Chapter 1 Introduction 1-11
Reliability • Mechanical for easier insertion and extraction and better locking mechanisms for
disks and other FRUs
• Blind mate connectors to avoid bent pins on FRU insertion
Availability • Enhanced temperature monitoring to shut down the system only when temperature
thresholds are exceeded
• Automated power cooling unit (PCU) adjusts fan speed based on the temperature
monitoring
• Improved battery recharge control to avoid missing battery recharge if a Sun StorEdge
6020 array was shut down during battery recharge cycles
• Automated and online firmware upgrade and downgrades
• Hardware integrated device electronics (IDE) interface to introduce cache saving
procedures without adding battery cost as higher density enclosures are developed
Fault detection,
fault isolation, and
failure fencing • Support for parity on RISC RAM hardware
• Loop card with standard SSC100 management processor and VSC055 serial backplane
controller provides better enclosure management
• Faster and modular loop card serial communication protocol
• Failure fencing (fault containment) in case of hardware failures
• Automatic hardware bypass of the faulty drive should a drive cause loop disruptions
• Hardware support that creates a diagnostics loop of disks for performing background
tests
• Temperature sensors for continuous threshold based temperature monitoring. The
temperature sensors are located close to heat spots to provide accurate temperature
measurements
• Fibre Channel ECHO ELS support, which allows for both external echo tests (invoked
from the Sun StorEdge 6020 array) and passive echo tests (invoked from the Fibre
Channel switch)
• External and internal loopback test support to test front-end controller and back-end
Fibre Channel ports
• Fibre Channel link status counters for threshold-based analysis of link error statistics
