Re: Re : serveriron predictor

Use the reponse-time predictor.

It's the best choice in your situation. here is what I found :

"Response time only – The ServerIron selects the real server with the fastest response time."

Hi
Surya, 

   

First
off, many thanks to your reply.  

   

These
are the only options for the predictor command on our serveriron; 

   

 
least-conn 

 
least-local-conn 

 
least-local-sess 

 
local-weighted 

 
response-time 

 
round-robin 

 
weighted 

   

The
"response-time" is the one close to your suggestion. But its not
"least response time",  which I guess means the opposite - serveriron
will then select the real server with the fastest response time. That looks
good for our setup. In addition, you mentioned in your email below some kind of
"combo" predictor. Can I use response time plus weighted here? That
is based on the above options we have on our box. If yes, can you give me
sample config? 

   

Regards, 

Reynald

  Do you have some kind of "least response time"
  of "fastest" predictor available ?

  

  Otherwise Weighted round robin (or weighted least conn) may be a good choice
  if you tune the weight according to the hardware specs of the servers.

  Hello, 
    
  Just trying to
  find what's the best predictor to use if you have a group of servers that has
  differect hardware specifications (e.g. processor, memory,etc.). We have a
  chasis serveriron here (350), and we wan't to ease the load for those lower
  machines that are under heavy loads. Our current predictor is set to
  "least local sessions" and the "Leas Session" guy looks
  good but unfortunately its available for stackable device only. 
    
  Appreciate your
  help on this guys. 
    
    
  Thanks and
  regards, 
  Reynald
