DxEnterprise is multi-platform Smart Availability software built on patented technology that achieves the highest levels of availability for SQL Server instances and availability groups, containers, and apps across both Windows and Linux environments. It can be used to manage a variety of workloads at the instance level – as well as Docker containers. DxEnterprise is particularly optimized for native or containerized Microsoft SQL Server deployments on any platform and is also adept at management of Oracle on Windows. With DxEnterprise, organizations get advanced fault detection to minimize outages and complete instance mobility from any host to any host, anywhere.
DxEnterprise expands its Smart Availability capabilities to SQL Server availability groups (AGs) with DxEnterprise for AGs. DxEnterprise for AGs is the only tool on the market that enables SQL Server AGs to be made highly available within and between Windows and Linux nodes across any type of infrastructure, including support for containers - all without relying on cumbersome cluster orchestration technologies like Pacemaker or WSFC.
DxEnterprise unlocks these key benefits:
✔️ Highest levels of availability
✔️ Immediate 25%-60% licensing savings
✔️ Peak utilization and consolidation
✔️ Near-zero planned and unplanned downtime
✔️ Management simplicity
DH2i is a software provider with over 10 years of experience, helping customers around the world enhance their IT management and SQL Server capabilities with DxEnterprise.
KVM stands for Kernel-based Virtual Machine, which is an open-source virtualization technology that is embedded in Linux. KVM allows users to seamlessly transform their Linux system into a hypervisor that, in turn, will enable a host machine to run numerous, isolated virtual environments or virtual machines (VMs).
KVM is part of Linux. Users with Linux 2.6.20 or newer already have KVM. As KVM is already a component of the current Linux code, it automatically improves with every new Linux fix, feature, or upgrade. So KVM users are always current and up to date.
KVM automatically transforms Linux to a type -1 (bare-metal) hypervisor. All hypervisors need operating system components, such as a process scheduler, I/O stack, device drivers, memory manager, and more, to run a VM. KVM already has these components embedded, as it is part of the Linux kernel. Each VM is generated as a basic Linux proces,s which is maintained by the standard Linux scheduler, with dedicated hardware such as a graphics adapter, memory, disks, network card, and CPUs.
KVM Key Features:
KVM has many valuable key features. Some of its most useful features include:
-
Storage: KVM has the ability to use any storage protocol supported by Linux, including network-attached storage (NAS) and some local disks. Multipath I/O can be utilized to provide redundancy and improve storage. Disk images use thin provisioning, ensuring storage is used on demand. KVM is also able to use shared file systems, enabling VM images to be shared on multiple hosts.
-
Hardware: KVM is able to use a vast number of Linux-certified supported hardware platforms. As hardware vendors routinely contribute to kernel improvement, the most up-to-date hardware features are generally quickly added to the Linux kernel.
-
Memory: KVM effectively utilizes the memory management features of Linux, such as kernel same-page emerging and non-uniform memory access. The memory of a VM can easily be switched, supported by large volumes for improved performance, then backed by a disk file or shared.
-
Migration: KVM actively supports live migration so users have the ability to move any running VM between physical hosts with no downtime.
-
Security: KVM uses a blend of secure virtualization (SVirt) and security-enhanced Linux (SELinux) for improved VM security and isolation. SELinux determines security boundaries surrounding VMs. sVirt expands SELinux’s processes, permitting Mandatory Access Control (MAC) security to be used for guest VMs and preventing any manual labeling issues.
Reviews from Real Users
“The most helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so. KVM, as a native virtualization solution, is a complete and fully adequate system for small businesses that need to reduce costs, and also to make maintenance easier. “ - Georges E., Business Engineer and Consultant at All-Tech
“The most valuable feature of KVM is the hypervisor environment and how we can configure it with ease. Additionally, the interface is intuitive.” Sonu S., Senior Solution Architect at Micro Focus
