Intel 82579v or Intel Gigabit CT desktop


Hi guys

i dont know much about networking, so i hope someone can help me

i do alot of file transferes to and from this pc (server on a small network) so reliability is a must, and ive grown fond of Intels chips

atm we have the following two network chips (82579v onboard, and intel gigabit ct PCIe)

Intel 82579v:

Intel Gigabit CT PCIe:

out of the two, which would outperform in reliability, stability, throughput and latency wise? (latency and throughput being the top two that need to be perfect)

i know there would be minimal difference, but i must use only one, and im confused as to which one?

i can see the 82579v is later than the intel gigabit ct pcie which is based on the Intel 82574L controller, but im not sure if that would make a difference.

Thanks for any input!

You ask a very interesting question. In theory, either network connection should be equally reliable and equally capable of fast file transfers. Other parts of your computer are likely to be more of a bottleneck than the network connections. You do have the advantage of being able to compare the performance of the two network connections using real-world file transfers and comparing the two. I suspect that you will not see a significant difference. However, if one does perform better for you, then go with the one that performs the best.

Are you using Windows or another OS? The Intel® Gigabit CT Desktop Adapter is an entry level server adapter and supports advanced features such as teaming. You mentioned the importance of reliability. If the built-in connection is not a management port, you could pair the two network connections into an Adapter Fault Tolerance team. Then if one connection should fail because of an internal fault, a bad switch port, or a broken cable, the other connection (which will be in standby) can take over. The teaming driver forms a virtual adapter that will add to the overhead of your networking, but I suspect that the additional overhead will not be noticeable on your file transfers. The User Guide and How do I use Teaming with Advanced Networking Services (ANS)? have more information on creating a team.

You might be able to tweak the advanced settings for lower latency or faster transfers. The default settings are settings that work well, and you do not have to change them. However, the settings are available and can affect performance. You can read more at Tuning Intel® Ethernet Adapter throughput performance.

I hope this helps.

thanks mark,

ill be teaming the two adapters for fault tolerance, using my pcie nic as primary,

im currently using windows, thanks for the links much appreciated
