This book which is available for pre-order now, covers solving vSphere performance problems. VMware vSphere is the industry's most widely deployed virtualization solution. However, due to poor or improper deployment of vSphere, performance problems occur. Aimed at VMware administrators and engineers and written by a team of VMware experts, this resource provides guidance on common CPU, memory, storage, and network-related problems. Plus, step by-step instructions walk you through techniques for solving problems and shed light on possible causes behind the problems.

Divulges troubleshooting methodologies, performance monitoring tools, and techniques and tools for isolating performance problems Details the necessary steps for handling CPU, memory, storage, and network-related problems Offers understanding on the interactions between VMware vSphere and CPU, memory, storage, and network VMware vSphere 5 Performance is the resource you need to diagnose and handle VMware vSphere performance problems.

The folks at Xsigo have done some performance benchmarking  -- on their own server fabric but still, in this emerging space, numbers are still hard to come by and these illustrate some of what’s possible as the industry moves in this direction.  

This is a really short write-up they did with info on the test bed, the tests performed and some graphs and screenshots, but the summary results show that compared to 1G and 10G Ethernet, the Xsigo ServerFabric delivered: 

• 2.4X the Ethernet traffic of a 10G Ethernet connection (throughput to a single virtual machine)
• 20Gbps throughput measured to a single NIC on a single virtual machine
• 15X faster vMotion than1G Ethernet 
• 67% faster vMotion than 10G Ethernet

In performance benchmark testing, the Xsigo Server Fabric demonstrated significantly higher network device throughput as compared to 1G Ethernet and 10G Ethernet server connections.

This paper is intended to clarify concepts involved with choosing solutions for vSphere site availability, and to help understand the use cases for availability solutions for the virtualized infrastructure. Specific guidance is given around the intended use of DR solutions like VMware vCenter Site Recovery Manager and contrasted with the intended use of geographically stretched clusters spanning multiple datacenters. While both solutions excel at their primary use case, their strengths lie in different areas which are explored within.

Microsoft SQL Server 2012 is Microsoft’s first cloud-ready information platform. It gives organizations effective tools to protect, unlock, and scale the power of their data, and it works across a variety of devices and data sources, from desktops, phones, and tablets, to datacenters and both private and public clouds. Our (Ross Mistry and Stacia Misner) purpose in Introducing Microsoft SQL Server 2012 is to point out both the new and the improved capabilities as they apply to achieving mission-critical confdence, breakthrough insight, and using a cloud on your terms.

As you read this book, we (Ross Mistry and Stacia Misner) think you will fnd that there are a lot of exciting enhancements and new capabilities engineered into SQL Server 2012 that allow you to greatly enhance performance and availability at a low total cost of ownership, unlock new insights with pervasive data discovery across the organization and create business solutions fast—on your terms.
