Database Copy LUN Size - 30.Jun.2014 3:32:50 AM

Hi,

Quick question about database copies and the storage requirements.

I understand that for a DB copy, each MBX server has to have the same drive letters for the relevant drives/LUNS, but what about size?

Do the drives have to be the same size?

The reason for asking is that we already have two MBX servers and all our DBs have copies on drives that are exactly the same size. We are looking to replace the underlying hardware one by one (i.e. introduce a new MBX server to the DAG and copies, then eject the old one, rinse and repeat), and are hoping to increase the capacity of the drives at the same time.

Thanks.

In the above mentioned case, you donít need to keep the drives to be the same size. During storage migration the drive size can be different but remember that while production your drives size should be the same. If you will keep them different then the copies will not work when one of them fills up.
