Dell PowerEdge vs HP ProLiant — Which Server Should You Buy in 2026?
Head-to-head comparison of Dell PowerEdge and HP ProLiant servers. R750 vs DL380, iDRAC vs iLO, pricing, parts availability, and which brand wins for each use case.
Dell PowerEdge vs HP ProLiant — The Enterprise Server Showdown
Choosing between Dell PowerEdge and HP ProLiant is the most common decision in enterprise IT purchasing. Both use identical Intel Xeon or AMD EPYC processors, support the same RAM and storage standards, and run every major operating system and hypervisor.
So what actually differentiates them? Management software, parts ecosystem, pricing, and support. This guide breaks down every factor to help you choose.
Generation Comparison Table
| Dell PowerEdge | HP ProLiant | CPU Platform | RAM | Release |
|---|---|---|---|---|
| R760 (16th Gen) | DL380 Gen11 | Intel Xeon 4th/5th Gen | DDR5 | 2023-2024 |
| R750 (15th Gen) | DL380 Gen10 Plus | Intel Xeon 3rd Gen | DDR4 | 2021-2022 |
| R740 (14th Gen) | DL380 Gen10 | Intel Xeon Scalable 1st/2nd Gen | DDR4 | 2017-2020 |
| R730 (13th Gen) | DL380 Gen9 | Intel Xeon E5-2600 v3/v4 | DDR4 | 2014-2017 |
| R720 (12th Gen) | DL380p Gen8 | Intel Xeon E5-2600 v1/v2 | DDR3 | 2012-2014 |
Remote Management — iDRAC vs iLO
Both Dell and HP include out-of-band management controllers that let you monitor, configure, and troubleshoot servers remotely — even when the OS is down.
| Feature | Dell iDRAC9 | HP iLO 5 |
|---|---|---|
| HTML5 Console | Yes | Yes |
| Virtual Media | Yes (ISO mount) | Yes (ISO mount) |
| Power Management | Full (on/off/cycle/cap) | Full (on/off/cycle/cap) |
| Hardware Monitoring | Temperatures, fans, PSU, drives | Temperatures, fans, PSU, drives |
| Firmware Update | Yes (direct or repo) | Yes (SPP or direct) |
| REST API | Redfish API | Redfish API |
| License Required? | iDRAC Express (free) covers basics; Enterprise for console | iLO Standard (free) covers basics; Advanced for console |
Both platforms are excellent for remote management. iDRAC has a slight edge in BIOS configuration via web UI, while iLO has better integration with HPE OneView for large fleet management.
RAID Controllers
| Dell | HP | Interface | Cache |
|---|---|---|---|
| PERC H730P Mini | Smart Array P440ar | SAS 12Gbps | 2GB |
| PERC H740P | Smart Array E208i-p | SAS 12Gbps | 8GB (H740P) / none (E208i-p) |
| PERC H755N | Smart Array P816i-a | NVMe PCIe Gen4 (H755N) / SAS 12Gbps (P816i-a) | 8GB (H755N) / 4GB (P816i-a) |
Dell PERC controllers and HP Smart Array controllers perform similarly. Both vendors offer controllers that sit in a dedicated storage-controller slot (Dell's mini-mono PERC; HP's P440ar and the modular "-a" Smart Array cards) as well as standard PCIe plug-in controllers.
Which Should You Buy?
Choose Dell PowerEdge if:
- You want the lowest total cost of ownership
- Parts standardization across generations matters
- You prefer iDRAC for remote management
- Budget is the primary concern
Choose HP ProLiant if:
- You have an existing HP infrastructure
- HPE OneView fleet management is important
- You need the DL560/DL580 4-socket platform
- Your team is trained on HP tools
- Enterprise support contracts are a priority
Key Takeaway: There is no wrong choice between Dell and HP. Both are enterprise-grade platforms that will serve you well for years. The decision often comes down to existing infrastructure, team familiarity, and parts pricing.
