Reading Time-approximately: 12 minutesFlash memory, a staple of consumer electronics, is playing a wider role in enterprise storage. This guide offers an overview of flash, from current use cases to future directions. By John Moore Flash memory, also known as flash storage, demands a closer look. The technology permeates a multitude of consumer products, from mobile phones to ubiquitous USB memory cards. Enterprise
Reading Time-approximately: 3 minutesHot plugging is the addition of a component to a running computer system without significant interruption to the operation of the system. By Ben Lutkevich Hot plugging a device does not require a restart of the system. This is especially useful for systems that must always stay running, such as a server. Common examples of hot-pluggable devices include hard disk drives (HDDs)
Reading Time-approximately: 6 minutesChoosing between the two hypervisor types largely depends on whether IT administrators oversee an enterprise data center or client-facing, end-user systems. ByStephen J. Bigelow and Brian Kirsch The main difference between Type 1 vs. Type 2 hypervisors is that Type 1 runs on bare metal and Type 2 runs on top of an operating system. Each hypervisor type also has
Reading Time-approximately: 3 minutesA Type 2 hypervisor, also called a hosted hypervisor, is a virtual machine (VM) manager that is installed as a software application on an existing operating system (OS). ByBrien Posey, Anil Desai and Colin Steele There are two types of hypervisors: Type 1 and Type 2. Type 2 hypervisors support guest virtual machines by coordinating calls for central processing unit (CPU), memory,
Reading Time-approximately: 3 minutesHyper-V and KVM are common hypervisor options. Before you commit to one, evaluate which OS type, available features and memory requirements work for your infrastructure. By Brien Posey Microsoft’s Hyper-V and Linux’s KVM are capable, enterprise-class hypervisors that can host VMs and scale to the largest of workloads. These options are both type 1 hypervisors, but there are some significant

Server virtualization also masks server resources, including the number and identity of individual physical servers, processors and operating systems. By Stephen J. Bigelow and Alexander S. Gillis Server virtualization is a process that creates and abstracts multiple virtual instances on a single server. Server
Reading Time-approximately: < 1 minuteSDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. By TechTarget Contributor This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM is rated in MHz rather than in nanoseconds (ns). This makes
Reading Time-approximately: 3 minutesMany organizations use legacy VPNs to secure their networks, especially in the work-from-home era. Expert Pranav Kumar explains why zero-trust models are a safer option. By Pranav Kumar Companies have been using VPNs for over two decades. The tool allows employees, contractors and other parties to access an organization’s internal data, assets and applications. Unfortunately, VPNs are ill equipped to
Reading Time-approximately: 4 minutesA disaster recovery plan may seem like an unnecessary expense to some businesses, but a lack of preparation will cost you. By Stuart Burns Some organizations question how much to invest in a disaster recovery plan. They’re reluctant to allocate significant budget and staff to systems they’ll need in the face of a disaster that may, or may not, occur.
Reading Time-approximately: 5 minutesExplore the various ways NVMe technology vendors are preparing the way for organizations to transition to storage class memory in their computing environments. By Marc Staimer NVMe has taken hold in the enterprise, driven by high-performance-demanding applications, such as AI, machine learning and analytics, and their need for high-speed, low-latency access to storage media. Now, storage class memory is making inroads,
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.
