[[PageOutline]] = mSATA (SSD) / SATA / Storage = Several Gateworks products support SATA and mSATA. For microSD card support, see [wiki:ventana/simsd here] == mSATA == mSATA cards are miniPCIe form-factor (electrical and mechanical) cards that use SATA signalling on the PCIe signals and typically use flash based storage (Solid State Disk or SSD). == Ventana == '''Note''' - ''mSATA requires a quad-core processor on Ventana'' '''Note''' - ''For configuring, jump to [#VentanaSoftware]'' Many of the Gateworks Ventana boards support mSATA. Because mSATA routes SATA signals to a miniPCIe socket, these boards use a software controllable mux to decide if mSATA or PCIe should be routed to a specific miniPCI socket on the board. The bootloader 'hwconfig' command (see [wiki:ventana/bootloader#mSATAenable here]) is used to configure this mux at boot time because if PCI is desired, the bus is enumerated only once at boot time. Ventana boards with mSATA support: * GW5520-SP308 (IMX6Q) J6 (Bottom Left socket) * GW54xx (all variants) J11 (Bottom Left socket) * GW5304 (fully loaded with IMX6Q) J9 (Bottom Left socket) Notes: * SATA II 3Gbps interface supports Mini-PCIe mSATA disk drive * Gateworks would expect any SATA 3.0 mSATA to work * Only 1 miniPCIe socket supports mSATA - see the PCB silkscreen or hardware reference manual to determine which (if not specified above) * Drives are currently available from a variety of manufactures including Toshiba, Samsung, HP, Intel, !SanDisk and Dell. * The selection between the standard PCIe interface and the mSATA interface is under software control using the i.MX6 GPIO[2]:DIO[8] digital I/O signal, which is configured by the bootloader on powerup via the '[wiki:ventana/bootloader#mSATAenable hwconfig]' command. * Gateworks tests with a mSATA Crucial CT032M4SSD3 32GB SATA SSD: http://www.amazon.com/Crucial-mSATA-Internal-Solid-CT032M4SSD3/dp/B0082PVK8Q The internal IMX SATA controller supports the following features: * Compliant with the following specifications: * Serial ATA 3.0 * AHCI Revision 1.3 * AMBA 2.0 from ARM * SATA 1.5 Gb/s and SATA 3.0 Gb/s speed. * eSATA (external analog logic also needs to support eSATA) * RX data buffer for recovered clock systems * Data alignment circuitry when RX data buffer is also included * OOB signaling detection and generation * 8b/10b encoding/decoding * Asynchronous signal recovery, including retry polling * Power management features including automatic partial-to-slumber transition * BIST loopback modes === Ventana Software === * '''Note''' - '''' Please see the bootloader for configuring mSATA [wiki:ventana/bootloader#HardwareConfigurationhwconfig]'' * If configured correctly device will show up most likely as a device {{{/dev/sdX}}} in the operating system , etc (sdb,sdc,sdd,sde) (where sd stands for storage device and a is an identifier) === Ventana mSATA Performance === See the following link for some read/write performance numbers for mSATA SSD drives on Ventana: [wiki:boot_speed#StorageDevicePerformancenocodechanges] == Laguna == Laguna has support for SATA on the GW2388 [http://www.gateworks.com/product/item/laguna-gw2388-4-network-processor] * SATA Serial ATA 2.6 port * The GW2388 includes a SATA factory ordering option. This option adds a Serial ATA data connector for supporting SATA 1.5Gbps Generation 1 and 3Gbps Generation 2 speeds. The SATA port is compliant with Serial ATA 2.6 and AHCI 1.1. * Please consult the user manual for more information [http://www.gateworks.com/product/item/laguna-gw2388-4-network-processor] === Laguna Software === * If configured correctly device will show up most likely as a device {{{/dev/sdX}}} in the operating system , etc (sdb,sdc,sdd,sde) (where sd stands for storage device and a is an identifier) = PCIe based Storage = Various cards exist that implement a SATA interface over the PCIe bus.
