31 Terabytes of storage?
Isn't Google Great?
If Firewire supports 63 devices ( http://en.wikipedia.org/wiki/IEEE_1394 ) and you got 500 GB external drives ( http://www.zipzoomfly.com/jsp/Produc...uctCode=102653 ) could you build a system with 31 Terabytes of storage? (more with USB) Granted, cost of 31 grand. I would suspect running into problems long before reaching more than a few terabytes. I'd appreciate some comments from folks who have built or seen high capacity storage systems and how they did it. Maybe a link or two? Thanks. Terry |

Terry Good luck looking for that elusive file though ;-) It would probably take Windows an hour to search all drives Scott |

Terry USB2 would probably be a better solution, then you can get 127 devices from each root hub. Since the average PC has say 2 onboard ones, and 5 PCI slots, each of which could have say 3 root hubs on. hamman |

Use SCSI for multi access, multi-write (*BSD/GNULinux=concurrent, not like MS=consecutive, access!) PLUS, you can cluster an unlimited number of towers, and pool all of the resources! Do like GOOGLE.com! 3. USB1.1 and 2 divides the access speed by the number of devices. Super Sloooooow after about 5 devices! |

Super Sloooooow after about 5 devices! Ouch, plus the electricity requirements to run all those devices. |

(more with USB) Granted, cost of 31 grand. Not sure how windows handles drive letters above Z, and with your 63 devices, how would it deal with giving each one a unique letter identifier? From MS: Mounted drives, also known as volume mount points or drive paths, are volumes attached to an empty folder on an NTFS volume. Mounted drives function the same way as any other volume, but are assigned a label or name instead of a drive letter. Mounted drives are robust against system changes that occur when devices are added or removed from a computer. They are not subject to the 26-volume limit imposed by drive letters, so you can use them for access to more than 26 volumes on your computer. So I gather you could name volumes anthing you like using NTFS |

In this case i can see some massive 0+1 Arrays.... just a problem of how to do RAID over firewire.... |

(more with USB) Granted, cost of 31 grand. I recall hearing that folks trying to carefully implement USB discovered all sorts of problems as the number of devices got large, and not even close to the maximum number spelled out in the standard. Apparently sorts of companies had never tried their products with a few dozen or more of them hanging on the bus at once. So I think that well before you run out of drive letters, or thousand dollar bills to buy the drives with, you will find other things to worry about. General rule: If you didn't test that particular configuration, it is probably broken. |
