Comparison of cost of virtualization deployment per virtualized - VMware Vs Microsoft06-19-13
VMware Cost-Per-Application Calculator Results Report
The VMware Cost-Per-Application Calculator compares the cost of virtualizing applications on VMware
vSphere 5.1 versus other commodity virtualization offerings, like Microsoft Windows Server 2012
(Hyper-V) or Citrix XenServer 5.6. The calculator implements an accurate and simple methodology
(Cost Per Application) to compare the actual capital cost of running applications in a virtual
infrastructure.

Comparison of cost of virtualization deployment per virtualized - VMware Vs Microsoft06-19-13
Executive Summary
The unique features and architectural design of VMware vSphere 5.1 allow you to run many more
applications per server (higher VM density) at an acceptable level of performance than other
virtualization solutions. In our own testing and from reviews of our customers, we have seen VMware
vSphere 5.1 users commonly achieve 50-70% higher VM density per host than with Microsoft Hyper-V,resulting in a 20-30% lower cost per-application.
Based on your inputs, the cost-per-application to virtualize 5 applications using VMware
vSphere 5.1 Enterprise Plus Edition is $19,162 29% higher1 than with Microsoft Hyper-V and
System Center 2012.
VMware also offers other editions of vSphere besides the one you chose, and each offers a different
level of functionality to meet specific business requirements. For a complete comparison with
Microsoft Hyper-V + Systems Center, we have included other VMware vSphere 5.1 editions in thegraphs and table below. The VMware vSphere 5.1 edition you have selected is highlighted for easy
reference.
Graph 1 Comparison of the Cost-Per-Application to Virtualize 5 Applications
VMware vSphere 5.1 can deliver a much lower cost per application
than Microsoft's virtualization offerings
1 Assumes that a VMware ESXi host can run 20% more applications than a Microsoft Hyper-V host
Note: The comparison graph assumes a new deployment, i.e., no pre-existing VMware vSphere or VMware
Infrastructure 3 deployment. For new deployments in small office settings, VMware offers multiple low cost
bundles -- vSphere Essentials Plus, vSphere Standard and Enterprise Acceleration kits, vSphere Enterprise
Plus Acceleration Kit -- that include licenses for vSphere and vCenter Server for centralized management.

Top reasons why VMware vSphere 5.1 enables greater VM density
Due to its advanced technologies and architecture, VMware vSphere 5.1 makes it possible to
successfully run more applications per host (physical server) and to achieve higher VM density than
other solutions. Consequently VMware vSphere 5.1 delivers a lower cost per application than Microsoft
Windows Server 2012 (Hyper-V) + Systems Center. The most significant reasons why VMware
vSphere can enable a higher VM density per host include the following:
1. Memory Oversubscription VMware ESXi makes more efficient use of physical RAM by
reclaiming unused physical memory allocated to particular VMs (think of it as de-duplication for
10 / 11
7/28/2019 Vmware Competitive Calculator Report 06-19-13!14!40-56
11/11
Comparison of cost of virtualization deployment per virtualized - VMware Vs Microsoft06-19-13
memory) and consolidating identical memory pages among VMs on a host. Both functions let
ESXi oversubscribe memory on a server with minimal impact to performance. This memory
oversubscription is no different than oversubscribing the CPU and network on a virtual host. Other
solutions, such as Microsoft Hyper-V and Citrix XenServer, are beginning to implement memory
management techniques, but none use multiple methods for managing memory like VMware
ESXi.
2. Direct Driver Model VMware optimizes device drivers for virtualization and places them directlyin the ESXi hypervisor. By giving VMs direct and fast access to the hardware VMware ESXi can
achieve very high I/O throughput and can handle the I/O requirements for more VMs
simultaneously requesting hardware resources. Other hypervisors, such as Hyper-V and
XenServer, use an indirect driver model that leverages the generic Windows or Linux device
drivers located in management OS (Windows Server 2012 Parent Partition or Linux Dom0). The
indirect architecture single threads the I/O requests from all VMs through a single channel into
the Parent Partition/Dom0 instance of Windows Server/Linux, forcing the VMs to fight over
resources in the operating system. This creates an I/O bottleneck that reduces the I/O throughput
Hyper-V and XenServer can achieve; as more VMs are run on the same host, the I/O bottleneck
gets worse. The indirect driver model also makes every VM reliant on third-party device driversthat have achieved only basic WHQL certification Microsoft does not require device drivers used
with Hyper-V to be tested with a virtualized environment. That makes all your Hyper-V VMs
dependent on the component of Windows known to be its weakest link the device drivers.
3. High Performance "Gang" Scheduler VMware designed and optimized the ESXi process
scheduler to handle the resource requirements of many heterogeneous VMs. Other hypervisors
use the generic process scheduler of general purpose operating systems. These were not
designed for virtualization nor do they meet the special needs of multiple VM workloads. Generic
process schedulers, like used with Hyper-V and XenServer, were designed to fulfill different use
cases, such as providing an effective user interface experience. Because of its reliance on theWindows scheduler, Hyper-V gets hit by performance limits at levels far lower than those of
VMware ESXi and can run fewer VMs per host than VMware ESXi. By comparison, the
architecture of the ESXi "Gang" scheduler is optimized for virtualization. It can dynamically
account for the CPU and I/O needs of virtual machines by dynamically allocating more resources
and larger processor timeslices to VMs. The ESXi scheduler is also better at handling
multiprocessor VMs (also known as SMP VMs) by supporting near-synchronous coscheduling of
the virtual CPUs within a single multiprocessor VM.
4. DRS with Resource Pools VMware Infrastructure can dynamically load balance VMs across a
cluster so applications get required resources when they need them. This reallocation ofresources happens automatically and without service discontinuity, based on service levels set by
the application owners. DRS, with Storage and Network I/O controls, is essentially a safety net
that lets administrators run individual servers at higher utilization levels while meeting service level
agreementseven when spikes occur. DRS lets usage spikes that might overwhelm a single
server be leveled across many servers in a cluster with no interruption to the end user.
Bottom Line:
With these and other product advantages VMware customers report that they can achieve 50-70%
higher VM density per host than with Microsoft Hyper-V. This results in a 20-30% lower
cost-per-application on average. However, VMware vSphere 5.1 will also provide a lower
cost-per-application than Microsoft Hyper-V even at a similar VM density.
