Version: 3.1-23033

(2021-06-01)

Important Note

  1. The update is expected to be available for all regions within the next few days, although the time of release in each region may vary slightly.

  4. Reduced the impact on I/O performance during Space Reclamation.
  5. Greatly reduced the time needed to initialize Thick Provisioned LUNs after creation.
  6. The new LED indicator behavior makes the system status easier to distinguish.
