The model and capacity of a replacement drive does not match the original drives in the server.
This information is not Operating System specific
The following information applies to replacement drives shipped from Adaptec to replace a disk failure. The use of third party drives that are not specifically intended for use with the server is unsupported and will void any remaining warranty.
Overland Storage may qualify more than one drive manufacturer for use in a particular Snapserver model. Although different manufactures may advertise drives of the same capacity in Gigabytes, the actual capacity between them may vary to some extent. The drives may have a capacity difference of as much as 2% or slightly more. To ensure drives of different manufacturers can be interchanged in an existing RAID configuration, the data partition size of the drives used for a Snap server must be regulated
In cases where a Manufacture EOL's (End of Life) a certain capacity drive Overland Storage may ship a replacement of larger capacity. This will not effect integrity or performance of your RAID.
