Re: Memory and carrier removal

Carrier? Do you mean the memory board?

The server should be able to boot and using another memory board, of course.

Hope this helps!

Hi,

If you swap the memory board between 2 server than both will surely boot up. But not if you took the memory board.

Re: Memory and carrier removal

As long as you have the minimum amount of memory installed (required by the OS), the system will boot.

Hope this helps!

Re: Memory and carrier removal

My original thought was that the Kernel would freak out due to the loss of memeory.

Also I was not sure if this server could hold more than one memoery board.

one board may to to choose from.

Points for all

Re: Memory and carrier removal

The kernel is happy if he has enough memory. With the current virtualization software you can even increase the amount of memory online.

Just make sure to have a valid memory configuration - see the install/upgrade manual from http://docs.hp.com .

Hope this helps!

Torsten.

Re: Memory and carrier removal

Hi James,

There is a single memory board. It comes in two models of 16 DIMMs or 32 DIMMs. These DIMMs are in pairs from memory. Hence removing them in pairs will be fine until the minimum memory pair.

hi Jim,

The server will definitely boot however I am not sure that your application processes would be able to start properly.

Maybe you will have to do some adjustments.

hope this helps too!
kind regards

Re: Memory and carrier removal

Hi James,

Maybe you can try to monitor the memory usage of the rp4440 server that you are going to remove the memory from for a week or 2. Paging activities can be a good indicator of insufficient memory during such activities. Commands like 'vmstat' and 'swapinfo -mat' are good to be used to monitor the memory usage.
