I will be using the Adaptec 7 series raid card with 6 internal ports (24 drives) and 1 external expansion port.
The one item I do not see discussed in the thread above is future expansion capabilities. I would like to use SAS expanders to other identical cases with more drives as my needs increase for storage thereby reducing costs (hopefully) in not having to buy multiple RAID cards and having all storage seen as a single server.
The goal would be to have all my client PC's (all Windows) mount to a single server \\server1 and then just see multiple logical drives as the storage continues to grow. Right now I am thinking of using RAID-6 across 12 drives - so each case would have 2 logical drives.
Can someone provide details on what would be needed in a second, third, fourth, etc box (identical case and drives as the first machine) in order to continue to grow the system over time? Motherboard, processor, ram, expander card, etc...
