Managing firmware in a computing system storing a plurality of different firmware images for the same firmware includes: calculating, for each firmware image in dependence upon a plurality of predefined factors, a preference score; responsive to a failure of a particular firmware image, selecting a firmware image having a highest preference score; and failing over to the selected firmware image.

Propagating firmware updates in a RAID array including identifying, by a RAID controller, that a first drive has a firmware that is uplevel with respect to firmware of at least one other drive, the RAID controller comprising a module of automated computing machinery; selecting, by the RAID controller, a second drive having downlevel firmware with respect to the firmware of the first drive; obtaining, by the RAID controller, an uplevel firmware image from the first drive; and updating, by the RAID controller, the downlevel firmware on the selected second drive with the obtained firmware image.

Data associated with a workload is stored in a first composite array of data storage devices that meets first data storage requirements of the workload, and is automatically stored in a second composite array in response to detecting second data storage requirements of the workload, wherein the second composite array of data storage devices meets the second data storage requirements. The data may be stored in the second composite array by either converting the first array or migrating the data to another array that more closely meets the current data storage requirements of the workload. Alternatively, the array conversion or the data migration may be performed in response to a predictive failure alert from one of the data storage devices in the first composite array.

Checkpoint snapshots of segments of system memory are taken while an operating system is booting in a computer system. The segments of system memory are stored in non-volatile memory as hibernation files. In response to detecting a request for a system reboot of the OS, an affected hibernation file, which corresponds to an affected segment of system memory that will change during the system reboot of the OS, is identified. A restoration of the system memory via a wake-up from hibernation is then initiated. The wake-up from hibernation proceeds until the affected hibernation file is reached, such that initial steps in the system reboot are bypassed. Thereafter, subsequent steps, which are after the bypassed initial steps in the system reboot, are executed.

A computer program product is provided, including computer usable program code for running a plurality of virtual machine workloads across a plurality of servers within a common power domain, and computer usable program code for setting an operating level for each of a plurality of hardware resources within the common power domain in response to receiving an early power off warning from a power source that supplies power to the common power domain, wherein the operating level for each of the hardware resources is determined as a function of the priority of the virtual machine workloads that are utilizing each of the hardware resources.

Propagating firmware updates in a peer-to-peer network including identifying, that one or more nodes in the network have firmware that is uplevel with respect to the downlevel node; broadcasting an update request requesting an update to the firmware; receiving, from a plurality of nodes having firmware uplevel with respect to the downlevel node, a plurality of portions of the update, metadata describing each portion of the update received, and metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node; determining, in dependence upon the metadata describing each portion of the update received and the metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node, whether the portions of the update received comprise an entire update; and updating the firmware if the portions of the update received comprise the entire update.

In one embodiment, a fixed chassis power budget is dynamically allocated to a plurality of servers inserted into a multi-server chassis. An inserted server may be inventoried by sequentially identifying server components, categorically-defined component power limits, and actual component power requirements of the inventoried components. A power permission may be granted to the inserted server prior to completion of the inventory, based on power-related information inferred from a chassis and server specification or from the inventoried components.

In one embodiment, a computer system has a plurality of chassis interconnected by cables. Each cable initially connects a unique port pair consisting of a port of one chassis and a port of another chassis. The disconnection of cables is monitored, including electronically recording a disconnection sequence in which the port pairs are disconnected by removing each cable from at least one port of the respective port pair. Visual guidance is provided for re-cabling the computer system by sequentially identifying the port pairs in a reversal of the disconnection sequence, wherein identifying each port pair includes illuminating visual indicators associated with the ports of each port pair with a matching illumination pattern.
