Infor OS Sizing Guide

Ryan Pukanski

Hi everyone,

We currently use Infor OS on premise for ION and we are looking to transition users to accessing Syteline through Mingle so we can use the homepages functionality. One thing I cannot find is a sizing guide. I am not sure how many servers we should provision per user. Does anyone have any insight on best practice? Right now we have about 80 users and one Infor OS Server.

Thanks
Ryan

Ryan - The answer will depend on the version of InforOS that you are running. Somewhere along the way, InforOS switched to Elastic Search for its indexing tool for search capabilities (12.0.30 or .32 I believe).

Pre-Elastic, the recommendation is to have 2 InforOS servers, so that you have the N+1 setup and have an additional server to take over the load, should one fail. This is standard best practices on all hardware and servers.

Post-Elastic, the recommendation is to have 3 InforOS servers, due to the Elastic requirements of N/2+1, the recommendation is to have 3 InforOS servers. Elastic shares its indices, if you were to lose 1 of 2 servers, you would only have access to half the indices. Having 3 servers always give you a "hot spare", preventing split-brain issues.

This requires a Load Balancer and shared network drive that all 3 servers can communicate with and store shared information.

A side note for more than one server, is that the first server installed is the Master and has the master roles. Should something happen to this server, where it is not recoverable, you would need to move the master roles and promote another server, using the Redis tools.

You can, technically, run 80 users on 1 InforOS server. I would recommend using 48gb of memory, and potentially 6/8CPU, if possible. However, this does not comply with the industry standard of N+1.
