Federating and protecting multiple big data sources combined with enterprise data sources for BI

摘要

In an embodiment, a method provides first and second storage pools having a plurality of corresponding storage blocks to a storage solution. The method monitors each storage block of the first plurality for an indication of failure by either (a) simultaneously writing a same data to a storage block of the first plurality and a corresponding storage block of the second plurality and, if writing the same data to the corresponding storage block of the second plurality completes before writing the same data to the storage block of the first plurality, indicating the first plurality of storage to be failed or (b) employing an internal procedure of the storage solution. The method, upon determining the indication, replaces the storage block with an unused storage block from a plurality of backup storage blocks or declaring the entire storage solution at a lower performance level.

主权项

1. A method of storing data comprising:
providing a first pool of storage having a plurality of storage blocks to a storage solution; providing a second pool of storage having a plurality of storage blocks to the storage solution, each of the second plurality of storage blocks corresponding to one or more of the first plurality of storage blocks, each storage block being a device or a field replaceable unit (FRU); monitoring each of the first plurality of storage blocks for an indication of failure by simultaneously writing a same data to a particular storage block of the first plurality and a corresponding particular storage block of the second plurality and, if writing the same data to the corresponding particular storage block of the second plurality completes before writing the same data to the particular storage block of the first plurality, indicating the first pool of storage to be failed; and upon determining an indication of failure of a particular storage block, replacing the particular storage block with an unused storage block from a plurality of backup storage blocks or declaring the entire storage solution at a lower performance level.
