Dell Dell Poweredge M640 H330 Mini Blade Chassis — Compact Server Infrastructure for High-Density Data Centers (Dell)

How Much Does Dell PowerEdge M640 H330 Mini Blade Chassis Cost in 2026?

As of July 2026, the Dell PowerEdge M640 H330 Mini Blade Chassis is priced at $373 in the used market, typically in B-grade condition. This price reflects a 40–60% cost savings compared to the original manufacturer’s pricing when new, which was in the $600–$800 range. Refurbishers like Axus Technology and Ferrotec commonly list this part in their inventory, often with a 12-month warranty included.

The cost of failure is significant: a failed chassis can bring down an entire blade server setup, leading to downtime costs of $1,500–$3,000 per hour in mission-critical environments. It’s also important to note that while the price is stable, the condition of the chassis can vary. Units with more than 100,000 operational hours or signs of physical wear may not perform reliably, even if they pass basic tests.

Dell PowerEdge M640 H330 Mini Blade Chassis Specifications and Compatible Tools

The Dell PowerEdge M640 H330 Mini Blade Chassis is a compact, 1U server chassis designed to house up to four blade servers. It typically supports 1200W power supplies and is compatible with Dell PowerEdge M640 blade servers. The chassis is commonly rated for up to 100,000 operational hours before requiring maintenance. It was typically in production from 2016 to 2019, so most units in the used market are between 7 and 10 years old.

This chassis is compatible with Dell’s H330 RAID controller and works with most Dell PowerEdge M640 blade servers. However, it is not compatible with newer M1000e chassis-based blade servers due to differences in backplane architecture. Using an incompatible chassis can lead to boot failures and data corruption, with repair costs averaging $2,000–$3,500.

What to Check Before Buying a Used Dell PowerEdge M640 H330 Mini Blade Chassis in 2026

1. Verify the production year: Units made before 2017 may have early firmware issues. Reject any unit older than 2015.
2. Check operational hours: Use a Dell diagnostic tool or ask the seller for the last service log. Units with more than 80,000 hours are at high risk of failure.
3. Run a power-on test: Ensure the chassis powers up and recognizes all blade servers. A failure to detect blades indicates a faulty backplane.
4. Inspect the physical condition: Look for bent rails, corrosion, or signs of water damage. Reject if the chassis has visible rust or bent components.
5. Confirm firmware compatibility: The firmware should be at least version 2.1.0 to support modern blade servers. Older versions may not recognize newer blades.

A poorly vetted chassis can lead to extended downtime, with average repair or replacement costs reaching $4,000–$6,000 in enterprise environments.

FAQ

Q: Can I use the Dell PowerEdge M640 H330 Mini Blade Chassis with a Dell PowerEdge M1000e blade server?
A: No. The M640 H330 chassis is not compatible with the M1000e due to differences in backplane architecture. Attempting to use them together can result in boot failures and data loss, with repair costs averaging $2,500.

Q: Should I buy a used Dell PowerEdge M640 H330 Mini Blade Chassis with over 80,000 hours of use?
A: No. Units with more than 80,000 hours are at high risk of failure. The average failure rate for these units exceeds 30% beyond that threshold, leading to downtime costs of $1,500–$3,000 per hour.

Q: How long can I expect the Dell PowerEdge M640 H330 Mini Blade Chassis to last with proper maintenance?
A: With regular firmware updates and power supply checks, the chassis can last up to 10 years. However, most units in the used market are between 7 and 10 years old, so expect a remaining lifespan of 2–5 years.

Q: What is the difference between the Dell PowerEdge M640 H330 and the standard M640 chassis?
A: The H330 variant includes integrated RAID support and a smaller footprint, making it ideal for space-constrained environments. The standard M640 lacks RAID integration and is slightly larger.

Q: Can I upgrade the firmware on a used Dell PowerEdge M640 H330 Mini Blade Chassis?
A: Yes, but only if the firmware is at least version 1.8.0. Firmware updates beyond 2.1.0 may not be supported on units older than 2016. Always verify the firmware version before purchase.
