Hp Hp 451789 001 3Gb 8 Port Sas Bl C Switch Module — High-Performance SAS Switch for Blade Servers (HP)

How Much Does HP 451789-001 3GB 8 Port SAS BL-C Switch Module Cost in 2026?

As of July 2026, the HP 451789-001 3GB 8 Port SAS BL-C Switch Module is priced in the range of $115 for a used, refurbished unit. This price is consistent across most secondary markets, with minimal variance between condition tiers. Units in "B" grade condition, which are typically lightly used and have been professionally refurbished, are the most common and cost around $115. Higher-grade "A" units, which may have less than 10,000 operational hours and come with full calibration, can range up to $130, though these are rare.

Refurbishers like Covalent Materials and Axus Technology are known to source and resell this part with a 40–60% cost savings compared to a new unit, which can exceed $250. For data centers and IT teams managing older HP BladeSystem c-Class enclosures, this represents a significant cost avoidance. A failed or missing switch module can lead to storage connectivity outages, costing upwards of $1,500 in downtime and emergency replacement.

However, it's important to note that the condition of the module can vary. Units with more than 15,000 operational hours or signs of physical stress may not last beyond 6–12 months in high-traffic environments, increasing the risk of unplanned downtime.

HP 451789-001 3GB 8 Port SAS BL-C Switch Module Specifications and Compatible Tools

The HP 451789-001 is a 3GB/sec SAS switch module designed for use in HP BladeSystem c-Class enclosures. It provides eight SAS ports and is commonly used in configurations with HP ProLiant BL460c Gen8 and earlier blade servers. The module is typically rated for up to 10,000 operational hours before requiring maintenance or replacement. It's a critical component for maintaining storage redundancy and performance in blade server environments.

This part is compatible with HP BladeSystem c7000 enclosures and is often used with HP Smart Array controllers. However, it is not compatible with newer SAS 6GB or 12GB modules such as the HP 451790-001. Using an incompatible module can lead to system instability or failure to boot, resulting in up to $2,000 in lost productivity and repair costs.

Given the age of this part—typically manufactured between 2010 and 2014—users should verify the exact model and firmware compatibility with their existing infrastructure. Always check the HP Part Surrogate Tool for the latest compatibility data before deployment.

What to Check Before Buying a Used HP 451789-001 3GB 8 Port SAS BL-C Switch Module in 2026

1. Operational Hours: Ensure the module has less than 12,000 operational hours. Units with more than 15,000 hours are at high risk of failure within 6–12 months.

2. Firmware Version: Confirm the firmware is at least version 3.10. Older versions may not support newer blade server models and can cause boot failures.

3. Physical Inspection: Look for signs of overheating, such as discoloration or warping on the PCB. A warped module can lead to intermittent connectivity and system crashes.

4. Functional Testing: Use a SAS loopback test and a port-to-port signal integrity test. If the module fails either test, it should be rejected outright.

5. Production Year: Avoid modules produced before 2012. These units are more prone to capacitor degradation, which can lead to sudden failure and up to $1,200 in downtime costs.

Purchasing a faulty module can result in storage outages, failed storage arrays, and extended downtime. Always request a full test report and warranty from the seller before finalizing the purchase.

FAQ

Q: Can I use the HP 451789-001 with a newer 6GB SAS switch?
A: No. The HP 451789-001 is a 3GB module and is not compatible with 6GB or 12GB SAS switches like the HP 451790-001. Mixing speeds can cause data corruption and system instability, leading to up to $1,800 in repair costs.

Q: Should I buy a used HP 451789-001 for a mission-critical application?
A: Only if the module has less than 10,000 operational hours and comes with a 90-day warranty. Modules with more than 12,000 hours are not recommended for mission-critical use due to the high risk of failure within 6 months.

Q: How long can I expect the HP 451789-001 to last in a typical data center?
A: With less than 10,000 operational hours, you can expect a lifespan of 2–3 years in a typical data center. Units with more than 12,000 hours may fail within 6–12 months, especially in high-traffic environments.

Q: What is the difference between the HP 451789-001 and HP 451790-001?
A: The HP 451790-001 is a 6GB SAS switch module, while the 451789-001 is 3GB. The 451790-001 supports higher throughput and is not a direct replacement. Using the wrong module can lead to performance bottlenecks and up to $2,000 in lost productivity.

Q: Is it worth buying a used HP 451789-001 instead of new?
A: Yes, if the unit is in good condition and verified for performance. Used modules can save 40–60% compared to new, but only if they pass full testing and have less than 12,000 operational hours. Otherwise, the risk of failure is too high.
