According to a report from the China IT lab on October 18, HP proliantdlw.g5 (470064-635) is a 2U rack-mounted server launched by HP. IT uses Intel's next-generation 45nm process processor IntelXeonDP54052.0G, the 2U chassis makes it suitable for hosting and ensures a spacious internal space, which is good for both heat dissipation and expansion.

[It168 shopping guide] at the end of, the price of servers steadily declined. The price of two HP models fell, and the price of IBM and Dell models dropped by about RMB, lenovo and inspur models and prices are relatively stable. However, for high-end four-way models, local models need to be ordered.
I. Investigation Model
The main series of this survey include hp dl 580g7, IBM x3850x5, x3750m4, Dell r910 and r820, Lenovo r680g7, inspur nf8420m3, nf85
Obtain CPU speed
Run the following command in shell:
Sysctl-A | egrep-I 'hw. Machine | HW. model | HW. ncpu'
The output is as follows:
HW. Machine: amd64HW. Model: Intel (r) Xeon (r) CPU e5620 @ 2.40 GHzHW. ncpu: 8HW. machine_arch: amd64
The above information shows that the CPU is Intel Xeon quad-core and the frequency is 2.4 GHz.

Finally, a self-owned server is assembled. The configuration is as follows:

Total fee: 1500 + 2050 + 1170 + 1720 + 1450 = 7890 RMB
I wanted to build it into Xeon, but I bought this chassis very early on. The CPU fan is blown from the right. It is not suitable for general
This year is the year of Intel's Tick and the year of the comprehensive release of the Xeon E5 series. After the release of the latest Xeon E5-2600/1600 series in March 7, Intel released E5-2400/4600 in May 14. As a result, the E5 family's product line involves a single road, double Road, and four road, and various manufacturers have also followed up to release their own new products. Today we are going to
applications in the test script for improving the throughput performance of multi-core servers of the computer world lab are directly related to the performance of server NICs. One is static Web pages, and the other is ASP-based Web applications. Both applications share the same feature, that is, high concurrent requests per unit time, and massive data packets can be sent directly to the server through a dedicated test device, the server throughput can be immediately displayed.

very much.BGA packages have the following features:Although the 1.I/O pin count increases, the distance between pins is much larger than the QFP package, which improves the yield2. Although the power consumption of BGA increases, the electric performance can be improved due to the use of controlled collapse chip method welding.3. Low signal transmission delay, greatly improve the frequency of adaptation4. Assembly available coplanar welding, reliability greatly improvedThe more common form of e
Two days ago, I just published an article about the Chinese Xeon server: "enable a real machine package! 35 pictures of domestic Xeon 5600 servers, today I bring you an article on domestic haolong 6100 servers. Although it is not a real machine dismantling, there are a lot of content to present to you. If you choose AMD or Xeon, you may wish to compare them.

1 socket, core, thread(1) Socket is the number of slots on the motherboard to plug the CPU, that is, the administrator said "road"The chip manufacturer encapsulates one or more cores on a chip, called a socket. Assuming a slot has two cores, the motherboard is plugged into 2 slots, which is the 4-core system.(2) Core is what we usually call "nuclear", that is, dual-core, 4-core and so on. Single-core (Single-core) and multicore (multi-core) are also known as uniprocessor and multiprocessor(3) th
processor generates a special bus cycle to indicate the Enter stop mode. The hardware responds to this signal in several ways. The indicator light on the front panel lights up, generating an NMI interrupt to record diagnostic information, calling the reset initialization process (note that the binit# pin was introduced in the Pentium Pro processor). If non-wake events (such as a20m# interrupts) are not processed during the outage, they are processed after the wake-up shutdown event is processed

The processing capability of processor system is greatly improved, while the bus structure of server system is always IA-32 bus system.After the development of IA-32 server to 8-channel XEON server, the architecture has begun to become a bottleneck restricting the performance of the server.As a result, hp and Intel have been working together to develop IA-6
GHz Xeon/opteron, or 1.5 GHz Itanium 2 is about as fast as 4 GHz Xeon/opteron. CPU's operating speed also depends on the CPU's pipeline of various aspects of performance indicators.
Of course, the frequency and the actual speed is related, can only say that the clock is only the performance of the CPU one aspect, and does not represent the overall performance of the CPU.
