Be sure to conduct visual, thermal and load tests to verify UPS health. By Brien Posey Data center power infrastructure maintenance is essential for operational continuity. In addition to regular battery health evaluation, you should also develop a maintenance plan for backup power options such as

By Robin Roy N+1 redundancy (or parallel redundancy) is a safeguard to ensure a UPS system’s availability in the event of component failure — especially in a tier 2 or a tier 3 datacenter. When considering an
Reading Time-approximately: < 1 minuteN+1, also called parallel redundancy, is a safeguard to ensure that an uninterruptible power supply (UPS) system is always available. N+1 stands for the number of UPS modules that are required to handle an adequate supply of power for essential connected systems, plus one more. Courtesy Post for Tekmart Enterprise Support If an enterprise data center uses a single large UPS, and that module fails,

By Robert McFarlane Organizations traditionally deployed large, centralized power systems to provide battery backup to their infrastructure, but this approach was often inefficient if admins sized the backups to support future capacity. The emergence of modular uninterruptible power

Tekmart Africa Enterprise Sales Team Secondary-market resellers are perhaps best known for providing used, refurbished tech equipment at a fraction of retail cost. Like traditional vendors, secondary-market resellers also deal

It uses the iSCSI components while taking the advantage of the RDMA protocol suite. By Tekmart Enterprise Support ISER is an RDMA transport for iSCSI, the link protocol could be either Ethernet or InfiniBand at any

By Robert Sheldon SAN switches make it possible to build vast high-speed storage networks that interconnect thousands of servers accessing petabyte-scale data. At its most basic, a SAN switch manages traffic flow between the servers and storage devices, examining

By David Jacobs At the onset of the COVID-19 pandemic, the stay-at-home orders came quickly and with minimal warning. Chances are you turned off the office lights, locked the door and headed home. Maybe you

By Tekmart Enterprise Support As a result, the available memory for that application or that part of the operating system becomes exhausted and the program can no longer function. For a

By Tekmart Africa Enterprise Support In addition, NIC partitioning allows administrators to dedicate bandwidth for VMs and associated applications and to apply QoS to the virtual ports, helping improve I/O
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.
