S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology)
Attributes
The Adtron Diskpak I35MB incorporates an array of S.M.A.R.T. attributes and
capabilities that provide significant amounts of information relating to the life
history of the hard disk drive (HDD). S.M.A.R.T. is a monitoring system for
computer (HDDs) to detect and report on various indicators of reliability, with the
intent of anticipating failures. The user or system administrator can send a query
using S.M.A.R.T. technology to retrieve requested data. This provides time to
anticipate drive failure and to take preventive action — such as copying the data to a
replacement device.
The I35MB incoporates:
•
Operational Attribute Data
•
User and manufacturing log pages
•
Error Log pages
•
Self-test
Using RAID-1 mirroring techniques, the I35MB duplicates data using two disk
interfaces that are referred to as Bank 0 and Bank 1. The user can determine the
status of the data mirror as a whole, as well as each bank individually, using
industry- standard S.M.A.R.T commands. The S.M.A.R.T. Attributes that specifically
apply to the I35MB are summarized below, and a more detailed description appears
in Table 3.
Contact Adtron for more S.M.A.R.T. details.
