Hi Martin,
We use many virtual servers for that project.
By this day,
There are 3 clusterted MariaDB servers,
Many web servers, OPAC and Intranet servers are clustered and distinguished,
1 zebra server,
1 specific server for user id cards, lists, etc.
1 server for SIP2.
All of them have Intel CPUs, we used a big memory araoun 100GB per each
for databases since we use database very often
in our solutions.
Since they are all virtual servers, increasing or decreasing disk, cpu
and rams are quite easy.
Those are for our big installation of course, in our other customers,
only one server can serve all the requirements.
I hope this information will be satisfactory, if not please do not
hesitate to contact to me.
Thanks

Hi all,
I'm glad to share that we successfully migrated old 2.x Koha to new one,
3.20.
I should also say that this a quite derived version of 3.20, we have
added many new features,
new modules and changed a lot of codes for the use of public libraries
so we may call this Koha
version as Koha -- Devinim.
We've migrated 1.220.000 active users, 13.700.000 items with active 900
libraries of 1126 public libraries all cities of
Turkey.
We use 14 servers for all production and 4 servers for test environment.
We use MariaDB and Galera Cluster with 4 nodes, 8 apache servers and 1
zebra server.
We plan to cluster zebra server in the future, it cannot perform very
well for this kind of huge installation.
During migration, we also cleaned some dirty data, this was also a big
issue for 13m items.
We've done many tests before going live.
OPAC page is http://koha.ekutuphane.gov.tr
Thanks

Hello Mengu,
I am making feasibility study of migrating libraries of Masaryk university
in Czech republic from Aleph to Koha, and I would like to ask you, what
kind of hardware do you use, some parameters would be great to know.
Is it possible for you to provide these details?
Thanks in advance, looking forward for your reply.
