Reading Time-approximately: 6 minutesExplore the best, most optimal architectures for intelligent storage and how these systems improve storage performance/utilization to help get more bang out of your data set buck. By Dan Sullivan Brute force has been the critical lever to achieving advances in storage technology for much of its history. Making storage devices bigger, faster and denser has worked well and will
Reading Time-approximately: 4 minutesA MAC address and an IP address each identify network devices, but they do the job at different levels. Explore the differences between the two and learn why both are necessary. By John Burke and Chris Partsenidis Every computer or device on the internet has two types of addresses: its physical address and its internet address. The physical address —
Reading Time-approximately: 4 minutesWireless LAN integration means upgrading wired networks with new equipment and traffic prioritization to avoid bottlenecks between the networks and provide QoS for wireless multimedia applications, including WLAN voice and video. By Lisa Phifer In the first part of this series, we discussed how to make the business case for integrated wired and wireless LANs. In this tip, learn how to
Reading Time-approximately: 4 minutesMany installers make the mistake of treating 802.11 WLANs just like Ethernet, placing access points (APs) in locations that facilitate outsider access to corporate networks. By Tekmart Enterprise Hardware Support But, from a security perspective, WLANs should be treated like the Internet — a network composed of trusted and untrusted users. This tip offers network topology and physical positioning recommendations
Reading Time-approximately: 3 minutesAlthough a router, switch and hub all help direct network traffic, the devices transmit packets in different ways. Discover the differences among these network devices. By Andrew Froehlich While routers, switches and hubs are all network devices, they all serve different purposes. A network hub is a node that broadcasts data to every computer or Ethernet-based device connected to it. A switch
Reading Time-approximately: 3 minutesEven though they have common traits, there is a difference between a Layer 3 switch and a router. Each plays a key role in making sure packets get sent to their proper destination. By Andrew Froehlich To determine the difference between a Layer 3 switch and a router, it’s helpful to understand how routing works in an enterprise network. Routing
Reading Time-approximately: 2 minutesWhile VLANs are a type of subnet, they have their own unique capabilities and characteristics that differentiate them from subnets. However, the OSI model plays a major role in both. By Andrew Froehlich A prevailing question that many new network administrators ask is the difference between virtual LANs — or VLANs — and IP subnetworks, or subnets. While instances occur
Reading Time-approximately: 8 minutesNVMe (non-volatile memory express) is a host controller interface and storage protocol created to accelerate the transfer speed of data between enterprise and client systems and solid-state drives (SSDs) over a computer’s high-speed Peripheral Component Interconnect Express (PCIe) bus. Posted by: Margaret Rouse WhatIs.com Contributor(s): Rich Castagna; Carol Sliwa As solid-state technology became the preferred medium in the storage market, it quickly became clear that existing interfaces
Reading Time-approximately: 6 minutesSAS and NVMe both play significant roles in enterprise storage. See how the two interfaces stack up in terms of performance, scalability, flexibility, manageability and the future. By Stacey Peterson As NVMe SSDs make inroads into the enterprise market, the question remains: What’s in store for SAS drives? While they don’t provide the performance enhancements and latency reduction of NVMe SSDs, they
Reading Time-approximately: 5 minutesCloud infrastructure refers to the hardware and software components — such as servers, storage, a network, virtualization software, services and management tools — that support the computing requirements of a cloud computing model. Posted by: Margaret Rouse WhatIs.com Contributor(s): James Montgomery; Kurt Marko; Nicholas Rando; Beth Pariseau; Alex Barrett Cloud infrastructure also includes an abstraction layer that virtualizes and logically presents resources and services to
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.
