Product Description
The IBM 53P4802 is a SCSI3 PCI RAID controller card, identified by its 2778 chipset, designed to enhance storage capabilities in IBM server environments. It utilizes the PCI interface for broad compatibility and supports SCSI-3 Ultra160 technology, offering improved performance over older SCSI standards. This controller primarily focuses on providing basic RAID functionality, supporting RAID 0 (striping) for performance gains and RAID 1 (mirroring) for data redundancy, ensuring that critical data remains accessible even in the event of a drive failure. The card features dual 68-pin VHDCI connectors, one for internal drive connections and one for external storage expansion. This dual-port configuration allows for flexible system design, enabling users to connect drives within the server chassis or to external storage enclosures. The SCSI-3 Ultra160 interface provides a data transfer rate of up to 80 MB/s, which is suitable for many business applications requiring reliable data access and basic performance improvements. While the IBM 53P4802 does not typically come with onboard cache memory and supports only basic RAID levels, it serves as a cost-effective solution for organizations needing fundamental data protection and storage management. Its IBM chipset ensures compatibility and reliability within IBM server ecosystems. This controller is a practical choice for entry-level servers or workstations where advanced RAID features are not a primary requirement, but basic data integrity and performance are still important.
