Dot Hill Systems Corp., the Longmont, Colorado-based SAN storage provider, has patented a method to safeguard data and preserve cache in the event of main power loss.
Cached write data and metadata stored in volatile memory must be preserved in the event of a power loss. When power loss occurs, valuable data is transferred from volatile memory to the non-volatile memory of the computer's memory system. This transfer of data is known as memory flush operation.
Dot Hill's patent also provides a method to reduce power usage in computer memory systems during volatile memory flush operations. This innovation reduces power required for a memory flush operation by selectively providing power to certain computer components at certain times, and not to others. By reducing this power requirement, a smaller power source, such as a supercapacitor, can be used by the computer memory system.
The patent is included in the Dot Hill AssuredSAN and AssuredSAN Pro storage arrays, which are equipped with a number of energy-saving features, including dot Hill's patented EcoStor ™ "green" battery-free alternative for cache memory, drive spin-down and data center power options.
