XMC Mezzanine Module – SATA Storage • Quad-Channel SATA III 6Gbps Controller

  • dx2

The DX2-COUGAR is a XMC style mezzanine card, equipped with a four-channel PCI Express® to SATA 6Gbps controller, and one or two on-board 1.8-inch Micro SATA solid state drives (SSD) as an option. The Marvell® SATA 3.0 controller allows RAID or non RAID operation, and incorporates speed negotiation to backward support 3Gbps and 1.5Gbps. Two front bezel eSATA connectors are provided for attachment of external SATA storage devices. The other two SATA ports are reserved for 1.8-inch size Micro SATA on-board drives. As of current, suitable on-board mounting Micro SATA solid state drives are available with up to 512GB Flash storage capacity each, and up to 6G SATA III interface speed (please refer to e.g. Micron®, Intel®). A single drive can be optionally mounted on the DX2-COUGAR component side (XMC side 1, facing the carrier board when module is engaged). In addition, a second drive may be accommodated on the back side of the mezzanine card (module side 2, on top of the stack when assembly is mounted).
The DX2-COUGAR connects SATA III devices to a PCIe 2.0 host, delivering up to 1 Gigabyte-per-second (GBps) bandwidth when a two-lane 5.0 Gbps interface is available. In addition, hardware RAID operation is supported, running with an enhanced ARM-based processor to offload the host CPU, and Marvell® HyperDuo technology for automated SSD/HDD tiering.
The DX2-COUGAR can accommodate one or even two 1.8-inch microSATA standard form factor drive(s) according to the SFF-8144 specification, which results in a 5.0 mm maximum height, and 78.5mm x 54.0mm dimensions.
A mounting frame is used to hold each drive, for extremely rugged applications.
