Appliance XTM 2 (picture: Watch Guard)

WatchGuard at CeBIT shows two new additions to its portfolio of security appliances: The series XTM 2 is aimed at prices from 452 euros to companies with up to 50 employees. For companies with up to 1,500 employees, the models of the series XRM5 are from Euro 1388.

Both series include a WebBlocker for their equipment, for instance, can stop instant messaging and peer-to-peer connections. He also discovered and encrypted attacks. The danger of an attack on unified communications systems prevent them from a VoIP proxy.

The beginner series XTM 2 is composed of three models, the reference numbers 21 to 23 It has all the core features such as VPN connections for remote and mobile employees. Even a defensive shield against hackers, spam and virus is present. Compared with a pure firewall, the appliance offers according to the manufacturer by an additional layer to the application protection through proxies benefits.

The XTM Series 5 with four models (XTM 505, 510, 520 and 530) brings both more functionality and higher performance. For instance, the firewall throughput of the device up to 2.3 gigabytes per second. Tell a VPN throughput of up to 750 MB per second is possible. To operate, there are next to the web interface and a separate application and the opportunity to work at the command line. In addition, possible with the XTM-5 models, load balancing, and creating reports.

Scientific research to design clothes go solar charger no longer with Charger

When people travel, mobile phones, MP3 and other portable devices to find the power charge is an inconvenience. 25, reported the BBC, British researchers are designing a solar power charging coat, it can solve the problem.

According to reports, Japan’s Fujitsu and Germany’s Siemens AG’s joint venture companies with research centers in Cambridge, the center of British scientists has been how to study solar charging components “perfect” implant coat, pants or other clothing, so that the clothing can also transform solar energy into electricity. If you have such a future clothing, when you need in outdoor portable devices such as mobile phones or MP3 while charging these devices plug into the charging cable jack on the special clothing, and solar charging components to link your mobile phone , MP3 and other equipment will be able to once again “active” up.

According to the researchers, said David Pritchard, this solar charger will be mainly used in ski clothing, travel and emergency personnel clothing. In addition, this charge will also suit people who are environmentally conscious are attractive because of wearing such clothing, you can reduce energy consumption.

Made in China, the EU issued a consumer warning mobile phone charger

The Bulletin of the “AI & E” cell phone charger for the blister packaging, model TC-01, EAN code encoded as 8711252108599.

The phone charger short distance along the surface, not through pressure testing, do not meet “the EU Directive low voltage electrical appliances,” and the relevant EU standard EN60950.

At present, the Dutch authorities have ordered the goods from the market.

To this end, China Trade Remedy Information Network proposed the production and export of domestic enterprises attached great importance.

To the Opteron 6100-series for servers more than twice as fast as its predecessor, with six cores. AMD promotes energy efficiency and low prices. Chips for four-processor systems, there is no extra cost.

AMD has introduced the new Opteron 6000 Series processor with eight or zwolf cores for server systems. The new series, code-named Magny-Cours is that AMD faster, cheaper and more energy efficient, as the competition’s products.

The new processors with the serial number 6100 – the first series of the 6000-series – are in floating-point up to 119 percent faster than their predecessors to work with six cores. The integer performance is supposedly higher by 88 percent. The clock frequencies of the series amount to 1.7 to 2.4 GHz. Various energy saving techniques such as C1E sleep state to minimize power consumption.

The 6100 processors are both two-CPU as well as for four-CPU systems thinking. According to AMD chips for four-processor systems should not be more expensive than those for systems with two CPUs. The cheapest 6100-processor is the AMD Opteron 6128, 2.0 GHz and eight cores for $ 266. The best Zwolfkernprozessoren, the Opteron 6164 HE (low-energy, 1.7 GHz) and Opteron 6168 (1.9 GHz), cost $ 744. For the performance-top model 6176 SE with twelve cores and 2.3 GHz AMD demanded $ 1386.

It is expected that servers offer manufacturers such as Hewlett-Packard, Dell, and Cray systems soon with AMD’s 6100-processor.

Just recently, Intel had introduced a chip with six cores. The top model of server Xeon 5680 costs $ 1663.

So far, mostly spread processors with two and four cores. Chips with six cores are found mainly in expensive high-end servers. The more cores a processor has, the faster it works in theory. However, the software threads can be distributed to multiple cores in order to use them effectively.
