Hello Martha, You don't seem t have gotten many replies, so let me try.
>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 am not using edev but native FCP/NPIV. I have looked at edev in the start, but decided against them. As in your case I mainly use FCP based storage for large chunks for TSM, SAP etc. I am prepared to hand-fit lun's for those instead of carving from a big pool. >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. I really recommend using NPIV with dedicated lun's. It will save so much headaches later on. I seems more work due to virtual wwpn's being involved and needing to be zoned on the SAN, but the isolation between guest provided easily wins out. >Are there limits to how big a LUN you should have connected, or does it matter? I have lun's up to almost 2 TB and have never seen a problem being attributed to largish lun's. Hope this helps.
