Reading Time-approximately: 3 minutesThe principle of least privilege (POLP) is a concept in computer security that limits users’ access rights to only what are strictly required to do their jobs. Users are granted permission to read, write or execute only the files or resources necessary to do their jobs. This principle is also known as the access control principle or the principle of minimal privilege. By

Finding the right approach requires carefully assessing available technology, where you keep your data and costs. By John Edwards As more organizations contemplate transitioning to an energy-efficient data center, green data storage is gaining attention. With several storage technology choices available, the main challenge green storage adopters face is finding and following their best approach
Reading Time-approximately: 4 minutesYour data center UPS sizing needs are dependent on a variety of factors. Develop configurations and determine the estimated UPS capacity that will meet your current and future needs. By Robert McFarlane So you need an uninterruptible power supply unit, but you’re having trouble sizing it. How do you figure it out? Some uninterruptible power supply (UPS) systems are rated in kilowatts
Reading Time-approximately: < 1 minuteMTBF (mean time between failures) is a measure of how reliable a hardware product or component is. Courtesy Post: By TechTarget Contributor For most components, the measure is typically in thousands or even tens of thousands of hours between failures. For example, a hard disk drive may have a mean time between failures of 300,000 hours. A desired MTBF can
Reading Time-approximately: 7 minutesHigh availability (HA) is the ability of a system to operate continuously without failing for a designated period of time. HA works to ensure a system meets an agreed-upon operational performance level. In information technology (IT), a widely held but difficult-to-achieve standard of availability is known as five-nines availability, which means the system or product is available 99.999% of the time.

Reading Time-approximately: 3 minutesSANs consolidate resources and provide a high-speed network for storage traffic, but that doesn’t mean you’re off the hook when it comes to performance management. By Brien Posey Storage area networks can deliver the performance required by even the most demanding enterprise workloads. Even so, there are several SAN management best practices that must be followed to achieve the optimal

Minimize costs and outages with service contracts and emulation options. By Brien Posey All data center admins face legacy hardware maintenance. In a perfect world, data centers would be equipped solely with the most up-to-date generation of hardware. However, budgetary and operational requirements mean most infrastructure
Reading Time-approximately: 4 minutesAn uninterruptible power supply (UPS) is a device that allows a computer to keep running for at least a short time when the primary power source is lost. UPS devices also provide protection from power surges. By Robert McFarlane A UPS contains a battery that “kicks in” when the device senses a loss of power from the primary source. If an end
Reading Time-approximately: 4 minutesServer hardware degradation is the gradual breakdown of the physical parts of a server. By Brien Posey and Christine Cignoli There are several general areas where server degradation problems occur, including power, temperature, management and memory. The electric components inside servers age over time, and heat sinks and fans get clogged with dust, reducing the server’s efficiency and performance. Server life-cycle
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.
