Harvester (HCI)
Harvester is a cloud native hyper-converged infrastructure (HCI) open source software. Harvester was announced in 2020 by SUSE. On 1 December 2020, SUSE acquired Rancher Labs who makes a product called Rancher that manages kubernetes clusters. As of v0.3.0 rancher supports integration with harvester to provide a "single pane of glass" (central web GUI) to manage both your infrastructure and workloads. Harvester Overview Architecture Bare Metal Harvester is a type 1 hypervisor designed to be deployed on bare metal servers. It can be manually installed using a ISO disk or USB install, or installed over the network via a PXE Boot server such as IPXE. OS Harvester uses the Elemental Toolkit to create a minimal cloud-init version of SUSE Linux Enterprise Micro 5.3 to provide an immutable Linux distribution to remove as much OS maintenance as possible. Virtualization Kubevirt is used on top of kubernetes to provide virtualization support. This allows harvester to r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Go (programming Language)
Go is a statically typed, compiled programming language designed at Google by Robert Griesemer, Rob Pike, and Ken Thompson. It is syntactically similar to C, but with memory safety, garbage collection, structural typing, and CSP-style concurrency. It is often referred to as Golang because of its former domain name, golang.org, but its proper name is Go. There are two major implementations: * Google's self-hosting "gc" compiler toolchain, targeting multiple operating systems and WebAssembly. * gofrontend, a frontend to other compilers, with the ''libgo'' library. With GCC the combination is gccgo; with LLVM the combination is gollvm. A third-party source-to-source compiler, GopherJS, compiles Go to JavaScript for front-end web development. History Go was designed at Google in 2007 to improve programming productivity in an era of multicore, networked machines and large codebases. The designers wanted to address criticism of other languages in use at Google ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VMware ESXi
VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware for deploying and serving virtual computers. As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel. After version 4.1 (released in 2010), VMware renamed ESX to ''ESXi''. ESXi replaces Service Console (a rudimentary operating system) with a more closely integrated OS. ESX/ESXi is the primary component in the VMware Infrastructure software suite. The name ''ESX'' originated as an abbreviation of Elastic Sky X. In September 2004, the replacement for ESX was internally called ''VMvisor'', but later changed to ESXi (as the "i" in ESXi stood for "integrated"). Architecture ESX runs on bare metal (without running an operating system) unlike other VMware products. It includes its own kernel. In the historic VMware ESX, a Linux kernel was started first and then used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dell EMC VxRail
Virtual Computing Environment Company (VCE) was a division of EMC Corporation that manufactured converged infrastructure appliances for enterprise environments. Founded in 2009 under the name Acadia, it was originally a joint venture between EMC and Cisco Systems, with additional investments by Intel and EMC subsidiary VMware.

IOPS
Input/output operations per second (IOPS, pronounced ''eye-ops'') is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). Like benchmarks, IOPS numbers published by storage device manufacturers do not directly relate to real-world application performance. Background To meaningfully describe the performance characteristics of any storage device, it is necessary to specify a minimum of three metrics simultaneously: IOPS, response time, and (application) workload. Absent simultaneous specifications of response-time and workload, IOPS are essentially meaningless. In isolation, IOPS can be considered analogous to "revolutions per minute" of an automobile engine i.e. an engine capable of spinning at 10,000 RPMs with its transmission in neutral does not convey anything of value, however an engine capable of developing specified torque and horsepower at a given nu ...

NVM Express
NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface Specification (NVMHCIS) is an open, logical-device interface specification for accessing a computer's non-volatile storage media usually attached via PCI Express (PCIe) bus. The initialism ''NVM'' stands for ''non-volatile memory'', which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCIe add-in cards, and M.2 cards, the successor to mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low latency and internal parallelism of solid-state storage devices. Architecturally, the logic for NVMe is physically stored within and executed by the NVMe controller chip that is physically co-located with the storage media, usually an SSD. Version changes for NVMe, e.g., 1.3 to 1.4, are incorporated within the storage media, and do not affect PCIe-compatible components such as motherboards and CPUs. By its design, NVM ...

Graphics Processing Unit
A graphics processing unit (GPU) is a specialized electronic circuit designed to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are efficient at manipulating computer graphics and image processing. Their parallel structure makes them more efficient than general-purpose central processing units (CPUs) for algorithms that process large blocks of data in parallel. In a personal computer, a GPU can be present on a video card or embedded on the motherboard. In some CPUs, they are embedded on the CPU die. In the 1970s, the term "GPU" originally stood for ''graphics processor unit'' and described a programmable processing unit independently working from the CPU and responsible for graphics manipulation and output. Later, in 1994, Sony used the term (now standing for ''graphics processing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

XCP-ng
XCP-ng is a Linux distribution of the Xen Project, with pre-configured Xen Hypervisor and the Xen API project (XAPI) working out-of-the-box. The project was born in 2018, following the fork of Citrix XenServer (now Citrix Hypervisor). Since January 2020, it is also part of the Linux Foundation, via the Xen Project. Name XCP-ng stands for Xen Cloud Platform - next generation. It is the successor to XCP, initially created as an Open Source version of Citrix XenServer in 2010. At that time XenServer was closed source, with XCP being the open source version containing a subset of features. As XenServer was open sourced in 2013, the XCP project was halted. Several years later when Citrix stopped delivering XenServer for free and via open source, the project was revived as XCP-ng. History In December 2017, Citrix announced that they would remove important features of XenServer Free edition and make them only available on paid tiers. Also, XenServer wasn't focused toward community b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
