Hi there, Was at the Lenovo GNR/GPFS 5.x seminar the other week and we briefly discussed whether or not the recommendation was to place data in the system pool (eg. have one combined system/data pool), or to have them separate. We’ve got a GSS26 that we are creating new filesystems on for high speed scratch (16 MB blocks).
I unfortunately did not note all of the considerations/caveats related to this choice. Does anyone who knows/was there and can remember remind me? The recollection I have is that you may have some contention for I/O if your metadata is on your data disks, and you won’t be able to have different redundancy settings. Once upon a time, block size also mattered, but not so much on 5.x.
