Today, the main character is the chassis. Many hardware firewalls are just PCs with multiple NICs. They only use UNIX operating systems and have customized a special chassis-a box, which is worth hundreds of times. The magic box that makes PC accessories worth hundreds of times is a 1U steel shell firewall chassis. Today, I chose a Firewall Router professional 1U chassis with a model of 1U1D360. The chassi

The Qianyi "Dragon ice five generations" 1U chassis adopts an innovative integrated design concept of "Chassis + radiator, A passive heat sink with a large heat dissipation area called "qianniu" is directly cooled by a powerful fan in the chassis, which greatly improves the air volume and heat sink area of the CPU cooling fan, it has produced epoch heat dissipation results. In addition, a black heat radiation and efficiency coating is sprayed on the s

With the in-depth R D of 1U chassis, the scalability of 1U chassis has been greatly improved compared with that of the original one. The original 1U chassis can only be placed with one hard disk, most of the current 1U chassis can be equipped with 2-4 hard disks, while the latest Masha storm 1U8DMS 10 wind turbine

Adaptive Slot (Intel Adaptive Slot), which can support the Pci-x 66MHz device or support the PCI-E x4 device by inserting a different transfer card, while the other slot is only pci-x 66MHz slots. With this riser, a full high Pci-x expansion card and a Pci-x expansion card can be installed in the 1U chassis. Install, maintain, and manage attachments such as rails are not included

-The 1l type is long int, And the 1u type is unsigned Int. For comparison, there is an implicit type conversion. In C, when a variable is long int, if the value range of long int can cover unsigned int, the variable of unsigned int is converted to long int; if the value range of long int cannot overwrite the unsigned int, the two variables are converted to unsigned long at the same time. Assume that Int Is a 16-bit value, while long Int Is a 32-bit

Today, the reporter recommended a Lenovo R510G6 server, which is a 1U rack server that is small and lightweight and suitable for small and medium-sized enterprises who do not have much office space. The latest price is 25500 yuan. Lenovo full R510G6S50501G73N soft guide this server uses a 64-bit dual-core Intel Xeon TM50503.0GHz processor, supports a maximum of 2, Today, the reporter recommended a Lenovo R510 G6 server, which is a

Today, we still need to use an excellent chassis to assemble an ultra-large capacity server-only a 1U high eight hard disk massive storage server, with a single hard disk capacity of 250 GB and a total disk capacity of 2 tb2000g )! The things I assembled may not be really NAS. The definition of the real NAS is too complicated. Many places do not comply with the definition of the official ocean. As long as this things can store massive amounts of infor

"The Meaning of U" "A shining debut. 1U a new generation of servers with thickness of only "--。 This sentence is often seen recently in ads on PC servers, but what does "U" mean here? In fact, U is a unit that represents the external dimensions of the server and is an abbreviation for the units, and the detailed dimensions are determined by the American Electronics Association (EIA), the industry group. The size of the server is required to maintai

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 talk about Dell's PowerEdge R620 server, a 1U

be applied in the next five to seven years. The company may develop new storage technologies in the next three years to store 1-byte data in 1U. The "racetrack" technology that IBM is considering to develop will pave the way for new storage devices. The new storage device increases the storage capability of home storage to the enterprise storage level. In the future, a portable player will be able to store 0.5 million songs.Hillsberg said that the

. In addition, it also has advanced thermal monitoring and cooling functions. With the rapid development of Internet IT industry, more and more small and medium-sized companies and even individual users have been involved in the server this familiar and fresh products. All along, the server in people's minds are considered to belong to the industry application of products, for individuals, is inscrutable and high-end. Many server Giants also note that the entry-level server this market, milli
