Hi,

in principal it is possible to have an archive engine and MySQL database running on the pi. AFAIK not the CSS Archive Engine though.
But I completely agree with Kay: The Pi is good for running IOCs on it, but I would not use it as storage.
We are operating Pis extensively for our control system and already had to exchange several SD cards...

Using a linux PC for storage (and maybe also GUI) is definitively the better solution.

Cheers
Florian

Yes. We intent to make the pi the only  and complete control system. Is it possible to save the PV info in it?

If we cannot manage to do it in the pi. We will then go to the option of using another linux PC to save the data.

Thanks

Hi:

Is your raspberry pi the complete control system, or more like one IOC in the control system?

It’s perfectly fine to run IOCs on the pi, but the pi with its SD card for storage is not ideal as an NFS file server or a relational database server (MySQL).
You can run MySQL on an ordinary Linux computer with real disk, and then also run the archive engine and client GUI on there, getting data from one or more IOCs on one or more pies.

My professor suggested me to use the CSS archive engine from SNS (oak Ridge,TN) available here: https://ics-web.sns.ornl.gov/css/updates/apps/

..

What i want is to store Epics PV's archive in my raspberry pi.  Do you have any better suggestion compatible with CSS "Data-Browser" and MySQL?
