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: 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: 2 minutesBy Tekmart Africa Enterprise Support Hard drives that come with the Serial Attached SCSI (SAS) interface are designed to handle high-performance enterprise requirements. These drives offer the benefits of backward compatibility with SCSI interfaces. They also offer interoperability with SATA drives. This allows them to bring a perfect mix of flexibility and cost-effectiveness to enterprises. SAS 6Gbps hard drives are suitable
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

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.
