Abstract:
In one example, a system for server tray backup power redundancy includes an interruptible power supply and uninterruptible power supply coupled to a first server tray within a server enclosure and a second server tray within the server enclosure, wherein the uninterruptible power supply is coupled in parallel to the first server tray and the second server tray.
Abstract:
According to an example, a leakage detection system for a logic board may include a management controller apparatus that is to determine whether to shut down either or both of a cooling system for the logic board and the logic board based upon a read value of a register bit in the register of a leakage detection circuit and whether a communication is received from a logic device regarding receipt of a leakage detected signal by the logic device from the leakage detection circuit.
Abstract:
A system can include a memory to store data and machine readable instructions. The memory can include a stack comprising an array of pointers to memory blocks in a heap. The system can also include a hardware assisted garbage collector (HWAGC) to control allocation of the blocks of memory in the heap. The HWAGC can also maintain a copy of the stack and detect a dead object in the heap.
Abstract:
An example device in accordance with an aspect of the present disclosure is to identify, according to metadata, persistent data to be backed up from a plurality of volatile memory modules. The persistent data is copied from the plurality of volatile memory modules to the non-volatile storage, while excluding the non-persistent data.
Abstract:
Example implementations relate to placing loads in a self-refresh mode using a shared backup power supply. For example, a shared backup power supply system can include a node coupled to a shared backup power supply. The node can include a plurality of loads that include volatile memory and a processing resource to place the plurality of loads in a self-refresh mode in response to a failure of a primary power supply. A shared backup power supply system can also include the shared backup power supply to provide backup power to the plurality of loads in the self-refresh mode in response to the failure of the primary power supply.
Abstract:
Example implementations relate to a parallel backup power supply. For example, a parallel backup power supply system can include a plurality of backup power supply cells that support a plurality of loads. Each of the backup power supply cells can include a charging module to charge an associated backup power supply cell among the plurality of backup power supply cells and a cell controller. The cell controller is to can be configured to control the charging module and communicate with a management module. The parallel backup power supply system can also include the management module to activate each of the plurality of backup power supply cells to provide backup power in parallel to the plurality of loads as each of the plurality of backup power supply cells is fully charged.
Abstract:
A networking infrastructure center includes a networking chassis, networking switches implemented in the networking chassis via module slots, the networking switches being swappable in the module slots to create an infrastructure topology, storage switches implemented in the networking chassis via the module slots, the storage switches being swappable to create the infrastructure topology, and a shuffler, the shuffler to detect locations of the networking switches and the storage switches to allow the networking switches and the storage switches to be placed in arbitrary locations on the networking chassis and to realize the infrastructure topology by splitting the infrastructure topology via physical signal multiplexing to physically isolate the networking switches and the storage switches.
Abstract:
Example implementations relate to selectively enabling backup power to nodes. For example, a system includes a plurality of compute nodes, where each node includes a plurality of loads. The system also includes at least one backup power supply and control module coupled to the nodes and to the at least one backup power supply. The control module is to selectively enable an output of power from the at least one backup power supply to the nodes based on a comparison of a power capacity of the at least one backup power supply and a backup power demand of the nodes.
Abstract:
Example implementations relate to partitioning memory modules into volatile and non-volatile portions. For example, a system includes a memory controller to partition a memory module into a non-volatile portion and a volatile portion and to identify persistent data to be backed up during a power loss condition. The memory controller is further to transfer the persistent data from the volatile portion of the memory module to the non-volatile portion of the memory module, in response to the power loss condition.
Abstract:
Example implementations relate to data backup. For example, a data backup can include tracking a location of a data block on a first node and initiating a transfer, utilizing a backup power supply, of the data block to a non-volatile memory location on a second node in response to an interruption of a primary power supply. In addition, the data block can be restored to the tracked location of the first node responsive to a restoration of the primary power supply.
