8.1.7 Improved High Availability After Flash Failures

Overall system performance after flash failures has been improved. Previously, after a flash failure, Oracle ASM would start reading from the disks on the affected Oracle Exadata Storage Server as soon as flash resilvering completes. However, the storage server would still have a fewer than normal number of flash devices, so performance on that storage server was affected. Starting with Oracle Exadata System Software 18c (18.1.0), Oracle ASM starts reading from the disks only after all failed flash devices are replaced on that storage server.

Minimum software required:

  • Oracle Exadata System Software 18c (18.1.0)
