What is Site Recovery Manager?Site Recovery Manager Complements vSphere:

simplest disaster protection with auto vCenter discovery and embedded array based replication management

enable frequent non-disruptive testing ensure fast, automated failover

Simplify management of recovery and migration plans

Replace manual runbooks with centralized recovery plans From weeks to minutes to set up new plan

SRM Momentum: Introduced in Q2’ 2008 125,000+ units sold 5,000+ customers 50% annual growth in 2010

SRM5 EnhancementsTechnology

• vSphere Replication

Workflow• Planned

Migration/reprotect/failback

• DR event

User Interface• Completely new UI

Miscellaneous• IPV6• Miscellaneous • API – Protected Side• Dependencies• Resolved Issues


Technology – vSphere Replication

• Virtual machines replicated without advanced array functionality

• Enables replication between heterogeneous datastores

• Replication is managed as a property of a virtual machine

• Efficient replication minimizes impact on VM workloads


vSphere Replication Details

Replication Granularity 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


Replication UI

Select VMs to replicate from vSphere client by right click optionsCan do this on one VM, or multiple VMs simultaneously


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) vSR works at the virtual device layer

• Independent of disk format specifics• Independent of primary-side snapshots• VM is recovered with collapse snapshots• Physical RDMs are not supported

Storage DRS , FT, linked clones, VM templates not supported

Automated failback of vSR-protected VMs not supported yet

Virtual Hardware 7, or later, in the VM is required

Minimum RPO of 15 minutes

Planned Migrations For App Consistency & No Data Loss

Overview

Benefits

Two workflows can be applied to recovery plans: DR failover Planned migration

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

Better support for planned migrations

No loss of data during migration process

Recover ‘application-consistent’ VMs at recovery site

Planned Migration

Site BSite A

Replication

1 Shut down production VMs

2 Sync data, stop replication and present LUNs to vSphere

3 Recover app-consistent VMs

vSphere vSphere


Will shutdown protected VM’s, and

then synchronize

them!

Planned MigrationNew is Planned Migration.


Simplify failback process Automate replication management Eliminate need to set up new recovery

plan

Streamline frequent bi-directional migrations

Automated Failback To Streamline Bi-Directional Migrations

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

Restrictions Does not apply if Site A has undergone

major changes / been rebuilt Not available with vSphere Replication

ReprotectAfter you use planned migration (or DR Event) to migrate to your recovery site, you must reprotect to enable the failback.


FailbackDescription Benefits

• Facilitates DR operations for enterprises that are mandated to perform a true failover as part of DR testing

• Simplifies recovery process after disaster

• “Single button” to failback all recovered VMs

• Interfaces with storage to automatically reverse replication

• Replays existing recovery plans – so new virtual machines are not part of failback

Reverse Replication

Site A (Primary) Site B (Recovery)


FailbackTo failback, you need first to do a migration (DR or Planned), followed by a reprotect. To do an actual failback, the recovery plan is now run againThe recovery plan will now failback the VMs to the original site.


Failback (continued)Reprotect is now almost complete . . .


User Interface EnhancementsThanks to some great UI researchers, designers, and some wonderful customers!

Both sides visible without Linked

Mode!


User Interface (continued)

New icons for shadow VMs


MiscellaneousIPv6

• SRM will support IPv6 for all network links• vSphere Replication will support

communication over IPv6 if underlying ESXi servers support IPv6

IP Customization performance increaseIn guest callouts:

• Since 1.0 you can execute a script that was held on the SRM server, now you can do it inside the guest

• Great for application customization


Miscellaneous – In Guest Callouts/Scripts


APIExisting API on recovery site preservedNew API on both protected and recovery sidesProtected Site API set includes:

List replicated datastores / protection groups / resources / VM

Query the status of protection for a VM or VMs Protect or unprotect one or more VM Status of protection group

Recovery Side API includes: Recovery Plan info Start / cancel, list / answer prompts Get XML representation of historical run of plan Get basic result information of a plan (name, start,

stop, etc.)


DependenciesFunctionality to help manage multitier applications
