20080209099 | APPARATUS AND METHODS FOR CLUSTERING MULTIPLE INDEPENDENT PCI EXPRESS HIERARCHIES - Apparatus, systems and methods for clustering multiple PCI Express hierarchies to enable access of components in different hierarchies. Each PCI Express hierarchy includes a root device as well as a cluster port for coupling each hierarchy to each other hierarchy of a physical cluster through a PCI Express switched fabric. Memory addresses and transaction IDs are re-mapped by the cluster port of each hierarchy to partition the PCI Express space of the system of multiple hierarchies. A first portion of the partitioned space is reserved for access to local components within a hierarchy. A second portion of the space is used to access remote components of other hierarchies from within a different first hierarchy. The address and transaction ID values exchanged in such remote transactions are re-mapped and used by the cluster port of each hierarchy to route exchanges between hierarchies using standard PCIe root devices, endpoint devices, and switches. | 08-28-2008 |
20090248942 | Posted Memory Write Verification - A method for verifying the proper communication of data packets from an initiator device on a PCIe data bus to a target device on the data bus. A target-specific counter on the initiator is synchronized to an initiator-specific counter on the target with the same value. The initiator writes the value of the target-specific counter into the tag field of the packet header, and also writes an identifier of the initiator into the header. Then the initiator sends the packet to the target on the PCIe data bus. Upon receipt of the packet, the target reads the identifier and checks the value against the appropriate initiator-specific counter on the target. When the value is not equal to the initiator-specific counter on the target, then it generates an error message. An additional memory write with specific data is posted from the initiator to the target. A memory read is posted of the additional memory write location from the initiator to the target. The operation of the initiator is continued when a good status and data matching the additional write data is returned from the target, and operation is halted when an error status is returned or data that does not match the additional write data. | 10-01-2009 |
20100191910 | APPARATUS AND CIRCUITRY FOR MEMORY-BASED COLLECTION AND VERIFICATION OF DATA INTEGRITY INFORMATION - Apparatus and circuitry are provided for supporting collection and/or verification of data integrity information. A circuitry in a storage controller is provided for creating and/or verifying a Data Integrity Block (“DIB”). The circuitry comprises a processor interface for coupling with the processor of the storage controller. The circuitry also comprises a memory interface for coupling with a cache memory of the storage controller. By reading a plurality of Data Integrity Fields (“DIFs”) from the cache memory through the memory interface based on information received from the processor, the DIB is created in that each DIF in the DIB corresponds to a respective data block. | 07-29-2010 |
20110238938 | EFFICIENT MIRRORING OF DATA ACROSS STORAGE CONTROLLERS - A method includes multicasting an Input/Output (I/O) data associated with a host computing device through a multicast device associated with a storage controller coupled to another storage controller in a redundant configuration, and minoring, through the multicasting, the I/O data across the storage controller and the another storage controller through a bus utilized to couple the storage controller and the another storage controller. The method also includes transmitting an early write status message to the host computing device following the minoring of the I/O data across the storage controller and the another storage controller. The early write status message is associated with a successful completion of the mirroring of the I/O data across the storage controller and the another storage controller prior to the I/O data being written to a storage device associated therewith. | 09-29-2011 |

20130205065 | METHODS AND STRUCTURE FOR AN IMPROVED SOLID-STATE DRIVE FOR USE IN CACHING APPLICATIONS - Methods and structure for an improved solid-state drive (SSD) for use in caching applications. An improved SSD comprises both volatile and non-volatile memory. The volatile memory provides improved performance as compared to present SSDs for use in caching application. The improved SSD senses impending failure of external power applied to the SSD and, while adequate power remains, copies cached data from the volatile memory to the non-volatile memory to retain the data through the power loss. In some embodiments, a local power source may be present to assure sufficient time for the SSD to save cached data in the non-volatile memory. Since the volatile memory (e.g., DRAM) is used for the primary caching function and the non-volatile memory is rarely used, performance, reliability and cost goals are achieved for write cache applications. | 08-08-2013 |
