Dell PERC 3/J2 Evaluation Board

Windows device driver information for Dell PERC 3/J2 Evaluation Board

The Dell PERC 3/J2 Evaluation Board is used in conjunction with the Dell PERC 3 (PowerEdge Expandable RAID Controller) PCI card. PERC 3 in an intelligent and high performance PCI to SCSI host adapter device complete with RAID control functionalities. This device delivers system stability and disk subsystem management that is fully fault tolerant. It is a perfect solution for Dell’s enterprise, departmental, and workgroup systems’ internal storage. The PERC 3/QC LVD delivers 4 SCSI channels, while the PERC 3/DCL and PERC 3/DC PCI RAID device delivers 2 SCSI channels. Lastly, the PERC 3/SC LVD card device delivers on only 1 SCSI channel. With the LVD (low voltage differential), users can utilize cables that are 25m long and throughput for every SCSI channel may be as high as 160 megabits per second. The PERC 3 has support for both a SCSI bus that is single ended and an LVD SCSI bus.

The PERC 3/DC and PERC 3/QC has support for a SDRAM of 128 MB. The PERC 3/DCL has support for an SDRAM of 64 MB, while the PERC 3/SC only has support for an SDRAM of 32 MB. 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 3 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. It is highly recommended you run a free registry scan for and Dell PERC 3/J2 Evaluation Board errors before installing any driver updates.
