High Performance Diskless Linux At AX-Div, LLNL

Posted by timothy on from the four-letter-acronym dept.

Lee Busby writes "As a co-author, I am biased, but I think that our recent paper describing a diskless Linux deployment at Lawrence Livermore National Lab (PDF)may be of general interest. It's a little different than most diskless systems -- simpler, and designed to be high performance."

    the more they stay the same. This doesn't seem too much different from the 'dumb' terminal connected to the corporate mainframe that is still in use today. Except that it is running Linux, a much superios OS to IBM's MVS or z/OS.

  2. Re:iSCSI? by 4of12 · · Score: 2, Insightful

    Sharing common resources is great, and NFS performance is increased if they're all mounted read-only on the clients.

    Keeping some protection and partition of /home/me over iSCSI to a single workstation seems like a good idea to me. Given all the concerns of classified processing, it's not like you and some other workstation are going to be routinely part of a parallel cluster where multiple clients need write access to the same filesystem.

    Then, each client would only need a writable /etc for system configuration and /var for log files over iSCSI.

    I'm not familiar enough to know, but if the traffic is read only, can't the same /usr/bin be exported to multiple clients via iSCSI?
