Preparing for Disaster
Types of Disasters
RTO vs. RPO
VMware High Availability (VMHA)
VMware Fault Tolerance (FT)
VMware Site Recovery Manager (SRM)
SRM Requirements
Preparing for Disaster
Backing up VMs not enough
Backup data must be moved off-site
Preparation will avoid data loss
Many types of disasters can impact a VM environment
Preparing for Disaster
Virtualization makes backup and DR simple
Hardware independence
Image-based backups
Efficient resource
management – DRS
Automated failover and
replication
Types of Disaster Server failure = HA or FT VM corrupted = Veeam Backup & Replication, restore Datacenter failure = Replicated VM or VMware SRM
RTO vs. RPO
VM vs.
Recovery Point Objective (RPO)Recovery Time Objective (RTO)
VM business data
Amount of elapsed time allowed by business to recover data
Point time to which data must be recover
RTO and RPO negotiated to derive SLA

SRM 4 Requirements
Replication-cable SAN hardware
Site to site network requirements
High bandwidth requirements vSphere and SRM
compatibility vSphere 4, vCenter 4 needed
for SRM
SAN-based Replication
=
=
Hardware replication from SAN array
Continuous Data Protection (CDP)
Hardware and licensing investments
May require entire LUN replication
Frequent replication possible – but very expensive
