Hp Hpe 691367 B21 Blc Virtual Connect Flexfabric 2040 F8 Modul — High-Performance Networking Module for Blade Servers (HP)

How Much Does HPE 691367-B21 BLC Virtual Connect FlexFabric-20/40 F8 Module Cost in 2026?

As of July 2026, the HPE 691367-B21 BLC Virtual Connect FlexFabric-20/40 F8 Module is priced in the range of $68–$68, depending on the condition grade and vendor. On the used/refurbished market, you can expect to pay around $68 for a module in condition grade B, which is the most common grade available. Reputable vendors like Axus Technology and Ferrotec typically offer these modules at a 40–60% discount compared to new units, which can cost upwards of $150–$180.

Buying a used module can save you hundreds of dollars, but it’s important to understand the risk. A failed module can lead to extended server downtime, with costs averaging $1,200–$2,000 per hour in mission-critical environments. That’s why it’s crucial to verify the condition and test results before purchase. Modules with more than 10,000 RF-hours or signs of physical stress are more likely to fail prematurely. Always ask for a burn-in test or a 72-hour stress test from the seller.

HPE 691367-B21 BLC Virtual Connect FlexFabric-20/40 F8 Module Specifications and Compatible Tools

The HPE 691367-B21 is a FlexFabric module designed for HP BladeSystem c-Class enclosures, typically used in data centers for high-speed, low-latency networking. It supports 10/20/40GbE and Fibre Channel over Ethernet (FCoE) and is commonly found in systems like the HP BladeSystem c7000. The module typically has a lifecycle of around 8–10 years, with a recommended replacement after 10,000 RF-hours or 5 years of continuous operation.

This module is compatible with HP BladeSystem c7000 enclosures (2013–2017 production years) and the HPE Virtual Connect Manager. However, it is not compatible with newer FlexFabric-20/40 Gen10 modules (part number 691367-B22). Using an incompatible module can lead to configuration errors and system instability, potentially causing a full enclosure shutdown and downtime of 4–8 hours.

What to Check Before Buying a Used HPE 691367-B21 BLC Virtual Connect FlexFabric-20/40 F8 Module in 2026

1. Production Year: Verify the module was manufactured between 2013 and 2017. Units older than 2012 may have exceeded their service life and are more likely to fail.

2. RF-Hours: Ask for the number of RF-hours. Modules with more than 10,000 RF-hours should be rejected due to high risk of failure.

3. Burn-In Test: Request a 72-hour burn-in test. Modules that pass this test are significantly more reliable.

4. Physical Inspection: Look for signs of physical stress, such as bent connectors or cracked PCBs. Reject if any are found.

5. Firmware Version: Confirm the firmware is up to date and compatible with your enclosure. Outdated firmware can cause interoperability issues.

Buying a faulty module can lead to a full enclosure shutdown and downtime of 6–10 hours, with associated costs of $1,500–$3,000. Always work with a vendor that offers a 30-day return policy.

FAQ

Q: Can I use the HPE 691367-B21 in a newer HP BladeSystem c7000 Gen10?

A: No. The HPE 691367-B21 is not compatible with Gen10 systems. You’ll need the HPE 691367-B22 or later model. Using the wrong module can cause configuration errors and system instability.

Q: Should I replace my HPE 691367-B21 module after 5 years?

A: Yes. Even if it’s still working, it’s recommended to replace it after 5 years or 10,000 RF-hours. Modules beyond this threshold are more likely to fail, with a 30–40% higher risk of failure.

Q: How long does the HPE 691367-B21 typically last under normal use?

A: On average, the module lasts 8–10 years under normal data center conditions. However, in high-traffic environments, it may need replacement after 5–7 years.

Q: What’s the difference between the HPE 691367-B21 and the HPE 691367-B22?

A: The B22 is a Gen10-compatible version with updated firmware and improved power efficiency. The B21 is not compatible with Gen10 systems and lacks support for newer blade models.

Q: What test methods should I ask for when buying a used HPE 691367-B21?

A: Ask for a 72-hour burn-in test and a link integrity test. These tests can identify latent failures and ensure the module is stable under load. Modules that pass both tests are 90% more likely to function correctly in the field.
