20. Hyper-V Cluster Design & Backup

21. Why Are We Talking About This?Let’s do some recapAnd discuss some concepts

22. Backup StrategiesThere are 3 types of VM backup you can do with Hyper-V (mix ‘n’ match):Treat the VM as a physical machineBackup everythingLimited usefulness in Hyper-V worldBackup just the changing dataLimited backup traffic and more frequentBackup the VM at the physical storage levelReplace the “bare metal recovery”

23. Backup Like a Physical MachineBackupDPM Agent

24. Backup Just The Changing DataBackupDPM Agent

25. Storage Level Backup

26. BackupVSS ProviderBackup, e.g. DPM 2010CSV LUN

27. Volume Shadow Copy Service (VSS)VSS is used in storage level backupBy default the system (software/Windows) VSS provider is usedSlowVM backup must be “serialized”

28. SerializationGroups VMsDPM can only backup 1 group at a timeRecommended strongly by MS when using system VSS provider for storage level backup“Recovery Point Creation Failed”http://technet.microsoft.com/en-us/library/ff634192.aspxSet registry key valueRun DSConfig.ps1 on a protected cluster hostStore DataSourceGroups.xml at %PROGRAMFILES%\Microsoft DPM\DPM\Config on DPM server

29. Hardware VSS ProviderTry to choose hardware SAN with hardware VSS providerFasterNo need to serializeMust have VSS support for CSV

30. Linux & VSSVSS is a feature of WindowsNo Linux support for VSSCompatible Windows VMs suffer no downtimeTwo optionsStop VM, backup, start VM (requires scripting)Treat the Linux VM as a “physical” serverDon’t backup at storage level

31. Reminder: Redirected I/OExclusive access required to all files for file system operations, such as VSS snapshot.How is that done?CSV coordinator takes over all files.Other host I/O redirected via CSV Coordinator.Also provides storage path fault tolerance.

32. Redirected I/O Illustrated

33. So What?!?!?Backup of 1 VM on CSV causes Redirected I/O for allNeed to consider bandwidth and latency for Redirected I/OThe storage performance of every VM on a CSV will be impactedWhat about active/active multi-site clusters?And we haven’t talked about:Performance (IOPS)Storage level replication policiesStorage fault tolerance

34. Host Design for CSVAll identical OS builds & configurationsAlmost identical hardwareIdentical drive letter (C:\) for %systemdrive%NTLM (NT LAN Manager) must be enabledSMB enabled on each network that may be involved in CSV:Client for Microsoft NetworksFile and Printer Sharing for Microsoft Networks

35. Host NetworkingMicrosoft recommends host as follows:NIC1: Parent partitionNIC2: Virtual machine networkingNIC3: Live Migration (private network)NIC4: Cluster Shared Volume (private network)NIC5 & NIC6: iSCSI (for iSCSI SAN only)Some variationsHP Flex10 for bladesBackup network NICCSV NIC used for Redirected I/OLabel NICs identically on all hosts

36. Specifying CSV NICCSV will automatically use the private (not routed) network with lowest metricYou can force CSV to use a network using PowerShell:CSV NIC labeled as “CSV Network”$n = Get-ClusterNetwork “CSV Network”;$n.Metric = 1033You can reset to automatic metric with:$n = Get-ClusterNetwork “CSV Network”;$.AutoMetric = $true

37. How Many CSVs And How Big?No right answerUse assessment or performance monitoring data to figure out how many VMs in CSVUse IOPS from assessment VS IOPS capabilities of storage from manufacturerConsider VM placementClustered or load balanced VMs should be on different storage“All your eggs in one basket”

38. Backup Impact on CSV DesignDefine backup requirements for VMsStorage level backup once per night/week/month?Data backup?DR replicationMaybe start the on-paper design with one CSVDivide into smaller CSVs to limit impact of redirected I/OBackup policyAffinity/fault toleranceStorage level replicationDon’t forget IOPS

39. Private Cloud Tough To DesignNo assessment dataNothing to P2VNothing to assessYou have no empirical data to size fromPrivate cloud is like a Kevin Costner movie“If you build it, they will come”My tip:Build a pilot environmentDeploy VMs onto different sized VMsBackup each CSVMeasure performance and size accordingly

40. Some Common Approaches to CSVOne CSV per hostOne CSV coordinator role assigned per hostStart with one or two CSVsMonitor storage performance with OpsMgrGrow CSVs as requiredAdd CSV before performance degradesSome do scripting to control Redirected I/O:Live migrated CSV VMs to CSV coordinator hostPerform CSV backup

41. RAID and VM/VHD PlacementRAID 5 gives the most capacityRAID 5 loses maybe 75% of write speedRule of thumb:If you would deploy RAID 10/5 for a physical box for performance, then place the VM/VHD on RAID 10/5 CSVComplicated by disk group/virtual disk in modern SANConsult your storage vendor on best performance VS capacity

42. Fast Track Reference Architecture

43. Cluster/CSV SummaryUnderstand requirements for:BackupDR replicationDesign cluster networking according to best practicesDesign CSV according to requirements for:Backup policyPerformance (IOPS & Redirected I/O)DR storage level replicationFault tolerance

44. Backup SoftwareFor storage level backupYou can use any backup product certified for Windows Server 2008 R2 Hyper-VTest before you buy/useCluster VM location awarenessCSV support For VM level backupAny backup product should work – check with vendor for support of agent in VM

45. Introducing DPM 2010

46. System Center Data Protection Manager 2010Microsoft’s backup solutionPrivate cloud and Dynamic DatacenterBest of breed for protecting Microsoft productsSQL Server, Windows Server, Windows client, Sharepoint, Exchange, Dynamics, and so onLicense as:Server & agent (Client, Std or Ent)System Center Management SuiteEnrolment for Core InfrastructureSCE + DPM + agent

47. Additional DPM 2010 FeaturesImproved storage: auto grow and self healingSharePoint 2010 infrastructure awarenessAutomatic protection of new SP/SQL resourcesSelf-serviceHyper-V CSV supportVM, workload, or bare metal backup and restoreD2D, D2T, and D2D2T backupPowerShell cmdletsSite-to-site replication AKA DPM2DPM4DR

48. Scalability100 Servers, 1000 Laptops, up to 2000 Database per ServerUp to 80 TB per DPM server

49. DPM Backup Is A Little DifferentDeploy disk storage/tape libraryDisk shared by many backup policiesDeploy a single all-purpose agent to protected machineCreate a protection group (backup policy)Defines what you backup/when/retention policyAgent synchronises with DPM serverBlock level changes since last backup are replicated, maybe every 15 minutes, via VSSRecovery points are createdMaybe 3 times/day. You restore from these.

50. DPM RequirementsCheck TechNetToo many variations to include hereDepends on OS and softwarePlease install required patchesD2D storage poolsUse “cheap” SATA diskRule of thumb sizing: 2.5 – 3 times protected disk spaceStorage calculators available for free download

51. Protecting Hyper-V And Workloads

52. Reminder …We have 3 ways we can backup:Storage/hostTreat the VM like a physical machineBackup the changing dataWe need to associate backup policy with virtual machine CSV placementTo control Redirected I/O

53. Scenario 1: ProblemProtect 2 VMsFile1 (File Server):Backup entire VM once/weekBackup file shares 1 time/daySD-SQL1 (SQL Server):Backup entire VM once/dayBackup databases 3 times/dayMinimise impact on network for backup activity

54. Scenario 1: Solution – Part 1Place File1 on CSV1Create protection group for all VMs on CSV1Backup once per weekInstall agent on File1Create protection group: select file sharesSynchronise every 15 minutesRestoration point 1 time per day

55. Scenario 1: Solution – Part 2Place SD-SQL1 on CSV2Create protection group for all VMs on CSV2Backup once per dayInstall agent on SD-SQL1Create protection group: select all databasesSynchronise every 15 minutesRestoration point 3 times per day

56. Site-to-site replication for DR

57. Disaster Recovery ProblemA legal or desired requirement for many organisationsMany solutions, including:Point solution replication: complicated and sometimes delicateStorage replication: expensive hardware/licensing/networking and the domain of big corporations

58. Site-to-Site Replication

59. Site A HostsSite B HostsDPM 2010DPM 2010Storage PoolsStorage Pools

60. Disaster Recovery SolutionWhat is a virtual machine, really?Just a few filesFiles are easy to backup and replicateDPM 2010 backs up Hyper-V VMsDPM server in Site A can replicate storage pools to other DPM server in Site BScheduling and bandwidth throttlingCan restore VMs to alternative hosts/clusters in Site BAdmin console or by (scheduled) script

61. Scenario 2: ProblemBe able to restore File1 and SD-SQL1 to DR site (from Site A to Site B)Recover entire VM and business data to within a few hoursConsolidate vendorsMinimise costsHardware, software, and networkMinimise complexity

62. Scenario 2: SolutionDeploy Hyper-V hosts in Site BDeploy replica DPM server in Site BConfigure protection group:Site A DPM databaseFile1 and SD-SQL1 VMsFile1 shared folders & SD-SQL1 databasesInvocation plan:Recover File1 and SD-SQL1 on Site B hostsRecover File1 shares and SD-SQL1 databases
