DO NOT put Informix data on Raid 5
DO NOT

Engine? O/S? Processors? Memory? Data Set Size? No of Concurrent Users? OLTP or Warehouse?
User Performance Expectation?
All these questions and a few others need to be answered before any reasonable intelligent
response.

Subject: Informix and RAID




Hi,
I am an administrator of IDS.
Up till now we have stored data in different chunks distributed betwen different disks to obtain a better performance in read-write operations.
We had the chunks distributed and mirrored in different disks.
We are going to change the hosts and in the new one we are going to have a storage system with RAID5.
Is it reasonable to build different chunks to store critical, non-critical, temporary, etc...... data?
From the viewpoint to improve the performance don't think so, we could store all data in one only big chunk, but could we have other reasons to build different chunks to store data?
Kinds regards,
