Frequently Asked Questions

What is the difference between PERC H755 and PERC H755n?

The PERC H755 includes a supercapacitor-backed cache for write-back caching, while the PERC H755n (9K2C2) uses NV cache without the supercapacitor — making it suitable for environments where write-back cache protection is handled differently.

What RAID levels does the Dell PERC H755n support?

The Dell PERC H755n supports RAID levels 0, 1, 5, 6, 10, 50, and 60 for comprehensive data protection and performance configurations.

Is the PERC H755n compatible with VMware ESXi?

Yes, the Dell PERC H755n is supported by VMware ESXi with Dell-provided drivers, making it suitable for virtualization host storage in Dell PowerEdge environments.
