In the past, Oracle DBAs seeking maximum performance sought to place critical files, usually the redo logs, on the outer rim of physical disks to achieve maximum performance.
The introduction of Zone Bit Recorded (ZBR) disks meant that there was a greater volume of data on the outer edges of the physical spinning disk, and with the higher relative speed of the head passing over the disk, the transfer rate was up to 50 percent higher on the outer edge.
Since version 220.127.116.11, ASM offers Intelligent Data Placement or IDP that seeks to place files on the fastest outer parts of disks.
However for ScaleIO, such complexities are not relevant and will yield little to no performance improvement. The underlying geometry of any spinning disks is hidden from the SDC host.
DELL EMC recommends relying on the built in optimization technology of ScaleIO to handle data placement within physical disks.
