The DELL PERC 4/QCx RAID Controller is an intelligent, high performance PCI to SCSI host adapter that has RAID control functions. Almost all operating systems do not write and read data directly from disks, rather, they send write and read commands to a controller. A RAID controller such as the DELL PERC 4/QCx is able to span the disks’ boundaries in order to produce bigger storage space by utilizing the capacity of more than a single disk. This device likewise carries out other tasks like initializing disks and initiating rebuilds among others. In order to accomplish its tasks, this RAID controller needs special software known as a driver so that it can implement its functions in the host computer system efficiently. Every channel on the PERC 4/QCx has support for 320 MB per second per channel SCSI data transfer rates and each channel can also support a maximum of 15 devices.
Unless you update your drivers regularly you may face hardware performance issues.
To check your drivers you should manually verify every device on your system for driver updates
This RAID controller has hot spares which serve a backup in the event that a disk fails. This controller is capable of rebuilding data from an array disk that failed if the disk is a component of the redundant virtual disk. It also has a virtual disk expansion feature which allows users to expand a virtual disk’s capacity even if it is online via adding more disks. This function is likewise known as the OCLE or online capacity expansion. The DELL PERC 4/QCx RAID Controller allows the modification of RAID levels after the creation of a virtual disk and moving virtual disks and arrays from one controller to the other controller. In addition, this RAID controller has cluster support and a check consistency feature that can verify the integrity of the redundant data of virtual disks. It is highly recommended you run a free registry scan for and DELL PERC 4/QCx RAID Controller errors before installing any driver updates.
