Western Digital: Eliminating drive corruption from power disturbances
- Middle East: Thursday, August 20 - 2009 at 15:19
Many Enterprise System OEMs face operational failures because of less-than-optimal power conditions. Approximately 75% of all field failures are due to power disruptions. Spikes, brownouts, surges, blackouts, and other power problems can cause data loss and/or corruption in applications.
PowerArmor's voltage detection circuitry alerts the host system of any power fluctuations and prevents the transmission of commands until power levels are normalised.
Address lines are latched to prevent data from being written to the wrong sector.
When power goes out, drives can be corrupted and data ruined, resulting in downtime as drives get reformatted, operating systems reinstalled, or products returned. This directly impacts overall reliability, dependability, customer goodwill, and cost of ownership.
PowerArmor now offers designers a way to virtually eliminate these costly problems.
