[OPEN-ILS-DEV] Server hardware requirements

[Kivilahti Olli-Antti]

Hello community!

I should start making initial specifications about the server hardware 
we are about to use. I would love to hear what kind of hardware setups 
you have running your Evergreen installations and under what transaction 
loads.

Also one interest is about the ratio of write to read queries, as it 
effects the way centralized data storage is arranged, if it is arranged. 
Currently we are unable to gather such data from our old system.

I think we can infer some statistics about our own OPAC and staff client 
usage statistics to make some kind of a educated guess, but that would 
rely heavily on the usage data community would kindly provide us as the 
baseline comparison.

Also it looks like we will be using pgpool-II to load balance our DB 
cluster, and mirror our EG DB to our mobile libraries. I am hatching a 
cool idea about using torrents to move WAL-chunks between mobile 
libraries, of which we have 4. Maybe it is pointless, but we still have 
area's without a wireless internet coverage, so having a searchable EG 
DB is a bonus in addition to the offline mode.
