“….deploying Windows Server 2012 has the potential to provide solid ROI..the enablement of software defined networking with Network Virtualization..” – Forrester Consulting study, Feb 2013

Windows Server 2012 - An ideal migration path to tomorrow's world of private and public clouds…

I expect to reduce storage costs by 10 times and server costs by 50%.

— Dan Smith, Deputy CIO, Marquette University

We decided to avoid paying VMware $1.75M (U.S.) in licenses and go with Windows Server 2012 and Hyper-V to build a private cloud model for our regional datacenters.— Studio Moderna, Slovenia

“The ability to virtualize network traffic without reengineering our base physical network infrastructure is huge,” Bourassa — Alan Bourassa, CIO, EmpireCLS, on their use of Hyper-V Network Virtualization

I‘ve been a huge advocate for VMware. With Windows Server 2012 and the latest version of Hyper-V, all of that changes. — Justin Apps, Head of Enterprise Architecture, about how they

improved identity and access management with Windows Server 2012

“Windows Server 2012 is built deep in the cloud... You end up with a solution set that has the capability of doing the kinds of compute scenarios that customers will want to do in the next few years...we think it's a great product." — Al Gillen, IDC

NVGRE Optimized VNeX™ Network VirtualizationOffload Technology Performance Optimizations

Emulex has announced planned support for VNeX™ Network Virtualization Offload Technology optimized to improve the performance of NVGRE

NVGRE optimized offloads increase network throughput by 130%

– These are early test results– CPU utilization is critical

Benefits– Improved VM density– Better network throughput– Lower CPU utilization for NVGRE

Note:– Results are illustrative and based on

early engineering testing and will vary based on VM density, CPU utilization, and other configuration parameters.
