Systems and methods include an Information Handling System (IHS) that is adapted to provide diagnostic boot cycles. Once an IHS is powered, a boot sequence is initiated. During or after booting of the IHS, a request is detected for a diagnostic boot cycle by a requestor, such as by the operating system of the IHS. When a diagnostic boot cycle has been requested, an EC (Embedded Controller) of the IHS is booted in a diagnostic mode to perform a diagnostic test on one or more hardware components of the IHS. The results of the diagnostic test are stored to the NVRAM (Non-Volatile Random-Access Memory) that stores the boot code and that is accessible to the requestor of the diagnostic test once the IHS has been rebooted to a non-diagnostic mode.

A system and method(s) to perform operations for storing gaming data in a non-volatile random-access memory (NVRAM) of a gaming machine and detecting, after the storing, an unrecoverable fault of the gaming machine. The operations further include determining, in response to detecting the unrecoverable fault, that criteria is satisfied for authorization of a partial deletion of the gaming data from the NVRAM. The operations further include determining, in response to determining that the criteria is satisfied, a first portion of the gaming data to retain on the NVRAM, and deleting, after determining the first portion of the gaming data to retain, a second portion of the gaming data without deleting the first portion of the gaming data. The operations can further include booting a game of the gaming machine to a default operational state using at least some of the first portion of the gaming data.

A storage system has NVRAM (nonvolatile random-access memory), storage memory that includes SLC (single level cell) flash memory and QLC (quad level cell) flash memory, and a processor. The processor performs a method that includes selecting one of a plurality of write paths for incoming data, and writing the incoming data via the selected write path. A first write path includes writing to NVRAM, writing from NVRAM to SLC flash memory and writing from SLC flash memory to QLC flash memory. A second write path includes writing to NVRAM and writing from NVRAM to QLC flash memory, bypassing SLC flash memory. A third write path includes writing to SLC flash memory, bypassing NVRAM, and writing from SLC flash memory to QLC flash memory.

A processor that executes an inline deduplication pipeline identifies any data segment which is created from data received with a write request from a client, and which is unique relative to data segments stored by the inline deduplication pipeline. The processor logs any segment reference of any data segment which is identified as unique, and any data received from the client and yet to be anchored into any data segment, into persistent memory, which has a lower write latency than any non-volatile random-access memory device that is external to the persistent memory. A hardware accelerator, which has a lower compression latency than the processor, compresses any data segment identified as unique, and stores any compressed data segments into the persistent memory. The client is enabled to provide additional data by the processor acknowledging to the client that the data received from the client is stable in the persistent memory.

An indication that power loss protection (PLP) for a non-volatile random access memory (NVRAM) portion of a storage device has failed is received from the storage device. The storage device is marked to indicate the storage device has a PLP failure. A write path to store data at the storage device is modified to avoid storing the data in the NVRAM portion of the storage device that has the PLP failure.

Systems and methods include an Information Handling System (IHS) that is adapted to collect boot telemetry in a secure manner. Boot code of the IHS is executed to initiate a boot sequence that includes the generation of boot telemetry. The boot telemetry is collected in a partition of an NVRAM (Non-Volatile Random-Access Memory) of the IHS. When the capacity of the partition of the NVRAM reaches a threshold, the boot telemetry is transmitted from the NVRAM to a security device of an SoC (System-on-Chip) of the IHS for encryption of the boot telemetry. The encrypted boot telemetry is stored in an SSD (Solid-State Drive) of the IHS.

Systems and methods for performing journal swapping are provided. In one example, the backing storage used for virtual non-volatile random access memory (vNVRAM) is dynamically switched based on the high-availability (HA) state of an HA pair of nodes of a virtual storage system. By default, in-memory logging may be used for write journaling when the HA pair is operating in a normal HA state. When the HA pair is in an HA degraded state, the write journaling may be performed to local ephemeral storage. This allows the file system of the virtual storage system to run in a more performant configuration most of the time (e.g., during which HA is enabled and healthy). At the same time, the file system has the ability to swap to a less performant but more resilient configuration during planned events (e.g., scheduled maintenance and throughput scaling) in which HA is in a degraded state.

According to a method, a computer-implemented method includes: calibrating a given page in a block using a first calibration scheme (606) by calculating a first number of independent read voltage offset values ​​for the given page. An attempt is made to read the calibrated given page (608), and in response to determining that an error correction code failure occurred during the attempt to read the calibrated given page, the given page in the block is recalibrated using a second calibration scheme (612). The second calibration scheme is configured to calculate a second number of independent read voltage offset values ​​for the given page. An attempt is also made to read the recalibrated given page (614). In response to determining that an error correction code failure did indeed occur during the attempt to read the recalibrated given page, one or more instructions (618) are sent for relocating data stored in the given page.
