Abstract: In one embodiment, a method includes receiving, by a first router, data from a network component. The method also includes determining, by the first router, a first link bandwidth capacity between the first router and a host device and determining, by the first router, a first score for the first router based on the first link bandwidth capacity. The method also includes determining, by the first router, a second link bandwidth capacity between a second router and the host device and determining, by the first router, a second score for the second router based on the second link bandwidth capacity. The method further includes comparing, by the first router, at least the first score and the second score to determine a highest score and assigning, by the first router, an edge router associated with the highest score to communicate the data to the host device.

Abstract: A method is performed by a network controller. The method includes receiving information that defines a topology of a network having Ethernet Segments configured with virtual local area networks (VLANs) and including provider edges that are multi-homed to customer edges. The method further comprises, based on the topology, determining for the VLANs particular provider edges among the provider edges that are to operate as designated forwarders of traffic for the VLANs, such that the VLANs are load balanced across the particular provider edges. The method also includes programming the particular provider edges as the designated forwarders of traffic for the VLANs.

Abstract: A performance metric of a data shard stored in a first storage portion is monitored. It is determined that the performance metric of the data shard exceeds a threshold. In response to the determination that the performance metric exceeds the threshold, the data shard is reassigned to a second storage portion selected based on an over-provisioning bias of the second storage portion that is different than an over-provisioning bias of the first storage portion or the over-provisioning bias of the first storage portion is increased.

Abstract: A method for allocating workloads based on a total cost of ownership (TCO) model includes receiving a workload; estimating a cost for allocating the workload to each disk of disks in a disk pool based on a TCO model; determining a disk among the disks in the disk pool that minimizes a TCO; and allocating the workload to the disk. The TCO model incorporates a plurality of cost factors for estimating costs for each disk in the disk pool for allocating the workload.

Abstract: A method for migrating disks includes: dividing a disk pool including a plurality of disks into a random zone and a sequential zone based on sequentiality and randomness of workloads running on the plurality of disks; monitoring a status of each disk in the disk pool based on a total cost of ownership (TCO); migrating one or more workloads of an overheated disk to an idle disk based on the status of each disk. The overheated disk has a first TCO higher than a migration threshold, and the idle disk has a second TCO lower than an idling threshold.

Abstract: Embodiments of the inventive concept include a solid state drive (SSD) shared array memory cache system including memory cache occupancy prediction. The system can include multiple SSD modules each including a non-volatile memory section, a cache, and a prediction agent generator logic section. The system can further include a host agent including an occupancy prediction logic section that can receive prediction agents from the prediction agent generator logic section of each of the SSD modules, and predict content occupancy of the cache based at least on the prediction agents. A method for predicting SSD memory cache occupancy can include processing write requests, predicting content occupancy of an SSD's cache, determining whether an address in the cache is probably logically contiguous to the logical memory address, re-directing at least one write request, and coalescing multiple write requests including the re-directed write request into a single I/O for storage on the non-volatile memory of the SSD.

Abstract: A data processing apparatus and method are provided for detecting cache misses. The data processing apparatus has processing logic for executing a plurality of program threads, and a cache for storing data values for access by the processing logic. When access to a data value is required while executing a first program thread, the processing logic issues an access request specifying an address in memory associated with that data value, and the cache is responsive to the address to perform a lookup procedure to determine whether the data value is stored in the cache. Indication logic is provided which in response to an address portion of the address provides an indication as to whether the data value is stored in the cache, this indication being produced before a result of the lookup procedure is available, and the indication logic only issuing an indication that the data value is not stored in the cache if that indication is guaranteed to be correct.

Abstract: A data processing apparatus is provided having processing logic for performing a sequence of operations, and a cache having a plurality of segments for storing data values for access by the processing logic. The processing logic is arranged, when access to a data value is required, to issue an access request specifying an address in memory associated with that data value, and the cache is responsive to the address to perform a lookup procedure during which it is determined whether the data value is stored in the cache. Indication logic is provided which, in response to an address portion of the address, provides for each of at least a subject of the segments an indication as to whether the data value is stored in that segment. The indication logic has guardian storage for storing guarding data, and hash logic for performing a hash operation on the address portion in order to reference the guarding data to determine each indication.
