Once you decide to take on a server consolidation project using virtualization, you face a host of data center virtualization infrastructure challenges, including server hardware choices, network optimization, the right processors and memory capacity. You should consider which server would be the best virtualization platform for your environment -- blade servers, rackmount servers, legacy mainframe system or cloud computing platforms -- in terms of the virtualized workloads you will deploy, your data center footprint, and data center power and cooling requirements. You also want an adequate number of networking interface card (NIC) slots and host bus adapters (HBAs) and you need to choose the best networking options for virtual machine traffic, including PCI express, InfiniBand, Ethernet, of Fibre Channel. Choosing the right CPUs and server memory capacity for virtualization is also necessary. This section on server hardware choices for data center virtualization helps you weigh server hardware options and features in terms of cost, performance, reliability, support, interoperability and other factors to optimize server performance and server efficiency. You will learn which server hardware products and features are best suited for production environments, test and development, disaster recovery, high performance computing, and cloud computing, and how to optimize memory, CPU, networking, server configuration and management and virtualization hardware support.
