New Book - VMware vSphere 5 Performance: Solving CPU, Memory, Storage, and Networking Issues

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.

Xsigo Server Fabric Performance Test Results

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.

Technical Paper - Stretched Clusters and VMware vCenter Site Recovery Manager

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.

The purpose of this paper is to clarify some of the concepts involved with vSphere site availability, and to help understand the use cases for these availability solutions in the vSphere landscape. The intent is to provide guidance not in terms of purchasing decisions or products, but in terms of what various technologies intend to do and how to best achieve availability goals for your environment.

When designing for availability, in many instances the solution architect will have to choose between these technologies. Stretched clusters are incompatible with Site Recovery Manager and therefore, the architect is faced with a decision whether to choose active non-disruptive site balancing with unmanaged crash recovery via a stretched cluster or choose a robust disaster recovery solution that will restart failed services in a controlled and known fashion but is predicated on service outage.
