Scaling a Virtualized SAP Workload from Small to Large ESX hosts – a new whitepaper…

Scalability and performance of SAP transactions in a virtual environment is important for customers in situations where they experience increasing workloads to accommodate additional users and new parts of the business that migrate to SAP during a phased deployment. Part of this growth can include a scenario where a customer starts with smaller ESX hosts and during hardware refresh cycles acquire newer larger servers. It would be reassuring to know that as the SAP workload grows and is moved to the newer larger ESX hosts, scalability of the workload is not compromised. This is demonstrated in the following paper that documents a proof of concept conducted by HP, Intel, SAP, SUSE, and VMware:

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e0eb1f0b-15b6-2e10-69ad-f5f54c43222c?QuickLink=index&overridelayout=true

The paper shows how a three-tier SAP workload linearly scales (better than 90 percent of full linear scalability) from a two-socket Intel Xeon processor 5600 series-based server to an eight-socket Intel Xeon processor 7500 series-based server. The final large configuration consisted of an 8-way, 128 GB virtual machine running a MaxDB database and Central Instance and fourteen 4-way, 16 GB virtual machines running SAP dialog instances.

Microsoft Clustering Services on vSphere 5

VMware has released an updated guide to deploying Microsoft Clustering Services on vSphere (link below). The guide provides deployment options and procedures for building MSCS Clusters on vSphere 5. Along with these instructions you will find a checklist to verify that your setup meets the requirements as well as best practices for using vSphere HA and DRS.

In addition to this comprehensive guide for most MSCS scenarios we've also published a KB article which sheds a bit more light onto disk configurations and the differences between "shared disk" and "non-shared disk" configurations and support.

Microsoft Exchange 2010 Performance on vSphere 5

The VMware performance team is constantly working to show how virtualizing tier 1 applications on vSphere can provide comparable performance to physical deployments. With the release of vSphere 5 we can now provide up to 32 vCPUs and 1TB of memory per VM! That kind of scale-up capability means there are very few (if any) workloads that we can't accommodate.

When dealing with Exchange 2010 designs there are recommended maximums that should be followed to achieve the best performance. Those recommendations are published by Microsoft on TechNet. For stand-alone mailbox servers the recommended maximum is 12 CPU cores, when working with six core CPUs. For multi-role servers the recommended maximum is 24 CPU cores, again when working with six core CPUs. For those customers that prefer to run very large instances (>8 vCPUs) of Exchange servers vSphere 5 now makes this possible.

In keeping with tradition the VMware performance team has published a whitepaper examining how Exchange 2010 performs on vSphere 5 in terms of scaling up (adding more vCPUs) and scaling out (adding more VMs). This paper shows that vSphere 5 can provide flexibility in deployment while maintaining a positive user experience.

For the full paper see Microsoft Exchange Server 2010 Performance on vSphere 5.
