HPE 800 GB SAS SSD for ProLiant Gen9

This 2.5 inch solid-state drive uses a 12 Gb/s SAS interface to deliver high random read and write IOPS for HPE ProLiant servers including Gen9 and HPE Synergy platforms. It is categorised as a Mixed Use drive so you can match the endurance tier to your workload demands. The SFF form factor fits hot-plug and non-hot-plug bays as well as Quick Release carriers.

Thermals noise and power in normal use

The NAND flash design reduces power consumption compared with traditional spinning drives while maintaining consistent latency under load. No moving parts means silent operation inside the server chassis. Lower draw helps the platform stay within its thermal envelope during sustained mixed-use workloads.

SmartSSD Wear Gauge and flexible carriers

HPE SmartSSD Wear Gauge compatibility lets management tools monitor remaining drive life and prevent unexpected data loss. The drive ships in a Small Form Factor package that supports hot-plug, non-hot-plug and Quick Release installation options. Retail or OEM packing may vary but the drive itself is new.

Questions about this item

How do I install the 846434-B21 2.5" SAS drive in an HPE ProLiant Gen9 server, and what step is often missed?

Slide the SFF drive into a hot-plug bay until the carrier latch clicks; the step often missed is running the HPE SmartSSD Wear Gauge baseline scan in the management tool before putting the drive into production.

What maintenance or replacement will the 800 GB SAS SSD need later?

Monitor the HPE SmartSSD Wear Gauge for remaining endurance; when the gauge reaches its threshold, replace the drive to avoid data loss — no other scheduled maintenance is required.

What limit appears first on the 12Gb/s SAS SSD under sustained write workloads?

The write-intensive endurance rating is the first limit reached; the SmartSSD Wear Gauge will report decreasing life as program-erase cycles accumulate.
