Hyper-converged Infrastructure
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). HCI typically runs on commercial off-the-shelf (COTS) servers. The primary difference between converged infrastructure and hyperconverged infrastructure is that in HCI both the storage area network and the underlying storage abstractions are implemented virtually in software (at or via the hypervisor) rather than physically in hardware. 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. Description Hyperconvergence evolves away from discrete, software-defined systems that are connected and packaged together toward a purely sof ...

Software-defined Data Center
Software-defined data center (SDDC; also: virtual data center, VDC) is a marketing term that extends virtualization concepts such as abstraction, pooling, and automation to all data center resources and services to achieve IT as a service (ITaaS). In a software-defined data center, "all elements of the infrastructure — networking, storage, CPU and security – are virtualized and delivered as a service." SDDC support can be claimed by a wide variety of approaches. Critics see the software-defined data center as a marketing tool and "software-defined hype," noting this variability. In 2013, an analyst projected that at least some software-defined data center components would experience market growth. The software-defined networking market is expected to be valued at about US$3.7 billion by 2016, compared to US$360 million in 2013. IDC estimates that the software-defined storage market is poised to expand faster than any other storage market. Description and core componen ...

Intelligent Workload Management
Intelligent workload management (IWM) is a paradigm for IT systems management arising from the intersection of dynamic infrastructure, virtualization, identity management, and the discipline of software appliance development. IWM enables the management and optimization of computing resources in a secure and compliant manner across physical, virtual and cloud environments to deliver business services for end customers. The IWM paradigm builds on the traditional concept of workload management whereby processing resources are dynamically assigned to tasks, or "workloads," based on criteria such as business process priorities (for example, in balancing business intelligence queries against online transaction processing), resource availability, security protocols, or event scheduling, but extends the concept into the structure of individual workloads themselves. Definition of "workload" In the context of IT systems and data center management, a "workload" can be broadly defined as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Infrastructure
Dynamic Infrastructure is an information technology concept related to the design of data centers, whereby the underlying hardware and software can respond dynamically and more efficiently to changing levels of demand. In other words, data center assets such as storage and processing power can be provisioned (made available) to meet surges in user's needs. The concept has also been referred to as ''Infrastructure 2.0'' and ''Next Generation Data Center''. Concept The basic premise of dynamic infrastructures is to leverage pooled IT resources to provide flexible IT capacity, enabling the allocation of resources in line with demand from business processes. This is achieved by using server virtualization technology to pool computing resources wherever possible, and allocating these resources on-demand using automated tools. This allows for load balancing and is a more efficient approach than keeping massive computing resources in reserve to run tasks that take place, for example, onc ...

Eweek
''eWeek'' (''Enterprise Newsweekly'', stylized as ''eWEEK''), formerly PCWeek, is a technology and business magazine.

Total Cost Of Ownership
Total cost of ownership (TCO) is a financial estimate intended to help buyers and owners determine the direct and indirect costs of a product or service. It is a management accounting concept that can be used in full cost accounting or even ecological economics where it includes social costs. For manufacturing, as TCO is typically compared with doing business overseas, it goes beyond the initial manufacturing cycle time and cost to make parts. TCO includes a variety of cost of doing business items, for example, ship and re-ship, and opportunity costs, while it also considers incentives developed for an alternative approach. Incentives and other variables include tax credits, common language, expedited delivery, and customer-oriented supplier visits. Use of concept TCO, when incorporated in any financial benefit analysis, provides a cost basis for determining the total economic value of an investment. Examples include: return on investment, internal rate of return, economic value ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct-attached Storage
Direct-attached storage (DAS) is digital storage directly attached to the computer accessing it, as opposed to storage accessed over a computer network (i.e. network-attached storage). DAS consists of one or more storage units such as hard drives, solid-state drives, optical disc drives within an external enclosure. The term "DAS" is a retronym to contrast with storage area network (SAN) and network-attached storage (NAS). Features A typical DAS system is made of a data storage device (for example enclosures holding a number of hard disk drives) connected directly to a computer through a host bus adapter (HBA). Between those two points there is no network device (like hub, switch, or router), and this is the main characteristic of DAS. The main protocols used for DAS connections are ATA, SATA, eSATA, NVMe, SCSI, SAS, USB, USB 3.0 and IEEE 1394. Storage features of SAN, DAS, and NAS Most functions found in modern storage do not depend on whether the storage is attached dir ...
