Data centers are comprised of a high speed, high demand networking communication systems capable of handling the traffic for Storage Area Networks (SAN), Network Attached Storage (NAS), file/ application/web server farms, and other components located in the controlled environment. The control of the environment relates to humidity, flood, electrical, temperature, fire controls, and of course, physical access. Communication in and out of the data center is provided by WAN (Wide Area Network), CAN/MAN (Metro Area Network) and LAN (Local Area Network) links in a variety of configurations depending upon the needs of the particular center. A properly designed data center will provide availability, accessibility, scalability, and reliability 24 hours a day, 7 days a week, 365 days per year minus any scheduled downtime for maintenance. Telephone companies work for 99.999% uptime and the data center is no different. There are two basic types of data centers: corporate and institutional data centers (CDCs) and Internet Data Centers (IDCs). CDCs are maintained and operated from within the corporation, while IDCs are operated by Internet Service Providers (ISPs). The ISPs provide third-party websites, collocation facilities and other data services for companies such as outsourced email. Critical data centers are monitored by a NOC (Network Operations Center) which may be in-house or outsourced to a third party. The NOC is the first place outages are realized and the starting point for corrective action. NOCs are generally staffed during the data center’s hours of operations. In 24 x 7 data centers, the NOC is an around the clock department. Equipment monitoring devices will advise the NOC of problems such as overheating, equipment outages, and component failure via a set of triggers that can be configured on the equipment or via a third party monitoring software which can run over all of the equipment.
Q. What is the 40GbE max supported distances? A. The IEEE 40GBASE-X standard describes the following: 40GBASE-SR4 supports up to 100m on OM3, and 150m on OM4. There is no support for OM2 or OM1 (these are considered legacy). 40GBASE-LR4 supports up to 10km on 9um SM fiber (same fiber used for 10G single mode […]
What is a Point-to-Point (P2P) Cabling System? The point-to-point (p2p) cabling system is constructed with direct connections. Patch cables are used to connect one device such as a router, switch, server or storage unit directly to another device. As the number of connections in a data center increases due to normal growth, a point-to-point cabling system is […]
When it comes to IT infrastructure decisions, including the choice of where to host business-critical applications, enterprises are amid a reality check. Enterprise IT leaders know it’s time to move on from the days when computing models were built exclusively on mainframe and client server computing models, but they’re still working out what the next model […]
