Some servers are also starting to appear with serial attached SCSI (SAS) ports that can also be used for attachment of SATA storage devices. Some newer servers are sporting PCI-Express native adapter's slots eliminating PCI or PCI-X to PCI-Express bridging enabling better performance.
If your server does not have a SATA I/O port or if you need additional ports, then you could install a PCI or PCI-X SATA port to your system. However, for backwards compatibility with IDE/ATA, you would need an IDE/ATA port.
