I've finally, after some pain and frustration, have gotten our z990 and DS8300 communicating via the SAN. I'm defining the devices on the z/VM 5.4 side using edev. So far, this has just been a test to figure out how to make it work. However, I'm planning on making use of this on a z9 for our production Linux guests who need access to large data volumes (i.e. our Oracle servers, etc.).
I know very little about the performance issues of edev vs. direct SCSI connections, NPIV and all of that stuff. I've read some of the presentations and red books and, well, after some bouts of dizziness, I realize that I don't get it. So, can anyone who is doing this in "real life" like to share some pearls of wisdom? What are the practical limits to the number of edevs you should create on a single FCP connection? Are there limits to how big a LUN you should have connected, or does it matter?
