers are bursting at the seams• SANs are an expensive requirement for high availability(clusters)• Customers want software defined storage that reuses existingskills and has single admin mechanism across platforms
  38. 38. The iSCSI Target• Turn a server into an iSCSI server• Connect to it just like an iSCSI SAN• Can provide storage for a SAN• Built into Windows Server 2012• A role service• Can be an active/passive role in a Windows Server 2012failover cluster• Brief outage during failover• Great for a lab• System Center 2012 SP1 – VMM includes SMI-S Provider
  39. 39. Storage Spaces• Aggregation of non-RAID disks(such as JBOD): A Storage Space• Think of Storage Pool like a disk group in a SAN• Create virtual disks from a Storage Pool• Think of virtual disks like LUNs or vDisks created from a SAN disk group• Each virtual disk consumes space from physical disk in Storage Pool:• Simple: no disk protection• Mirror: either 2-way mirror or 3-way mirror• Parity: data striped across disks• This is not Windows RAID of the past

  41. 41. Deduplication• De-duplicate at rest data on non-system drive volumes• Cannot be enabled on Cluster Shared Volumes (CSVs)• Greatly reduce storage space used:• File servers• Digital libraries• Archives• Optimization runs on scheduled basis – can also be ondemand
  42. 42. Real World Deduplication ResultsFigures from - Didier Van Hoye, MVP
  43. 43. Improvements in SMB 3.0• SMB 3.0 is a new version of the file sharing protocol• Networking improvements in Windows Server 2012:• SMB Multichannel: Use parallel data streams across a single NIC (RSShardware) and/or across multiple NICs (automatically) with fault tolerance• Think MPIO for file shares• SMB Direct uses Remote Direct Memory Access (RDMA)enabled NICs:• Allows massive file share data throughput with minimal latency and impacton CPU
  44. 44. SMB 3.0 Competes with Block File Access• SMB 3.0 file shares can match if not exceed iSCSI on the samehardware• TechEd Europe 2012 Live Demo:• 1.2 million IOPS from a Hyper-V virtual machine• Over twice the capability of most demanding DB MSFT could find• TechEd North America 2012:• 16 GigaBYTES per second transfer rate• SMB 3.0 is Microsoft’s strategy for data center storage• Software defined and more economic than legacy hardware solutions
  45. 45. SMB 3.0 Use Cases• A file server can provide centralizedstorage for:• Windows Server 2012 Hyper-V – can becentrally managed by System Center 2012 SP1– Virtual Machine Manager• A single store for web servers for many IIS 8.0servers• Even be used for SQL Server (2008 R2 & 2012)database and log files• Does a file server have the uptime?
  46. 46. Scalable & Continuously Available Storage• A new kind of file server cluster:• Scale-Out File Server (SOFS)• A special cluster role• Not for end user file shares• Cluster can use JBOD + Storage Spaces• Traditional SAN storage also supported• Provides more economic softwaredefined storage• Based on tech you know: file shares File Server ClusterNode A Node Bfs1share fs1shareSQL Server

  55. 55. Business Continuity &Disaster Recovery
  56. 56. BC & DR Agenda• Windows Server Backup• Windows Azure Backup• Hyper-V Replica
  57. 57. Backup, DR, and Business Continuity Problems• 3rd party backup solutions are expensive for small businesses• Do you need additional software for just a single server?• Offsite backup is essential but difficult• A replica site?• The receptionist taking tapes or USB drives home on the bus?• Data protection compliance?• What happens if the office burns down or is flooded?• How long can a businesses applications/data remain offline?• DR replication is expensive, inflexible, and often not possible
  58. 58. Windows Server Backup• The built-in backup tool in Windows Server• Basic, local-server-only backup• Uses same Volume Shadow Copy Snapshot (VSS) service as paid-forbackup solutions• Uses the new 64 TB & 4K sector matching VHDX file• Back up to:• Tape• Local drive• Shared folder – does not retain historical backups without intervention• Now supports backing up clusters
  59. 59. Windows Azure Online Backup• A part of Windows Azure Recovery Services• A paid-per-usage backup in the cloud solution from Microsoft• Automated off-site backup• Encrypts your data using your private encryption key beforesending it to the cloud• Microsoft cannot access your data• You really cannot lose that private key – no recovery!• Two solutions:• Upgrade Windows Server Backup to send backup directly to Azure storage• Add-on to System Center 2012 SP1 – Data Protection Manager
  60. 60. Windows Azure Online Backup Scenarios• Backup your data to Azure• Scenario 1: Normal operational restore• Restore lost data to on-premises servers• Scenario 2: Improvised on-premise DR site• Restore lost data to improvised DR site after a disaster• Scenario 3: Improvised DR site in public cloud• Create VMs in a cloud (such as Azure) and restore data to them
  61. 61. Backup for DR• Backup is not great for DR replication• Recovery (RTO) is slow - if at all – and lots of data lost (RPO)• The business is losing money & customer relationships• Might get services back, but will the business recover?• What is needed?• DR site for easy/rapid business continuity• Off-site backup (Windows Azure Online Backup) to restore older data
  62. 62. Benefits• Affordable in-box business continuity anddisaster recovery• Failure recovery in minutes• More secure replication across network• No need for storage arrays• No need for other software replicationtechnologies• Automatic handling of live migration• Simpler configuration and managementNew featureReplicate Hyper-V virtual machines from aprimary site to a replica siteHyper-V role and toolsHyper-VcmdletsHyper-V PSintegrated UIHyper-V Management Moduletracks and replicates changes foreach virtual machineHyper-V role and toolsHyper-VcmdletsHyper-V PSintegrated UIHyper-V Management Modulereceives and applies the changes tothe replica virtual machinePrimary siteCRM virtual machineSQL virtual machineSharePoint virtualmachineExchange virtual machineIIS virtual machine ExchangereplicavirtualmachineCRMreplicavirtualmachineReplicate overWAN linkSMB file shareSend/receivereplica trafficSANR1R2R3P1 P2Replica siteHyper-V Replica
