1 Introduction
Welcome
Congratulations on the purchase of your new ST8000 Disk Expansion Unit (DEU). The DEU provides a superior fault-tolerant network storage solution in a subsystem-based SAF-TE compliant RAID enclosure.
he SAF-TE compliant interface provides a standard, non-proprietary means for the RAID subsystem to automatically integrate with peripheral packaging that supports status signals, hot swapping drives and enclosure monitoring. Combined with the enterprise- wide RAID management software, additional levels of fault tolerance can be maintained.
he DEU is an eight drive enclosure designed to support a host system-based architecture. The architecture supports Ultra Wide SCSI (Fast-20).
Features
he following are major features of the DEU disk array subsystem:
RAID Levels — Supports RAID levels 0, 1, 3, 5, 10 (1 + 0), 30, and 50.
Configuration — Deskside tower-based system and rack-mount system (fits into a standard IAE 19-inch rack assembly). Dual-Bus or Single-Bus configuration modules provide for an “easy” PCB plug-in changeable bus configuration.
Drive Support — Up to eight 3.5-inch, half-height form factor, hot swappable drives that use SCA-II technology. Disk drives featured include high performance 7,200 and 10,000 RPM Ultra SCSI hard
Tdisks.
Scalable Capacities — Drive capacities are expandable and even further expansion through daisy-chaining of multiple cabinets.
