Intel network card issue purchase order to buy a Heart
intel network card, the first division from the intel web development Fast Ethernet controller starts about.
1995 年, 3com Fast Ethernet card market monopoly, was quite expensive Fast Ethernet card, intel point of view from their own strategy, originally developed Fast Ethernet card control chip. Development is completed, the main core chip code-named as the D100, the physical layer chip, code-named Phy-Tx. Create the appropriate network card, the main chip for the 82557, 82555 physical layer chip. I regret that the network card in one fell swoop 82557 3c905tx defeated the mainstream card, many computer makers to its wait and see attitude.
Intel did not give up, its network division in 1997, the PHY chip companies around the acquisition of Level-One, was launched around 97 November 82558,82558 B Ethernet controller chip, the physical layer chip and integrated with the main control chip, which is Phy-TX + D100 structure. The 82558 card finally the attention of the major computer manufacturers. Many companies such as IBM and HP, have increased with the intel's OEM orders.
1998 years or so, intel acquisition of Digital,
belstaff coat, Network R & D department (remember the icon marked with intel 21143 interfaces?). In the same year launched intel 82559 chip is intel 82559 82558 manufacturing process will be improved, then add PCI2.2 specifications and other function structure.
2001 年, intel 82550 series of Fast Ethernet chips introduced, which 82550GY is the flagship product, 82550gy more than ordinary 82559 Main IPSec, MDIx and HWI Alerting function. Early pro100 s card is to use 82559 + IPSec architecture or 82550ey single-chip solution. 82550 series of chips or the use of a kernel-based D100 and D100 on the increase in the function.
Fast network chip intel
Throughout the development of all network chips are used D100 kernel (in proset diagnostic information where you can see), that is, intel network card of each version little change in the network transmission performance,
belstaff leather, but more and more powerful heat smaller, more stable, that is to improve overall performance.
Buy Recommendation: 82550gy> 82550ey> 82559> pro100 ve> 82558> 82557.
buy intel network card, giving priority to the server version of the card, its durability and stability are high, the server version of the card can increase inequality in the purchase of recommended level. Such as priority to purchase 82559server not buy 82550ey.
If you have onboard intel Fast Ethernet, there is no need to use the other card was.
CSA bus and pci-e bus, intel network card, the performance is outstanding, not to pity.
second-hand parts vary widely, I can probably talk about ideas, we should be flexible with the meters.
Tips: D100 core built-3K +3 K the fifo buffer; other common cards, such as 3c905 series, 8139 series is built-2k +2 k the fifo buffer. AM79C971 AMD's chips are special, using a 32K +32 k external fifo buffer, the actual results as built-in buffer.
Intel's server version of network card, PCB board color in deep, dark green that is black and green colors, client version of the motherboard PCB board color is usually green. I was afraid of the students buy profiteers brush server network interface cards (not so evil, right), to see more of the time of purchase.
like eDonkey players earn points for attention, Intel cpu card when uploading data low occupancy rate, second to none in the industry, recommended Laolv with intel card.
RC82540EM is the intel network card used in the early pro/1000mt server chip, as long as careful adjustment of ADSL for home and do the server, good enough.
82558 chip does have two, that is 82558 (A-4) and 82558 (B-5), reflected on the chip marked 82558 and 82558B. 82558B launched two months later than 82558. NEC,
belstaff uk, Fujitsu, corega, PLANEX are produced with 82,558 chips, cards, original intel network card they use 82558B, 82558B chip than the 82558 chip multi WOL function, 82558B of the ESD Pass Voltage is + / - 2000 watts, 82,558 of the ESD Pass Voltage is + / - 1000 watts. Transmission performance of two chips, the same network.
82559c relatively rare in the chip,
belstaff sale, the chip is mainly used with an encryption chip manufacturing des earlier pro S series card. 82550 series of chips after the release, 82559c solution was eliminated. The network transmission performance and the same general 82559 chip.
Gigabit Ethernet
went on to say about the purchase strategy, high-end retail Gigabit LAN chip used by the intel, broadcom provide (altima acquired by broadcom), these two companies There is still one of only two original cards of the network equipment business. Gigabit chips by the end of National Semiconductor, marvell provide, marvell not the original card, but the German syskonnect marvell card can be seen as the original card. Low-end Gigabit Ethernet and VIA chip market occupied by the crabs.
Gigabit Ethernet interfaces are divided into the following ordinary pci, pcix, csa, pcie, performance from low to high. Gigabit Ethernet can not do ordinary pci gigabit complex work environment, the speed also is about four or five Fast, Gigabit Ethernet is a ########, do not recommend the purchase, pcix Gigabit pci card if inserted in the general trough, can not play All properties must be noted.
Gigabit Ethernet performance can be divided into four according to the overall Army. The first member of the Group is broadcom 5703, intel's pcie Gigabit Ethernet pro1000 pt, pf, and the pcie broadcom Gigabit Ethernet 5751. Pcie card companies can develop to three, ibm (?) All is not fuel-efficient lights, not to mention high-performance nature. It is noteworthy that 5703 card, is now the king of the performance of pcix card, network card to the other pcix left behind, the performance almost equal to pcie network card, is my recommended products.
The second is the all-Army intel network card, including 82544ei, 82545em, 82545gm, 82546gb, 82546eb and csa bus 82547ei, the performance of the members of this corps is very close to, the most notable feature is the overall performance under windows than the other manufacturers are higher than a length pcix card, at least 15% of the gap, but in a very mediocre performance under linux, we can see in the wintel network equipment firm alliance.
third group is led by marvell chip card, the main chip has yukon8010, National's DP83820BVUW, Altima AC1001, Realtek RTL8169, broadcom5700 and 5701, these cards mediocre performance in the windows environment was completely suppressed down intel card, but in the second go-ahead performance under linux Army.
fourth group is the use of pseudo-pci Gigabit Ethernet interface, the main chip has 82540em, 82541pi, some ordinary pci interface 8169 (netcore main push), marvell 8001 (tplink main push) , 8007 (dlink main push), via the gigabit chip (who ambition and Annette Yuen main push), the NIC card is best not to use as a server, home is still relatively affordable, which is intel's chips have optimal performance .

Intel 8255 * Introduction to Series NICs:
Intel (R) Pro/100 + Management Adapter
this card, generally applied to a workstation or personal computer in. In previous versions of Intel has repeatedly emphasized that the overall management capacity of its network card, but now they are just the You will find this card a lot smaller. Compared with other cards, Intel's Pro/100 + NIC smaller than the other 10% to 25%. This not only makes the card can be installed in the new ultra-thin PC, but also enhance the air convection inside the chassis. The Pro/100 + Management Adapter Intel is a commercial enterprise grade Zhang card. It supports all major management standards.
Intel (R) Pro/100 + Server Adapter
the card, usually used in servers, compared with Intel (R) Pro/100 + Management Adapter with higher stability and faster network transmission speeds.
one, Intel 559 Server Edition Description:
Intel 559 Server Edition, the use of intel 82559 chip, 10/100M adaptive, more than 2000 system comes with drivers (some say over WIN98 native driver), to support operating systems such as windows linux novell , a powerful Intel driver package can be downloaded, this is better than the 3com network card, 3com network card driver next it is quite difficult.
1, Intel 82559 features are as follows:
Media: 10Base-T/100Base-TX
Connector: RJ-45
Bus: 32-bit PCI
support the IEEE standard: 802.3,802.3 u, 802.2,802.1 p, 802.1Q, 802.1 GMRP
standard: PCI 2.2, WfM 2.0, ACPI 1.0, RWU, PXE
driver support: Windows 95/98/ME/NT/2000/XP/2003 - Linux, Netware, OS / 2, Packet Driver
; Features: Built-6K cache, PROSet Utility, Boot Agent, DCREATE.EXE
2, SERVER server version is more number of advanced features the following:
◆ support multi-port aggregation model;
◆ Bus-mastering technology with increased throughput and reduce the amount of CPU utilization;
◆ Support Hot Swap (with board support) replace the card without power;
◆ support a variety of standard network management, SNMP, etc.;
other advanced features can not list them, check out Intel official web presentation.
PROSET using INTEL's more than can be set to direct the formation of a virtual network adapter card, load balancing, link redundancy, FEC/802.3ad, GEC/802.ad, IEEE802.3ad and other senior Server Adapter features a cafe, a must tool for engineering and maintenance staff!
3, the server version of the original card comparison desktop several advantages:
1,
belstaff online, CPU share, lower than the desktop version, when the performance of the large flow is more evident.
2, network throughput than the big desktop network card, and a lower error rate, this is often the Internet to download APE, BT's friends have often experienced.
3, using the intel proset software can easily support two-card or multi card tied to work, redundancy can be achieved after the bundle, you can also load balancing and port aggregation.
especially on the soft route, diskless servers, Internet cafes when on the server on demand movies, and other than the 8139,530 TX network card, easy to use more than 1 times, there are several cards with the 8139 and 530 do soft route the customer (outbound bandwidth by the 2M ~ 20M, with machines ranging from 40 to 300), the card will replace the soft route Intel82559 Server Edition card, the immediate effect has played out - the original from time to time substitution, the game dropped calls, Internet hysteresis and other phenomena are immediately disappeared.
Since light from the hardware, can not distinguish between desktop and server version of NIC card, then there is no difference in the performance of it?
The answer is definitely different. Intel is the usual means: the good chips used in advanced products sell for a higher price,
belstaff jackets outlet, there will be some defects or due to manufacturing processes and other causes of the performance a bit weak, but still normal use of the chip positioning products, sold in the ordinary that the CPU from the Pentium and Celeron in to be fully reflected.
why we have a new version of the original server, network card, priced as high as 400 to 600 yuan, the desktop version for sale only 200 yuan in the situation. This we can ask the price directly to the Computer City, or to offer some online computer site to see to know.
In addition, many buyers through the use of contrast, found that the server version of the 82559 card, used in the router, when the server is indeed performed better than the desktop version, network transmission is also more stable. I have access to relevant information, that should be the server version of the desktop network card and network card in the number of concurrent connections between the processing power has caused. So why was confirmed only when used in an ordinary computer, the basic performance of the two feel the difference.
