Good day to everybody at the devel-list. And greetings from Finland! Hi Finland, here is France ;-)
The library of Joensuu has started a project to compare different open source library systems, mainly Koha and Evergreen, with the goal of moving from our current closed source system to open source. We are planning to create a consortium of minimum of a ~20 libraries, but if open ILS are found to be superrior, probably the consortium can easily grow to ~250 libraries with ~5 million articles and ~150 000 transactions/hour. Our largest customer is a little bit smaller, but not that much : 48
(just FYI : there is a monestary in finland that uses Koha. Ask Monk Viktor (mviktor@valamo.fi) ) libraries, 1.3 millions items (and 760k biblios), something like 1 million check-out per year. The hardware is a bi-quadri-core (8 cores), 12GB RAM, RAID10 hard disks (84GB used for system/koha/zebra, and 26GB used for mySQL) The server is far from being overloaded. There is no specific hard disk, and no NAS or something like that. Just take care of what I wrote on our blog : http://www.biblibre.com/en/blog/entry/mysql-default-config-and-very-large-ko... About the pc units, we haven't changed any computer. So some are very old (5years or more). The only requirement is to be able to run Firefox. So even a winXP should be OK. The server is centralized and host the 48 libraries catalogues, that are considered as one. I don't see how you could have every library hosting their own database if you want to have a true network (ie: with easy transfers/holds/check-in/out) between branches. The OPAC can be integrated with Drupal through SOPAC. We've made the ILS-DI connector for Koha, and the ILS-DI connector for Drupal. However, if you want to investigate deeper, you should drop me a mail, there are some problems we've solved and that are not on official SOPAC (in 2 words : the sopac guys want something working with any ILS and any portal, we think it's better to use all drupal specific features) I'm not sure though that it would work well with a 5 million records database.
