XITC2311

Product Overview

The XITC5088 Accelerator provides high performance enterprise level data protection, data compression, data decompression, data recovery functions. This product can provide the perfect support for consumer and enterprise level computing and storage applications. The XITC5088 accelerator is designed to combine high performance with robustness and ease of use and integration. The XITC5088 is designed to allow up to six different simultaneous data operations.

This accelerator IP is designed as a block-IO device to be attached to the host either directly through a PCIe bus, or supporting multiple Hosts through a PCIe switch. The host can move data blocks to the XITC5088 accelerator SOC for data encryption, data decryption, data compression, data decompression, as well as erasure coding parity generation, erasure coding data validation and erasure coding data recovery. This SOC will also include various security functions such as Key generation (both symmetric and asymmetric), digital signing, verification, hash generation and MAC functions. XITC5088 also employs a feature to allow the Host to perform two data operations using a single data transfer, with inputting only a single command.

The ECS Coding and Data Retrieval operation is a high-performance feature specific to XITC5088. This function allows for high speed data recovery of multiple data segments/drives by using a reduced number of “Parity” Drives specified by the Host. This ECS operation uses polynomials, Galois Field (GF) values, as well as exponential, logarithmic and matrix math functions to provide a very efficient storage method, allowing for recovering data from multiple, simultaneous drive failures.
