VMware vSphere Essentials Plus* adds live migration high application availability and data protection for a
complete server consolidation and business continuity solution for the small office IT environment. Both
editions are all-inclusive packages that enable many application workloads to be virtualized and consolidated
onto three physical servers running vSphere and to be centrally managed. VMware vSphere also comes in
Standard, Enterprise and Enterprise plus editions that are appropriate for larger data center or cloud
deployments:
Figure 2 - VMware vSphere* Versions
Standard: Provides an entry solution for basic consolidation of applications to greatly reduce hardware
costs while accelerating application deployment.
Advanced: Provides a strategic consolidation solution that protects all applications against planned and
unplanned downtime to provide superior application availability and data protection.
Enterprise Plus: Includes the full range of vSphere* features for transforming datacenters into
dramatically simplified cloud computing environments that can provide the next generation of flexible,
reliable IT services to their businesses.
vCenter Server* Foundation: Provides users the benefits of vCenter Server*, but is designed to serve
the needs of a smaller IT environment with the ability to manage three or fewer physical server hosts
running vSphere*.
Maximize Virtualization Benefits
Intel is also building a better physical platform with unique hardware assist features to enhance the virtual
datacenter and help tame server sprawl. The Intel® Xeon® processor 5600 series, built on Intel®
microarchitecture, codenamed Westmere, expands the benefits of virtualization with innovations that boost
performance, increase consolidation ratios, and enable servers of different generations to be combined in
the same virtualized server pool, improving virtual machine failover, load balancing, and disaster recovery
capabilities.
Intel® Virtualization Technology (Intel® VT) continues to offer investment protection and infrastructure
flexibility with multigeneration VM migration across the full range of 32-bit and 64-bit configurations,
enabling bigger VM pools.
Intel® Virtualization Technology for Connectivity (Intel® VT-c) provides hardware-assisted I/O that
accelerates network performance and simplifies VM migration.
