dual ethernet - dual speed
 

da li je moguće spojiti 2 ethernet porta na ploci sa 2 porta na switchu, ali da komputer ima jedan IP, tj. da se nekako postigne dupla brzina (npr. 2x100mbit)

???

Je, ali nemožeš dobiti 1 IP nego će svaki adapter imati svoj IP.
Sad, za brzinu nisam baš siguran, no ako planiraš prebacivati nešto priko mreže koristi FTP klijent i server po mogućnosti.

Moze, radi se o NIC teamingu / bondingu, no za takvu konekciju trebaju i switchevi koji to znaju izvesti na drugoj strani, ne da se izvesti s obicnim switchevima, kao sto i to ne mogu izvesti svi NIC-evi. Plus sto treba i dodatni SW.

U praksi je puno cesca varijanta failovera, tj. dvostruke konekcije prema dva switcha, a kod koje je samo jedan link aktivan.

malo sam googlo al nisam uspio naci konkretno rjesenje. Sa 2 IP-a brzina se ne povecava posto ce komp koristiti i dalje samo jedan adapter. Ali ajde ako jos neko zna nek kaze.
Ako ne, onda, da li bi se moglo ovo izvesti:
imam 2 kompa sa dual ethernetom. Da li mogu spojiti ta 2 kompa direktno jednim rj45 kablom ( i time postici 1gbit izmedju ta 2 kompa) a 2. port svakog od kompova spojiti na switch i time dobiti dosadasnjih 100mbit prema ostatku mreze?

Da si upisao "NIC teaming" u Google, prvi ili drugi link bi ti sve pokazali. :D

Mozes i ovo drugo. Samo pazi na adrese.

Na nekim nvidia pločama se znaju naći sljedeće điđe:

First Packet
Essentially, FirstPacket™ is packet prioritization — it allows users to set network data packets for applications and games that are more latency sensitive with a higher priority. For applications, FirstPacket™ technology gives users much more flexibility in how they may use their computers, allowing them to successfully do more things at the same time. For games, FirstPacket™ is about response time. FirstPacket™ delivers a predictable online gaming experience by treating gaming network packets more importantly than other network packets that can saturate a limited DSL or Cable broadband connection, such as FTP packets.



Any application that tends to use small packets and requires bounded end-to-end latency will benefit from FirstPacket technology. Any networked game, plus voice over IP, video over IP, and any interactive applications (network meetings, like WebEx) will benefit. The benefit is achieved by forcing the latency-tolerant applications to wait a bit longer to access the wire. This is a good trade-off, since the user has indicated that their preference is to have the latency-sensitive applications be given priority over the other applications.

DualNet
The nForce 5 offers two Gigabit Ethernet controllers on the same chip. These can be run independently as well as combined.

Teaming
Teaming allows the two integrated network connections to work together, appearing as a single network connection while providing up to twice the Ethernet bandwidth for transferring large amounts of data from home file servers to other PCs. Teaming also provides network redundancy through fail-over capability. By hooking up Ethernet connections to both gigabit ports, not only is performance increased by combining the two pipes, but the network is instantly protected against port or cable failure (such as a network wire getting kicked loose.)

TCP/IP acceleration
NVIDIA TCP/IP acceleration is a networking solution that includes both a dedicated processor for accelerating networking traffic processing and hardware-optimized software. TCP/IP acceleration provides deep levels of networking and traffic inspections at full-duplex gigabit Ethernet speeds. By offloading CPU-intensive packet processing tasks in hardware, TCP/IP acceleration delivers the highest system performance. If you use this feature however you cannot use any third

To podržava i ova iz mog siga ali moram priznat da se nisam nikad poigrao sa tim...

Jako zgodna stvar, "must have" kad su serveri u pitanju. Danas je prakticki failover team na dva switcha standardni setup svakog bolje slozenog servera...

Nakon divnog iskustva sa Nvidia softom (NF4 chipset, ActiveArmor/Firewall) nisam više nikad instalirao na komp bilo kaj a da se tiče neta, mrežnog prometa ili nedajbože nečeg naprednijeg a da dolazi iz Nvidie:)

Bacio CD koji sam dobio sa pločom, poškropio LAN portove svetom vodicom, pljuno triput na njih i uštekao maxtv u drugi LAN port.

Ozbiljno.

evo kolko sam skuzio, nic teaming je moguce ostvariti samo ako imam switch koji to podrzava (a moj 8 portni za 120kn ne podrzava :), tako da sam se odlucio za ovu drugu soluciju (2 kompa direktno + oba na switch).

Vjerujem. :D

Ne preporucujem to raditi osim ako nisu bolje Intel ili Broadcom kartice u pitanju. :D
