HPE 782415-001 2-Port 3PAR StoreServ 20000 10Gbps Ethernet Adapter

The HPE 782415-001 is a purpose-built 2-port 10Gbps Ethernet adapter designed specifically for HPE 3PAR StoreServ 20000 series arrays, frequently used to enable high-throughput file services and accelerate networked storage access for enterprise workloads. Its compact, board-level form factor and two high-speed ports make it an ideal upgrade or replacement option for customers seeking to add or restore 10 Gigabit connectivity to File Persona nodes and related storage controllers.

Key identification details

Search and SKU: HPE/HP part number 782415-001 — commonly labelled in reseller listings and maintenance documentation as “3PAR StoreServ 20000 2-port 10Gbps Ethernet Adapter (File Persona)” or similar. This precise part number is the quickest way to confirm compatibility when checking inventory, cross-referencing maintenance guides, or ordering replacements.

Technical Features & Specifications

Ports, speed and physical interface

The core capability of the 782415-001 is straightforward: two 10 Gigabit Ethernet ports that interface through the array’s adapter slot to provide low-latency, high-bandwidth network access. In typical deployments these ports are used with SFP+ transceivers and fiber or DAC (direct attach copper) patching to connect to top-of-rack switches, converged fabric switches, or directly to host interfaces as part of network-attached storage or clustered file persona topologies.

Performance characteristics

Expect line-rate 10Gb throughput per port under normal operating conditions. The adapter was engineered to offload network and storage-related CPU cycles on the controller by leveraging hardware-level acceleration for storage networking protocols where supported — making it well-suited to mixed workload environments that require both block and file access paths.

protocols and use cases

Typical protocol scenarios for the 782415-001 include 10GbE networking for File Persona (file services), and in many cases the 10Gb adapter is used alongside or in support of converged network stacks such as iSCSI and FCoE where the host array and network are configured accordingly. For customers operating File Persona on 3PAR arrays, the 10Gb adapter provides the necessary network throughput for scale-out file access and high concurrent client counts.

Form factor & installation notes

The adapter is a board-level module that installs into the designated network/adapter bay on compatible 3PAR controller nodes. It is not a standard PCIe server NIC; rather it integrates into the 3PAR hardware design (controller node adapter slot) and must be installed, configured, and recognized through the 3PAR management stack. Always refer to the targeted controller's maintenance guide for safe installation steps and any firmware dependencies.

Compatibility & Systems

Primary compatibility matrix

The 782415-001 is specifically intended for the HPE 3PAR StoreServ 20000 family and related controller node SKUs and configurations where File Persona or 10Gb network ports are required. Because HPE has offered many controller and adapter permutations across the 3PAR portfolio, verify compatibility with the exact controller model and firmware level before purchase. HPE’s product support pages and 3PAR datasheets list supported adapter SKUs by controller model and are the authoritative source for final confirmation.

Interoperability with network fabrics

When deployed, the adapter typically connects to enterprise 10GbE switches and converged fabric switches that provide iSCSI, NFS, SMB/CIFS routing or FCoE bridging. Check switch vendor support for features like jumbo frames, flow control, and link aggregation to obtain the best storage-network performance with 3PAR arrays.

Advantages & Business Value

The central benefits revolve around three themes: throughput, compatibility, and cost-efficiency. The two 10Gb ports deliver a significant network uplift over legacy 1Gb connections, enabling faster file-level throughput and a higher number of concurrent clients. Because this adapter is an OEM HPE part tailored for 3PAR hardware, it integrates seamlessly into supported platforms and reduces the risk of firmware or feature incompatibility that aftermarket adapters sometimes introduce.

Performance uplift and consolidation

By moving to 10Gb, organizations can consolidate multiple 1Gb client or server links into a smaller number of 10Gb links, reducing switch port counts and simplifying cabling while enabling higher aggregate bandwidth for storage workloads.

Cost and lifecycle considerations

For customers operating within a 3PAR ecosystem, replacing or upgrading to the 782415-001 is often more cost-effective than retrofitting alternate vendor adapters. Refurbished and surplus markets commonly carry this SKU, providing an economical path for array refresh and sustaining maintenance operations.

Software and management

Management and configuration of the adapter’s functionality are handled via the 3PAR OS and the system’s management console (Web Client / CLI). Typical operations include link configuration, VLAN tagging for multi-tenant environments, jumbo frame settings for large-block IO, and failover configurations at the network level (LACP/link aggregation).

Firmware alignment

Make sure any adapter being installed matches or is compatible with the array’s OS and controller firmware level. HPE support documentation and Product Information Reference guides list compatible firmware sets and any required updates prior to adapter installation.

Step-by-step high-level

Installation normally includes powering down the node if the specific controller and adapter require it (check the maintenance guide), inserting the adapter into the appropriate bay, applying transceivers/cables, powering up the node, and validating link status in the 3PAR management console. After physical installation verify that the controller OS recognizes the adapter and shows the expected NIC ports. If the deployment includes File Persona or clustered storage services, validate client connectivity and throughput post-install.

Use Cases, Real-World Scenarios & Workload Examples

High-concurrency file serving (File Persona)

For organizations that run File Persona on 3PAR systems (serving NFS and SMB clients), the 782415-001 provides the throughput needed to support hundreds of concurrent users and heavy metadata workloads. Upgrading from 1Gb links to 10Gb substantially reduces per-client latency and improves multi-client performance in read-heavy or mixed read/write scenarios.

iSCSI and converged fabrics

In environments where block storage is provided over Ethernet (iSCSI) or where Fibre Channel over Ethernet (FCoE) is used, the adapter contributes to lower-latency block IO and higher IOPS potentials when paired with fast back-end media (e.g., flash arrays or hybrid configurations). Ensure network fabrics are correctly configured for storage traffic prioritization and isolation where required.

Edge and remote office consolidation

Remote data center or edge deployments that need consolidated storage with fewer physical switch ports can use 10Gb adapters to aggregate multiple smaller links or to provide headroom for future growth without significant re-cabling.

Replacement, Upgrades & Alternative Options

When to replace vs repair

Replace the adapter if physical port damage, repeated errors, or failed hardware diagnostics indicate a board-level fault. Repair is typically not an option for board modules in production arrays; most vendors and data center operations prefer replacement with a known-good module to minimize downtime and ensure long-term reliability.

Upgrading within the 3PAR portfolio

If you require higher aggregate bandwidth or additional ports, consider whether your controller supports multi-port adapters or whether adding multiple 10Gb adapters (where slots permit) provides the desired scaling. Some environments benefit from aggregated links across multiple adapters for redundancy and throughput scaling.
