Hp Hp Hstns Bc29 N 3Gb 8 Port Sas 20 Bl C Switch — High-Performance Storage Switch for Blade Servers (HP)

How Much Does HP HSTNS-BC29-N 3GB 8-Port SAS 2.0 BL-C Switch Cost in 2026?

As of July 2026, the HP HSTNS-BC29-N 3GB 8-Port SAS 2.0 BL-C Switch is typically available in the used/refurbished market for $115. This price reflects a condition grade of B, meaning the unit has been tested and repaired but may show signs of wear. Refurbished units from vendors like Axus Technology and Ferrotec typically fall within this range, offering a 40–60% cost savings compared to the original new price, which was around $280–$300.

If a facility fails to source a compatible switch in a timely manner, the downtime cost can exceed $500 per hour in mission-critical environments. Therefore, sourcing a reliable used unit is a cost-effective alternative to waiting for new stock or paying premium prices for last-chance availability.

It's important to note that condition grading is not always consistent across vendors. A B-grade unit may have had minor repairs or component replacements, so buyers should always request a detailed inspection report and verify the seller's testing procedures. Units with a C-grade or lower are generally not recommended unless the budget is extremely constrained and downtime is not a concern.

HP HSTNS-BC29-N 3GB 8-Port SAS 2.0 BL-C Switch Specifications and Compatible Tools

The HP HSTNS-BC29-N is a 3GB-per-second SAS 2.0 switch designed for use in HP BladeSystem c-Class enclosures. It supports up to 8 ports and is typically used to connect storage devices to blade servers in a high-availability configuration. The switch is commonly rated for a lifecycle of approximately 100,000 RF hours or 15 years of continuous operation under normal conditions.

This part is compatible with HP BladeSystem c7000 enclosures and blade servers such as the HP ProLiant BL460c Gen8 (2013–2015 production years). It is not compatible with newer Gen9 or Gen10 blade systems, which use different backplane and SAS switch architectures.

Using an incompatible switch, such as the HP HSTNS-BC29-NA (which supports SAS 3.0), can lead to performance degradation or complete failure to initialize the storage subsystem. In such cases, the server may fail to boot, resulting in up to $1,500 in lost productivity and repair costs.

As with many legacy parts, verify with the seller that the unit is specifically the HSTNS-BC29-N and not a visually similar but functionally different variant.

What to Check Before Buying a Used HP HSTNS-BC29-N 3GB 8-Port SAS 2.0 BL-C Switch in 2026

1. Verify the Part Number: Ensure the unit is labeled as HP HSTNS-BC29-N and not a similar part like the HSTNS-BC29-NA. A mismatch can result in incompatibility and system failure.

2. Check the Production Year: Units produced before 2015 are more likely to be available in the used market. Units older than 12 years may have degraded capacitors or connectors, increasing the risk of early failure.

3. Request a Functional Test Report: Ask the seller to provide a test log that includes SAS link negotiation, port initialization, and throughput testing. A unit should maintain at least 2.5GB/s throughput under load.

4. Inspect for Physical Damage: Look for bent pins, corrosion, or signs of overheating. A damaged connector can lead to intermittent failures, costing up to $800 in diagnostics and rework.

5. Reject if the Unit Has Not Been Recalibrated: Some used switches may not have had their firmware updated or recalibrated. A unit that hasn’t been updated since 2018 or later should be rejected, as it may not support newer firmware versions required by blade servers.

Failing to perform these checks can result in a non-functional unit, leading to extended downtime and the need to source a replacement, which could cost an additional $200–$300 in expedited shipping and labor.

FAQ

Q: Can I use the HP HSTNS-BC29-N in a Gen10 blade system?
A: No. The HSTNS-BC29-N is designed for Gen8 systems and is not compatible with Gen10 blade servers. Attempting to use it in a Gen10 system can cause a boot failure and may damage the backplane.

Q: What’s the difference between the HSTNS-BC29-N and HSTNS-BC29-NA?
A: The HSTNS-BC29-NA supports SAS 3.0 (6GB/s) and has a different firmware architecture. Using the wrong model can lead to performance issues or incompatibility, especially in systems requiring SAS 2.0.

Q: How long can I expect a used HSTNS-BC29-N to last?
A: A well-maintained unit can last up to 8–10 years in a controlled environment. However, capacitors and connectors may degrade after 12 years, so it's best to source units produced after 2014.

Q: Should I buy a B-grade unit or wait for a higher grade?
A: A B-grade unit is typically a good balance between cost and reliability, especially if it has been fully tested and recalibrated. A C-grade unit may be too risky unless downtime is not a concern.

Q: What’s the average savings when buying used instead of new?
A: You can expect to save 40–60% by purchasing a used HSTNS-BC29-N compared to a new unit. For example, a used unit at $115 versus a new one at $280 represents a $165 cost saving.
