Are BlueStor products SCSI or Fibre Channel?
Neither. The BlueStor™ SAS/SATA Storage Server may be used as a host for external SCSI or Fibre Channel storage devices located outside the server, with the addition of a PCI HBA or RAID controller for SCSI or Fibre Channel. However, the whole BlueStor™ concept was to get away from those costly bus interfaces and embrace new technology for 2007 and beyond. BlueStor™ products use the SAS (Serial Attached SCSI) bus internally to create a storage device interface that supports either SAS or SATA disk drives and attaches to a host computer using either a SAS or PCI Express (PCIe) interface. This reduces bottlenecks as well as reducing cost because there are no parallel to serial bridges involved at all and we can take advantage of the ever expanding bus width of PCI Express and its very robust roadmap. Using SATA-2 3 Gbps disk drives available “today” we can build pretty large scale serial-switched storage systems inexpensively without ever bridging to Fibre Channel at all! The advantages
