HP Insight Management Agents - Manual (Page 77)

NOTE: A value of Unknown indicates that the agents are unable to determine this information
from the physical drive.
•
Current Width displays the current negotiated data transfer width for the physical drive. The
possible values are:
◦ Narrow (8 bits) - The negotiated data transfer width for this drive is narrow (8 data bits).
◦ Wide (16 bits) - The negotiated data transfer width for this drive is wide (16 data bits).
◦ Unknown - The Storage Agents are unable to determine the current negotiated data
transfer width for this drive.
•
Current Speed displays the current negotiated data transfer speed for the physical drive. The
possible values are:
◦ Asynchronous - The current data transfer speed for this drive is asynchronous.
◦ Fast - The current data transfer speed for this drive is 10 million transfers per second.
◦ Ultra - The current data transfer speed for this drive is 20 million transfers per second.
◦ Ultra2 - The current data transfer speed for this drive is 40 million transfers per second.
◦ Ultra3 - The current data transfer speed for this drive is 80 million transfers per second.
◦ Ultra320 - The current data transfer speed for this drive is 160 million transfers per second.
◦ Unknown - The agent is unable to determine the current negotiated data transfer speed
for this drive.
NOTE: If the current data transfer width is Narrow (8 bits) then the speed in megabytes per
second is equal to the million transfers per second speed. If the current width is Wide (16
bits) then the speed in megabytes per second is twice the million transfers per second speed.
For example, if the current speed is Ultra and the width is Wide then the speed would be 40
megabytes per second.
•
Placement indicates whether the physical drive is in an internal or external storage system.
The following values are valid:
◦ Internal - The physical drive is in an internal storage system.
◦ External - The physical drive is in an external storage system.
◦ Unknown - The physical drive is not in a storage system or the Storage Agents cannot
determine the drive placement.
—This symbol indicates that the drive is a hot plug drive.
•
Rotational Speed indicates the rotational speed of the drive in revolutions per minute.
