The SAS Initiator Controller is an advanced interface core that supports high-speed serial link replacements for the conventional parallel SCSI attachment, connecting mass storage devices with efficiency and reliability. Achieving a bandwidth of up to 48 Gbps, it utilizes multiple high-speed gigabit transceivers to maintain optimal data flow and connectivity. The core’s architecture includes support for simultaneous operation with both SAS and SATA technologies, enhancing its versatility.
It features sophisticated mechanisms for SAS & SATA speed negotiation and out-of-band (OOB) signaling, providing seamless transitions between supported speeds of 1.5, 3.0, 6.0, and 12.0 Gbps. This flexibility enables up to four ports to be operational simultaneously, offering extensive connectivity and management facilities through a native 32-bit PHY interface.
The SAS Initiator Controller handles power management, automatic connection control, and frame decoding dynamically, easing integration and operation within complex systems. This core is ideal for applications that demand robust storage solutions with minimal latency and maximum efficiency, supporting various SMP, SSP, and SATA protocols.
