Abstract: A method for managing security keys for an I/O device may include loading a first security key from a primary memory to a security engine, performing a first data transfer operation between a host and the I/O device using the first security key with the security engine, loading a second security key from a secondary memory to the security engine, and performing a second data transfer operation between the host and the I/O device using the second security key with the security engine. The method may further include storing the first security key in the primary memory based on a frequency of use of the first security key. The frequency of use of the first security key may be determined by a pattern of transfers between the host and the I/O device.

Abstract: Methods and devices are provided in which a controller of a storage device generates copy-read subcommands and copy-write subcommands of a copy command. The controller executes a blocking no-operation (NOP) command that spans a first storage address range of the copy-write subcommands in a first storage address space. The controller generates a mapping of the copy-write subcommands from the first storage address range, to mapped copy-write subcommands at a corresponding second storage address range in a second storage address space that is higher than a maximum storage address of the first storage address space. The controller executes the copy-read subcommands and the mapped copy-write subcommands. The mapped copy-write subcommands copy data for execution at the first storage address range.

Abstract: An appliance is described. A write engine may process a write request from an application to write a first data into a memory. The write request may including the first data and an address. A compression engine may compress the first data to produce a first compressed data. A write module may store the first compressed data in the memory. The first data may be a first part of a page that may further include a second data as a second part. The first compressed data may be a first part of a compressed page that may further include a second compressed data as a second part.
