New Trends for Disaster recovery – BC31
Storage VMotion – move VM disks without downtime!
Site Recovery Manager
DR Pain points
- lack of reliable plan
- can’t meet RTO or RPO reqs
- expenses for hardware at DR site
VI3 improves DR
- RTO / Cost / Reliability
- Failover / Planning / testing
- isolate network for live testing
- Hdw independence / encapsulation / boot from san / drs and resource pools / snap shots & vlans
- instant repurposing
Site recovery Manager – DR workflow automation product
Objectives:
- increase DR plan coverage
- reduce recovery time of all servers – hours not days
- improve success rate – 100% of servers
- assurance DR plan works
How does it ?
- automate dr failover
- propogate vcbs into dr plan
- enable regular non disruptive testing
- manage vi3 and storage replication
- set up networking – changing ip addresses
- QOS
- implement change control
How it works
- plugs in to VC2
Technical Objectives
- Setup: integrate with storage replication to determine wich VMs are replicated
- Failover: auto promote LUNs at DR site
- test: auto LUN snap shots
- compatible: FC or iSCSI modules for OEMs
Workflow 1: Site prep
- pre-program the DR response
- shutdown vms
- startup order
- VM recovery steps
- repitition
- mirror design and layout at DR site
- port groups / vswitch
- volume folder
- resource groups
- change control
- role based access
- instant changes
- audit trails
- exported as needed
Workflow 2: Failover
- Automate powering on of vms
- handle networking at remote site
- vlans, port groups, ip addresses – srm changes ip addresses, subnet, dns, port group (vlan)
- script dns updates – srm exports a list of changes and you can create script to make changes in dns
- ensure qos at time of DR – resource pools – auto shutdown of VMs
Workflow 3: Test
- non disruptive testing
- isolate storage i/o
- isolate network traffic
- report on testing metrics and success
Create Protection Groups of VMs which map to LUN groups
Recovery Plans prioritize Protection Groups and startup of the VM members. Different recovery plans can be created with different permissions for different business units.
