Windows Server makes it easy to configure both failover and load balancing. By Damon Garn The role of the Dynamic Host Configuration Protocol, or DHCP, server is a simple yet critical one. DHCP provides the IP address configuration to workstations, laptops, phones and tablets connected
Reading Time-approximately: 2 minutesLoad sharing and load balancing are two techniques that work to distribute traffic across a network. However, their methods of balancing differ significantly. Here’s how. By Andrew Froehlich Load sharing and load balancing both achieve the same goal of meeting application and service delivery requirements based on traffic load. When comparing how to achieve this goal from a technical perspective,

By Gavin Wright This ID code is used to ensure that system restore, or diagnostic CDs will only work with the computer they come with. It is set by
Reading Time-approximately: 4 minutesA host bus adapter (HBA) is a circuit board or integrated circuit adapter that connects a host system, such as a server, to a storage or network device. By Robert Sheldon and Carol Sliwa An HBA also provides input/output (I/O) processing to reduce the load on the host’s microprocessor when storing and retrieving data, helping to improve the host’s overall performance. An HBA and its associated disk subsystems are sometimes

By StorageReview Enterprise Lab Crucial just released the new 4TB capacity of the long-standing MX500 SATA SSD, which may just be a perfect price and performance mix for a low-cost all-flash storage setup. We installed eight of these SSDs
Reading Time-approximately: 5 minutesMRAM (magnetoresistive random access memory) is a method of storing data bits using magnetic states instead of the electrical charges used by devices such as dynamic random access memory (DRAM). By Robert Sheldon and Rodney Brown By combining the high speed of static random access memory (SRAM) and the high density of DRAM, MRAM promises to significantly improve electronic products
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.
