Overview
831735-B21 Overview
HPE PCIe x4 Lanes Read Intensive HHHL 3yr Wty Card, 1.6 TB, Half-Height/Half-Length (HH/HL), 2550 MB/s
831735-B21 is a HPE 1.6TB PCIe x4 Lanes Read Intensive HHHL 3yr Warranty Card Supports Select Gen9 Servers. HPE PCIe Workload Accelerators for HPE ProLiant ML/DL/SL Server series are PCIe card-based direct-attach solid state storage technology solutions for application performance improvement. They offer excellent latency and enterprise reliability for improving an individual server's throughput, and allow you to implement up to ten times the number of virtual machines compared to typical virtualization environments.
With significant energy savings and a reduced footprint, your total cost of ownership will be lower. Performance constrained applications such as on-line transaction processing (OLTP), virtual desktop infrastructure (VDI), or Big Data will greatly benefit by adding a PCIe Workload Accelerator to their server.

Frequently Asked Questions
What primary server generations are compatible with the HPE 831735-B21 1.6TB drive? +
The HPE 831735-B21 is specifically engineered for integration with select HPE ProLiant Gen9 servers. This PCIe-based storage solution is optimized to work within the Gen9 architecture, ensuring seamless hardware recognition and reliable performance. We recommend verifying your specific server model’s firmware and slot compatibility to ensure optimal hardware integration and system stability.
Is the 831735-B21 suitable for write-heavy database workloads? +
This drive is classified as a Read Intensive (RI) solid-state storage device. It is designed for workloads that prioritize high-speed data retrieval, such as boot volumes, web servers, or read-heavy application environments. For write-intensive enterprise databases or high-frequency logging applications, we recommend exploring our catalog for Write Intensive (WI) or Mixed Use (MU) HPE SSD options.
What is the form factor and interface of this HPE 1.6TB storage drive? +
The 831735-B21 features a Half-Height, Half-Length (HHHL) form factor and utilizes a high-performance PCIe x4 interface. This design allows it to plug directly into a PCIe expansion slot on your compatible server, bypassing traditional SAS/SATA backplanes to deliver lower latency and increased throughput for IO-sensitive enterprise applications.
How does the PCIe interface impact performance compared to standard SATA SSDs? +
By leveraging the PCIe x4 interface, this drive significantly reduces data bottlenecks found in traditional SATA or SAS storage controllers. This architecture allows the drive to communicate directly with the system bus, providing the high bandwidth and low latency required for enterprise-grade performance. It is an ideal upgrade for environments where traditional drive interfaces cannot keep up with data demand.
Does the 831735-B21 require special drivers or additional configuration? +
In most compatible Gen9 HPE server environments, the system BIOS and existing storage drivers will recognize the PCIe device automatically. However, we advise ensuring your server is running the latest Service Pack for ProLiant (SPP) to ensure the drive operates with the most current firmware and drivers provided by HPE, which maximizes stability and drive lifespan.
Can I install this drive in an existing server without downtime? +
Because this unit installs into a PCIe slot, it is generally considered a non-hot-pluggable device in most ProLiant server configurations. You will likely need to power down the server to safely seat the card into the PCIe riser. Please consult your server's technical manual regarding the specific PCIe slot lane capabilities and power requirements before performing the installation.
What does the 'Read Intensive' classification mean for my data storage strategy? +
Read Intensive (RI) drives are balanced for maximum efficiency in environments where the primary task is reading data. These drives are endurance-optimized for tasks like content delivery, data analytics, and cached information. By deploying this in a compatible Gen9 server, you ensure that your read-heavy applications experience minimal lag and high sustained input/output operations per second.
Are there specific power requirements for this HHHL PCIe drive? +
The drive draws its power directly from the PCIe slot on your Gen9 server's riser card. Since this drive is validated for HPE servers, it adheres to the standard PCIe power draw specifications defined for those slots. Ensure your server power supply unit (PSU) has sufficient overhead to handle the combined load of all installed PCIe expansion cards.
How can I obtain a bulk quote for multiple 831735-B21 units? +
