A processor blade determines whether a selected processing task is to be off-loaded to a storage blade for processing. The selected processing task is off-loaded to the storage blade via a planar bus communication path, in response to determining that the selected processing task is to be off-loaded to the storage blade. The off-loaded selected processing task is processed in the storage blade. The storage blade communicates the results of the processing of the off-loaded selected processing task to the processor blade.

Off-loading of processing from a processor blade to storage blades based on processing activity, availability of cache, and other status indicators

Off-loading of processing from a processor blade to storage blades

A method to manage power in a computing device comprising a controller assembly and a storage assembly comprising a plurality of data storage devices, by selecting a processor parameter, establishing a threshold processor parameter value, establishing a threshold over-parameter time interval, selecting a data storage device parameter, and establishing a nominal data storage device parameter value. The method determines an actual processor parameter value. If the actual processor parameter value is less than or equal to the threshold processor parameter value, the method operates each of the plurality of data storage devices using the nominal data storage device parameter value. If the actual processor parameter value is greater than the threshold processor parameter value, then the method determines an actual over-parameter time interval. If the actual processor parameter value is greater than the threshold processor parameter value, and if the actual over-parameter time interval is greater than the threshold over-parameter time interval, then the method operates each of the plurality of data storage devices using a data storage device parameter value less than the nominal data storage device parameter value.

Apparatus and method to manage power in a computing device

A system, method, and program product is provided that requests, by a first computer system, a new network session with a second computer system. The new network session request occurs after a previous network session between the two systems and the new network session request includes a new sequence number that is different from a previous sequence number that was used during the previous network session. The first computer system receives an acknowledgement from the second computer system that references the previous sequence number instead of the new sequence number. In response to receiving the acknowledgement at the first computer system that references the previous sequence number, the first computer system modifies the new sequence number by setting it to a value that is higher than the previous sequence number, and the first computer system re-requests the new network session using the modified new sequence number.

An apparatus, system, and method are disclosed for a configurable blade card. A base card is in physical and electrical communication with a blade connector. The blade connector is in physical and electrical communication with a blade enclosure connector. A secondary card is in physical and electrical communication with the base card to form a blade card. A coupler physically couples the base card and the secondary card. The base card and the secondary card are co-planar and compatible with a blade card form factor.

A method for caching data in a blade computing complex includes providing a storage blade that includes a disk operative to store pages of data and a cache memory operative to store at least one of the pages. A processor blade is provided that includes a first memory area to store at least one of the pages and a second memory area configured to store an address of each of the pages and a hint value that is assigned to each of the pages. An address of each of the pages is stored in the second memory area, and a hint is assigned to each of the pages, where the hint is one of: likely to be accessed, may be accessed, and unlikely to be accessed. The page is then stored in storage blade cache memory based on the hint.
