Hard Partitioning with Oracle Linux KVM

October 11, 2019

On an x86-based system, a CPU core (no hyperthreading enabled) or a CPU thread (hyperthreading enabled) within a core is presented as a physical CPU by the hypervisor or the bare metal operating system. vCPUs (virtual CPUs) are exposed to the guest virtual machine as CPUs: the guest schedules applications on these vCPUs, and the hypervisor schedules these vCPUs over the physical CPU cores or threads. All vCPUs from a guest are symmetrical. Oracle Linux KVM treats these equally, as long as scheduling parameters such as using CPU pinning have not changed.

Why VDI makes sense forhard-core UNIX® and Linux® engineering applications

whitePaper | December 6, 2022

By now, everyone has heard the terms desktop virtualization and VDI It seems like we’ve been pounded with marketing propaganda about these technologies from companies like VMware, Citrix® and Microsoft® since 2006. But if desktop virtualization is so good, why are most of the world’s desktops still “old-style” physical desktops and laptops?

The Total Economic Impact of Data Virtualization Using the Denodo Platform

whitePaper | September 8, 2022

Data virtualization helps organizations access data across disparate sources and deliver a unified view of the data faster, cheaper, and using fewer resources than traditional data integration approaches. In this TEI, data virtualization delivered 83% reduction in time-torevenue and 65% decrease in delivery times over extract, transform, and load (ETL) processes.

Virtual software platform for the car

whitePaper | October 4, 2022

Virtualization technology is gaining acceptance in the automotive industry. It makes the development process of software systems more efficient, reduces development and BOM costs, and shortens time-to-market. Especially in the cockpit, manufacturers and their direct suppliers have now been using hypervisor-based systems for several years. This first step towards a new conception of solutions is now experiencing another paradigm shift: the use of open standards. It further enhances the advantages of virtualization. The fully virtualized guest operating systems can be flexibly deployed and reused across all hardware. Only then can the full potential of virtualization technology be fully exploited

Virtualized RAN Challenges Debunked

whitePaper | January 17, 2020

Mobile network operators (MNOs) are now considering ways to take advantage of the benefits that Virtualized RAN (vRAN) can deliver. vRAN gives MNOs greater network availability and better deployment flexibility using pooled, centralized resources that are operating on standardized commercially available hardware. The virtualized functions that provide the network’s baseband processing in vRANs also lower CAPEX and OPEX by reducing cell site real-estate space and the power needs of the equipment that no longer resides on-site.

Networking for the unforeseeable future

whitePaper | June 29, 2022

When it was introduced, MPLS was an ideal option for organizations that ran multiple business-critical applications at multiple locations. Operated and managed by a single carrier, MPLS converges voice and data traffic over connections that are isolated from the public Internet, while offering rudimentary control over applications.
