Network Virtualization
Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time. Each channel is independently secured. Every subscriber has shared access to all the resources on the network from a single computer.
Network management can be a tedious and time-consuming...

Microsoft Hyper-V version 1.0
Microsoft Hyper-V version 1.0
Hyper-V version 1.0 is the virtualization feature created for Microsoft Windows Server 2008.
Hyper-V creates a virtualization layer above which multiple partitions can be run. The parent partition runs the hypervisor layer and allows for the creation and management of child partitions.
Administrators can create many child partitions, depending on available system resources. Each child partition can then run its own independent, isolated operating system, ...

Information Life Cycle Management (ILM)
Information Life Cycle Management (ILM)
Information life cycle management (ILM) is a comprehensive approach to managing the flow of an information system's data and associated metadata from creation and initial storage to the time when it becomes obsolete and is deleted. Unlike earlier approaches to data storage management, ILM involves all aspects of dealing with data, starting with user practices, rather than just automating storage procedures, as for example, hierarchical storage managem...

Storage Virtualization
Storage Virtualization
Storage virtualization is the amalgamation of multiple network storage devices into what appears to be a single storage unit. Storage virtualization is usually implemented via software applications and often used in SAN (storage area network), a high-speed subnetwork of shared storage devices, and makes tasks such as archiving, back-up, and recovery easier and faster.
A similar phrase, virtualization-aware storage, facilitates management and monitoring of storage ...

Portable Image Storage Device
Portable Image Storage Device
A small, portable storage device used for storing and viewing your digital images. The device is a portable hard drive in an enclosure that resembles handheld game consoles. The device usually offers USB and memory card readers as options for transferring your images directly to the device, as well as an LCD display for viewing the stored images. Depending on the manufacturer you may also have different controls for maneuvering through the images, such as forward...

Virtual Device Driver
Virtual Device Driver
In Windows systems, a special type of device driver that has direct access to the operating system kernel. This allows them to interact with system and hardware resources at a very low level.
In Windows 95, virtual device drivers are often called VxDs because the filenames end with the .vxd extension .

Storage Networking
Storage Networking
Storage networking is the practice of linking together storage devices and connecting them to other IT networks. Storage networks provide a centralized repository for digital data that can be accessed by many users, and they use high-speed connections to provide fast performance. It's most common to find storage networks in enterprise settings, although some vendors do sell networked storage products for consumers and small businesses.

Object-Based Storage Device
Object-Based Storage Device
Abbreviated as OSD, an Object-Based Storage Device is a device that implements the standard in which data is organized and accessed as objects, where object means an ordered set of bytes (within the OSD) that is associated with a unique identifier. Objects are allocated and placed on the media by the OSD logical unit. With an OSD interface, metadata is associated directly with each data object and can be carried between layers and across storage device files and ...

CLDC – Connected Limited Device Configuration
CLDC - Connected Limited Device Configuration
Connected Limited Device Configuration (CLDC) is the J2ME configuration for smaller handheld devices that are usually battery operated and low in memory with limited processing power and low bandwidth.
Most often the CLDC uses the K virtual machine, which is suitable for devices with 16/32-bit RISC/CISC microprocessors/controllers, and with as little as 160 K of total memory available -- 128 K of which is for the storage of the actual virtual mac...

Storage Management
Storage Management
The term storage management encompasses the technologies and processes organizations use to maximize or improve the performance of their data storage resources. It is a broad category that includes virtualization, replication, mirroring, security, compression, traffic analysis, process automation, storage provisioning and related techniques.
By some estimates, the amount of digital information stored in the world's computer systems is doubling every year. As a result, or...
