Strange network bottleneck
Hi:
I have an enclosure HP BLC7000, my blade servers are BL465, interconected with gigabit switches descripted as "HP GbE2c Ethernet Blade Switch for HP c-Class BladeSystem (410917-B21)", on my servers the link speed says 1Gb on the status property, but doing tests, the only i can get is 100bmps,
i´m doing tests transferring files between blades running on the same enclusure and switches, to and from the SAN so i´m sure i can get more, i also tested with ftp "get xfilename NUL" command to stress it but the results are the same, when i transfer files from my local discs to the san y get 250mbps, so the hard drives are not a bottleneck, i wonder if any of you are having similar issue, thanks in advance for any advice
At this time the gig switches are not configured so i can not get cli or other management info, but next sunday i will assign ip address to the swicthes in order to manage them, i suspect that there is some thing wrong in there.

Well,
actually the switch says 1000 as speed, but when i upgraded nic drivers to the last on the blades, and set them to 1000 full, the trafic between blades goes fine, with performance about 400 mbps but this is because a disk bottleneck, now, o have the 100mbps limit in my VMs on hyper-v rtm, but that´s another story...
thanks
