XMC Mezzanine Module • Quad Channel SAS Controller

The DS1-LEOPARD is an XMC style mezzanine card, equipped with a PCI Express® to 6Gbps SAS/SATA host controller. The front bezel Mini SAS 4x connector (SFF-8088) is suitable for attachment of up to four external SAS or SATA storage devices, such as hard disk drives, solid state drives, or streamer tapes. The on-board Marvell® controller can be used with a PCIe x1, x2 or x4 lane interface up to 5GT/s. All I/O ports are compliant to Serial Attached SCSI (SAS-2.0), and in addition to Serial ATA (SATA 3.0). The DS1-LEOPARD brings a high-performance, low cost 6Gbps per port combined SAS and SATA HBA solution to embedded systems and industrial computers. The wide (4x) SAS port provides a high-performance interconnect to SAS storage systems and high-capacity SATA JBOD applications. A 4MB on-board SPI Flash memory is provided for boot code. Marvell® non-RAID software is available for download. A PCIe x4 enabled XMC carrier card is recommended for optimum data throughput.
