This metadata is written to the drives by the RAID controller’s firmware when the array is created. This information is located in the first or last sectors of each drive and is known as metadata. The RAID configuration data is stored on the drives that make up the array. Unfortunately, the varying methods used to store RAID configuration data make it impossible to transfer data between storage systems of different manufacturers without data loss. The second option involves a certain risk of data loss but lets you save a lot of time instead. and the simple one, where you just connect the drives to the new controller and import the external configuration.The difficult one, which requires you to make a backup copy of data, reconfigure the array and recover data from the backup.Whatever happens, there is one question to answer: can you migrate to a new device without losing data?įortunately, there are a few ways of doing that: With the growing amounts of data to process, sooner or later you will have to expand the disk array, but often you cannot do it because of the old controller, and sometimes controllers may just fail. In a modern IT environment, there could be several reasons why system administrators would like to change from one RAID controller to another.
