Subject Re: CS 4.0.0 - vpc deployment - why tier network limited to 200mb/s ?
Date Fri, 19 Apr 2013 19:54:40 GMT
Hello Chiradeep,

So with a VR running on a x5550 hexacore with not enough noisy neighboors
with a computing offering with 4 core, 4 gb ram, i can hope to run 20 vlans
with a total troughput of 2 gb max with 10 ip load balanced (each onto 3
vms) for a total amount of 3k connections (max, avg at 500 connect/s) and a
max bp of 200Mb/s (this bp is only for the lb ip) ? Or is it not enough
(hoping it is not impossible) ?


Thanks for your response.

Regards, Benoit.
