The Popularity Of Windows Falls.

Experts from Net Applications noticed a tendency - the decline in popularity Microsoft Windows. But the transition of the majority of users on competing platforms - Apple Mac OS is premature, as the number of users of Windows, to date, more than 90%. However, a recent report of Net Applications, which is based on Internet users visiting the site can show koe some interesting statistics. Last month 7.94% of users accessing the internet via the operating system Mac OS X, an increase of 0.11% compared to the same statistics for May. If the development of Apple's operating system will move at the same pace, then this year you can expect a 10% market share of operating systems. With the pace in a few years may turn a serious struggle between competing platforms: Microsoft Windows and Apple Mac OS. The advantage of Apple also is the fact that the recent release of Windows Vista has not met expectations of users and shook their confidence in Microsoft, while "apple" is constantly improving its operating system and makes it all the more attractive to each user.

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.
