Pool Statistics

Hi,

 

In a Viprion system I've configured a VS with two nodes in a pool.

 

After, I've set the connection limit to each node to 1500 but in the pool statistics menù, the maximum connection for each node stop to 750.

 

Why?

 

 

Thanks in advance

have you seen this one?

 

 

sol8457: Connection limits configured on pool members or nodes within a Clustered Multi-Processing configuration are incorrectly enforced per TMM instance

hope this helps.

Yes but I 've Release 11.1.0, not 9.6.x

Yes but I 've Release 11.1.0, not 9.6.xthe solution is applied to up to 11.2.1. the 9.6.0 and 9.6.1 issue is each blade (instead of each tmm) incorrectly performs connection limit.

So, It's a bug....right?

On VIPRION the connection limit should apply per blade. Are these nodes in any other Pools? Perhaps you could change the connection limit to 3000 and apply it to the Pool rather than the Nodes.

I've just one blade. Each node is in three different pools and I must use connection limit on the node...

Nitass, What Lies Beneath,

 

thanks for your quick answers but I need to summarize...

 

It's a single blade and the pool statistics menù show 750 connections per node instead of 1500 per node.

 

 

Can I say..."You need to update the Viprion to solve this issue" ?

Iirc that bug hasn't been fixed yet has it?

 

 

 

From memory, the way its doing things is dividing the number of connections max by the number of tmm's on the blade... So you get 750 per tmm...

sorry i think i was wrong. sol8457 should not be the case. i was able to get a number of connection limit i set.

If I remember well, Viprion 2100 blade include:

 

8 TMM istances and 1 TMM process per hyperthreaded core.

 

 

So, what is the correct computation?
