More Virtual CPUs for Scaling Tier-1 Apps with vSphere 5
If you’re concerned about hosng er-1 apps on VMs, the argument about virtualizing er-1 apps is over.
Even agship enterprise applicaons such as SAP, Microso® SQL Server® 2012, and Exchange 2010 have
adopted server virtualizaon as a best pracce. As an example, the CPU, memory, storage, and networking
requirements are well documented by SAP.
More VMs with vSphere, Xeon E5, and QLogic Server Adapters
Fabric-based networks are a fundamental requirement in supporng highly virtualized data centers. Fibre
Channel SANs are the nucleus of the next-generaon vSphere 5.1 data center. If your goal is to increase VM
density, vSphere 5.1 combined with the latest generaon of servers and QLogic server adapters allow you to
more than double the number of VMs per server while enjoying the same level of performance.
vSphere 5.1 will enable your businesses to leverage the built-in architecture of both products to increase
availability, improve agility, and overcome scalability and performance concerns.
vSphere 5.1 delivers improvements on all key virtualizaon metrics—making I/O performance crical.
