We are currently installing a new 4-way K570 (HP) and will be moving our database to it. My question is about mirroring: I have 5 Fast/Wide SCSI channels, 1 w/ 16GB (4 drives) and 4 w/ 32GB (8 drives). Our database currently takes about 14 GB. With the OS (HP-UX 10.20 using NFS), what is the recommended way to first separate the database and OS (minimum of 9 dbspaces, 3 of which are hugely used) over the chanels? Also, and more importantly: is it better to use the OS's disk mirroring or Informix's own?
