  1. A Novel Solution to Large Volume Data Storage Nicholas Tulley City Hospital, Birmingham Department of Physics & Nuclear Medicine

  2. The Problem Amount of data increased significantly Gated SPECT hearts with AC (~150MB) Optical disks now inadequate (2 GB each) Archive on this media very expensive Instant data retrieval requested by clinician

  3. Terminology Online Data available instantly Offline Data needs to be retrieved Backup COPY the data Archive MOVE the data RAID Reliable data store – This is NOT A BACKUP (unless it is a COPY)

  4. Archive Solutions • DAT tape • Additional local disks • Local RAID storage • External hard drive

  5. Archive Solutions • DAT tape • Additional local disks • Local RAID storage • External hard drive OR • Use hospital networked-storage • Built-in backup facility (IT staff)

  6. Network Storage Very high capacity (TB not GB) Easily expanded High Availability – High Security Some technical skill required Backup done by hospital IT Dept. Cost – negotiable with IT !

  8. Services for Unix (SFU) Microsoft’s answer to the Unix / Linux threat Program available as free download Installation fairly straightforward Some simple configuration Allows a Windows PC / Server to interact with a Unix environment

  9. Services for Unix (SFU) Microsoft’s answer to the Unix / Linux threat Program available as free download Installation fairly straightforward Some simple configuration Allows a Windows PC / Server to interact with a Unix environment

  10. SFU Advantages • Not much UNIX knowledge needed • (SAMBA is the UNIX alternative) • Windows familiarity • IT Dept has Windows SAN Expertise • Easy Windows drag’n’drop filing • Free • (Custom) install is quite easy…

  11. Custom Install of SFU

  12. Custom Install of SFU:Local User Name Mapping

  13. Custom Install of SFU:Local User Name Mapping Two files needed from Unix: \etc\passwd \etc\group Create a folder on c: for them. e.g. c:\SFUusers and copy them

  14. Explorer View of Windows folders

  15. Sharing a WindowsFolder for Unix

  16. Sharing a Folder for Unix

  17. Conclusion • Local or Remote large disk drives can be added for management under (the more familiar) Windows environment. • Using remote (IT serviced) data storage solves the headache of reliable data backup.

  23. Half Duplex Problem On ‘LX’ (Linux) System Old Configuration OK Very slow after upgrade to Switched Network Was working at ‘half-duplex’ i.e. only in one direction at a time Simple ‘fix’ to make Full Duplex
