We've answered your questions around deploying Skype for Business. Our testing results are published in the latest Skype for Business Reference Architecture, Microsoft Skype for Business, Standard Edition, 2500 Users – Virtual and Physical Deployment Use Cases.

Questions. We all get them every day. For some, we answer with our opinion. For others, we need to say “I don’t know, let me find out.” And for others we can clearly say, “I have the answer!”

This is exactly why the HPE Skype for Business engineering team embarked on a multi-month project to answer the question: “Which is the best for Skype for Business - Physical or Virtual?” You'll find our answers in the latest Skype for Business Reference Architecture, Microsoft Skype for Business, Standard Edition, 2500 Users – Virtual and Physical Deployment Use Cases.Reference Architecture_Skype_QA_blog.jpg

For Skype for Business administrations, you know that Skype for Business Server 2015 is a more network-dependent application. Keeping this in mind, the Reference Architecture discusses the value that features such as SR-IOV adds to the virtual deployment of Skype for Business Server 2015. HPE also looked at the benefit HPE Intelligent Resilient Fabric (IRF) and HPE Network Optimizer SDN Application for Microsoft Skype for Business Server 2015 adds to both physical & virtual Microsoft Skype for Business Server 2015 deployment.

Why we tested Skype for Business on ProLiant DL380 Gen9 Servers

HPE Engineering utilized HPE ProLiant DL380 Gen9 Servers for the testing. Our engineers selected ProLiant because performance, expandability, reliability, serviceability and near-continuous availability are key requirements for any real-time communication environment such as Skype for Business Server 2015. Additionally, the HPE ProLiant DL380 Gen9 Server leverages Intel’s latest E5-2600 v3 series which support the Intel Virtualization Technology for Directed that helps end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments

The testing performed and documented in the Reference Architecture is designed to validate that the network, storage, CPU and memory subsystems can support the selected workload in normal operations, both physical & virtual Microsoft Skype for Business Server 2015 deployment. The testing was done using the Skype for Business Server 2015 Stress and Performance Tool and Microsoft Lync Server 2013 Persistent Chat Resource Kit ChatStress Tool. Results of the testing shows that when compared to a physical deployment of Skype for Business Server 2015, a virtual deployment consumes more compute resources at the host hypervisor layer. HPE’s recommendation is that you size the virtual deployment appropriately so that all key performance metrics for SfB are within the required threshold.

Use our Skype for Business Sizer Tool too

As a companion to the Reference Architecture, HPE has Skype for Business Sizer Tool. The Sizer is a downloadable application allowing the end-user to customize input and receive an exact specification for Skype for Business. The Sizer generates bills of material for your specific infrastructure.

HPE has worked with many customers in financial services, manufacturing, pharmaceuticals, healthcare, insurance, and the public sector all over the world to help plan and deploy Skype for Business.
