In this chapter, we will review the technology decisions to be made in terms of the hardware required for a RAC cluster. The question of hardware is often neglected by DBAs; however, for a well-tuned application, the potential performance improvements offered by the latest server, interconnect, and storage architectures running the current versions of Linux is greater than those achievable by upgrades or software tuning on previous generations of technology. For this reason, hardware is a crucial topic of consideration for designing the best RAC configurations; this is particularly true for understanding how all of the components operate in conjunction for optimal cluster performance.
