Overview of this book

CompTIA Server+ Certification is one of the top 5 IT certifications that is vendor neutral.System administrators opt for CompTIA server+ Certification to gain advanced knowledge of concepts including troubleshooting and networking. This book will initially start with the configuration of a basic network server and the configuration for each of its myriad roles. The next set of chapters will provide an overview of the responsibilities and tasks performed by a system administrator to manage and maintain a network server. Moving ahead, you will learn the basic security technologies, methods, and procedures that can be applied to a server and its network. Next, you will cover the troubleshooting procedures and methods in general, and specifically for hardware, software, networks, storage devices, and security applications. Toward the end of this book, we will cover a number of troubleshooting and security mitigation concepts for running admin servers with ease.

Hard disk interfaces

Although it may be inside the system case, an HDD is a peripheral device to the motherboard and CPU. An HDD and a computer communicate, that is, pass data to each other, through a drive interface. A drive interface is the bus structure that the device driver, the hard disk device, RAM, and controllers use to pass data requests and the data requested.

HDD interfaces are either word-serial or bit-serial. Word-oriented interfaces transfer data in 8-bit, 16-bit, or 32-bit words using parallel bit signaling. Examples of word-oriented interfaces are the Small Computer Serial Interface (SCSI) and the Parallel Advanced Technology Attachment (PATA). Bit-oriented interfaces interconnect through a host bus adapter (HBA). Examples of bit-oriented interfaces are fibre channel (FC), serial ATA (SATA), and serial attached SCSI (SAS).
