Abstract: Systems and methods for data protection. In some embodiments, a computational storage device includes a controller circuit, a first compute function of a first application, a second compute function of the first application, a common memory area; and a persistent storage device. The controller circuit may be configured: to receive a first request from a host, the first request defining a first allocated function data memory region, for the first compute function; to receive a first memory access request, from the first compute function, for a first memory location in the common memory area and outside the first allocated function data memory region; and to deny the first memory access request.

Abstract: A high endurance persistent storage device. In some embodiments, the persistent storage device includes: a controller circuit; persistent storage media, connected to the controller circuit; nonvolatile memory, connected to the controller circuit; and volatile memory, connected to the controller circuit.

Abstract: Systems and methods for executing compute functions are disclosed. A processing circuit may be configured to: receive a first task from a first application, wherein the first task identifies a first compute function and a second compute function; determine a first order of execution of the first compute function and the second compute function based on first information in the first task; and execute the first compute function and the second compute function according to the first order.

Abstract: Provided is a method of data storage, the method including receiving, at a host of a key-value store, a request to access a data node stored on a storage device of the key-value store, locating an address corresponding to the data node in a host cache on the host, and determining that the data node is in a kernel cache on the storage device.

Abstract: Provided is a data storage system including a host including a host cache portion of a mirror cache, the host cache portion for storing metadata indicating a location of a data node that is stored in a kernel cache portion of the mirror cache, and a storage device including the kernel cache portion located in a common memory area.
