Disaster Recovery: Data Replication Presenter Justin Grote En Pointe Technologies Boise VMUG: October 05, 2007 Planning Tips and Tricks to Combat Dwight, the Geek Meteor
Components of a Disaster Recovery Solution Services Platform Where do we bring our services back online? Network Connectivity How do we connect to our DR site after failure? Client Access How do we switch everyone over to the DR site? DR Main Data Protection How do we get our data to the DR site? A B
The Seven Tiers of Disaster Recovery Source: Recovery Specialties ( Data Replication
VMWare: Host Based Data Replication WAN Source VMFS Target VMFS Source: Heavily modified from VMWare Partner Disaster Recovery Presentation, June 2007 Site Failure PRIMARY DR SITE Host (Server) Replication
Host Based Data Replication Advantages Software-Based (Cheap) Quick to Implement No SAN required Flexible, able to add new features as new software versions come out More flexible Disadvantages May require several products VM Only or Product Specific Doesn’t always support differential copy YAV (yet another vendor)
VMWare: Array Based Data Replication WAN or Dark Fiber WAN or Dark Fiber PRIMARY DR SITE Site Failure Source VMFS Target VMFS Source: Heavily modified from VMWare Partner Disaster Recovery Presentation, June 2007
Array Based Data Replication Advantages SAN and recovery all-in-one Block-Level, both physical and virtual data can be replicated with same process Integration with many backup products like Netbackup Disadvantages Can be spendy May or may not quiesce data Lock-In Vendor features vary wildly Requires SAN experience Replication is often not compressed (high bandwidth requirements)
VMWare Site Recovery Manager Newly Announced at VMWorld 2007 Integration with Array (and maybe host?) replication SAN vendors to automate recovery processes and make recovery process easy(ier) Not much info available now, ask again later!
