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 unit 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.
After you review the introductory information provided in this chapter, refer to
"Chapter 2. Installing the expansion unit," on page 9 to begin the installation process.
