[Gluster-devel] Feature Idea.

[Nick Clarke]

Hi,


 


I stumbled across Gluster while looking for a Linux cluster
system and instantly had a big smile on my face after a couple of clicks.  This 
is a great project and not a small one.


 


I did have an idea for a feature, not sure if it would something
for Gluster or the scheduler.


 


Power Save


The ability to Suspend /Sleep/Shutdown nodes (or groups of
nodes) when they are not needed.


 


Node states:


            - Suspend:
Do not start up until a set time for example.


            - Sleep:
Faster start up


            - Shutdown:
Longer to start up but no power consumption


 


Node type examples:


            Data Centre


                        Achieve


                        Live


                        ….


            HPC


                        Render
Farm


                        Web
Server


                        ….


            Etc..


 


-Timed Suspend/Sleep/Shutdown


                        7pm – 9am for example


 


- Rule based power saver based on node type e.g. Data Centre,
HPC node etc..


An example: A group of data centre nodes could be used for achieve
and rarely used, so they could be set to Suspend after 2 hours of no use and
only started when something is required. As their function is storing achieved
data the user would allow for a small start up delay.


 


- Suspend/Sleep/Shutdown when not needed.  PXE boot when needed (incoming large 
jobs, or
during a time window).


 


This would allow me and I’m sure others to save a lot of running
costs.
