6Gb/s SAS/SATA IO Controllers
Marvell® offers a range of Serial Attached SCSI (SAS) host controller silicon and software solutions for desktops, workstations, servers and external storage systems. The controller silicon incorporates Marvell industry-leading 6 Gb/s SAS/Serial ATA (SATA) PHY technology and 5 GT/s PCI Express 2.0 (PCIe) PHY cores, which combine the best jitter performance and lowest per-port power consumption available today. Additionally, Marvell has invested heavily in the development of a full suite of high-performance, highly scalable, fault-tolerant RAID and storage management software.
The Marvell SAS 6Gb/s host controllers support four or eight SAS/SATA ports, including native 6Gb/s SATA interface support, and as many as eight lanes of PCIe 2.0 connectivity, delivering up to 4GB/s bandwidth to the host system for high-performance demanding applications. It incorporates a RAID offload engine to reduce CPU utilization when running at RAID configurations, thereby increasing overall system performance. The devices are offered with Windows/Linux non-RAID binary drivers and Linux open source driver for ease-of-use and fast product development.
