Limitations of Managing ESX with Microsoft SCVMM

“Microsoft hopes that its customers, already implementing the competing hypervisor [ESX], stop using VirtualCenter and turn to SCVMM 2008 for any task. Unfortunately this goal seems hard to achieve considering some limitations that plague this first attempt.”

You can’t afford to risk your datacenter on an unproven offering


VMware: Proven Solution, Unrivaled Customer Success

130,000+ VMware customers

100% of Fortune 100

98% of Fortune 1000

94% use VMware in production

70% use VMotion in production

65% VMware as the default/ most new production servers

The World’s Most Successful Companies Run VMware

(hundreds of customer stories on www.vmware.com)

http://www.vmware.com/

But what about cost?VMware solutions are a lower cost

per application than other so-called “free” virtualization offerings.

What is Cost per Application VM density is critical in a virtual environment

Physical World Virtual World

1:1 relationship between applications and hardware

Relevant cost metric = upfront licensing

Many:1 relationship between applications and hardware

Relevant cost metric = cost/application

VMware Density Advantage Why VMware’s superior technology makes it a less expensive solutionMemory OversubscriptionMore efficient use of physical RAM by reclaiming unused physical memory and consolidating identical memory pages among VMs on a host.

Direct Driver ModelVMware ESX can achieve very high I/O throughput and can handle the I/O requirements for more VMs simultaneously requesting hardware resources.

Support for Large Memory Pages and Nested Page TablesOptimize memory access and can provide substantial performance benefits for mission critical, memory-intensive applications, can reduce CPU resource consumption by up to 15%.

DRS with Resource PoolsDynamically load balance VMs across a cluster so applications get required resources when they need them -a “safety net” that lets administrators run individual servers at higher utilization levels while meeting service level agreements.

High Performance “Gang” Scheduler Can account for CPU and I/O needs of virtual machines by dynamically allocating more resources and larger processor timeslices to VMs.
