The Tachyon QE8 combines four ports of 8-Gbit/s Fibre Channel with eight lanes of 5-Gbit/s PCIe 2.0 bandwidth. The Tachyon QE8 achieves up to 6.4GByte/s throughput and greater than 1.4 million I/Os per second (IOPS) performance. The QE8 leverages a Tachyon State Machine architecture that combines low latency with a high level of system performance and scalability.
The QE8 integrates a host of advanced features, including native eight-lane PCI-Express 2.0 Gen-II 5Gbit/s bus; multi-DMA to enable system cache mirroring with minimal CPU overhead; frame steering for hardware assisted virtualization; multi-CPU support to extend processor scalability and to allow special frame handling within a single Fibre Channel port. The QE8 supports the T-10 Standard “Protection Information” via ADIF (Advanced Data Integrity Field) to ensure complete integrity in the I/O data path.
The Tachyon QE8 is fully interoperable with PMC-Sierra's family of 4-Gbits/s Fibre Channel products, and can be combined with its SAS/SATA protocol controllers and expanders.
PMC-Sierra provides a comprehensive Tachyon Software Development kit (TSDK), including source code and drivers, to significantly reduce firmware development time and accelerate time to market.
