APA question

Trojan36 — Thu, 23 Jul 2009 14:17:48 GMT

Can I use the APA software to gang a 4-port NIC with the two internal NIC ports for greater bandwidth? I have a rx2660 server.

thx in advance

yes you can technically but with a server like rx2600 series, are you sure that you have enough CPU capacity to handle the data coming in from such a large pipe, considerin all 6 ports are gig-e speed ports ? It might be a little overkill. My 2 cents

Shalom,

Yes you can do what you desire. That is what APA is designed for.

You may need to do some work on your Cisco switches to make it work right.

Apart from the aforementioned caveats, keep in mind that it is the "aggregate performance under a single IP" that is greater, not the performance of a single flow, where flow is defined based on the packet scheduling algorithm you select as being:

traffic to the same MAC
or
traffic to the same IP
or
traffic to the same TCP or UDP port numbers
etc etc

So, you can aggregate the interfaces, but don't expect any one flow/connection to run faster than 1G.
