 diskless Solaris 10 setup? Hi all, I have a set of x86-based systems that I'd like to configure diskless and then serve their filesystems from a single RAID server. One catch is that each system has different hardware and will require different drivers. I'm guessing that I can put the superset of drivers in a (common) root filesystem that's mounted via NFS, but I really don't know where to start setting this up from either the server or client side. Can someone provide any insight? Thanks very much, Dave      |

Our latest exercise demonstrated that the (U320) SCSI drives/subchassis/cabling isn't handling the jiggling very well. Multiple systems had problems booting almost every day and the current RAID system developed enough issues that it'll have to be completely reworked. Lather, rinse, repeat. The thinking is that we can approach this on two fronts - fewer overall disks and fewer physical connections to the remaining disks (SATA or maybe SAS) in a RAID system. Thanks, Dave |

They've shredded servers a friend sent to a trade show packed this way, then refused to replace them as they were "improperly packaged". -- DeeDee, don't press that button! DeeDee! NO! Dee... |

Various manufacturers provide FLASH based drop-in replacements for standard form factor drives. You should be able to get pretty much any standard SCSI capacity in standard SCSI form factor. At which point I'd just hot-glue everything in place and give it a go. The drives are designed for environments where traditional spindles don't last due to environmental factors. -- Andre |
