Features
The IBM® Netfinity® EXP300 is a compact unit that provides high-capacity, small computer system interface (SCSI) disk storage. It supports up to 14 Ultra160 SCSI drives on a single or dual logical bus. It delivers fast, high-volume data transfer, retrieval, and storage functions across multiple drives, to multiple hosts. The expansion enclosure is designed for continuous, reliable service; the modular, redundant disk drives, power supplies with built-in fans, and environmental services monitor (ESM) boards use hot-swap technology for easy replacement without turning off the expansion unit.
The expansion unit supports Ultra160 SCSI for the host and drive interfaces and it is designed for easy installation and integration into a variety of system environments.
The following table summarizes the features of the expansion unit. For a list of the operating specifications, such as weight, height, and heat output, see “Operating specifications” on page 5.
