HP Insight Management Agents - Manual (Page 43)

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.
• Negotiated Link Rate—Displays the negotiated link rate for SAS and SATA physical drives.
The possible values are:
— 1.5 Gbps—The negotiated link rate for this drive is 1.5 gigabits per second.
— 3.0 Gbps—The negotiated link rate for this drive is 3.0 gigabits per second.
— 6.0 Gbps—The negotiated link rate for this drive is 6.0 gigabits per second.
— Unknown—The agent is unable to determine the negotiated link rate for this drive.
• NCQ Support—Displays the status of Native Command Queuing support for this drive.
The possible values are:
— No Controller Support—The array controller does not support NCQ.
— No Drive Support—The array controller does support NCQ, but the drive does not.
— Disabled—The array controller and drive support NCQ, but it is disabled.
— Enabled—The array controller and drive support NCQ and it is enabled.
— Unknown—The agent is unable to determine the NCQ configuration for this drive or
it is not a SATA drive.
• Phy Count—Displays the number of phys for each physical drive. Single-ported drives have
one phy. Dual-ported drives have two phys.
• Multipath Status—Displays the overall multipath status of this physical drive. The following
values are valid:
— Not Configured—Indicates that the physical drive is not configured to have multipath
access.
— Redundant—Indicates that the physical drive currently has more than one I/O path to
the controller.
