Serial ATA (SATA) and Serial Attached SCSI (SAS) are data storage protocol standards that have the primary function of transferring data (directly or otherwise) between the host system and mass storage devices (e.g., hard disk drives, optical drives, and solid-state disks). These serial storage protocols offer several advantages over older parallel storage protocol (ATA and SCSI) interfaces:
- Faster data transfer
- Ability to remove or add devices while operating (hot swapping)
- Hot swapping can only occur when it is supported by the operating system
- Thinner cables for more efficient air cooling
- Increased operation reliability
Intel® FPGA SATA and SAS
Intel developed SATA and SAS solutions based on the latest FPGAs with transceivers. Stratix® V GX, Stratix IV GX, Arria® V, Arria II GX, Arria II GZ, Cyclone® V, and Cyclone IV GX FPGAs support the electrical and signal requirements for SATA and SAS (see Table 1). Intel FPGAs, coupled with SATA and SAS intellectual property (IP), offer a solution for developing storage interfaces on a single chip.
