Hold-Up Capacitor Failure Handling in Data Storage Devices - A simplified explanation of the abstract
This abstract first appeared for US patent application 18348316 titled 'Hold-Up Capacitor Failure Handling in Data Storage Devices
Simplified Explanation
The data storage device described in the patent application includes hold-up capacitors, a controller, and a write cache. The controller is able to detect failed hold-up capacitors and reallocate write buffers in the write cache for subsequent write operations based on the count of failed capacitors.
- Hold-up capacitors provide back-up power for non-volatile memory
- Controller detects failed hold-up capacitors and reallocates write buffers in response
- Reallocation of write buffers improves efficiency of subsequent write operations
Potential Applications
The technology described in this patent application could be applied in various data storage devices such as solid-state drives, servers, and network-attached storage systems.
Problems Solved
This technology helps to address the issue of failed hold-up capacitors in data storage devices, ensuring that data is not lost during power outages or other disruptions.
Benefits
- Improved reliability of data storage devices - Enhanced data protection during power failures - Increased efficiency in write operations
Potential Commercial Applications
"Enhancing Data Storage Device Efficiency through Hold-Up Capacitor Reallocation"
Possible Prior Art
There may be prior art related to data storage devices with hold-up capacitors for power backup, but the specific technique of reallocating write buffers based on the count of failed capacitors may be a novel innovation.
Unanswered Questions
How does the controller determine the count of failed hold-up capacitors?
The patent application does not provide details on the specific method used by the controller to determine the count of failed hold-up capacitors.
What impact does reallocation of write buffers have on overall system performance?
The patent application does not discuss the potential effects of reallocating write buffers on the performance of the data storage device.
Original Abstract Submitted
A data storage device includes a plurality of hold-up capacitors configured to provide back-up power for a non-volatile memory, a controller, and a write cache. The controller is configured to detect one or more failed hold-up capacitors of the plurality of hold-up capacitors; and in response to detecting the one or more failed hold-up capacitors: perform one or more quiesce operations and determine a count of the one or more failed hold-up capacitors. Based on the count of the one or more failed hold-up capacitors, the controller is configured to reallocate the write buffers of the write cache for use in one or more subsequent write operations.
