An information handling system with improved data security has a signal detector circuit to receive a signal interrupt from a plurality of signal interrupt sources, and an authentication timer circuit that starts measuring a configured time duration based upon the received signal interrupt. A scrambler module initiates data scrambling upon completion of the configured time duration.

Apparatus and method for improving data security

A method of making a reduced-depth rack server includes: forming a tray structure of a carrier having a service panel attached to two opposed side panels and a bottom panel; inserting a longest dimension of a data storage device in a sideways orientation with at least one electrical connector of the data storage device proximate to a selected lateral panel; electrically connecting a first electrical connector of an interposer cable to the at least one electrical connector of the data storage device; and attaching a second electrical connector attached to one of the tray structure and the data storage device directed towards an insertion end of the data storage assembly in an orientation opposite to the service panel and aligned to electrically connect with a backplane of a reduced-depth rack server in response to the tray structure being inserted in a rack server chassis.

A system for dynamic discharging to detected derated battery cells. In such a system, a battery cell capacity, cell voltage, as well as a time to discharge are used in combination to identify good or bad battery cells. More specifically, during a dynamic discharge cycle, an accumulated discharge capacity value is calculated and monitored by a charge level battery gas gauge via analog to digital (A/D) converters and an internal discharge time value is monitored. One of the values is assigned as a fixed value and the other value is used to identify good or bad batter cells.

Systems and methods for determining the state of health for a capacitor module are provided. In some embodiments, a method for monitoring the health of a capacitor module comprising an array of capacitors is provided. The method may include steps for disabling a charger coupled to an array of capacitors of the capacitor module, determining if the capacitor module is healthy based at least on operating values of the capacitor module, and enabling a write back mode for the memory module if the capacitor module is determined to be healthy.

In accordance with embodiments of the present disclosure, an information handling system may include a primary persistent memory comprising a volatile memory for storing data and a non-volatile memory for receiving data transferred from the volatile memory in response to a power loss of the information handling system. The information handling system may also include an alternate persistent memory instructions embodied in non-transitory computer readable media, the instructions for causing a processor communicatively coupled to the primary persistent memory and the alternate persistent memory to, responsive to a vulnerability of a persistence of the primary persistent memory, transfer application data from the primary persistent memory to the alternate persistent memory.

A reduced-depth rack server for a reduced depth rack includes a data storage device rotated a quarter turn within a carrier. An interposer cable connects at one end to a laterally presented electrical connector of the data storage device and presents another connector to an end that is inserted inwardly into a rack server chassis to electrically connect with a backplane of the reduced-depth rack server. In one embodiment, a data storage assembly of the data storage device, carrier and interposer cable is inserted from a front end of the chassis. In one embodiment, the data storage assembly is inserted from a top of the chassis to facilitate airflow.

A basic input/output system may be configured to, during boot of an information handling system in a pre-operating system environment of the information handling system, calculate an amount of energy required to perform a persistent memory save operation in a persistent memory of the information handling system in order to transfer data from a volatile memory of the persistent memory communicatively coupled to the processor to a non-volatile memory of the persistent memory communicatively coupled to the volatile memory, cause charging of an energy storage device for providing electrical energy to perform persistent memory save operations at least until a charging level of the energy storage device satisfies the amount of energy, and boot to an operating system of the information handling system responsive to the charging level of the energy storage device satisfying the amount of energy.

In some embodiments, a method for controlling a cache having a volatile memory and a non-volatile memory during a power up sequence is provided. The method includes receiving, at a controller configured to control the cache and a storage device associated with the cache, a signal indicating whether the non-volatile memory includes dirty data copied from the volatile memory to the non-volatile memory during a power down sequence, the dirty data including data that has not been stored in the storage device. In response to the received signal, the dirty data is restored from the non-volatile memory to the volatile memory, and flushed from the volatile memory to the storage device.

Systems and methods for non-volatile cache control

Systems and methods that may be implemented for time-based management of storage memory controller (e.g., RAID controller) backup battery life in information handling systems by limiting the backup battery system operation time in order to save energy, reduce the impact of leakage current, and prolong memory controller backup battery shelf life while at the same time meeting requirements of back-up time for storage/server applications. The disclosed systems and methods may be implemented, for example, by providing a battery system controller that implements a pre-set memory controller backup battery operation time, in combination with a hardware-controlled mechanism that extends backup battery system operation time by disabling one or more current leakage paths within the storage memory controller circuitry.

Determining whether there exists an input-output (I/O) fabric conflict (mismatch) between a blade I/O fabric daughter card of a blade compute module and an I/O interface module of a blade compute module system, and if a conflicts does exit then taking action to correct this I/O fabric mismatch. An I/O fabric router may be coupled between the blade I/O fabric daughter cards and the system I/O interface modules. If a matching I/O interface fabric exists then the I/O fabric router will couple the blade I/O fabric daughter card to the matching I/O interface fabric. If there is no matching I/O interface fabric then the blade I/O fabric daughter card may be decoupled from the blade compute module system so that the associated blade compute module may otherwise function, and an alert may be sent regarding the I/O fabric conflict (absence of an I/O fabric match) for the I/O fabric daughter card of the blade compute module.

Methods and systems are disclosed for utilizing a memory control circuit for controlling transfer of data to and from a memory system. A memory control circuit with a back up battery and control circuits is provided. Battery health is determined through a discharge cycle of the back up battery. A power supply generated from the back up battery is provided to circuitry of the memory control card during normal operations of the memory control circuit during a non-power loss state. The power supplied from the back up battery during the non-power loss state of the memory control circuit is utilized by at least a first circuit of the memory control circuit as part of normal memory controller card operations during the battery health discharge cycle. When the system is not performing a battery health cycle the first circuit receives normal system power. The memory control circuit may be a RAID card. The first circuit may be memory circuitry. The backup battery discharge rate may be regulated during the battery health discharge cycle by switching the power source for the circuitry of the memory control card between the backup battery and the normal system power.

A quick conditioning cycle system to avoid performance degradation at the end of calibrating cycle. The quick conditioning cycle system discharges a battery to a level where battery remaining capacity is still high enough to backup memory at a guaranteed period of time. During the quick learning cycle, the battery pack is discharged from a full charge. If measured capacity exceeds a predetermined threshold (Cpc), calibration stops. Otherwise, the quick conditioning cycle system reports a defected battery when measured capacity is less than Cpc and continues discharging to a full conditioning cycle, if desired.
