Hi Natasha, 

If you want to set up the demo in the Amazon cloud, you can grab an image for 
it as described at the bottom of this page . That demo runs on a "small" Amazon 
server with these characteristics: 


1.7 GB memory 
1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit) 
160 GB instance storage 
I/O Performance: Moderate 


I would not go below 1 GB of memory; the Amazon "micro" server has 613 MB of 
RAM and it is not able to run the various services needed (OpenSRF, Postgresql, 
Apache). 


The best supported Linux versions are Debian Squeeze and Ubuntu Lucid. For 
starting up and learning Evergreen, I think running all the components on one 
server will probably be better than trying to set up separate bricks.

Subject: [OPEN-ILS-GENERAL] Server Requirements for Demo 




Hi everyone. I'm helping a four library consortium set up a demo site for 
Evergreen. What I'm trying to find out is what the requirements are for the 
server? 



All I could find was this, which is extremely vague: 

Evergreen Server System Requirements 

There is a lot of variance here, depending on expected load/use, the size of 
your data, the performance you require, and the amount of 
redundancy/availability/failover you want. The entire Evergreen server can run 
in a 1GB virtual image. It can also be spread out across multiple servers, with 
different requirements for different components. It requires some flavor of 
Linnus, though may possibly run on other POSIX systems. 

Supported Linux Distributions 

Database Requirements 

Typical "Brick" for an Evergreen Cluster 

Apache 

Ejabberd 

Evergreen/OpenSRF Services 



Thanks!
