What is a SSD?
An enduring data storage device utilizing NAND (negative-AND) semiconductor technology to store and access data which is volatile
without the aid of an auxiliary power source.
SSD Quality
Today's businesses are seeing larger, more complex applications, coupled with an increasing amount of mission-critical and
transaction processing data demand. In this
environment, storage has become a critical component, significantly defining
requirements for both systems reliability and performance. This is why HPE drives undergo a rigorous qualification process to ensure
functionality and eliminate firmware and OS incompatibilities.
Integration
Many issues customers have with third party drives are "simple" integration issues. When buying from another supplier, there is no
guarantee that a drive has been correctly set for proper operation with ProLiant servers
and storage systems. These incompatibilities
can create problems in configuration, can rob your system of performance, or at their worst, can cause you to lose data. HPE
drives
are specifically designed and tested for flawless operation in your HPE equipme
nt. The integration of solid state drives in HPE
systems means that associated components are right for your ProLiant server.

Product Category
HPE Enterprise SSDs are available in three categories based on workload level: Read Intensive (RI), Mixed Use (MU), and Write
Intensive (WI).
These categories indicate the number of drive writes per day (DWPD1) that you can expect from the drive. (DWPD
is the maximum number of 4K host writes to the entire drive capacity of the SSD per day over a five-year period).
Maximum Usage Limitations
NAND Flash devices use semiconductor technology that has a finite number of data that can be written to the device, defined as the
Maximum Usage Limit, commonly called “Write Endurance”. Write Endurance -
is measured while running 100% random 4KiB writes
across the entire SSD.
Drive Writes Per Day (DWPD) -
Workload environment is based on 100% random 4KiB writes for five (5) years, which is the maximum
amount of data that can be written to the device before reaching the device's write endurance limit.
HPE
Solid State Drives (SSDs) are equipped with tools that can report the amount of lifetime remaining. Introducing HPE SMARTSSD
Wear Gauge™. To take advantage of SMARTSSD Wear Gauge™, Smart Array Firmware version 5.0 or greater is required and HPE
Array Configuration Utility (ACU) or HPE Diagnostic Utility (ADU) must be running.
Simple Network Management Protocol (SNMP) Storage Agents for both Microsoft® Windows® and Linux provide status and
condition updates through traps, OS event logs and the HPE System Management Homepage:
