[OPEN-ILS-GENERAL] Server Requirements for Demo

[bfeifarek at q.com]

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.

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!
