Reading Time-approximately: 3 minutesCPUs have evolved to meet ever-increasing technology demands. We look at the way performance and power characteristics have shifted in recent years. By Brien Posey When purchasing server hardware, organizations have always had to decide on CPU type. In the early days, this decision might have been as simple as choosing between an Intel or AMD processor. There are now
Reading Time-approximately: 5 minutesSelecting the right CPU for virtual infrastructures depends on many factors, including feature sets and hardware specs. Proper configuration of processor resources is also crucial. By Ryann Burnett Choosing a CPU for virtualization and configuring it properly are just as important as choosing memory, storage and network resources. A processor that doesn’t make sense for the infrastructure or one that’s
Reading Time-approximately: 5 minutesIntel, AMD and Arm processors optimize virtualization in multiple ways. Read up on the features for Intel VT, AMD-V, Armv9, Intel APICv, and AMD AVIC tech, as well as how they support VMs. By Stephen J. Bigelow Chipmakers Intel, AMD and Arm Ltd. implement instruction set extensions that enable hardware support for virtualization, but it can be difficult to make
Reading Time-approximately: 3 minutesVirtual storage offerings are not one size fits all. Factors in virtualized storage software selection include storage type, current infrastructure and management tools. By Brien Posey Storage virtualization is one way admins can improve migration speed, host more than one array type and make costs more predictable. Yet, like any technology, IT managers must ensure whatever software tool they choose
Reading Time-approximately: 3 minutesScalable Processor Architecture (SPARC) is a 32- and 64-bit microprocessor architecture developed by Sun Microsystems in 1987. By Rahul Awati SPARC is based on reduced instruction set computing (RISC). SPARC has become a widely used architecture for hardware used with UNIX-based operating systems, including Sun’s own Solaris systems. Sun made SPARC an open architecture that is available for licensing to microprocessor manufacturers. Sun was acquired by Oracle Corporation in January
Reading Time-approximately: 4 minutesEdge virtualization is the practice of using software versions of physical computing resources at the edge of a network, closest to the devices that produce data. By Ben Lutkevich In virtualization, the entire software stack — including operating systems (OSes) and everything that runs on them — is separated from the underlying hardware. Instances can then be copied and distributed to
Reading Time-approximately: 3 minutesChoosing the right CPU for virtual infrastructures depends on several factors, including feature sets and hardware specs. Proper configuration of processor resources is also crucial. By Ryann Burnett Choosing a CPU for virtualization and properly configuring it are just as important as choosing memory, storage and network resources; a processor that doesn’t make sense for the infrastructure or one that’s
Reading Time-approximately: 5 minutesVirtualization sprawl is a phenomenon that occurs when the number of virtual machines (VMs) on a network reaches a point where administrators can no longer manage them effectively. By Robert Sheldon Virtualization sprawl is also referred to as virtual machine sprawl, VM sprawl or virtual server sprawl. VM sprawl has become a common challenge for many organizations, and the more they rely on virtualization,
Reading Time-approximately: 3 minutesHardware-assisted virtualization is the use of a computer’s physical components to support the software that creates and manages virtual machines (VMs). Virtualization is an idea that traces its roots back to legacy mainframe system designs of the 1960s. By Stephen J. Bigelow Early mainframes used the Control Program/Conversational Monitor System operating system and were adept at provisioning the mainframe’s available computing resources into isolated environments
Reading Time-approximately: 3 minutesVMware moved its per-CPU licensing plan closer to competitors’ per-core licensing plans by requiring one license for CPUs with 32 cores. By Ed Scannell VMware has changed its licensing model to limit the number of cores per CPU in a move that aligns with the per-core pricing model used by many major software companies, but is expected to increase costs for customers
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.
