480GB, M.2, NVMe Solid State Drive 8214991 Specification
NVMe Storage Drive 8214991 specifications are listed in the following table.
480GB NVMe M.2 Solid State Drive Specification
Value
3.80 mm +/-0.18 mm
22.00 mm +/-0.15 mm
80.00 mm +/- 0.15 mm
Up to 11 g
Value
Refer to the server product notes for minimum operating
system versions, hardware, firmware, and software
compatibility.
Provides alerts for proactive replacement of the drive before
the endurance is depleted. Provides endurance remaining in
NVMe SMART logs. SSD supports the standard method
defined by NVMe for Solid State Drive to report NAND wear
through the "Get Log" command SMART/Health Information
Percentage Used field. The units are whole percentage of
wear.
Percentage Used: Contains a vendor specific estimate of the
percentage of NVM subsystem life used based on the actual
usage and the manufacturer's prediction of NVM life. A value
of 100 indicates that the estimated endurance of the NVM in
the NVM subsystem has been consumed, but may not
indicate an NVM subsystem failure. The value is allowed to
exceed 100. Percentages greater than 254 are represented
as 255. This value is updated once per power-on hour (when
the controller is not in a sleep state).
Refer to the JEDEC JESD218A standard for SSD device life
and endurance measurement techniques.
Energy storage components complete buffered writes to the
persistent flash storage in case of a sudden power loss.
Supports testing of the power loss capacitor. Power is
monitored using SMART (Self-Monitoring, Analysis, and
Reporting Technology) attribute critical warning.
Managed through the SMBUS. Provides out-of-band
management by means of SMBUS interface. SMBUS access
includes NVMe-MI, the VPD page and temperature sensor.
For more information about management utilities, refer to the
server documentation.
