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.

vSAN 2-Node Cluster on VxRail Planning Guide

whitePaper | January 15, 2020

VMware vSAN 2-node cluster is a configuration that is implemented in environments where a minimal configuration is a key requirement. VxRail v4.7.100 was the first release to support the vSAN 2-node cluster with direct-connect configuration. Starting with VxRail v4.7.410, vSAN 2-node cluster with switch configuration is also supported.

The definitive guide to secure remote access

whitePaper | December 22, 2021

Enterprises are migrating their private applications to public clouds, and users are consuming more applications, connecting to them from everywhere and from any device. This has created a proliferation of perimeters around users, devices, and applications. Although many organizations have already taken steps to embrace digitalization and enable a zero-trust network, their connectivity is still operating on incumbent network-centric approaches. Teams struggle to retrofit network-centric VPN technology to meet the needs of the modern user and the transforming business, but retrofitted approaches can prevent digitalization. It’s time to redefine secure remote access.

Cloud Native Databases with Kubernetes Persistent Storage on Dell EMC VxFlex family

whitePaper | December 19, 2019

Modern data center workloads have varying business value and characteristics for the workload and data that govern the performance, throughput, capacity, availability, data protection, and data services requirements. Shrinking IT budgets, push for greater efficiency, and consolidation and workload requirements have made it necessary for the underlying infrastructure to deliver high performance, scalability, resiliency, and most importantly -- flexibility. VxFlex family is an engineered system for Dell EMC designed on five super power principals to meet the key infrastructure requirements. VxFlex family delivers.

Dell EMC VxRail vSAN Stretched-Cluster Planning Guide

whitePaper | November 20, 2019

vCenter Server is the centralized platform for managing a VMware environment. It is the primary point of management for both server virtualization and vSAN and is the enabling technology for advanced capabilities such as vMotion, Distributed Resource Scheduler (DRS) and HA. vCenter scales to enterprise levels where a single vCenter can support up to 1000 hosts (VxRail nodes) and 10,000 virtual machines. vCenter supports a logical hierarchy of datacenters, clusters, and hosts, which allow resources to be segregated by use cases or lines of business and allow resources to be moved as needed dynamically. This is all done from a single interface.

Intel Page Modification Logging, a hardware virtualization feature: study and improvement for virtual machine working set estimation

whitePaper | January 7, 2020

Intel Page Modification Logging (PML) is a novel hardware feature for tracking virtual machine (VM) accessed memory pages. This task is essential in today’s data centers since it allows, among others, checkpointing, live migration and working set size (WSS) estimation. Relying on the Xen hypervisor, this paper studies PML from three angles: power consumption, efficiency, and performance impact on user applications. Our findings are as follows. First, PML does not incur any power consumption overhead. Second, PML reduces by up to 10.18% both VM live migration and checkpointing time. Third, PML slightly reduces by up to 0.95% the performance degradation on applications incurred by live migration and checkpointing.

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.
