VMware Virtualization Basics
Software tied to hardwareSingle OS image per machineOne application workload per OSInflexible, costly infrastructure
Before Virtualization: After Virtualization:
Virtualization Layer is a software abstraction that allows operating systems and applications to run on virtual hardware that is distinct from the physical hardware
Key Properties of Virtual Machines
PartitioningRun multiple operating systems on one physical machineDivide system resources between virtual machines
Key Properties of Virtual Machines
IsolationFault and security isolation at the hardware levelAdvanced resource controls preserve performance

VMware Lowers Cost of Clustering
Cluster-in-a-boxProtects against operator error, application and operating system crashes
Cluster-across-boxesProtects against operator error, application and operating system crashes, and hardware failure
Cluster between physical and virtual machinesLow-cost N+1 redundancy with a great reduction in hardware requiredUse MSCS clustering for automated failover between physical and virtual machines
Options for Disaster Recovery
Physical to PhysicalToday’s scenario without virtual infrastructureRequires identical disaster recovery site
Physical to VirtualReduces cost, improves time to recovery, and increases flexibility
Virtual to VirtualGreatest flexibility, lowest cost, best time to recovery
Result: 16.5 minutes to failover!
Disaster Recovery Customer Scenario #1
Disaster Recovery Customer Scenario #2
Multiple physical machines to access the same storage
Multiple ESX Servers see the same VMFS volumes to provide:
Workload balancing via easy VM relocationHigh availability using clustered applicationsRapid provisioning using a Template Repository
Native MPIO multipathing support provides I/O-channel redundancy
Maintains VM access to virtual disk files in case of HBA or SAN-path failure

Combining ESX Server with Storage Area Networks
SAN-based Boot Support for ESX Server
Advantages of booting ESX Server off the SAN:
Improved availability—Boot device protected on networked storageImproved flexibility—Servers can be easily replaced in case of failuresReduced complexity—Leverage best practices for backup and restore

Local Replication with ESX Server
Physical-to-VirtualReduce total cost of ownership by consolidating backup servers onto one ESX Server
– Virtual Machines on the backup / mount ESX Server can access the replicas to back up application data
– Supported for application data and RDMs Production servers

Remote Replication with ESX Server
Physical-to-Virtual: Reduce total cost of ownership at the secondary site by consolidating servers
– ESX Server at the secondary site can be used for remote backup, or as disaster-recovery servers
