Presentation Transcript

  1. 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)

  4. Reality Check • AIA/HMI combined data volume 2 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 ethernet 50 – 100 MB/s • 4 – 8 channels per server, 5 servers (today) • SAIT-1 native transfer rate 25 – 30 MB/s • 10 SAIT-1 drives per library, 2 libraries (today)
