A first nano-ESS includes a plurality of cells, a plurality of cell balancing converters, a bidirectional DC-DC converter and a nano-ESS controller. The multi-source ESS operates in a charging mode and a discharging mode.

The multi-source ESS receives power when it operates in the charging mode.

Abstract: A storage management method includes receiving a degrade signal indicating a degraded state of a virtual disk associated with a host system. Rebuild-flush operations may be performed. The operations may include writing, to the virtual disk and also to a hot spare drive (HSP) associated with the virtual disk, valid-modified data, stored in a host storage cache, associated with the virtual disk. In contrast, valid-unmodified storage cache data associated with the virtual disk, may be written to the HSP only. After the rebuild-flush completes, the virtual disk may be rebuilt. During rebuild, however, any cached-LBA may be skipped where traditional RAID rebuild operations are performed for un-cached LBAs only.

Abstract: Methods and systems for efficient rebuild of storage devices in a RAID may include generating a data-modified map of a storage device. The data-modified map may be updated when a RAID virtual device associated with the storage device is degraded to indicate write operations. The data-modified map may be used to rebuild selective portions of the storage device, instead of performing a full rebuild. The data-modified map may also be used to perform a full rebuild of the storage device.

Abstract: A disclosed storage management method includes detecting an unrecoverable failure associated with a logical block of a first physical storage device that is one of a plurality of storage devices within a redundant virtual drive that also includes a hot spare drive. Data for the unrecoverable block may be rebuilt from data in the remaining storage devices and stored in a logical block of the hot spare drive. One or more logical block maps may be maintained to identify unrecoverable logical blocks and to indicate the logical blocks and storage devices to which each of the unrecoverable logical blocks is relocated. I/O operations that access “good” logical blocks are normally while accesses to unrecoverable logical blocks are rerouted according to the logical block map. One or more unrecoverable thresholds may be supported to initiate operations to replace storage devices containing unrecoverable blocks exceeding an applicable threshold.

Abstract: A method for copying data from a storage device that has been identified for replacement or has failed to a spare storage device. The method includes a storage controller tracking input/output statistics for several storage devices. The storage controller determines if a first storage device storing first data has been identified for replacement within the storage devices. In response to the first storage device having been identified for replacement, a first least written to data address space within the first storage device is determined based on the input/output statistics. First data contained in the first least written to data address space is copied from the first storage device to the spare storage device.

Abstract: Systems, methods and computer program products are described herein for testing a system that is designed to optimize the execution of code within an application or other computer program based on profile data collected during the execution of such code. The embodiments described herein utilize what is referred to as a “profile data mutator” to mutate or modify the profile data between the point when it is collected and the point when it is used to apply an optimization. By mutating the profile data at this point, testing of a system for optimized code execution can be significantly more thorough. Furthermore, such profile data mutation leads to a more scalable and efficient testing technique for profile-guided systems for optimized code execution.

Abstract: Systems and methods are provided to track cluster nodes and provide high availability in a computing system. A computer system includes hosts, a cluster manager, and a cluster database. The cluster database includes entries corresponding to the hosts which identify the physical location of a corresponding host. The cluster manager uses the data to select at least two hosts and assign the selected hosts to a service group for executing an application. The cluster manager selects hosts via an algorithm that determines which hosts are least likely to share a single point of failure. The data includes a hierarchical group of location attributes describing two or more of a host's country, state, city, building, room, enclosure, and radio frequency identifier (RFID). The location-based algorithm identifies a group of selected hosts whose smallest shared location attribute is highest in the hierarchical group. The system updates the data whenever a physical location of a host changes.
