Reading Time-approximately: 6 minutesIncreasing reliance on cloud storage is changing the way storage area networks are managed and the challenges that SAN admins face in responding to business requirements. By Stephen Engelhardt Data has grown at an unprecedented pace for years, and storage management has had to change to keep up. Industry observers have repeatedly predicted that storage area networks would become obsolete.
Reading Time-approximately: 4 minutesA storage area network (SAN) switch is a device that connects servers and shared pools of storage devices and is dedicated to moving storage traffic. 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
Reading Time-approximately: 2 minutesA virtual storage area network (VSAN) is a logical partition in a physical storage area network (SAN). VSANs enable traffic to be isolated within specific portions of a storage area network, so if a problem occurs in one logical partition, it can be handled with a minimum of disruption to the rest of the network. By John Edwards The use of multiple,
Reading Time-approximately: 3 minutesDemilitarized zone, network access control and VPN termination points are some of the on-premises components that need to be addressed in a remote work infrastructure. 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
Reading Time-approximately: 3 minutesEven though vendors refer to flash memory and conventional RAM — the main memory of your PC or server — as solid-state memory, these two memory types are significantly different. By Erin Sullivan and Rodney Brown When discussing flash memory vs. RAM, you might be inclined to lump them together based on their similarities. While both technologies are made up of solid-state
Reading Time-approximately: < 1 minuteA memory leak is the gradual loss of available computer memory when a program (an application or part of the operating system) repeatedly fails to return memory that it has obtained for temporary use. 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
Reading Time-approximately: 3 minutesNIC partitioning is a method of dividing a single physical Ethernet port into four partitions, or virtual ports, which enables administrators to conserve PCI Express (PCIe) slots in the physical host server. 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
Reading Time-approximately: 3 minutesAs more employees work remotely and VPN use rises, VPN concentrators have become trendy. But what does a VPN concentrator do exactly, and how do you deploy one? By Terry Slattery Virtual private networks are encrypted tunnels that protect network communications from unauthorized access when the communications must cross untrusted networks, like the internet. VPN concentrators are one component that
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 —
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.
