Enterprise SAS SSD for mixed workloads

The HPE P49049-B21 is a 1.6 TB solid state drive built for 24Gb/s SAS infrastructure. It targets data centres running analytics, cloud, high performance compute, database and virtualization workloads. The mixed use rating balances read and write endurance for varied application demands.

Thermals noise and power in operation

The drive uses the SAS interface without moving parts, so acoustic output is negligible in a server chassis. Power draw scales with the 24Gb/s link speed and the quoted IOPS figures. No separate cooling hardware is required beyond standard enclosure airflow.

2.5 inch form factor and SAS connectivity

The 2.5" housing fits common drive bays and backplanes designed for SAS devices. A 24Gb/s SAS controller and updated server platform are needed to reach the full 155000 random read and 165000 random write IOPS. The drive remains compatible with 12Gb/s SAS ecosystems for deployment flexibility.

Questions about this item

How do I install the P49049-B21 into a 2.5" SAS bay and what step is often missed?

Slide the 2.5" drive into the hot-plug carrier until the connector seats firmly on the 24Gb/s SAS backplane; the step often missed is confirming the controller firmware supports 24Gb/s SAS-4 speeds before powering on.

What maintenance or replacement will the 1.6TB mixed-use SSD need later?

The drive has no user-serviceable parts; replacement is required once the mixed-use endurance rating is reached or if SMART attributes report media wear or uncorrectable errors.

What limit appears first on the P49049-B21 during sustained mixed-use workloads?

Sustained writes will hit the mixed-use endurance ceiling before the 155000 random read IOPS or 165000 random write IOPS limits are reached.
