With advances in virtualization technology, both at the hardware and software layer, more and more virtual machines and hence applications are being run on a single server. While this improves consolidation ratios, it also presents new challenges, especially the risk of losing multiple critical applications in case of a fault at any layer of the infrastructure. This white paper presents a sample Dell solution -- using the Dell R610 and R710 PowerEdge Servers (powered by Intel® Xeon® processor 5500 Series) -- designed to tolerate faults at multiple infrastructure layers to provide maximum level of availability for the virtual infrastructure.
