MANAGEMENT OF PARTIAL DATA SEGMENTS IN DUAL CACHE SYSTEMS |
| 摘要 |
For movement of partial data segments within a computing storage environment having lower and higher levels of cache by a processor, a whole data segment containing one of the partial data segments is promoted to both the lower and higher levels of cache. Requested data of the whole data segment is split and positioned at a Most Recently Used (MRU) portion of a demotion queue of the higher level of cache. |
