The server of the Cash Registers Company is using an Adaptec Raid 5 controller and the existing storage was gradually running out of space. Our technicians had to run S.M.A.R.T (Self-Monitoring and Reporting Technology) diagnostic, which scans through the hard drive and looks for an imminent mechanical failure or a recent failure. In that way, we were sure that the HDDs are in good condition. Based on that, we decided to add an extra HDD to the existing array in order to expand the volume of the storage space.
The Adapter Raid card allows dynamic and immediate array expansion, so the array does not need to be rebuilt from scratch. This is a great technology that can be operated with easily and safely.
