• Serial Number displays the serial number assigned to the physical drive. This value is based

upon the serial number as returned by the SCSI inquiry command but may be modified due

to space limitations. This item can be used for identification purposes.

• Service Hours displays the current number of hours of service (the number of hours that a

physical drive has been spinning) since the drive was stamped. The drive was stamped when

it left the factory.

For example, if the Current Service Hours value is 604, the drive has been operating for 604

hours. If an error occurred at 499 Service Hours, it occurred after 499 hours of service.

• S.M.A.R.T. Support indicates whether or not the SCSI physical drive supports S.M.A.R.T. The

possible values are:

◦ Available - This drive supports predictive failure monitoring.

◦ Not available - Predictive failure monitoring is not available for this drive.

◦ Unknown - The Storage Agents cannot determine if the drive supports predictive failure

monitoring. You may need to upgrade your driver or Storage Agents.

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.
