entry-level to mid-range servers and non-mission critical network storage. With the introduction of SATA products in 2004, key solution providers like HP are now offering more scalable and affordable configuration options for a broad range of storage applications. This technology brief begins with - HP 460355-B21 | Serial ATA technology, 2nd edition - Page 3
It is becoming increasingly difficult to support the traditional 5V TTL signal requirement the data signals transmitted between the host and HDD controller. However, ATA command signals are not checked with CRC parallel wires from the initiator to the target device at a specific signaling rate. As - HP 460355-B21 | Serial ATA technology, 2nd edition - Page 4
into the data stream, thus eliminating the skew problem with aligning data and clock signals. Serial architectures require serializer/deserializer (SerDes), contains a parallel digital interface, First-In-First-Out (FIFO) caches, 8 bit/10 bit (8b/10b) encoder and decoder, a serializer, and a - HP 460355-B21 | Serial ATA technology, 2nd edition - Page 5
SATA devices for server and networked storage applications. Theoretically, with the use of port multipliers, each port on a SATA 3.0 Gb/s host controller can connect up to 15 SATA drives.

Cabling and connector SATA replaces the parallel ATA 40-pin connector and 18-inch long flat ribbon cable with a 7-pin connector (four signal lines SATA controllers typically have two ports for connection to internal SATA devices while a SATA HBA can have a number of ports for internal or - HP 460355-B21 | Serial ATA technology, 2nd edition - Page 7
