QLogic 2600 Series Hyper-V Virtual Server Engine - Manual (Page 17)

The Bottom Line
The improvement factor for memory per VM for Windows Server 2012
Hyper-V—addressing the biggest issue in scaling VMs.
16X
More VMs with Hyper-V, Xeon E5, and QLogic Server Adapters
Fabric-based networks are a fundamental requirement in supporting highly virtualized data centers. Fibre
Channel SANs are the nucleus of the next-generation Windows Server 2012 data center. If your goal is to
increase VM density, Windows Server 2012 Hyper-V combined with the latest generation of servers based on
Intel Xeon E5 processors and QLogic server adapters allows you to more than double the number of VMs per
server while enjoying the same level of performance. Virtualization features like Microsoft vFC and server
adapters from QLogic combine to deliver reliability, performance, and the flexibility necessary to manage the
complexity and risks associated with virtualization projects. Choosing to virtualize Tier-1 data center
applications or increase virtualization densities with QLogic and Hyper-V will enable your businesses to
leverage the built-in architecture of both products to increase availability, improve agility, and overcome
scalability and performance concerns.
Hyper-V delivers improvements on all key virtualization metrics—making I/O performance critical.
