SGI has unveiled an integrated blade server system for SMEs. Origin 400 is to adapt the capabilities of the recent Origin products for large companies to the needs of smaller firms and branch offices.
SGI Origin 400 integrates 72 cores to six units (picture: SGI).
The Origin 400 can be used as Web servers, application servers, e-mail server and back-end database server. It supports the virtualization technologies, VMWare ESX, Citrix XenServer and Microsoft Hyper-V. Six blades, each with two sockets and 14 2.5-inch drives fit into a six-level units (6U) high chassis. The processor is Intel's Xeon chip yesterday imagined Sechskern 5600 are used. This results in 72 cores per Origin 400 system.
Intel positions the Xeon 5600 as a platform for customers who have moved server upgrades. It enables a high consolidation rate and brings with two safety features that will benefit the virtualization: Advanced Encryption Standard New Instructions (AES-NI) and Trusted Execution Technology (TXT).
The Origin 400 is available now. A price will not make SGI.
Apart from SGI have all the major server manufacturers yesterday extended its product range to include systems with Sechskern Xeon chips, including Dell with two blade servers (M710, M610), four rack servers, (R710, R610, R510, R410) and three tower servers (T710 , T610, T410), IBM with its x-series servers and HP, which even a gaming PC equipped with an Intel processor Sechskern: the HPE-180t. The server CPU alone costs $ 810 extra here, however VGP-BPL13 battery , VGP-AC19V13 , VGP-AC19V19 , dell 1691P battery , dell 3R305 battery , etc.
When the S1, S3 trigger conduction, S2, S4 shutdown, the DC power supply circuit for the: + → S1 → arc → S3, which was now half-wave in the electric arc current, DC and the wire is positive polarity, the arc stability , stove seam and deep penetration, through effective control of current, easy wire melting and metal transfer. When the S2, S4 turns on, S1, S3 shutdown, the power circuit for the - → S2 → arc S4, which were negative half-wave in the electric arc current, DC and the wire for the negative nature, the arc climbing along the wire, arc not stable droplet difficult transition, weld pool shallow arc along the wire with the climb to promote and reduce the arc welding wire melting on the pool's heating, the formation of shallow penetration characteristics. Thus, as long as the control group 2 alternately turn electronic components, switching the direction of arc current, and power elements by controlling the two groups on-time duration and the relative power ratio, frequency and can be obtained when the ratio of positive and negative half-wave power Adjustable AC and DC. In the welding process, welding parts according to the size of the request, select the appropriate welding current frequency and time of positive and negative half-wave power ratio, can form a suitable weld quality control, especially when welding sheet metal forming shallow penetration to ensure that melting does not appear pool formation failure phenomenon, to meet the requirements of welding quality.
DC arc welding inverter technology
Power electronic device performance improvement and development of inverter technology for the rapid development of the most basic material base, superior performance, a new emergence of power electronic devices will certainly lead to great development of inverter technology will inevitably lead to advanced AC-DC inverter welding power source in the application and development.
Successful trial since 1962 in China since the thyristor to ordinary Rectifying Tube and as the main variable injection technology, inverter technology has greatly developed, the device has greatly improved the quality of the derived type thyristor , the staff quick, two-way, turn-off and the inverter guide device has a faster development, product output increased significantly. Over the past 10 years, is designed with technology, testing, reliability and other aspects of the study, the device greatly improved the capacity of fixed, static and dynamic features to improve the afternoon. China has designed and developed a 1000A, 1200V, 30μs fast thyristor; 100A, 600V or more power switching transistor; 40,60 A, 1000V Fast Diodes above. In addition, 50,100 A high-power field effect transistors, IGBT in the early 90s began trial production. Meanwhile, frequency control, power supply, not between the sharp, electroplating power supply, resistance welding, arc welding power source, electron beam power, high frequency heating and heat treatment, electrochemical inverter has been widely used technologies and products, and have dozens of series and hundreds of specifications of such products. Including a unit capacity of 250,350 kVA thyristor converter; unit capacity of more than uninterrupted power supply units 1000kVA; 250kVA of IGBT inverter type resistance welding; 33kVA of IGBT inverter arc welding; 15,30 kVA of field-effect transistor-type arc welding inverter.
