Domestic 2U rack-type Server Shopping guide low-priced products

In contrast to dual dual-core 1U servers, the mainstream 2U server system, in addition to the same chipset platform, the other aspect is the 1U extension version, the main expansion is as follows--the number of memory slots and the largest http://www.aliyun.com/zixun/to support Aggregation/17968.html "> Memory capacity has been expanded, generally twice times or more of 1U products; The number of disk racks has been expanded, most of the 1U can only support 2-3 hard disks, up to 4, and 2U server will have the number of hard disk bits expanded to 6, Even support 8 and the major brands of 2U products will be hot-swappable SAS hard drive as the mainstream standard configuration, because the support of multiple hard drives to the 2U server to achieve advanced raid combination of the reality, so the use of hot-plug hard drive more consistent with the RAID array fault-tolerant requirements; Larger space also gives the server the power to use redundancy, and the internal heat dissipation problem is better than 1U solution. In fact, objectively speaking, the domestic 2U server in the design and IBM HP of these products there is a certain gap, the domestic may look more like a assembled products, of course, this advantage is also the price of good control,

Based on the above analysis, we introduce two of such applications in line with the server for your reference:

Dawn I620r-f1

    as Intel releases the next generation of Woodcrest for server-used processors, last year's Dawn also followed Intel's footsteps, upgrading the I-Series server product line to fully transition to a dual-core product platform for its original single-core products. Dawning I620R-F1 is such a dual-core dual-Path server: The use of 2U rack-style structure, standard a standard 1 Xeon 5110 duo processor, core frequency 1.6GHz, dual-core sharing 4M two cache, the largest support 2 CPU, support 64-bit memory expansion technology. With Intel's latest 5000P chipset, it provides a 1066MHz or 1333MHz-frequency front-end bus with a maximum system bandwidth of up to 21gb/s. Equipped with 2*512MB ddr2-533 FBD memory, maximum support memory capacity of 32GB, can provide up to 17gb/s memory bandwidth, 8 memory slots.

    Storage, with 1 73*2GB SCSI hard drives, integrated host RAID0/1/5/10/50, support for online recovery RAID array, and hard drive failure to ensure data security. Provides 6 hot-swappable disk bits, integrates dual gigabit Ethernet cards, and 6 expansion slots. Standard 1 power supply, power 600W. On the network side, integrates two Intel 82.563 million gigabit network adapters to support the wake on Wol-wake (Lan) feature.

    Some of the technical features of this server:

    in the network card, it supports multiple network card redundancy, the system is normal to share network traffic, when one of the network card problems, Automatically switches the work that it is burdened to other network adapters.

    Hardware: High performance BIOS, virus protection and recovery capabilities, advanced memory fault tolerance, support for memory mirroring and hot standby, automatic power detection, detect internal DC power quality at any time, and find problems in time to alarm.

    system aspects: Optional dawning intelligent hardware monitoring system, providing system internal temperature, fan speed, DC power supply voltage and other work status information display. Automatically record the time and log information of the host's failure to stop working, help to analyze the cause of the failure, support the power state memory function, when the external power supply system fails to make the server power off, it will automatically open after the power supply is restored to normal, and continue to provide services without system administrator management Support Intelligent dynamic Adjustment fan speed function, fan speed with the system temperature dynamic adjustment, effectively reduce the system noise and power consumption.

    this server as a new Generation IA architecture server adaptable to a variety of task environments can be applied to telecom, finance, taxation, government, military and school industries, as well as office automation systems, small and medium sized central servers such as database servers.
