Understanding storage technologies
Can you imagine an application server without RAM or a file server without an HDD? These questions may sound odd because RAM and HDD are inseparable from today’s computer systems. This section aims to show you how vital storage technologies are to computers and that they come in various types, shapes, and sizes for different purposes. Besides the fact that storage technologies are an objective of the certification exams, their importance is absolute in information and communications technology (ICT). Therefore, this chapter is dedicated to storage technologies.
In most cases, the server will likely require ample storage space besides high processing power, sufficient RAM, and several network connections. Whether it’s a single server or a cluster of servers, IDE, SAS, SCSI, DAS, NAS, SAN, and RAID represent various storage technology options.
Let’s begin by understanding what the different storage types are.
