dimensioning memory

Hi there

 

 

I have to migrate two LTM installations from two ltm clusters into one ltm cluster. As far as I can see it is not clear to check how much memory is used really.

 

 

 

On one LTM I have two http profiles allocated to different virtual servers:

 

 

 

1. 512mb ramcache size (activated on 22 virtual servers)

 

2. 256mb ramcache size (activated on 5 virtual servers)

 

 

 

 

 

b memory show

 

MEMORY STATISTICS --

 

| (Host) Total = 7.817GB Used = 7.764GB

 

| (TMM) Total = 6.200GB Used = 5.290GB

 

 

 

 

b http show

 

GLOBAL HTTP STATISTICS

 

| RAM cache (entries, size, evict) = (545935, 2.415G, 890.4M)

 

 

 

 

 

How do I count this all together to get an overview how much memory I use for a specific virtual server and how I can count this together to check if the sum maches total usage. I need this because I want to be sure that all the ramcache allocation does fit the new setup.

 

 

 

We use LTM 6900 (v10.2.1) .

 

 

 

 

 

Any help is kindly appreciated
