  9. Mass Storage Improvements Geoscience Copy 1 Seismology Copy 2 ADIC 700 slots Cisco 2 LTO2 Drives storage 1 LTO2 drive Backup Gig Ethernet Gig Ethernet STK 9840 Silo 6000 slots 120TB Apple Xserve FC-AL 2GB RAID Sun E4500 10 9840 Drives Sun V440 A1000 RAID

  10. Backup • Current • 40 Suns via Legato on ADIC and Overland LTO2 tape • 50 Macs via Retrospect on Mass Store Currently 3.3TB • Legato license extended to 128 LTO2 tapes = 25TB • Macs running pre OS X via Retrospect on Mass Store • Macs running OS X via Retrospect on Mass Store • No PCs running Linux (except for special cases) • No PCs running Windows (except for special cases)

  12. Directions for FY 2004-2005

  13. Current LDEO Email Configuration February 2004 Cisco 100Mbit 100Mbit Lamont 2 X CPU 2 X PS 2 X root Miles SMTP & IMAP Ultra160 SCSI LDEO email FTP LDEO Home dirs 350GB SCSI RAID 5 with hot spare

  14. Future LDEO Email - Home Directory Configuration I SMTP Server 1000Mbit/sec 1000Mbit/sec 2 X CPU 2 X PS 2 X root BlueArc NAS 3-7 TB SMTP Server 2 X CPU 2 X PS 2 X root 1000Mbit/sec Cisco IMAP Server 2 X CPU 2 X PS 2 X root IMAP Server Backup NAS SATA 2 X CPU 2 X PS 2 X root

  15. Future LDEO Email - Home Directory Configuration II SMTP Server 1000Mbit/sec 1000Mbit/sec Apple Xserve 2 X CPU 2 X CPU 2 X PS 2 X root SMTP Server 2 X CPU 2 X PS 2 X root IMAP Server Cisco Apple Xserve RAID 3 TB - 7 TB 2 X CPU 2 X PS 2 X root 1000Mbit/sec IMAP Server Backup NAS SATA 2 X CPU 2 X PS 2 X root

  16. Future Admin server Cisco 55 Win2K PCs 1000Mbit 2 X CPU 2 X PS 2 X root 4 X CPU 2 X PS 2 X root 100Mbit switch 1000Mbit Sun V440 PDC & SMB Sun U250 PDC & SMB Sun A1000 RAID 84 GB Sun A1000 RAID 168 GB Tape Robot BU Tape Robot BU

  17. 1 – 3 TB NAS SATA Future LDEO Webserver HTTP Server 1000Mbit/sec 1000Mbit/sec 2 X CPU 2 X PS 2 X root HTTP Server 2 X CPU 2 X PS 2 X root Web Mail Cisco 2 X CPU 2 X PS 2 X root Database Server 2 X CPU 2 X PS 2 X root

  18. Backup • Issues • 350 PCs & Macs X ~40GB = 14TB X 2+ cycles = really large bit bucket !! • Moblie machines • Large workgroup filesytems & databases (Arko, Floyd, Stark, etc) • Legato license extended to 128 LTO2 tapes = 25TB • Need to add LTO2 tape drive to ADIC • Goal • Macs running pre OS X via Retrospect on Mass Store • Macs running OS X via Legato on ADIC • PCs running Linux via Legato on ADIC • PCs running Windows via Legato On ADIC

  19. Decisions/Policies

  20. Backup • User policy/education to limit desktop backup volume • Segregate application & data (probably not possible) • Backup folder • Push or Pull • Policy and/or hardware for large workgroup filesystems • Don’t offer backup for RAID systems • Coordinate purchase additional disk at time of purchase • Negotiate backup schedule

  21. BlueArc NAS Filer ‘Best in Breed’ Very fast Very Reliable Snapshot block level backup NFS + CIFS file locking Very expensive $10.71/GB Expensive to upgrade Expensive to maintain $8,000/yr NoName NAS Generic Win/Tel or Linux Fast Reliable File based backup NFS SMB via Samba Cost effective $3.57/GB Less expensive upgrades Maintanence 1- 2K/yr
