Why all the focus on PCIe and SAS/SATA?
Well, PCIe is already the de facto I/O interconnect standard. It’s well supported by an active Special Interest Group and has a robust roadmap for many years. PCIe supports all PCI-compatible software, is highly scalable and supports component hot-swap. We expect that in the future, servers will have an “external PCIe” slot available which will eliminate the need for even a host card. SAS provides SCSI Enterprise performance and robustness using the SCSI command set but is serial switched architecture, reducing backplane and cabling complexities, eliminating the need for terminators and providing a great many benefits over previous generation storage buses. SATA drives are compatible with SAS and are very high capacity for low cost, allowing users to build large arrays using BlueStor™ with resulting system cost well under one dollar per GB. Marrying PCIe to SAS is a logical evolutionary step. While PeSAN™ is unique in concept, it’s technically very sound and the data storage industry i
