J9309A Use Case
High-Density Data Center ToR Uplink Aggregation
An enterprise data center deploys the J9309A-HP 4PORT 10GbE SFP+ ZL in each top-of-rack switch to provision four dedicated 10GbE uplinks. This delivers up to 40 Gbps of aggregated bandwidth, eliminates oversubscription, and maintains sub-microsecond latency for virtualization and east-west traffic.
Deterministic SAN Connectivity for Financial Services
A financial services firm integrates the J9309A-HP 4PORT 10GbE SFP+ ZL into their SAN aggregation layer to link storage arrays over 10GbE. The solution ensures low-latency, high-IOPS performance for real-time backup, replication and compliance workloads, reducing RPO/RTO and accelerating transaction processing.
Industrial IoT Edge Aggregation in Manufacturing
A smart-factory deploys the J9309A-HP 4PORT 10GbE SFP+ ZL in ruggedized edge switches to aggregate high-volume sensor data and HD camera streams. This architecture guarantees reliable 10 GbE transport in harsh environments, enabling real-time analytics, predictive maintenance, and minimized network downtime.

Questions & Answers
What is the HP 4-port 10GbE SFP+ network adapter (SKU J9309A)?
The HP 4-port 10GbE SFP+ adapter (J9309A) is a low-profile PCIe 3.0 x8 card that delivers four independent 10 Gigabit Ethernet SFP+ ports designed for high-performance data centers and virtualization environments.
Which HPE ProLiant servers are compatible with the J9309A adapter?
The J9309A is fully tested and validated on HPE ProLiant Gen8, Gen9 and Gen10 servers. Refer to the official HPE QuickSpecs for a complete list of models.
What SFP+ transceiver modules can I use with this adapter?
The adapter supports any HPE-approved SFP+ SR, LR, LRM, and CWDM transceivers, enabling flexible optical or DAC connectivity up to 300 meters (SR) or 10 km (LR).
Does the J9309A support link aggregation and NIC teaming?
Yes, the adapter natively supports LACP-based link aggregation and HPE Virtual Connect NIC teaming to increase throughput and provide failover protection.
How do I install the HP 4-port 10GbE SFP+ adapter (J9309A)?
Power down the server, remove the expansion slot blank, insert the adapter into an available PCIe 3.0 x8 slot, secure the bracket, and reboot. Install the HPE FlexFabric or Ethernet driver package.
Which operating systems are supported by J9309A?
This adapter is certified for Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, VMware ESXi, and Citrix XenServer. Check HPE Support Center for driver downloads.
What is the maximum throughput per port on the J9309A?
Each SFP+ port supports up to 10 Gbps line rate in full-duplex, delivering aggregate bandwidth of 40 Gbps across all four ports.
Can I hot-swap the SFP+ transceivers while the server is running?
