Correct, it's a nontrivial upgrade, expect a lot of labor and materials (new covers, etc.).

The 170 will work with 2, 4, 8, and 17 GB disks. Essentially any of the double byte (68 pin) style of drives (7200 RPM) as well as the 10K RPM 8 and 17GB units. Heck I just bet it would work with the 10K RPM 35GB Units but that would be unsupported now wouldn't it?? Depending on how far back your OS is you MIGHT run into a problem with the 17GB units but I doubt it. As to how to use them, if you have only two you likely have them running naked (i.e. no disk protection). I would strongly recommend you add a pair of 8GB units and then crank up mirroring. This would move you from 8 GB unprotected to 12 GB mirrored and doesn't care about which controller you have. Of course you can (at your own risk and peril) run the new 8GB units unprotected too and in that case end up with 24 GB of disk. You don't say which disk controller you have but if you have only two drives I suspect strongly that you have only the base controller, not the 2740, 41, 26 or 48 any of which would get you RAID capability. In that case you'd need to add only 4GB disks anyway to get to the minimum RAID set size of 4 units. Hope this helps! - Larry (aka DrFranken) You can Raul A.
