FTP speed on blade servers
Iam new in Linux.
This is my problem. We have 9 servers in a blade enclosure , all running Linux , Redhat.
The ftp is very slow between two of these servers. We have 2 subnets invloved here. One of of the servers is on 10.17.3.X and all the other servers on 10.17.13.X . FTP ( 4 GB file) between servers on the same subnet is done in 2 minutes. But from servers on one subnet to the other subnet server, it takes hours !! . WE have involved HP and our n/w team and everything is ok on the n/w side / router / switch side. The Speed setting is also (correct 1GB FULL DUPLEX ) and we don't find any problem.
Now we are doubting the OS side ...Can some one help ?

Re: FTP speed on blade servers
I doubt that this is an OS thing. Sounds more like something in the network to me...
How are the two subnets linked together ?
Cheers,
Rob
P.S. You might want to let people know exactly which version of RedHat you're running just in case...

Re: FTP speed on blade servers
How did you determine this?
Can you post the output of netstat -ni of both servers?
Have you tried a packet trace/dump, for example, with tcpdump?

Re: FTP speed on blade servers
Here is the version details .
2.6.9-42.0.8.ELsmp #1 SMP Tue Jan 23 12:49:51 EST 2007 x86_64 x86_64 x86_64 GNU/Linux
We even did an ftp from outside the blade to the blade server and it went very well. Looks like it got something to do with the switch inside the Blade Enclosure. But , none of us are good in Linux / blade which is a new arrival in our environment.

Re: FTP speed on blade servers
You say you're using different networks, so unless they've got a very large subnet mask, the FTP has to be going through a router somewhere, which means it's probably leaving the blade enclosure and coming back in.
