Abstract
In a storage subsystem adopting HDD and PCIe-SSD as storage media, as a method for preventing the complication of having to select a removal method while considering the drive type inserted to the drive slot since the method for removing the HDD differs from the method for removing the PCIe-SSD according to the prior art, the present invention provides an LED for displaying whether it is possible to remove the HDD or the PCIe-SSD inserted to the slot of a drive enclosure, wherein when an HDD is inserted in the drive slot, the LED displays that removal of the HDD is enabled when power supply to the HDD is stopped, and when PCIe-SSD is inserted to the drive slot, the LED displays that removal of the SSD is enabled when Downstream Port Containment (DPC) is triggered in the downstream port of the PCIe switch to which the SSD is connected.
