WikitipBeware of blades bearing high availability giftsIT organizations should be wary of promisinghigh availability web services built on blades or any other commodity hardware and software. Where they exist, IT should first qualify and make available external services built on high availability infrastructures that are protected from component failure. The challenge, as always, is recovery. Whereas commodity hardware can fail over instantly, recovery remains a complex and sometimes tedious and fragile task. |
Featured Case StudyVirtualization Energizes Cal State UniversityJohn Charles is the CIO of California State University, East Bay (CSUEB) and Rich Avila is Director, Server & Network Operations. In late 2007 they were both looking down the barrel of a gun. The total amount of power being used in the data center was 67KVA. The maximum power from the current plant was 75kVA. PG&E had informed them that no more power could be delivered. They would be out of power in less than six months. A new data center was planned, but would not be available for two years. |

Featured How-To Note |
Storage Virtualization Design and DeploymentA main impediment to storage virtualization is the lack of multiple storage vendor (heterogeneous) support within available virtualization technologies. This inhibits deployment across a data center. The only practical approach is either to implement a single vendor solution across the whole of the data center (practical only for small and some medium size data centers) or to implement virtualization in one or more of the largest storage pools within a data center. |
