A specific implementation scheme includes: storing at least one target data into a target file in a storage class memory device; recording a storage address of the at least one target data in the storage class memory device in a dynamic random access memory as a first index data; and synchronously storing the first index data into the storage class memory device as a second index data.

Embodiments of the present disclosure relate to a memory system and an operating method of the memory system. According to embodiments of the present disclosure, a memory system may divide and manage the plurality of memory dies into a plurality of memory die groups, may set a first super memory block including at least one of memory blocks included in a first memory die group, and a second super memory block including at least one of memory blocks included in a second memory die group, may determine whether to set an extended super memory block in which all or part of the first super memory block and all or part of the second super memory block are merged, and may write a write data to the extended super memory block in an interleaving manner when writing the write data requested by a host.

A storage controller including: a host interface circuit receiving first, second, third and fourth requests corresponding to first, second, third and fourth logical addresses; a memory interface circuit communicating with first nonvolatile memories through a first channel and second nonvolatile memories through a second channel; a first flash translation layer configured to manage the first nonvolatile memories; and a second flash translation layer configured to manage the second nonvolatile memories, the first flash translation layer outputs commands corresponding to the first and fourth requests through the first channel, and the second flash translation layer outputs commands respectively corresponding to the second and third requests through the second channel, and a value of the first logical address is smaller than a value of the second logical address, and a value of the third logical address is smaller than a value of the fourth logical address.

Techniques are disclosed for content storage in a way that facilitates consistent and concurrent read/write processing of stored documents. An example methodology implementing the techniques includes segmenting the contents of a document into a plurality of content segments and storing the plurality of content segments within a data structure, the data structure including storage blocks having storage portions and buffer portions. The storage of the plurality of content segments includes storage of content segments within a storage portions of the storage blocks of the data structure. The method also includes receiving at least one change to the content and utilizing a buffer portion of at least one storage block to store the at least one change to the content.

In one aspect, an apparatus includes a memory repair controller coupled to a memory. The memory repair controller may be configured to provide repair information to cause the memory to disable one or more faulty locations in the memory, and the memory repair controller can be disabled after providing the repair information.

A solid state drive (SSD) includes a first storage region classified as byte addressable NV storage region and a controller communicatively coupled to the first storage region by a bus. The controller detects a reduced storage capacity of the first storage region, and in response to the detection, reclassifies the first storage region as a block addressable NV storage region. The SSD dynamically changes byte addressable NV storage regions to block addressable NV storage regions as the byte addressable NV storage regions are degraded, thereby extending the longevity of the SSD.

Features are disclosed for forecasting a usage of a block storage volume with a first configuration by a user. A computing device can forecast the usage of the block storage volume based on the historical usage of the block storage volume by the user. The computing device can determine additional potential configurations of the block storage volume. The computing device can further simulate the additional potential configurations of the block storage volume based on the forecasted usage of the block storage volume. The additional potential configurations may include a volume type, a volume size, or other volume characteristics. Based on the simulations of the additional potential configurations, the computing device may determine a recommended configuration. The computing device can dynamically modify the block storage volume based on the recommended configuration of the block storage volume.

A transfer method is performed by an information processing apparatus. The method includes: selecting, based on a load status of the information processing apparatus, candidate transfer data that is among the received data and to be transferred to one or more other information processing apparatuses; selecting, based on load statuses of multiple other information processing apparatuses, one or more candidate transfer destination apparatuses among the multiple other information processing apparatuses as candidate transfer destinations of the data; determining, based on throughput between the information processing apparatus and the candidate transfer destination apparatuses, data to be transferred among the candidate transfer data, transfer destination apparatuses of the data to be transferred among the candidate transfer destination apparatuses, and the sizes of data groups including the data to be transferred; and transferring, to the transfer destination apparatuses determined for the determined data groups, the determined data to be transferred.

A method and system for auto live-mounting database golden copies. Specifically, the disclosed method and system entail reactively auto live-mounting golden copy databases on hosts or proxy hosts based on the operational state of one or more database hosts and/or one or more assets (or databases) residing on the database host(s). Should a database host prove to be unresponsive, through periodic monitoring, databases residing on the database host may be brought back online on a proxy database host using stored golden copies respective of the aforementioned databases. Alternatively, should a given database on any database host exhibit an operational abnormality (e.g., an error, failure, etc.), the given database may be brought back online on the database host or a proxy database host using a stored golden copy respective of the given database. Accordingly, through the disclosed method and system, database outages may be minimized.

A memory system includes a memory device, a memory controller configured to control the memory device, and an interface device configured to perform an interfacing operation for transmission of a control signal and data between the memory device and the memory controller. The interface device activates a blocking function for the interfacing operation in response to a configuration command of the memory controller including a blocking activation signal and performs an interface configuration operation in response to an interface configuration command of the memory controller while the blocking function is activated.
