kvblade seems dead, qoaed looks promising but is in its early stages in my 
opinion and aoeserver is the first time i hear. I will look into this.

Well, i've done optimisations like increasing network buffers and so on. But i 
didn't activated any hardware related optimisation. My goal is to achive good 
performance with standard hardware. I try to avoid a special kind of network 
card or a special kind of switch.

The only reason i'm looking forward to use aoe is because the disconnection of 
malfunctioning storage servers is better handled than with gnbd. gnbd (in "No 
Cluster" mode) waits forever if the server dies and i had to write my own 
programs to handle such a situation. aoe just gives i/o error, and that's 
what i want.
