Reading Time-approximately: 3 minutesLarge VMware hosts can be advantageous, but VM density can have unforeseen consequences during a system failure. Evaluate VM functionality to ensure you’re ready for a disaster. By Brian Kirsch Large VMware hosts can seem attractive, but the resultant VM density can reduce your ability to quickly recover from failure. It’s tempting to examine VMware hosts from a hardware perspective
Reading Time-approximately: 5 minutesAre NAS storage devices a fit for a virtual server environment? We list factors in choosing these devices, and explain their impact on your storage systems. By Eric Siebert What you will learn: We’ll help you determine whether or not network-attached storage (NAS) devices are right for your virtualized server environment. In most cases, NAS performance won’t equal that of a
Reading Time-approximately: 4 minutesTake a deep dive into seven reasons, including performance issues and scalability demands, an SMB would want to ditch NAS in favor of entry-level SAN. By Robert Sheldon Storage area networks were once limited to large organizations with the resources to deploy and maintain these complex systems. Prices have decreased, however, and SANs have become a viable option for small
Reading Time-approximately: 6 minutesDatacenter SSDs are not just higher performance and more expensive versions of desktop-grade devices. They have unique features that are critical for storage systems. Guest Post There are a number of companies who use consumer-grade SSDs for powering their business. Usually, the story goes along the lines of “consumer SSDs are just as good as Datacenter SSDs, and they are
Reading Time-approximately: 3 minutesSSDs have taken the consumer market by storm, but data centers should treat them carefully Adrien Viaud Changing consumption habits and cloud applications are having a strong impact on the demand for data centers, and impacting data center configurations as well. On top of that, storage hardware is evolving, with new technology such as U.2, NVMe and PCIe bringing lower

By Peter Loshin Threat actors targeting large organizations — even ones with effective cybersecurity defenses — will go to any length to get in. Even when the targeted organization does a good
Reading Time-approximately: 7 minutesA blade server, sometimes referred to as a high-density server, is a compact device containing a computer used to manage and distribute data in a collection of computers and systems, called a network. Its role is to act as a conduit between computers, programs, applications and systems. By Laura Fitzgibbons In general, a blade server consists of a chassis, or box-like
Reading Time-approximately: 4 minutesWhite box switches separate two long-intertwined data center components: Networking hardware and the network operating system that runs on it. With such a marked change, it’s no wonder open networking isn’t for everyone. By Ethan Banks The jury’s still out on software-defined networking, but white box switching just might stand the test of time. Disruption is a technology buzzword applied to any
Reading Time-approximately: 2 minutesWhite box switches and hyper-convergence are two upgrades that can breathe new life into your data center network. Learn what they are and how to make them work for you. By David Jacobs Two recent developments promise to alter the ways that compute environments are built and managed. The first, white box switches, lowers network component costs while increasing the
Reading Time-approximately: 6 minutesStorage virtualization is the pooling of physical storage from multiple storage devices into what appears to be a single storage device — or pool of available storage capacity — that is managed from a central console. The technology relies on software to identify available storage capacity from physical devices and to then aggregate that capacity as a pool of storage
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.
