Owner's manual

• SmartSSD Usage Remaining—Displays the percentage of life remaining for this solid state
disk.
• Estimated Life Remaining based on workload to date—Indicates the estimated total number
of days that the this solid state disk has remaining based on the current write workload.
• Power On Hours—Indicates the total number of hours that the physical disk has been powered
on.
• SSD Wear Status—Indicates the solid state disk wear status of the physical drive selected. The
following values are valid:
◦ OK—The solid state disk is not in any imminent danger of wear out.
◦ 56 day threshold passed—Indicates that based upon the current workload, the solid state
disk will reach the maximum usage limit for writes (wear out) within fifty-six days. You
should modify your write workload or begin preparing to replace your SSD drive.
◦ 5 percent threshold passed—Indicates that the solid state disk has passed the five percent
threshold and is at or below five percent of reaching the maximum usage limit for writes
(wear out). You should begin to prepare to replace your SSD drive.
◦ 2 percent threshold passed—Indicates that the solid state disk has passed the two percent
threshold and is at or below two percent of reaching the maximum usage limit for writes
(wear out). You should begin to prepare to replace your SSD drive.
◦ SSD Wear Out—Indicates that a solid state drive is approaching the maximum usage
limit for writes (wear out) and should be replaced as soon as possible.
◦ Unknown—The Storage Agents cannot determine the solid state wear status of this physical
drive. You may need to upgrade your driver software or Storage Agents.
SAS Logical Drive
Select a SAS logical drive from the SAS host bus adapter submenu to display the following
information:
• Status —Shows the status of the physical drive selected.
OK—The logical drive is in normal operation mode. No user action is required.◦
◦ Degraded—The logical drive is in a degraded state.
◦ Failed—There are more failed physical drives than the fault tolerance mode of the logical
drive can handle without data loss.
◦ Offline—The logical drive is offline and cannot be accessed by the operating system.
User action may be required to bring the drive back online.
◦ Unknown—The Storage Agents cannot determine the status of this drive. You may need
to upgrade your driver software or Storage Agents.
• Raid Level—Displays the raid configuration of the logical drive. The possible values are:
RAID 0–Fault tolerance is not enabled. If a physical drive reports an error, the data cannot
be recovered.
◦
◦ RAID 1– Mirroring is the highest level of fault tolerance. It is the only method offering fault
tolerance protection if no more than two physical drives are selected. Drive mirroring
creates fault tolerance by storing duplicate data on two drives. There must be an even
number of drives. This is the most costly fault tolerance method because it requires 50
percent of the drive capacity to store the redundant data.
◦ Unknown—The Storage Agents cannot determine the raid configuration of this logical
drive. You may need to upgrade your driver software or Storage Agents.
