10 What s New In Site Recovery Manager 5.0? vsphere Replication Expand DR coverage to Tier 2 apps and smaller sites Automated failback Planned migration Streamline planned migrations (for disaster avoidance, planned maintenance, ) Others More granular control over VM startup order Protection-side APIs IPv6 support 10

11 Key Components Of SRM 5 Required at both protected and recovery sites vcenter Server Virtual Machines VMware vsphere Servers Storage Site Recovery Manager Site Recovery Manager Manages recovery plans Automates failovers and failbacks Tightly integrated with vcenter and replication Choice of replication options vsphere Replication Bundled with SRM Replicates virtual machines between vsphere clusters Storage-Based Replication (3 rd party) Provided by replication vendor Integrated via replication adapters created, certified and supported by replication vendor 11

12 SRM Provides Broad Choice of Replication Options vcenter Server Site A (Primary) Site Recovery Manager Site B (Recovery) vcenter Server Site Recovery Manager vsphere vsphere Replication vsphere Storage-based replication vsphere Replication Simple, cost-efficient replication for Tier 2 applications and smaller sites Storage-based Replication High-performance replication for business-critical applications in larger sites 12

13 vsphere Replication Complements Storage-Based Replication Replication Provider Cost Management Performance vsphere Replication VMware Low-end storage supported No additional replication software VM granularity Managed directly in vcenter 15 min RPOs Scales to 500 VMs File-level consistency No automated failback, FT, linked clones, physical RDM Storage-based Replication Higher-end replicating storage Additional replication software LUN VM layout Storage team coordination Synchronous replication High data volumes Application consistency possible 13

14 Planned Migrations For App Consistency & No Data Loss Planned Migration Overview 1 Shut down production VMs 3 Recover appconsistent VMs Two workflows can be applied to recovery plans: DR failover Planned migration Site A vsphere Site B vsphere Planned migration ensures application consistency and no data-loss during migration Graceful shutdown of production VMs in application consistent state Data sync to complete replication of VMs Recover fully replicated VMs Replication 2 Sync data, stop replication and present LUNs to vsphere Benefits Better support for planned migrations No loss of data during migration process Recover application-consistent VMs at recovery site 14

15 Automated Failback To Streamline Bi-Directional Migrations Automated Failback Reverse original recovery plan Overview Re-protect VMs from Site B to Site A Reverse replication Apply reverse resource mapping Automate failover from Site B to Site A Reverse original recovery plan Site A vsphere Site B vsphere Restrictions Does not apply if Site A has undergone major changes / been rebuilt Not available with vsphere Replication Reverse Replication Benefits Simplify failback process Automate replication management Eliminate need to set up new recovery plan Streamline frequent bi-directional migarations 15

16 Scalability Maximum Enforced Protected virtual machines total 1000 No Protected virtual machines in a single protection group 500 No Protection groups 150 No Simultaneous running recovery plans 10 No vsphere Replicated virtual machines 500 No 16

19 Overall Solution Components vcenter must be 5.0 and licensed and running on each site vsphere must be 3.5 or later and running on each site SRM Server Requires a Windows 64 bit OS. Storage Replication must be on our compatibility list, and have the snapshot or clone technology licensed for SRM tests SRA Storage Replication Adapter is the connection between VMware and the storage environment VRMS vsphere Replication Management Server VRA vsphere Replication Agent VRS vsphere Replication Server ESXi 5.0 Mandatory for vsphere Replication 19

20 Storage Array Integration Storage Replication Adapters (SRAs): Discover arrays Determine which LUNs are replicated Assist in initiating tests, recovery New capabilities in SRAs for version 5.0 include - Reprotect - Synchronization - Planned Migration SRM Server Replication Manager Array Manager SRA Vendor Management Interface Array Manager SRA Vendor Management Interface SRM 5 will require new SRA s Array Array Array SRM Compatibility Matrix: 20

21 21 vsphere Replication

22 vsphere Replication Architecture Tightly Integrated With SRM, vcenter and ESX Protected Site Recovery Site vcenter Server Site Recovery Manager Site Recovery Manager vcenter Server vsphere Replication Management Server vsphere Replication Management Server VSR Agent ESX ESXi vsphere Replication Server ESXi Any storage supported by vsphere Any storage supported by vsphere 22

23 vsphere Replication Details Replication options may be set per Virtual Machine Can opt to replicate all or a subset of the VM s disks You can create the initial copy in any way you want - even via sneaker net! You have the option to place the replicated disks where you want. Disks are replicated in group consistent manner Simplified Replication Management User selects destination location for target disks User selects Recovery Point Objective (RPO) User can supply initial copy to save on bandwidth Replication Specifics Changes on the source disks are tracked by ESX Deltas are sent to the remote site Does not use VMware snapshots 23

24 vsphere Replication UI Select VMs to replicate from within the vsphere client by right-click options Can configure for an individual VM, or multiple VMs simultaneously! 24

25 vsphere Replication 1.0 Limitations Focus on virtual disks of powered-on VMs ISOs and floppy images are not replicated Powered-off/suspended VMs not replicated Non-critical files not replicated (e.g. logs, stats, swap, dumps) VR works at the virtual device layer Independent of disk format specifics Independent of primary-side snapshots Snapshots work with VR, snapshot is replicated, but VM is recovered with collapsed snapshots Physical RDMs are not supported FT, linked clones, VM templates are not supported with VR Automated failback of VR-protected VMs will come later that the initial 5.0 release, but will be supported in the future. Virtual Hardware 7 or later is required for VMs to be protected by VR. 25

26 User Interface SRM s interface is new and able to manage the entire SRM framework from one GUI. Both sides visible without Linked Mode! 26

27 User Interface Site-specific Networking settings for VMs New icons for shadow VMs 27

28 28 SRM Use Cases

29 Use Cases 3 typical Unplanned Failover Preventive Failover Planned Migration Recover from unexpected site failure Full or partial site failure The most critical but least frequent use-case Unexpected site failures do not happen often When they do, fast recovery is critical to the business Anticipate potential datacenter outages For example: in case of planned hurricane, floods, forced evacuation, etc. Initiate preventive failover for smooth migration Graceful shutdown of VMs at protected site Leverage SRM planned migration capability to ensure no data-loss Most frequent SRM use case Planned datacenter maintenance Global load balancing Ensure smooth site migrations Test to minimize risk Execute partial failovers Use SRM planned migration to minimize data-loss Automated Failback enables bi-directional migrations 29 Highly scalable 500 virtual machines

30 SRM Reduces Recovery Risk With Frequent Testing Recovery Risk Traditional Disaster Recovery Recovery Risk DR Test TESTING GAP Lack of confidence in DR process DR Test During the testing gap, organizations can t be sure that they can recover the current IT environment A failover scenario may take days or weeks to complete, leaving the business at extreme risk DR Test Frequent DR Testing Site Recovery Manager DR Test Time Time SRM provides assurance that DR objectives will be met. 30
