DELL CERC ATA100/4ch RAID Controller

Windows device driver information for DELL CERC ATA100/4ch RAID Controller

The DELL CERC ATA100/4ch RAID Controller is a PCI controller that is ATA based. It provides users with a high performance yet low cost alternative to the SCSI (small computer system interface) RAID (redundant array of independent disks). This intelligent PCI (peripheral component interconnect) host bus adapter has a 100 MB per second throughput for every 4 ATA channels. One of the main advantages of using this device is that users can benefit from RAID benefits at a lower cost. Further, by utilizing any available RAID levels (with the exception of RAID 0) data loss caused by a single drive’s failure can be eliminated (RAID 5 or RAID 1 as an example) or 2 drives (RAID 10 in the event that the drives that failed are located in different sets of RAID 1). Data storage via the DELL CERC ATA100/4ch RAID Controller (with the exception of RAID 0) can endure the loss of a single drive without having to force server downtime. As a result, administrators are able to schedule downtime for repair operations on non-peak hours.

The device’s hot spare function also delivers improved fault tolerance since administrators are able to assign 1 or more drives to instantly swap a drive that has failed. With the use of this device’s driver, administrators are also enabled to repair a failed disk array under a CERC card’s helm via bringing the server down, swapping the drive and rebooting the server instead of having to reload from backup media or from tape. The DELL CERC ATA100/4ch RAID Controller is then capable of rebuilding the disk array and restoring it in hours. This CERC card uses its dedicated microprocessor for performing RAID functions. Since it can offload RAID operations to its microprocessor, it allows the main CPU server to focus on other operations which greatly help in maximizing the overall performance of the system.
