Lenovo ThinkSystem 530-4i - storage controller (RAID) - SATA / SAS 12Gb/s - PCIe 3.0 x8

Along with an extensive list of enterprise RAID capabilities, the RAID 530 Series adapters offer advanced drive diagnostic technologies. In the event of a physical drive failure, the drive is placed in a shielded state and the controller starts drive diagnostics to determine if the drive is indeed failed or can be restored. This saves time, money and server downtime associated with transient drive failures and unnecessary drive replacement.
