Virtualbox - Should I be using snapshots or clones for my purposes? Understanding Clones. Features | Documentation | Knowledge Base | Discussion Forums Prev Contents Last Next A clone is a copy of an existing virtual machine.
The existing virtual machine is called the parent of the clone. When the cloning operation is complete, the clone is a separate virtual machine — though it may share virtual disks with the parent virtual machine: see Full and Linked Clones). Changes made to a clone do not affect the parent virtual machine. If you want to save the current state of the virtual machine, so you can revert to that state in case you make a mistake, take a snapshot. Storage Optimization Techniques: Review the Benefits of Thin Provisioning. Introduction For several years Wikibon has been studying the benefits of virtualization and thin provisioning.
Our research spans dozens of detailed customer interviews and studies of many hundreds of customers over several thousand storage volumes. As well, our information has been validated through Wikibon's Energy Lab, which produces studies designed to assist customers in understanding the degree to which a product contributes to energy efficiency. Our objectives in conducting efficiency analyses are to identify not only the hardware impacts on issues related to utilization and energy consumption but more importantly the hard-to-quantify green software aspects of technologies. Wikibon Energy Lab Validation Reports are submitted to utilities such as Pacific Gas & Electric Company as part of an energy incentive qualification process where often outside engineering firms have validated our findings.
RAID Levels Explained. If you've ever looked into purchasing a NAS device or server, particularly for a small business, you've no doubt come across the term "RAID.
" RAID stands for Redundant Array of Inexpensive (or sometimes "Independent") Disks. In general, a RAID-enabled system uses two or more hard disks to improve the performance or provide some level of fault tolerance for a machine—typically a NAS or server. Fault tolerance simply means providing a safety net for failed hardware by ensuring that the machine with the failed component, usually a hard drive, can still operate. Fault tolerance lessens interruptions in productivity, and it also decreases the chance of data loss. The way in which you configure that fault tolerance depends on the RAID level you set up.

Program: Information Systems and Operations Management - University of Florida - Acalog ACMS™ The Department of Information Systems & Operations Management offers graduate courses leading to the Master of Science in Information Systems and Operations Management (M.S.ISOM); the Ph.D. degree in Business Administration; and a concentration in the Master of Business Administration (M.B.A.) program.
Minimum requirements for these degrees are available in the Graduate Degrees section of this catalog. Master of Science: The M.S.ISOM program provides computing, analytical, and application skills to be used in a business setting. The primary areas of emphasis in the M.S.ISOM program are business intelligence and analystics, information systems/information technology, and supply chain management. Requirements span traditional academic disciplines to produce a multiple-discipline focus. Typical positions for graduates include decision support specialist, information systems specialist, systems analyst, and logistic support specialist. Understanding unified storage architecture.
Storage Subsystem. [ The PC Guide | The PC Buyer's Guide | Designing and Specifying PC Systems and Components | Designing PCs: Structure and Subsystems | PC Subsystem Design ] Storage Subsystem The storage subsystem is the set of components that lets you permanently store data and programs on the PC.
While the data on most media can be changed or erased, the term "permanent" is used to contrast storage to the system memory, which holds data only temporarily--until you turn the PC off. Due to this permanence, the storage subsystem is a very important part of the PC; after all, the programs and data you use define the nature of your system. The storage subsystem is comprised of two basic types of hardware. Each of these storage devices talks to the PC over an interface, which is an internal communication channel that is used to convey information to and from the storage device.

Tape Backup vs Hard Disk Backup: What Does the Future Hold? I was frequenting Spiceworks earlier today and came across a post asking if “tape was legacy”.
I think what they were asking is whether backup to tape is the kind of legacy technology today that we see with VHS—there are still a few out there but the technology is on its way out. I realize that there are still advantages with tape when it comes to large volume backups and the ability to physically move the backup media to an offsite location.
