to add disks to a raid array - and have the data integrated into it ratehr than have the disk wiped
Kaleidescape’s KSERVER-5000 and KSERVER-1500 use a proprietary RAID-K in their media storage units. RAID-K is similar to RAID 4 in using double parity, but RAID-K also uses another, proprietary method of maintaining fault tolerance.[clarification needed] The system is easily modified, as users can expand the array simply by inserting additional hard disks. Additionally, if any hard disk is inserted with data already on it, the data is automatically added to the array instead of deleting the data, as many other RAID methods would require.
i know we’ve already been over why this would be impractical for drobo and the difficulties in implementing it, so im not even going to suggest it as a feature, but it sure would make peoples lives easier if it could be done this easily!
