Hi Finland, here is France ;-)

(just FYI : there is a monestary in finland that uses Koha. Ask Monk

Our largest customer is a little bit smaller, but not that much : 48
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-koha-database

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.
