High performance affordable low price 1U server

Super-Yi recently launched a 120X (2802VT) 1U rack server, economical price but provide enterprise-class performance and reliability. Mainly located in E-commerce, file printing, general server, domain Controller/firewall/proxy server, mail server, including database front-end server applications.

The
machine uses the Intel Xeon processor, up to the 3.6ghz,800mhz front side bus, the chipset uses Intel E7320+intel 6300ESB, the motherboard has 6 DIMM slots, and the maximum support 12GB ECC registered Ddrii 400 memory, Motherboard South-South integrated SATA controller, support HOSTRAID0.1, motherboard integrated dual Gigabit Ethernet card, 1 full height 64-bit/66mhz PCI slot or 1 full height PCI x8 slot, chassis with 2 hot-swappable SATA disk bits, 400W Etasis 1U Server dedicated power supply.





120X (2802VT) external size ("x1.68"), the use of the rails provided by the rail can be conveniently installed on the standard rack, the equipment to provide you with a strong service, effectively save your precious space. Most of the area on its front panel is occupied by the hard drive bits and the optical drive, which includes a total of 2 hard disk bits. The optical drive has its own LEDs indicating its working status, and the hard drive has LEDs to indicate whether it is read or write or idle. A little space on the upper right side of the front panel is the position of various LEDs and connectors, which includes a power switch and a reset switch; Refer to the following figure:


server after the panel can see the power and the I/O interface, power is the use of the server-specific 400W etasis power supply, the back panel interface has 2 PS2 interface, 2 USB interface, a serial interface, 1 VGA interface and 2 Gigabit RJ-45 network interface, 1 Power interface, On the right you can also see an extended slot with a full length. See figure below:

This server supports remote management of the server IPMI1.5, in addition to the following features:





: Switch On demand, realize intelligent power distribution





Direct reduction of heat source power is the most direct way to solve the problem of heat dissipation. The next-generation Xeon processor at 3.4GHz or above will support on-demand switching technology (Demand Based Switching, DBS) to dynamically adjust the processor's frequency according to the load level of the system's tasks, allowing the CPU to work at full speed when the data needs to be processed efficiently. In the case of simple tasks (low processor occupancy), you choose to reduce the operating frequency (16 reduction levels are defined in ACPI 2.0) to control idle processor power. This power-control technology from the notebook mobile processor will also play an important role in the server field. The DBS technology has a significant effect on solving the system cooling problem and reducing the power consumption of the whole machine. According to Intel's test data, using DBS technology can save more than 28% of the energy consumption. The reduction of power consumption greatly reduces the pressure of the cooling system.





Second: Redundant intelligent fan, the source of thermal power





Currently, almost all servers use air-cooled cooling system. In this system, the position of the fan as the source of the cooling power is undoubted. To ensure a good cooling of the host, 4 fans are designed between the hard drive module and the processor. Because of the use of hot-plug technology, make maintenance and management more simple and convenient; 4 fans are redundant, even if some fans are in trouble, the remaining fans will still be able to run as usual, to maximize the stability of the system.





at the same time, the fan also uses intelligent design, all parts of the system have temperature sensors, these sensors to detect the temperature of each part of the system, and data transmission to the BMC and bios, in advance, set several temperature threshold and corresponding system fan speed corresponding table, When the sensor detects that the current temperature is higher than a preset, the system fan speed will be adjusted to meet the system cooling requirements; When the power dissipation reduces the system temperature to the next preset value, the system fan speed adjusts slowly to reduce system noise.





Three: Set guide wind path, centralized control of merry





The excellent duct design has been the specialty of IBM, HP, Dell and other international server vendors, but we also feel it in the custom 120X (2802VT). According to the internal structure of the chassis and fan arrangement, the design of the wind shroud, apparently through the research and development personnel repeatedly, through the accurate measurement of the system airflow pressure and the direction of the design of the final solution. The shroud is positioned at the back end of the fan and tightly covers the key components such as the processor to form a set guide wind path. The wind path will diverge and move to irregular airflow, thus effectively increasing the airflow pressure and standardizing the air flow, the central airflow is the key heat dissipation components (such as: processor, memory, power, PCI card) cooling. If there is no guide wind path, airflow flow is not unique, there is no focus, part of the airflow from the chassis gap, side hole outflow, or even backflow, so the system is extremely detrimental to heat dissipation.





Four: Less cable design to ensure smooth air duct





for the rack-type server, due to space constraints, the design of the air duct is very exquisite. In the Customizer 120X (2802VT), all the cards are arranged in the direction of the airflow, eliminating the card for the air of the obstacles to maximize the smooth flow of the air; On the other hand, considering the inside of the chassis messy line, such as data lines, power lines, signal lines and so often will seriously obstruct the wind tunnel, affect the direction of the system cooling airflow, so that the heat dissipation, 120X (2802VT) using less cable design concept, as far as possible to design the interconnection between the circuit board, eliminating the cable connection; can not avoid the data cable connection, the use of standardized way to go along the chassis side wall order, not only neat and beautiful, More important is not to block the system cooling air duct, to ensure effective cooling system.
