Problems solved by technology

While these may offer significant cost savings relative to the capacity required to meet the storage needs of a given server or application, the performance penalty of performing write IO against these storage means that they cannot be used for general purpose IO
Their algorithms increase the cost of performing IO and limit the peak throughput they can support

Embodiment Construction

[0022]FIG. 1 shows a data storage system 1 , which includes a controller 10 , a first low-performance storage medium 12 , and a second high-performance storage medium 14 . The controller 10 is connected to the storage media 12 and 14 and is arranged to control IO access to the storage media 12 and 14 . Although the two storage media 12 and 14 are shown as being the same size, they may differ in physical size and / or data storage capacity. For example, the low-performance storage medium 12 may be a hard disk, and the high-performance storage medium 14 may be a solid-state storage device. The controller 10 manages IO access to the data storage, whether read or write access.

[0023] The controller 10 is configured to store an image on the first storage medium 12 . The image will be data representing multiple applications and servers. The controller 10 is also configured to initiate a copy function from the first storage medium 12 to the second storage medium 14 . The copy fun...

Abstract

A data storage system comprises a controller, a first lower performance storage medium and a second higher performance storage medium. The controller is connected to the storage mediums and is arranged to control IO access to the storage mediums. In operation, the controller is arranged to store an image on the first storage medium, initiate a copy function from the first storage medium to the second storage medium, direct all IO access for the image to the second storage medium, and periodically age data from the second storage medium to the first storage medium.

Description

technical field [0001] The present invention relates to data storage systems, and methods of operating data storage systems. In one embodiment, the FlashCopy process is used to separate frequently accessed data from less frequently accessed data. Background technique [0002] In big data storage systems, many different types of storage media are often used. The various types can be categorized by many metrics such as capacity, availability, performance, and cost. Examples of different attributes that distinguish different types of storage may include attachment technology (e.g., SATA or FC / SCSI) drives, redundancy schemes (e.g., RAID-5, RAID-1, or RAID-10), and space A saving algorithm (eg, compression, de-duplication, or non-compression). A new emerging storage technology is storage-class memory, of which flash memory is a preferred example. Different applications and servers on storage media will have varying requirements regarding these metrics. Each application will...
