[[PageOutline]] = GW3089 GBlade Server Blade [[Image(gw3090rack.jpg,300px)]] [[Image(GW3089.png,100px)]] == Product Information Gateworks main website product information and datasheet can be found here: [https://www.gateworks.com/products/arm-server-blades/gblade-arm-server-blade/ Link] == Getting Started The GBlade is pre-installed with Ubuntu Linux. You must access the serial console for initial configuration. The following steps are required when bringing up new units. === Power Gblade over active PoE Isolated 802.3at 1GbE active PoE is supported on the bottom 1GbE Ethernet port. The Gateworks GW10144 802.3at PoE power supply/inserter can be used to power individual units and/or during development. See link here for info on GW10144: [https://tsi.tyconsystems.com/doc/SpecSheets/TP-POE+10G__53V_30W_10GB_PoE_Inserter_Spec_Sheet.pdf Tycon Inserter]. Typical power consumption is around 10-13W without any additional cards plugged into the NVME socket. For rackmount applications a 802.3at PoE switch is recommended. To use the 10GbE port for PoE powering the device, please contact Gateworks Sales. === Status LED Indicator Once power is applied and the bootloader start loading the OS, the LED status indicator on the frontplate will turn on solid green. Once Linux is fully loaded this LED will flash (heartbeat) indicating that the OS has fully loaded. === Serial Console Access Once the unit is powered, the GBlade serial console can be accessed through the type C USB port through a cable to a desktop/laptop PC. The serial console uses an industry standard FTDI FT2232HQ USB to Serial/JTAG converter IC and will show up as a /dev/ttyUSBx device in Linux and can be accessed through a terminal program with the baud rate of 115,200. For other operating systems, such as Windows, virtual COM port (VCP) drivers can be found here: [https://ftdichip.com/drivers/vcp-drivers/ Link]. {{{ jammy-malibu login: root Password: root }}} [[Image(serial.JPG,300px)]] Example: {{{ sudo screen /dev/ttyUSB1 115200,cs8 }}} === SSH Enabling The default Ubuntu BSP has SSH disabled. If access over the management port is desired the user must enable SSH using the serial console. See instructions below. The {{{openssh-server}}} package provides an ssh daemon suitable for secure shell (ssh) and secure copy (scp): {{{ #!bash apt-get install openssh-server }}} To enable root ssh capability, which is disabled by default, do the following: Edit /etc/ssh/sshd_config, and comment out the following line: {{{ #!bash PermitRootLogin without-password }}} Just below it, add the following line: {{{ #!bash PermitRootLogin yes }}} Then reload SSH config: {{{ #!bash service ssh reload }}} === Connecting Ethernet There are two Ethernet ports, 1GbE (management) and 10GbE (high speed data). * (eth1) 1GbE RGMII port is on the bottom (PoE by default) - Note this interface is not enabled in the default Linux installation and will need to be enabled if user wants to use this interface for both power and management. * (eth0) 10GbE XFI port is on the top - This port is brought up with DHCP enabled in the default Linux installation. [[Image(ethernet.JPG,300px)]] 6. Installing and Customizing Software Any server software (LAMP stack, etc) can then be installed using the Ubuntu package manager. {{{ apt-get update apt-get install {your package} }}} == USB Port The Type-C USB port is only for serial console and JTAG access. This port will not work as a standard USB port. See serial console access above for more information. == NVME Socket The GBlade contains a M.2 2280 PCIe Gen 3 x4 lane socket that can be used to support NVME drives, accelerator cards and radio cards (ie. AI accelerators, SDR radios, etc..). For volume orders contact sales for pre-installed options. To load your own NVME drive you will need to be opened up the enclosure. Here are the steps to open the enclosure and access the NVME socket. 1. Remove the four frontplate screws using a T8 Torx driver. 2. Remove the frontplate and move to the side. Note the LED cable does not need to be removed. 3. Slide out the side plate on the backside of the board (this is the side that the LED cable is mounted on). 4. The M.2 NVME socket should now be visible and a drive can be inserted. Secure the drive to the PEM towards the front of the unit and reinstall the frontplate making sure the LED cable does not get pinched by any of the plates. 5. The NVME drive should now show up as /dev/nvme0 and /dev/nvme0n1 respectively in Linux. ** Example NVME speed tests with a Samsung 980 drive {{{#!bash root@jammy-malibu:~# dd if=/dev/nvme0n1 of=/dev/null bs=1M count=10k iflag=direct 10240+0 records in 10240+0 records out 10737418240 bytes (11 GB, 10 GiB) copied, 5.80117 s, 1.9 GB/s }}} == LED Programming A front panel status LED has been provided to indicate the status of the unit. This LED is bidirectional and can be programmed for red or green color. When power is applied, the LED will be a solid green. The LED will present a green heartbeat pattern is shown once the board is booted into Linux. [[Image(LED.JPG,500px)]] To disable the heartbeat LED: {{{ root@jammy-malibu:~# echo none > /sys/class/leds/green\:heartbeat/trigger #disable default green heartbeat root@jammy-malibu:~# echo 255 > /sys/class/leds/red\:status/brightness #set LED to solid RED }}} To see more Linux LED examples, see here: [wiki:linux/led] == Thermal Considerations [[Image(fan.JPG,100px)]] The GW3089 uses the industrial temperature quad core Marvell CN9130 processor rated at 2.2GHz. The Tjunction rating for the processor is -40C to +105C. The GW3089 enclosure contains a built in CUI fan (model CUI CFM-4020BF-095-342-22) to keep the unit cool and provide airflow to the processor. When the unit first boots, the fan will turn on to full speed and then once Linux starts it will be under thermal control based on the processor's AP core temperature. The fan runs at specific set points. The trip points are set at 50C, 60C and 80C (as shown in the device tree [https://github.com/Gateworks/linux-malibu/blob/v6.1-malibu/arch/arm64/boot/dts/marvell/cn9130-malibu-gw8901.dts#L413 here]). Note also the processor will throttle down if the fan isn't able to achieve proper cooling with the fan. The PWM values for the four default set points are as follows: * Fan Off < 50C * Fan On 40% PWM = 50C to 60C * Fan On 67% PWM = 60C to 80C * Fan On 100% PWM > 80C These can be adjusted through the device tree if required. ** Fan specifications: * Operating Voltage: 5VDC * Typical Power Consumption: 1.45W * Typical RPM: 9500 RPM, Min 8550, Max 10450 * Typical CFM: 11.88 * Typical Noise: 34.2 dBA * MTBF: Typ. 70K Hours @ +40C * Operating Temp: -10C to +70C * Dual Ball Bearing * Auto Restart Protection * Polarity Protection * Soft Start * Tachometer Signal * PWM Control * Safety Approvals: UL, cUL, TUV, CE * RoHS ** Temperature Monitoring The CPU and 10GbE Phy have passive heatsinks to allow better cooling on these devices. Typical CPU temperature rise is around 8 degrees over ambient when running a moderate load. When installing M.2 cards in the GW3089 make sure to take cooling into consideration. Most NVME and AI accelerators recommend some type of heatsink. The narrow width of the GW3089 enclosure will only allow an 8 to 9mm heatsink (depending on height of devices on the M.2 card). When installing heatsinks make sure to align the fins to maximize cooling with the air flowing from the front to rear of the enclosure. The GW8901 uses standard Linux cooling-maps, thermal-zones and the pwm-fan driver. There are several temperature sensors on the board, identified as 'thermal_zones'. These are shown in Linux under /sys/class/thermal: {{{ root@jammy-malibu:~# ls -la /sys/class/thermal/ total 0 drwxr-xr-x 2 root root 0 Jun 27 18:28 . drwxr-xr-x 62 root root 0 Jun 27 18:28 .. lrwxrwxrwx 1 root root 0 Jun 27 18:28 cooling_device0 -> ../../devices/virtual/thermal/cooling_device0 lrwxrwxrwx 1 root root 0 Jun 27 18:28 cooling_device1 -> ../../devices/virtual/thermal/cooling_device1 lrwxrwxrwx 1 root root 0 Jun 27 18:31 cooling_device2 -> ../../devices/virtual/thermal/cooling_device2 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone0 -> ../../devices/virtual/thermal/thermal_zone0 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone1 -> ../../devices/virtual/thermal/thermal_zone1 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone2 -> ../../devices/virtual/thermal/thermal_zone2 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone3 -> ../../devices/virtual/thermal/thermal_zone3 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone4 -> ../../devices/virtual/thermal/thermal_zone4 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone5 -> ../../devices/virtual/thermal/thermal_zone5 }}} An example temperature for thermal_zone0 would be 60738, or 60738/1000=60.738 degrees Celsius: {{{ root@jammy-malibu:~# cat /sys/class/thermal/thermal_zone0/temp 60738 }}} The zones are labeled below. The AP stands for application processor, or the main CPU, with a sensor for each core of the quad core CPU. The CP0 stands for 'co-processor'. {{{ root@jammy-malibu:~# cat /sys/class/thermal/thermal_zone*/type ap-thermal-ic ap-thermal-cpu0 ap-thermal-cpu1 ap-thermal-cpu2 ap-thermal-cpu3 cp0-thermal-ic }}} ** Fan tachometer / tach rpm: The fan tachometer can be monitored using the following command: {{{ root@jammy-malibu:/sys/class/hwmon/hwmon0# cat fan1_input 9510 }}} ** Gateworks System Controller The Gateworks System Controller manages things like the real time clock, voltage rails, fan PWM, etc. and more information can be found here: [wiki:gsc] == Software The GW3089 is part of the Gateworks Malibu family of SBCs.

It allows for remote access to your GBlades. See the following link for instructions on using and installing: [https://meshcentral.com/info/ Link] For a quick trial without installing the host software, you can create a free "Public Server Account" on the !MeshCental website and then add clients to this account. To install the client agent on a GBlade, click the "Agent" link under my devices tab, select "Linux/BSD" operating system and then copy the command line code from the popup box and run it from your command line on the GBlade. After completion, the GBlade will show up as a device in the !MeshCentral dashboard. Example command line code (note keys have been edited out): {{{ (wget "https://meshcentral.com/meshagents?script=1" -O ./meshinstall.sh || wget "https://meshcentral.com/meshagents?script=1" --no-proxy -O ./meshinstall.sh) && chmod 755 ./meshinstall.sh && sudo -E ./meshinstall.sh https://meshcentral.com 'xxxxxxxxxxxxx' || ./meshinstall.sh https://meshcentral.com 'xxxxxxxxxxxxxx' }}} [[Image(meshcentralagent.png,500px)]] === TPM / Crypto See [wiki:tpm] === JTAG Programming & Firmware/OS Update The GW3089 incorporates onboard a USB to JTAG FTDI chip to allow JTAG programming of the unit without the requirement for a separate JTAG dongle (GW16099) which is typically used on other Gateworks SBCs. At this time, the GW3089 JTAG software is under development so for initial programming please see the following link on updating from a TFTP server: [wiki:malibu/firmware#UpdateFirmwareviaSerialConsoleandEthernetfromBootloader]. Check back for future JTAG software releases which will be posted here. Note that loading software over JTAG can take a significant amount of time so we recommend only using JTAG to load the bootloader and then using a TFTP server to load the Ubuntu image which can be quite large. == Enclosure The GW3089 anodized enclosure uses the following screws for securing the board, fan and frontplate. * Frontplate = Torx T8 Head, M3 x 8mm * Fan = Torx T10 Head, M3 x 25mm * Board standoffs = Hex 1.5mm Head M2.5 x 5mm === 1U Rack Frontplate [[Image(gw3090rack.jpg,500px)]] A standard 1U rack frontplate is available to install QTY 10 GBlade servers in a rack mount scenario. The 1U plate part number is GW3090. Contact sales@gateworks.com to purchase. See the following instructions for installing individual Gblades into the 1U frontplate: 1. Remove the four frontplate screws using a T8 Torx driver. 2. Remove the LED cable from the frontplate. Note the LED has a rear socket and a front lens. Gently pull the rear socket to separate from the front lens. Note there is a small rubber washer on the front lens which should be removed when installing in the thicker metal 1U frontplate. 3. Move the unit to behind the 1U plate in the location that it will be installed and re-attach the LED cable by inserting the LED lens from the front side and pushing the socket onto it from the rear. 4. Attach the unit to the 1U frontplate using the four Torx screws that held the original frontplate. == Wireless & Modems Wireless & modems were not intended for this ethernet connected blade server.
