Reading Time-approximately: 3 minutesA hybrid hard drive (HHD), sometimes known as a solid-state hybrid drive (SSHD), is a mass storage device that combines a conventional hard disk drive (HDD) and a NAND flash module. An HHD blends the capacity, cost and performance of physical disk storage with the accelerated performance of flash. By Garry Kranz Data that is frequently written to or retrieved from storage is served
Reading Time-approximately: 2 minutesIn computing, uptime is a measure of how long a computer or service is on and available. Downtime is the measure of how long it is not available. Services measure uptime as a percentage of total time. By Gavin Wright What is uptime? Uptime tells users how long a computer or service has been available. Historically, uptime was mainly a measure
Reading Time-approximately: 3 minutesFault-tolerant technology is a capability of a computer system, electronic system or network to deliver uninterrupted service, despite one or more of its components failing. Fault tolerance also resolves potential service interruptions related to software or logic errors. The purpose is to prevent catastrophic failure that could result from a single point of failure. By Garry Kranz VMware vSphere 6 Fault Tolerance is a branded, continuous data
Reading Time-approximately: 2 minutesSecond-level address translation (SLAT) is a hardware virtualization technology that reduces hypervisor overhead. Post courtesy of TechTarget SLAT addresses the inefficiencies associated with looking up virtualized memory addresses in software shadow volumes. The technology exists as a CPU feature: an added translation lookaside buffer (TLB) that contains a real-time updated cache of virtualized memory addresses and their corresponding physical addresses. Virtualization is a core technology for many data centers,
Reading Time-approximately: 8 minutesA data lake is a storage repository that holds a vast amount of raw data in its native format until it is needed for analytics applications By Craig Stedman and Ben Lutkevich While a traditional data warehouse stores data in hierarchical dimensions and tables, a data lake uses a flat architecture to store data, primarily in files or object storage. That gives users more
Reading Time-approximately: 2 minutesA converged network adapter (CNA) is a single network interface device that provides the functionality of both a Fibre Channel (FC) host bus adapter (HBA) and a TCP/IP Ethernet network interface card (NIC) By Robert Sheldon and Todd Erickson CNAs connect servers to FC-based storage area networks (SANs) and Ethernet-based local area networks (LANs). A CNA attaches to a server via a
Reading Time-approximately: 4 minutesBig Tech is a term that refers to the most dominant and largest technology companies in their respective sectors. By Linda Rosencrance Their products and services are used globally and have become heavily relied upon by businesses and individuals alike, bringing up privacy, safety and Antitrust concerns about their influence and operations and whether strict regulations should be considered. What companies
Reading Time-approximately: 5 minutesA carbon offset is a credit that a person or organization can buy to decrease its carbon footprint. When the number of carbon offset credits obtained is equal to an individual or organization’s carbon footprint, that person or organization is carbon-neutral. By Ben Lutkevich Revenue generated from the purchase of carbon offsets is often — but not always — invested in
Reading Time-approximately: 5 minutesThe metal-oxide semiconductor field-effect transistor (MOSFET, pronounced MAWS-feht) is the most common type of field-effect transistor (FET). By Gavin Wright They act as electrical switches and amplifiers controlling the amount of electricity that can flow between the source and drain terminals based on the voltage applied to the gate terminal. MOSFET is the underlying technology for most discrete transistors, digital logic, integrated circuits
Reading Time-approximately: 3 minutesIT asset disposition (ITAD) is an industry term and practice built around reusing, recycling, repurposing, repairing or disposing of unwanted IT equipment in a safe and environmentally responsible way. By Alexander S. Gillis An IT organization can practice IT asset disposition itself or have a specialized vendor handle it. Instead of ending up as electronic waste, or e-waste, in a landfill,
What is COVID-19?
On 31 December 2019, the World Health Organization (WHO) reported a cluster of pneumonia cases in Wuhan City, China. ‘Severe Acute Respiratory Syndrome Coronavirus 2’ (SARS-CoV-2) was confirmed as the causative agent of what we now know as ‘Coronavirus Disease 2019’ (COVID-19). Since then, the virus has spread to more than 100 countries, including South Africa.
