UFO Server

System

  • Host name: ufosrv1.ka.fzk.de
  • Interfaces: eth0 (10 GBit), eth1 (upper-right socket)
    • eth0: dhcp
    • eth1: 141.52.111.135/22
    • Gateway: 141.52.111.208 (via dhcp)
    • Name server: 141.52.111.248 (via dhcp)
  • Running services
    • SSH on ports 22 and 24
    • NX server over SSH
    • VirtualGL (OpenGL forwarding)

Hardware

  • Display connected to integrated video card (Matrox G200)
  • 2 x Xeon X5650 / Intel X58 / 96 GB DDR3
  • System drives: 2 x Hitachi 2TB SATA2
  • Areca ARC-1880 Raid Controller (x16 slot)
    • 16 x 2 TB Hitachi HUA722020ALA330 in external Areca Enclosure
    • 4 x 256 Crucial RealSSD C300
  • External PCIe 2.0 x16 (x16 slot)
    • External GPU box from One Stop Systems
    • 4 x NVIDIA GeForce? GTX580
  • 2 x NVIDIA GeForce? GTX580 (x16 slots)
  • Intel 82598EB 10GBit Ethernet (x4 slot)
  • Silicon Software CameraLink? FrameGrabber? MicroEnable? IV Full (PCIe 1.0 x4 slot)
  • Free slots
    • PCI express: x4 and x1
    • Storage: 2 x SSD in the main server case

Areca Raid Configuration

  • A single Areca-1880 controller handles both external storage box with SATA hard drives and internal SSD cache. Only a pair of system hard drives are connected to the SATA controller integrated in the motherboard.
  • 16 x Hitachi 2TB SATA hard drives in the external enclosure are organized as Raid-6
  • 4 x Crucial SSD C300 in the server case are organized as Raid-0

Partitioning

  • Two system hard-drives are connected to internal SATA controller and mirrored as Raid-1 using Linux Software Raid.
    • Devices: /dev/sda, /dev/sdb
    • Partitions: /boot (2GB ext2), / (256GB ext4), /home (ext4)
  • The RAID is split into the 2 partitions (GPT partition table): the fast and normal.
    • Device: /dev/sdc
    • The fast partition will be used to stream the data from the camera and should be able to stand throughput of 850 MB/s. The data should be moved out as soon as possible. Only a single application is allowed to write to the disk.
      • Size: first 6TB of disk array
      • File system: non-journaled ext4
      • Mount point: /mnt/fast
    • Standard partition is for short term data storage (before offloading to LSDF)
      • Size: 22 TB
      • File system: ext4
      • Mount point: /mnt/raid
  • The SSD cache
    • Device: /dev/sdd
    • Size: 1 TB
    • File system: ext4
    • Mount point: /mnt/ssd
  • Partition table (/dev/sda & /dev/sdc)
