While you need sufficient processing power and a sufficient amount of RAM, you will also most likely need a large amount of storage. Although simple servers usually require that you install Windows Server on a local IDE (parallel and serial) or SCSI hard drive, more complex systems may use a form of RAID or attached remote computer storage devices such as a storage area network (SAN) or network attached storage (NAS). Discuss these advanced storage options and provide examples of real-life scenarios where options such as SAN or NAS should be implemented.
