Hi All,
Wondering if anyone here would care to comment on SANs and/or NASs. Have you used any particular brand, general configuration ideas, price ranges?
I, been managing an environment in which a dozen servers running Linux, have their own large scsi drive farm of their own, either on raid or individually. Due to different circumstances, these drives need to be cross mounted throughout the network.
This became a problem when one of the servers would go down; it pretty much brought other servers down. The way I fixed that problem was by managing NFS on "let-me-know-what-you-need" bases and I would mount it and then remove the mount when not needed anymore.
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 capacity.
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.
Rafael.
