High-Density Flex-10 Architecture

The Flex-10 10D module supports multi-virtual NIC capability, enabling a single physical 10GbE link to be subdivided into multiple FlexNICs. This approach allows greater consolidation and more efficient use of server I/O resources while preserving isolation between logical interfaces.

Bandwidth Partitioning and QoS

Administrators can assign bandwidth pools and quality-of-service parameters to each virtual function. These capabilities let you guarantee throughput for critical workloads while preventing noisy neighbors from affecting application performance.

Compatibility & Form Factor

Specifically built for the HPE c-Class blade chassis and compatible server blades, the 638528-001 module mounts in supported mezzanine slots. Verify firmware and chassis compatibility when integrating into legacy or upgraded BladeSystem environments.

Top benefits at a glance

  • Consolidated cabling: fewer external cables by multiplexing traffic over higher-speed links.
  • Operational flexibility: reassign bandwidth to workloads on-the-fly through logical configuration.
  • Cost efficiency: reduced switch port consumption and improved utilization of network resources.
  • Improved manageability: central control via HPE Virtual Connect tools simplifies lifecycle tasks.

Typical Use Cases

Virtualized Data Centers

When hosting numerous virtual machines on blade servers, Flex-10's logical NICs allow administrators to segment traffic per VM or service tier without adding physical NICs.

High-Performance Compute & Storage Networks

Combining high throughput with predictable QoS makes the Flex-10 module a strong candidate for compute clusters or storage front-ends that require consistent, low-latency connectivity.

Performance Considerations & Tuning

Balancing throughput and isolation

Virtual partitioning increases flexibility but requires attentive tuning: oversubscription can conserve resources but may cause contention during peak loads. Define conservative baseline bandwidth guarantees for mission-critical services.

Latency and packet handling

For latency-sensitive workloads, reduce unnecessary intermediate buffering and ensure QoS prioritization is consistent across the virtualization stack and physical network devices.

Comparisons & Alternatives

While Flex-10 modules are strong for c-Class blade consolidation, consider these alternatives depending on your priorities:

  • Standard 10GbE NICs: Simpler in homogeneous rack server setups but less flexible for logical partitioning.
  • Converged network adapters (CNAs): Combine storage and network offload features—useful where iSCSI or FCoE is dominant.
  • Newer 25/40/100GbE fabric modules: Offer higher raw capacity but may require extensive infrastructure changes.

Procurement & Replacement Advice

Buying tips

  • Purchase from reputable distributors that provide clear part-number confirmation (638528-001).
  • When possible, buy modules with a matching warranty or service contract to your chassis.
  • Consider refurbished or open-box options for budget projects — but verify firmware and physical condition carefully.

End-of-life and upgrade paths

Check HPE product lifecycle documentation for end-of-life dates. If your environment plans to scale significantly or adopt newer Ethernet standards, plan migration paths early to minimize disruption.

Design and Architecture

The design of the HP Virtual Connect Flex-10 10D Module emphasizes streamlined integration into c-Class enclosures. With a compact and modular form factor, it installs directly into the blade chassis, eliminating the need for multiple network interface cards (NICs) and external switches. The architecture is built to handle intensive workloads by offering dual 10Gb connections with Flex-10 technology, which allows administrators to split physical 10Gb Ethernet ports into multiple logical NICs for more efficient bandwidth allocation.

Space Optimization

By consolidating I/O modules, the 638528-001 maximizes rack space and reduces clutter, enabling organizations to achieve higher density computing without sacrificing performance. This design supports a cleaner data center environment, minimizes energy consumption, and contributes to lower total cost of ownership (TCO).

High Availability

The module supports redundant configurations to ensure uninterrupted networking services. Paired modules can be deployed for failover protection, offering resilience against network downtime and ensuring continuous availability for mission-critical applications.

Features of HP Virtual Connect Flex-10 10D Module

  • Supports HP c-Class BladeSystem enclosures with simplified I/O architecture.
  • Virtual Connect technology reduces cables and streamlines connectivity management.
  • Flex-10 capabilities allow up to four virtual NICs per physical 10Gb connection.
  • Improved bandwidth allocation for diverse workloads and applications.
  • Integrated network virtualization to support server mobility and provisioning.
  • Redundant architecture for high availability and fault tolerance.
  • Scalability to adapt to growing data center needs and dynamic workloads.

Performance and Bandwidth Management

One of the defining capabilities of the 638528-001 module is the use of Flex-10 technology. This innovation enables administrators to divide a single 10Gb Ethernet port into multiple virtual adapters, assigning bandwidth levels according to workload requirements. As a result, mission-critical applications can be allocated more bandwidth, while secondary workloads receive appropriate resources without overprovisioning.

Workload Optimization

With workload-specific bandwidth allocation, businesses can ensure smooth operations for database systems, virtualization clusters, and application servers. Flex-10 ensures optimized throughput and reduces network congestion across the blade environment.

Scalable Throughput

The dual 10Gb connections allow the module to scale to high-demand environments. As enterprise applications grow in complexity, the module ensures servers maintain consistent access to network resources without degradation in performance.

Management and Virtualization Capabilities

Management efficiency is a key advantage of deploying the HP Virtual Connect Flex-10 10D Module. Administrators can utilize a centralized interface to provision, configure, and monitor networking resources across the blade chassis. With embedded Virtual Connect Manager, routine tasks like profile management and server reassignments become streamlined.

Virtual Connect Manager

This embedded management tool provides a browser-based console for configuring server profiles, allocating MAC addresses, and managing SAN and LAN connections. It reduces reliance on traditional network teams by empowering server administrators with networking control at the enclosure level.

Server Mobility

By decoupling the server identity from physical hardware, the module enhances server mobility. IT teams can move workloads or replace hardware without complex network reconfiguration. This capability accelerates disaster recovery, hardware refreshes, and scaling operations in cloud or hybrid environments.
