Systems and methods for storage pruning can enable users to delete, edit, or copy backed up data that matches a pattern. Storage pruning can enable fine-grain deletion or copying of these files from backups stored in secondary storage devices. Systems and methods can also enable editing of metadata associated with backups so that when the backups are restored or browsed, the logical edits to the metadata can then be performed physically on the data to create a custom restore or a custom view. A user may perform operations such as renaming, deleting, modifying flags, and modifying retention policies on backed up items. Although the underlying data in the backup may not change, the view of the backup data when the user browses the backup data can appear to include the user's changes. A restore of the data can cause those changes to be performed on the backup data.

A solid state drive (SSD) employing a redundant array of independent disks (RAID) scheme includes a flash memory chip, erasable blocks in the flash memory chip, and a flash controller. The erasable blocks are configured to store flash memory pages. The flash controller is operably coupled to the flash memory chip. The flash controller is also configured to organize certain of the flash memory pages into a RAID line group and to write RAID line group membership information to each of the flash memory pages in the RAID line group.

Technologies for switching network traffic include a network switch. The network switch includes one or more processors and communication circuitry coupled to the one or more processors. The communication circuitry is capable of switching network traffic of multiple link layer protocols. Additionally, the network switch includes one or more memory devices storing instructions that, when executed, cause the network switch to receive, with the communication circuitry through an optical connection, network traffic to be forwarded, and determine a link layer protocol of the received network traffic. The instructions additionally cause the network switch to forward the network traffic as a function of the determined link layer protocol. Other embodiments are also described and claimed.

A storage system includes a host including a processor and a memory unit, and a storage device including a controller and a non-volatile memory unit. The processor is configured to output a write command, write data, and size information of the write data, to the storage device, the write command that is output not including a write address. The controller is configured to determine a physical write location of the non-volatile memory unit in which the write data are to be written, based on the write command and the size information, write the write data in the physical write location of the non-volatile memory unit, and output the physical write location to the host. The processor is further configured to generate, in the memory unit, mapping information between an identifier of the write data and the physical write location.

Systems and methods for generating and using a placement map for a distributed storage system are disclosed. In some embodiments, a method for a client node to perform a read/write operation in a distributed storage system comprises obtaining a number of server nodes comprised in the distributed storage system and an object name of an object for which a read/write operation is to be performed and creating at least a portion of a three-dimensional (3D) placement map for the object. The 3D placement map defines candidate locations for replicas of the object on the server nodes. The method further comprises applying policies to the at least a portion of the 3D placement map to provide at least a portion of a modified 3D placement map and performing the read/write operation for the object in accordance with the at least a portion of the modified 3D placement map.

A communication device provides data to a data acquiring node based on a consensus of a plurality of participating nodes. The communication device includes a processor. The processor divides the data into N data components. N is an integer equal to or larger than two. When the N data components are stored in different storage areas, the processor encrypts addresses of storage areas in which the data components are respectively stored with respective public keys of N participating nodes among the plurality of participating nodes. The processor transmits access right information that indicates the data acquiring node has a right to access the data and the encrypted N addresses to the plurality of participating nodes.

Techniques for adaptive re-keying of encrypted data are provided. For example, a method comprises the following steps. Utilization information associated with a storage system is obtained, wherein the storage system comprises a set of storage devices. The method dynamically selects a re-keying process from a plurality of different re-keying processes based on at least a portion of the obtained utilization information. At least a portion of the set of storage devices are re-keyed in accordance with the selected re-keying process.

An electronic device according to various embodiments of the present invention comprises a host device and a block device electrically connected to the host device, wherein the block device comprises a first memory and a controller electrically connected to the first memory, and the controller receives a write request for first data form the host device, determines whether the first data is pattern data configured in a form in which an assigned number of bit values are repeated, and, in response to the first data being determined to be the pattern data, controls the first memory to store the assigned number of bit values of the first data in a logical to physical mapping table after mapping the assigned number of bit values to a logical address indicated by the write request.
