Monitor NEC CRV43

Current conditions favor the development of large-format models of monitors and televisions. More recently, in the lives of people I came to 16: 9 format, and now the company is NEC CRV43 Series monitor with an aspect ratio of 32:10, with a diagonal of this monitor is 43 inches. This product is intended primarily for professional artists, designers and creative people. While enjoying your movies and videos on this screen is also quite nice. Screen resolution is 2880h900 pixels, and a concave screen is its main feature. At the same time, this feature does not affect the use of NEC CRV43 at home. The brightness of the monitor is 200 cd / m2, contrast ratio at 10,000 to 1. Monitor from NEC is equipped with modern inputs HDMI and DVI-D, as well as a USB port for connecting a variety of storage devices. Since the product has only recently appeared on the market, its price is enough high and is about 217 thousand rubles.

NUMAFlex-New Computer Architecture SGI

Silicon Graphics introduced the public a series of servers and workstations with the new architecture, with which the company hopes to regain lost ground in the market of Unix-based systems. The architecture NUMAFlex, embodied in the Origin 3000 servers and workstations swelling 3000, the computer consists of modules that SGI He calls the "bricks» («bricks»). The modules are installed in a common rack and connected to a patented high-speed bus, developed by SGI. The architecture allows you to expand the system to sootvegstvii to your needs by adding new functional units. The minimum configuration of a server or workstation 3200 Series includes the C-brick - the processor module with a 400-MHz MIPS R12000 processor and 512 MB ​​of memory and I-brick - I / O module two disk drives Fibre Channel, DVD-ROM drive and five slots PCI. As standard, the processor module will contain two processors (the maximum number - 8), 16 GB of memory and 17 I / O connectors. Model 3400 Series can accommodate up to 32 processors and have 64 GB of memory and 88 I / O connectors. Older model series 3800, according to SGI, provide up to 512 processors, 1TB of memory, 1528 I / O connectors and thousands of gigabytes of disk space. SGI will release a processor modules based on the Itanium processors and subsequent Intel, as well as on the basis of the CPU R14000 and R16000 and future dual processor MIPS. For the new architecture of the modules produced P-brick, supporting up to 12 PCI-devices, G-brick with the graphics processor SGI Infinite Reality Graphics Engine, and the unit of disk space and a binding module "processor-memory". In computers based on MIPS processors will use the operating system Irix, and models based on the Itanium - Linux, although the latter only supports up to 16 processors, unlike Irix, which is designed for 512 processors or more. Prices of new systems will start at $ 50 thousand ., although the most probable price a minimum configuration will be about $ 100 thousand. According to experts, computers for computing tasks, such as modeling of gene expression patterns, will cost about half a million dollars, computers B tems aided design - two million, and powerful systems for university computing centers - to $ 10 million.

What Is Fibre Channel?

Fibre Channel (FC) is a specification of high-speed connections of electronic devices, which allows you to create a flexible configuration. FC has the properties of network technology, such as Ethernet, and tires, such as SCSI. It can be used in a network for connecting multiple systems and reservoirs. Any system can access any storage device. This means that the amount of data available within the enterprise as a whole increases. Speed ​​high: today Fibre Channel is capable of transmitting large amounts of data at a speed of 100 MB / s (full duplex - 200 MB / s). Specifications Fibre Channel protocol includes five levels, of which the first three are physical levels. Specifications these three levels approved as standard. Specifications levels 4 and 5 (FC3 and FC4) developed. Nevertheless allowed some freedom of interpretation, which is used by manufacturers to create specific functions of its own products and gain an advantage over competitors. This behavior leads manufacturers, in particular, to the fact that a single standard for the administration of FC-based infrastructure has not yet appeared. Fibre Channel can be used in five different classes of service and is being implemented in three topologies. • Class 1: Acknowledged Connection Service for large files and full bandwidth capacity; • Class 2: Acknowledged Connection Service for clusters, networks and OLTP; • Class 3: Unacknowledged Connection Service for storage, networking, broadband; • Class 4: Fractional Bandwith Service for real-time audio / video; • Class 5: Service for unicast video broadcast (one to many). To connect the storage subsystems and robotic tape libraries used Class 3, for synchronous replication of data in clusters applicable class 2. In a circuit topology implemented "point to point" , ring topology FC-AL (Fibre Channel Arbitrated Loop) and Switched Fabric. Topology "point-to-point» Fibre Channel provides the easiest way to connect the two nodes. This delivers full bandwidth of 100 MB / s, but the scalability is limited. FC-AL is a ring topology like Token Ring and FDDI. It brings together up to 126 nodes in a single ring, and allows you to share 100 MB / s bandwidth. In addition, it provides good scalability of the system. Topology Switched Fabric permits the consolidation of 16 million units, and forms the basis for connecting the other rings and knots.

PCI Express Cards

Bus PCI Express bus is a modern, designed to replace all of its used tires, including PCI and AGP. The main difference - the sequence data. Following the example of Serial ATA expansion card can now be connected without turning off the computer's power, and to use other, no less pleasant features that take their roots in the specification of the tire USB. The creation of the company does PCI Express PCI SIG: PCI Special Interest Group. Modifications tires PCI Express: Express x1 -pci -pci Express x4 -pci Express x8 -pci Express x16 -pci Express x32 voltage line all the same and equal to 0.8 B; capacity of 200Mbit / s, 800Mbps / sec, 1600Mbit / sec, 3200Mbit / sec 6400Mbit / sec

Utility WOT - Excellent Protection For Your PC

Utility with the acronym WOT is a free add-in Firefox and Internet Explorer from the company Panda Security in Spain. The main advantage of the utility WOT is a warning about the threat from the Internet, before you go to a site containing dangerous information. In addition, it protects not only against viruses, but also from scams that can steal passwords, keys, personal data will prevent the purchase of suspect in store. By installing this utility, you can evaluate yourself any sites with a special button which is integrated in the panel of your browser. In the search results, the system displays user ratings. Depending on the reputation of the site, changing the color and icons, thus: a reliable site is displayed in green, requiring attracted the attention of the sites of yellow and potentially dangerous to visit the site is highlighted in red. The utility WOT is a great helper for anti-virus, because in some cases it will not have to be involved in protection.
