See how cable management software helps organizations visualize network connectivity. By David Jacobs As a network manager, perhaps you document the connections between ports. But do your records include all the information you need to maintain the network efficiently? While a spreadsheet that lists port-to-port connections may seem sufficient,
Reading Time-approximately: 7 minutesThis guide to network management explains the challenges of enterprise network monitoring and maintenance, best practices and next-generation automation using AI and ML. By Chuck Moozakis and Sandra Gittlen Network management is a cornerstone of IT that helps ensure enterprises run efficiently and effectively end to end. Technologies such as AI and machine learning are beginning to automate many of the functions of network administration and
Reading Time-approximately: 4 minutesA computer network is a system of computers and computing devices that are connected via communication links. By Ben Lutkevich and Kate Gerwig These links allow the computers and other devices to send information over the network. Network protocols define how information is sent and received. Networks can be defined by their geographic location, the protocols they use, the physical arrangement
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,
Reading Time-approximately: 4 minutesNVMe 2.0 added several features for storage administrators to consider, including domain support. The specification also made enhancements, such as to Endurance Group Management. By Jim Handy The NVMe 2.0 specification, published in June 2021, introduced changes to improve performance and to support new uses of NVMe. While NVMe originally supported only block storage, which was the way that storage
Reading Time-approximately: 3 minutesRoute summarization — also known as route aggregation — is a method to minimize the number of routing tables in an IP network. By Rahul Awati It consolidates selected multiple routes into a single route advertisement. This differentiates it from flat routing, in which every routing table carries a unique entry for each route. In basic terms, a route advertisement contains information that devices can use
Reading Time-approximately: 2 minutesA motherboard tattoo is a colloquial term once used to denote an ID code that is written in the basic input/output system (BIOS) of a computer to uniquely identify the computer. 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
