Benefits of technology

The present invention relates to an improved method for managing errors in a computer system's memory. It achieves this by utilizing multiple different types of memories called RAID or RAID6, which are specialized hardware components used to improve performance. These memories have unique characteristics that make them suitable for use in error correction systems. When there is some problem with certain parts of these memories, they can help restore their original functioning without losing important data. Overall, this technology improves efficiency and reliability in computing operations.

Problems solved by technology

This patent describes various technical problem addressed in this patent: The patent discusses different ways to improve the efficiency of data management systems. Specifically, there is a trade-off between the allocation of spare memory and the performance of the original data. By dividing the spare memory into multiple parts, the system becomes more reliable and able to handle failures effectively. However, the solution proposed should avoid increasing the size of the spare disk needed for the entire system.

Embodiment Construction

[0035]In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. Description associated with any one of the figures may be applied to a different figure containing like or similar components / steps. While the flow diagrams each present a series of steps in a certain order, the order of the steps may be changed.

[0036]FIG. 3 depicts system 10 in which storage system 12 may be communicatively coupled to host 22. Host 22 may transmit read and / or write requests to storage system 12, which in turn may process the read and / or write requests. While not depicted, storage system 12 may be communicatively coupled to host 22 via a network. The network may incl

Abstract

Described herein are techniques for storing data in a redundant manner on a plurality of storage units of a storage system. While all of the storage units are operating without failure, only error-correction blocks are stored on a first one of the storage units, while a combination of data blocks and error-correction blocks are stored on a second one of the storage units. Upon failure of the second storage unit, one or more data blocks and one or more error-correction blocks formerly stored on the second storage unit are reconstructed, and the one or more reconstructed data blocks and the one or more reconstructed error-correction blocks are stored on the first storage unit.
