Constellation ES Serial ATA Product Manual, Rev. G

Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no 
master/slave relationship because each drive is considered a master in a point-to-point relationship. If two 
drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they 
were both “masters” on two separate ports. Both drives behave as if they are Device 0 (master) devices.

The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connec-
tions. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 in). See Table 7 for 
connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host.

For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive 
and the host receptacle incorporate features that enable the direct connection to be hot pluggable and blind 
mateable.

For installations which require cables, you can connect the drive as illustrated in Figure 4.

Each cable is keyed to ensure correct orientation. Constellation ES Serial ATA drives support latching SATA 
connectors.
