The PCIe3 4 x8 SAS Port Adapter is a PCI Express (PCIe), generation 3, RAID SAS adapter. The adapters are short-form factor. The FC EJ11 is a low-profile adapter. The adapter is used in high-performance and high-density, serial attached SCSI (SAS) applications. It supports the attachment of SAS DVD or SAS tape by using four mini SAS high-density (HD) x4 connectors that allow the physical links to be used in various narrow and wide-port configurations. SAS tape attachment is only supported in a single adapter configuration and cannot be mixed with SAS disk on the same adapter.
