How to calculate how long drive firmware upgrade will take on E-Series?

Last Updated:

Applies to

E-Series Arrays


  • This depends on if the firmware is upgraded Offline (Parallel) or Online.
  • Timing of the drive firmware download operation:
    • The parallel drive firmware download operation can take as long as 90 seconds to complete if all drives are updated on a 24-drive system. On a larger system, the execution time is slightly longer.
    •  The online drive firmware download operation will take approximately two minutes per drive to complete. Actual time depends on several factors, including the following:
      •  I/O load on the storage array and the amount of I/O activity occurring during an online firmware download operation (write-heavy workloads will cause the online firmware download time to increase)
      • Number of drives that are participating in the download
      • Drive performance
      • Number of volumes and size of volumes that reside on the drives that are participating in the download
      • RAID level of the associated disk pool or volume group

Note: SSD Cache drives must be offline and suspended to complete the upgrade.
