SAS3444E
LSI PCIe to SAS host adapters provide four serial ports for connection to SAS/SATA (Serial Ata) devices. Each port is capable of 3.0 Gbit/s SAS link rates and 3.0 Gbit/s SATA link rates. The Pci Express transmission and reception data rate is 2.5 Gbits/s in each direction, yielding a total bandwidth of 5.0 Gbits/s for each full-duplex lane. The LSI PCIe to SAS host adapters are implemented using four PCI Express phys, which provide possible host-side maximum Transmission and reception rates of up to 4.0 Gbytes/s.
SAS Bandwidths
Half Duplex Full Duplex
Narrow Port (1 Lane)—300 Mbytes/s Narrow Port (1 Lane)—600 Mbytes/s
Wide Port (2 Lanes)—600 Mbytes/s Wide Port (2 Lanes)—1200 Mbytes/s
Wide Port (4 Lanes)—1200 Mbytes/s Wide Port (4 Lanes)—2400 Mbytes/s
PCI Express Features
The PCI Express features of the LSI PCIe to SAS host adapters include:
• Provides four (boards using LSISAS1064E) or eight (boards using
LSISAS1068E) PCI Express phys
• Supports a single-phy (1 lane) link transfer rate up to 2.5 Gbits/s in
each direction
• Supports x8, x4, and x1 link widths
• Automatically downshifts to a x4 link width if plugged into a x4
connector or into a x8 connector that is wired as a x4 connector
• Provides a scalable interface
– Single-lane aggregate bandwidth of up to 0.5 Gbytes/s
(500 Mbytes/s)
– Quad-lane aggregate bandwidth of up to 2.0 Gbytes/s
(2000 Mbytes/s)
– 8-lane aggregate bandwidth of up to 4.0 Gbytes/s
(4000 Mbytes/s)
• Supports serial, point-to-point interconnections between devices
– Reduces the electrical load of the connection
– Enables higher transmission and reception frequencies
• Supports lane reversal and polarity inversion
• Supports PCI Express Hot Plug
Supports Power Management
– Supports PCI Power Management 1.2
– Supports Active State Power Management (ASPM), including the
L0, L0s, L1 states, by placing links in a power-savings mode
during times of no link activity
Contains a replay buffer that preserves a copy of the data for
retransmission in case a CRC error occurs
• Supports the PCI Express Advanced Error Reporting capabilities
• Uses a packetized and layered architecture
• Achieves a high bandwidth per pin with low overhead and low latency
• PCI Express is software compatible with PCI and PCI-X software
– Leverages existing PCI device drivers
– Supports the Memory, I/O, and Configuration address spaces
– Supports memory read/write transactions, I/O read/write
transactions, and configuration read/write transactions
• Provides 4 Kbytes of PCI Configuration address space per device
• Supports posted and non-posted transactions
• Provides quality of service (QOS) link configuration and arbitration
policies
• Supports Traffic Class 0 and one virtual channel
• Supports Message Signaled Interrupts (both MSI and MSI-X) as well
as INTx interrupt signaling for legacy PCI support
• Supports end-to-end CRC (ECRC) and Advanced Error Reporting

The LSI PCIe to SAS host adapters use the Fusion-MPT architecture for
all major operating systems, which allows for thinner drivers for better
performance. To obtain a device driver that supports your operating
