Take a look at the IBM D4300 SAN. It is FibreChannel Drives and can
take multiple drive cabinets to get you to 4 TB easy (max capacity is 16
TB). FibreChannel is not cheap. IBM does have the D4300 on sale this
month for around 25000 CAD regular price is 83000 CAD. It comes with 4
fibrecards to put in your servers. It handles linux servers no problem.
~ Most of the IBM resellers in town can tell you more about it.
Hope this helps.

| cross mounted throughout the network.
| This became a problem when one of the servers would go down; it pretty

| Another issue I'm having is that because of the segregation of the data,
| [lot's of it, by the way] sometimes even, across different servers,
| compels users to copy/ftp data around, adding to too much redundancy.
| This causes the misuse of space.
| Right now, I figure I have only about 3TB data in total and about 4TB
| I would like to move towards a large, very large in this case, logical
| volume, a San/Nas solution if you will; except that I'd like to do it as
| inexpensive as possible.
| I'm thinking along the lines of having one or two of my current servers
| host this one or two large volumes, maybe 2TB each volume. Taking into
| consideration some redundancy of course to protect the data from failures.
| These volumes would be external firewire cases perhaps with some sort of
| raid 5, or something similar, and have the rest of the boxes look at
| this one or two volumes for storage. I understand that I would need fast
| Ethernet 1G, fastest ieee possible, fastest ata or sata drives, and the
| fastest server I have in house.
| I thank you in advance for your time. In the mean time, I will continue
| googling my life away.
