Multicast install of nodes
Hi
Does ICE-Linux do multicast install of nodes ?
If not what is the practical limit to the number of concurrent installs that can happen ?

Re: Multicast install of nodes
Hello Alex. No, ICE-Linux does not do multicast installs.
The default maximum number of concurrent O.S. installs is 16 and the default number of concurrent image deployments is 10. This can be increased by editing your "/opt/mx/icle/icle.properties" file and adding "MAX_CONCUR_CHAINS=". Currently, the default value for MAX_CONCUR_CHAINS is 64. Each O.S. install carries a weight of 4 and each image deployment carries a weight of 6. Therefore, the maximum O.S. installs is calculated by:
64/4=16
The maximum image deployments is calculated by:
64/6=10
The number of concurrent installs that your CMS can handle would be dependent on your processors, memory, and network bandwidth.
If you do change MAX_CONCUR_CHAINS, you'll need to restart ICE-Linux for the change to take effect.
Are you doing an O.S. installation or a deployment of a captured image? How many nodes are you installing?

Re: Multicast install of nodes
Hi
Just sizing up the product.
is this a limit imposed by the services that the ice-linux box provides ?
ie if I was doing a scripted install and the images boot + ks and/or RHEL repo where on another server would that alleviate the problem a bit ?

Re: Multicast install of nodes
That limit assumes one 2-GHz CPU and 1-Gig of RAM on your CMS. You can increase the limit if your CMS has more than that.
Putting the OS files on a remote repository doesn't change the number of concurrent tasks that can be run, it will only offload the work of transferring the O.S. files from the CMS's web server to the remote web server. To increase the number of concurrent tasks you need to increase MAX_CONCUR_CHAINS.
