Optimizing and Protecting Hard Drives ‐ Chapter # 9
Optimizing and Protecting Hard Drives ‐ Chapter # 9 Amy Hissom Key Terms antivirus (AV) software — Utility programs that prevent infection or scan a system to detect and remove viruses. McAfee Associates’ VirusScan and Norton AntiVirus are two popular AV packages. backup — An extra copy of a file, used in the event that the original becomes damaged or destroyed. boot sector virus — An infectious program that can replace the boot program with a modified, infected version of the boot command utilities, often causing boot and data retrieval problems. buffer — A temporary memory area where data is kept before being written to a hard drive or sent to a printer, thus reducing the number of writes to the devices. chain — A group of clusters used to hold a single file. child, parent, grandparent backup method — A plan for backing up and reusing tapes or removable disks by rotating them each day (child), week (parent), and month (grandparent). cross-linked clusters — Errors caused when more than one file points to a cluster, and the files appear to share the same disk space, according to the file allocation table. defragment — To “optimize” or rewrite a file to a disk in one contiguous chain of clusters, thus speeding up data retrieval. differential backup — Backup method that backs up only files that have changed or have been created since the last full backup. When recovering data, only two backups are needed: the full backup and the last differential backup. disk cache — A method whereby recently retrieved data and adjacent data are read into memory in advance, anticipating the next CPU request. -

The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the information. 8 Forensics - Definitions • Network Forensics [3]: – Network forensics is a sub-branch of digital forensics relating to the monitoring and analysis of computer network traffic for the purposes of information gathering, legal evidence, or intrusion detection.[1] Unlike other areas of digital forensics, network investigations deal with volatile and dynamic information. -
CD-ROM, CD-R, CD-RW, and DVD-ROM Drives) Are the Hardware Devices That Read Computer Data from Disks
A Brief History of CD/DVD The first disc that could be written and read by optical means (using light as a medium) was developed by James T. Russell. In the late 1960s, Russell created a system that recorded, stored, and played audio/video data using light rather than the traditional contact methods, which could easily damage the disks during playback. Russell developed a photosensitive disc that stored data as 1 micron-wide dots of light and dark. The dots were read by a laser, converted to an electrical signal, and then to audio or visual display for playback. Russell's own company manufactured the first disc player in 1980, although the technology never reached the marketplace until Philips and Sony developed the technology. In late 1982, Philips and Sony released the first of the compact disc (CD) formats, which they then called CD-DA (digital audio). In the years since, format has followed format as the original companies and other industry members developed more adaptations of the original specifications. Digital Versatile disc (DVD) had its beginning in 1994, when two formats, Super disc (SD) and Multimedia CD (MMCD) were introduced. Promoters of the competing technologies failed to reach an agreement on a single standard until 1996, when DVD was selected as a convergence format. DVD has, in the few years since, grown to include variations that do anything that CD does, and more efficiently. Standardization and compatibility issues aside, DVD is well-placed to supplant CD. Magnetic vs Optical Media Optical media are storage media that hold information in digital form and that are written and read by a laser; these media include all the various CD and DVD variations, as well as optical jukeboxes and autochangers. -
Softnas Deployment Guide for High- Performance SQL Storage
SoftNAS Deployment Guide for High- Performance SQL Storage Introduction SoftNAS cloud NAS systems are based on an innovative, memory-centric storage architecture that delivers unparalleled NAS performance, efficiency, and value. They incorporate a hybrid disk storage technology that tailors the usage of data disks, log solid- state cache drives (SSDs), and read cache SSDs to the data share's specific needs. Additional features include variable storage record size, data compression, and multiple connectivity options. As a Cloud NAS solution, SoftNAS cloud NAS systems provide an excellent base for Microsoft Windows Server deployments by providing iSCSI or Fibre Channel block storage for Microsoft SQL Server, and network file system (NFS) or server message block (SMB) file storage for Microsoft Windows client access. This document covers the best practices to follow when deploying Microsoft SQL Server on a SoftNAS cloud NAS system. The intended audience is storage administrators and Microsoft SQL Server database administrators. Maintaining High Availability As with any business-critical application, high availability is a crucial design criterion to be considered when deploying a Microsoft SQL Server installation. Microsoft SQL Server 2016 can be installed on local and/or shared file systems, and SoftNAS cloud NAS systems can satisfy both of these options. Local file systems (from the Microsoft Windows Server perspective) are hosted as block volumes—iSCSI and/or Fibre-Channel-connected LUNs and file systems as SMB and/or NFS volumes. High availability starts with the network connectivity supporting the storage and server interconnectivity. Any design for the storage infrastructure should avoid single points of failure. Because many white papers and publications cover storage-area networking and network-attached storage resilience, those topics are not covered in detail in this paper. -
