Difference between non-converged, converged and hyper-converged network storage.

Hyper-converged infrastructure (HCI) is a software-defined IT infrastructure that virtualizes all of the elements of conventional "hardware-defined" systems. HCI includes, at a minimum, virtualized computing (a hypervisor), software-defined storage, and virtualized networking (software-defined networking). [1] [2] HCI typically runs on commercial off-the-shelf (COTS) servers.

Contents

The primary difference between converged infrastructure and hyperconverged infrastructure is that in HCI both the storage area network and the underlying storage abstractions[ clarification needed ] are implemented virtually in software (at or via the hypervisor) rather than physically in hardware. [1] [2] Because software-defined elements are implemented in the context of the hypervisor, management of all resources can be federated (shared) across all instances of a hyper-converged infrastructure.

Design

Hyperconvergence evolves away from discrete, software-defined systems that are connected and packaged together toward a purely software-defined environment where all functional elements run on commercial, off-the-shelf (COTS) servers, with the convergence of elements enabled by a hypervisor. [3] [4] HCI systems are usually made up of server systems equipped with direct-attached storage. [5] HCI includes the ability to pool like systems together. [6] [7] All physical data-center resources reside on a single administrative platform for both hardware and software layers. [8] Consolidation of all functional elements at the hypervisor level, together with federated identity management, was promoted to improve data-center inefficiencies and reduce the total cost of ownership (TCO) for data centers. [9] [ need quotation to verify ] [10] [11]

The potential impact of the hyper-converged infrastructure is that companies will no longer need to rely on different compute and storage systems, though it is still too early to prove that it can replace storage arrays in all market segments. [12] It is likely to further simplify management and increase resource-utilization rates where it does apply. [13] [14] [15]

A virtual storage area network is a logical representation of a physical storage area network (SAN). A VSAN abstracts the storage-related operations from the physical storage layer, and provides shared storage access to the applications and virtual machines by combining the servers' local storage over a network into a single or multiple storage pools.

Infrastructure as a service (IaaS) is a cloud computing service model by means of which computing resources are supplied by a cloud services provider. The IaaS vendor provides the storage, network, servers, and virtualization. This service enables users to free themselves from maintaining an on-premises data center. The IaaS provider is hosting these resources in either the public cloud, the private cloud, or the hybrid cloud.

oVirt Free, open-source virtualization management platform

oVirt is a free, open-source virtualization management platform. It was founded by Red Hat as a community project on which Red Hat Virtualization is based. It allows centralized management of virtual machines, compute, storage and networking resources, from an easy-to-use web-based front-end with platform independent access. KVM on x86-64, PowerPC64 and s390x architecture are the only hypervisors supported, but there is an ongoing effort to support ARM architecture in a future releases.

In computing, virtualization or virtualisation in British English is the act of creating a virtual version of something at the same abstraction level, including virtual computer hardware platforms, storage devices, and computer network resources.

Cisco Unified Computing System (UCS) is a data center server computer product line composed of server hardware, virtualization support, switching fabric, and management software, introduced in 2009 by Cisco Systems. The products are marketed for scalability by integrating many components of a data center that can be managed as a single unit.

<span class="mw-page-title-main">Converged storage</span>

Converged storage is a storage architecture that combines storage and computing resources into a single entity. This can result in the development of platforms for server centric, storage centric or hybrid workloads where applications and data come together to improve application performance and delivery. The combination of storage and compute differs to the traditional IT model in which computation and storage take place in separate or siloed computer equipment. The traditional model requires discrete provisioning changes, such as upgrades and planned migrations, in the face of server load changes, which are increasingly dynamic with virtualization, where converged storage increases the supply of resources along with new VM demands in parallel.

VM-aware storage (VAS) is computer data storage designed specifically for managing storage for virtual machines (VMs) within a data center. The goal is to provide storage that is simpler to use with functionality better suited for VMs compared with general-purpose storage. VM-aware storage allows storage to be managed as an integrated part of managing VMs rather than as logical unit numbers (LUNs) or volumes that are separately configured and managed.

HP ConvergedSystem is a portfolio of system-based products from Hewlett-Packard (HP) that integrates preconfigured IT components into systems for virtualization, cloud computing, big data, collaboration, converged management, and client virtualization. Composed of servers, storage, networking, and integrated software and services, the systems are designed to address the cost and complexity of data center operations and maintenance by pulling the IT components together into a single resource pool so they are easier to manage and faster to deploy. Where previously it would take three to six months from the time of order to get a system up and running, it now reportedly takes as few as 20 days with the HP ConvergedSystem.
