Determine Physical Memory Size in each RAD in ES80

If I have 4 cpus in an ES80, how can I determine whether my 16GB of physical memory is divided as:

8+2+2+4 vs. 4+4+4+4 ?
etc.

Is there a hwmgr command that will tell me the physical memory that I have in each RAD?

This box has been upgraded in the past and I am not sure if it was done optimally or on-the-cheap/forward-looking.

You can use collect -sm to view the memory in each rad. You can the sum values.

You can also use vmstat -r.

Re: Determine Physical Memory Size in each RAD in ES80

What do I sum to determine physical memory in each RAD? Is there a way to determine whether a given RAD is composed of 2x2GB or 1x4GB+1-empty-slot?

A hwmgr option perhaps?

Re: Determine Physical Memory Size in each RAD in ES80

I don't believe that hwmgr has a nice option for this and I don't quite see how "vmstat -r" should help. But if you try "vmstat -P" and look for the "Physical Memory Clusters", then I think it should become obvious. Every CPU has some memory for "pal", so that's where the RAD boundaries are (assuming you haven't played with cpus_in_rad).

The sum of Free + Act + wire will give you close to the ammount of memory on each RAD.

Ah, see what you mean Ivan. However that doesn't always sum up the total for a RAD (think of granularity hints memory for instance). But most of the time that should work.

Agree, the other way will be using the SRM show mem command.

>>> show mem

But you need to shutdown the system. The good news is that the command will give you the exact information you need.
