Product Description 1.7 Discrete eSATA/PATA Controller The board provides a discrete Marvell* controller to support two eSATA connectors on the back panel and one PATA connector. 1.7.1 External Serial ATA Support The red Serial ATA connectors on the back panel can be used for an external SATA drive. They can also be used for port replication, which allows the aggregation of multiple hard drives on each of the eSATA ports. Figure 10 on page 44 shows the location of the External Serial ATA-compatible SATA ports on the back panel. The Marvell 88SE621 controller uses the PCI Express for data transfer with a theoretical maximum transfer rate of 3 Gbits/sec per port. These connectors are in addition to the six SATA connectors of the ICH9R SATA interface. The discrete SATA interface supports the following RAID levels: • RAID 0 • RAID 1 NOTE The Marvell 88SE621 controller supports single drive non-RAID configurations as well as RAID configurations. For RAID configurations, you must install the RAID drivers by pressing F6 during operating system installation. See your operating system installation documentation for more information about installing drivers during the installation process. For information about The location of the discrete SATA RAID connectors Refer to Figure 11, page 45 1.7.2 Parallel ATA IDE Controller The Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. The Parallel ATA IDE interface supports the following modes: • Programmed I/O (PIO): processor controls data transfer. • 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/sec. • Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec. • ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible. • ATA-100: DMA protocol on IDE bus allows host and target throttling. The ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec. 21

1.7
Discrete eSATA/PATA Controller
The board provides a discrete Marvell* controller to support two eSATA connectors on
the back panel and one PATA connector.
1.7.1
External Serial ATA Support
The red Serial ATA connectors on the back panel can be used for an external SATA
drive. They can also be used for port replication, which allows the aggregation of
multiple hard drives on each of the eSATA ports.
Figure 10 on page 44 shows the
location of the External Serial ATA-compatible SATA ports on the back panel.
The Marvell 88SE621 controller uses the PCI Express for data transfer with a
theoretical maximum transfer rate of 3 Gbits/sec per port.
These connectors are in
addition to the six SATA connectors of the ICH9R SATA interface.
The discrete SATA interface supports the following RAID levels:
•
RAID 0
•
RAID 1
±
NOTE
The Marvell 88SE621 controller supports single drive non-RAID configurations as well
as RAID configurations. For RAID configurations, you must install the RAID drivers by
pressing F6 during operating system installation. See your operating system
installation documentation for more information about installing drivers during the
installation process.

1.7.2
Parallel ATA IDE Controller
The Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface.
The
Parallel ATA IDE interface supports the following modes:
•
Programmed I/O (PIO):
processor controls data transfer.
•
8237-style DMA:
DMA offloads the processor, supporting transfer rates of up to
16 MB/sec.
•
Ultra DMA:
DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 33 MB/sec.
•
ATA-66:
DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 66 MB/sec.
ATA-66 protocol is similar to Ultra DMA and is
device driver compatible.
•
ATA-100:
DMA protocol on IDE bus allows host and target throttling.
The ATA-100
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up
to 88 MB/sec.
