SAS Port Bandwidths
■
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 plugging
■
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 when there is no link activity
■
Contains a replay buffer that preserves a copy of the data for retransmission in case a
cyclic redundancy check (CRC) error occurs
■
Supports the PCI Express advanced error-reporting capabilities
■
Uses a packetized and layered architecture
■
Achieves high bandwidth per pin with low overhead and low latency
■
Provides software compatibility 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 KB of PCI configuration address space per device
■
Supports posted and nonposted 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
