There is an architectural constraint with Dell DUP HDD firmware update utility, related to system memory utilization, which is typically encountered on systems with minimal system memory, memory-intensive configurations, multiple RAID controllers, or memory-intensive applications. This issue is typically reported as - The operation was not successful because the device buffer write has failed. And will result in an aborted attempt to update firmware on the identified HDD.
