How In-Row Cooling Increases Data Center Efficiency
Increased data center densities enable operators to meet the demands of cloud and hyper-scale environments. As more power is consumed per rack, however, heat becomes a big problem. Most modern data centers have adopted some sort of aisle-containment solution to minimize the mixing of hot and cold air. More ...
Data Center Management Best Practices
The use of an integrated best practices approach to data center management involves efficient management of resources while still minimizing the costs of all the different interrelated competing factors that require attention. More ...
A Guide to Broadband Internet Connections
By this point, most of America already has a Broadband Connection to the Internet. But for those that have not yet taken the plunge, a world of benefits awaits you. Broadband can get you surfing up to 50 times faster than a typical 56K modem. More ...
What Are Pseudo-Wires?
Pseudo-wire is a mechanism used in networking and telecommunications to emulate various services using packet switched networks with technologies such as Ethernet, MPLS (Multi Protocol Labelled Switching) and IP (Internet Protocol). More ...
Network Storage Server Options
Although the need for storage available over a shared network is evident, it is not always clear which solution is right for your organization. There are a variety of options available, direct-attached storage (DAS), network-attached storage (NAS) and storage area networks (SAN). More ...
Computer Network Routers, Hubs, and Switches
The most common components on a computer network, not counting cables, are "routers", "hubs", and "switches". Many of these modules can be appear similar and there can be significant overlap in roles. This article explains the difference between these important network components. More ...
The IEEE 802.3 Ethernet Standards
The Institute of Electrical and Electronics Engineers (IEEE). The IEEE sets up committees to define industry standards. The IEEE 802 committee sets the standards for networking. The IEEE subcommittee 802.3 sets the standard for Ethernet. More ...
Network Topologies
The physical arrangement of the cables, computers and components is referred to as the networks topology. There are five basic topologies, bus, star, ring, mesh, and wireless. More ...
Fiber Distributed Data Interface
The Fiber Distributed Data Interface (FDDI) uses pulses of light and fiber optic cable to send signals with a 100 Mbps throughput over dual counter-rotating rings. More ...
Hubs, Switches and Routers - What's the Difference?
The terms "hub", "switch", and "router" are often used interchangeably and - in fact, the devices are quite different. Hubs are used to simply interconnect individual computers. Switches do the same more efficiently. However, routers interconnect different networks (as opposed to individual machines). More ...
What is FTTP, FTTH, FTTB, and FTTD?
Some FTTx such as FTTN (fiber to the node), FTTC (fiber to the curb) depend on copper wires for final connection to the customers premises which contrasts with FTTP. FTTP can be further categorized into FTTH (fiber to the home), FTTB (fiber to the building), etc. More ...
Frame Relay WAN Protocol
Frame Relay is WAN protocol and operates for LAN internetworking at data link layers. It is a packet-switched technology designed for swift digital transmission of data. Data integrity is not guaranteed and packets are discarded during network congestion. More ...
Trunking, Bonding, Aggregation; What Does it Mean?
Each port on a network switch would be connected to one network device, such as a computer. But to connect a server you need higher bandwidth. For this purpose you could combine multiple Ethernet channels into one. More ...
