Marvell 88SE1495 PCIe 3.0 to 16-port 12Gb/s SAS/SATA I/O Host Controller Enterprise Class Host Storage Controllers PRODUCT OVERVIEW Marvell® is a leading provider of Serial Attached SCSI (SAS) and Serial ATA (SATA) host controller silicon and software solutions for desktops, workstations, servers, external and cold/cloud storage systems. As a latest addition to its full range of flexible storage solutions, the Marvell 88SE1495 chip delivers an eight-lane PCIe 3.0 to 16-port 12Gb/s SAS/SATA I/O controller with exceptional performance and industry-leading features. Marvell’s advanced proprietary chip design enables the Marvell 88SE1495 to achieve the industry’s best jitter performance and lowest per-port power consumption. The 16 high-performance SAS/SATA PHYs on Marvell 88SE1495 are capable of 1.5 Gps, 3.0 Gps, 6.0 Gps and 12.0 Gps SAS/SATA link rates, offering the best flexibility and protection of prior investment for entry to mid-range servers. The Marvell 88SE1495 controller supports both the ANSI SAS 3.0 protocol through native SAS connection and the Serial ATA protocol through tunneled connection. It includes two independent XOR engines enabling hardware-assisted RAID 5 and RAID 6 with I/O acceleration and CPU utilization reduction for enterprise-level usage. The device is also equipped with Marvell Windows/Linux non-RAID binary drivers for ease-of-use and fast product development. 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps 12 Gbps BLOCK DIAGRAM 16 SAS/SATA 12Gb/s Ports TWSI Enclosure Mgmt PM Control FIS Based Switching Flash SAS STP/SMP/ SSP GPIO (LEDs) XOR x 2 OSC PCIe 3.0 PCIe 3.0 x 8 Fig 1.
