Hello, In an environment with an LSI 3108 based HW-RAID60, 256k stripe size on controller, 5 spans of (10data+2parity) disks. What is the proper su & sw to use? Do I do sw to the underlying 10 data disks per span? The top level 5 spans or all 50 data disks with the array? Use case is as a file server for 20-60 MB per frame image sequences. i.e 1) sw=256k,sw=10 2) sw=256k,sw=5 3) sw=256k,sw=50 RHEL 8.1 Thank you, Alan
