A storage device includes a flash memory-based cache for a hard disk-based storage device and a controller that is configured to limit the rate of cache updates through a variety of mechanisms, including determinations that the data is not likely to be read back from the storage device within a time period that justifies its storage in the cache, compressing data prior to its storage in the cache, precluding storage of sequentially-accessed data in the cache, and/or throttling storage of data to the cache within predetermined write periods and/or according to user instruction.

Methods and systems for reducing churn in a caching device

A storage management application of a storage array is operable to create a new volume on the storage device array, and to automatically configure, responsive to user selection of an application protection profile, data protection services for application data to be stored on the volume, and/or, responsive to user selection of an application performance profile, application specific performance parameters. The application protection profile specifies scheduling and replication of snapshots for application data to be stored on the volume, and the application performance profile specifies performance parameters such as setting a block size, enabling or modifying a data caching algorithm, turning on or modifying data compression, etc. The scheduling, replication and/or application performance may be managed by a daemon associated with the storage management application which communicates with an agent associated with an application server on which the application executes.

Methods and systems for throttling writes to a caching device in response to read misses

Described herein are techniques for arranging a plurality of M.2 solid state drive (SSD) modules and flash storage elements into a compact form factor. On a first side of an SSD sled, a plurality of M.2 SSD modules may be communicatively coupled to a port expander. On a second side of the SSD sled, a plurality of flash storage elements (not packaged into M.2 SSD modules) may be present. A plurality of SSD sleds (with the above-described characteristics) may be sized so as to collectively fit into a single hard disk drive (HDD) compatible compartment of a chassis.
