  Radio FileserverStorCase TB Storage

X-Ray Crystallography Facility (XRF) in April 2005 has added a one tera byte (1 TB) storage system to accommodate the increasing amounts of x-ray diffraction data collected both at synchrotron and home source. The system has a nine (9) bay Data Silo StorCase DS400 chasis with nine (9) Seagate UltraSCSI drives. The storage system is controlled by a Ubuntu Linux machine (radio.sb.fsu.edu) running a software RAID control with logical volume size of 150 GB per group. The storage disk is mounted to processing Linux machines (raccoon and neptune.sb.fsu.edu) via a dedicated 1 gigabit ethernet switch. More details about the system is given below:
  • Current Operating System: Ubuntu 5.04 Linux Kernel v. 2.6.10-4-386
  • Software RAID control | RAID Level: 5 | Number of Disks: 9 | Spare Disks: 0 | Chunk size: 32 kB
  • RAID controller on radio.sb.fsu.edu (128.186.103.112)
  • Radio.sb.fsu.edu | Single 3.00 GHz Intel Pentium 4 Processor | 512 MB memory
  • Linksys SD2008 8-port 1 gigabit switch
  • One HP StorageWorks Ultrium 215 tapedrive with LTO Ultrium-1 tapemedia
  • One FireWire400 (IEEE 1394) adapter
  • One HiSpeed USB2.0 adapter
  • One Intel Pro 1 Gbit ethernet adapter
