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.
