HP Insight Management Agents - Manual (Page 42)

NOTE: A value of Unknown indicates that the agents cannot determine this information
from the physical drive.
•
Current Width—Displays the current negotiated data transfer width for a SCSI 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 rate for a SCSI physical drive.
The possible values are:
◦ Asynchronous—The negotiated data transfer rate for this drive is asynchronous.
◦ Fast—The negotiated data transfer rate for this drive is 20 megabytes per second.
◦ Ultra—The negotiated data transfer rate for this drive is 40 megabytes per second.
◦ Ultra2—The negotiated data transfer rate for this drive is 80 megabytes per second.
◦ Ultra3—The negotiated data transfer rate for this drive is 160 megabytes per second.
◦ Ultra320—The negotiated data transfer rate for this device is 320 megabytes per second.
◦ Unknown—The agent is unable to determine the negotiated data transfer rate for this
drive.
NOTE: If the negotiated data transfer width is Narrow (8 bits), the actual data transfer rate
is equal to half the negotiated data transfer rate. For example, if the current negotiated data
transfer rate is Ultra (40 megabytes per second) and the width is Narrow, then the actual
data transfer rate is 20 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.
•
Drive Type—Indicates the type of physical drive. The following values are valid:
SCSI—The physical drive is a parallel SCSI drive. ◦
◦ SATA—The physical drive is a Serial ATA drive.
◦ SAS—The physical drive is a Serial attached SCSI drive.
◦ Unknown—The Storage Agents cannot determine the drive type.
•
Media Type—Indicates the type of media the physical drive is composed of. The following
values are valid:
◦ Rotating Platters—Indicates that the physical drive media is composed of rotating platters.
◦ Solid State—Indicates that the physical drive media is composed of solid state electronics.
◦ Unknown—Indicates that the Storage Agents cannot determine the media type.
