Jdat production hardware

JDAT Production Hardware

  • Compute nodes (< 100)

    • 2-, 4-, 8-multicore processors per node

    • 16+ GB per processor

    • 64-bit linux

  • Database nodes (< 5)

    • Oracle cluster

    • 5 TB shared database volume

  • I/O nodes (< 10)

    • High-availability NFS server cluster

    • Multiple fibre channel connections to non-shared disks and tape drives

    • Multiple gigabit ethernet connections to compute nodes

  • RAID disk storage

    • 400 TB initially

    • 100 TB annual increment

    • SATA drives (500 GB today)

  • Tape Archive

    • Two PB-sized tape libraries initially

    • ½ PB per library annual increment

    • SAIT (500 GB, 30 MB/s today) or LTO (400 GB, 80 MB/s today)

Reality check

Reality Check

  • AIA/HMI combined data volume2 PB/yr = 60 MB/s

    • read + write x 2

    • quick look + final x 2

    • one reprocessing x 2

    • 25% duty cycle x 4

      2 GB/s (disk)

      1/2 GB/s (tape)

  • NFS over gigabit ethernet50 – 100 MB/s

    • 4 – 8 channels per server, 5 servers (today)

  • SAIT-1 native transfer rate25 – 30 MB/s

    • 10 SAIT-1 drives per library, 2 libraries (today)
