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 product lines dominate the x86 server market with a combined 50%+ market share. 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) | DL380a 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 |
| License Cost | ~$200-350 one-time | ~$200-400 one-time |
| Mobile App | OpenManage Mobile | HPE iLO Mobile |
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 |
| PERC H755N | Smart Array P816i-a | SAS 12Gbps | 4GB |
Dell PERC controllers and HP Smart Array controllers perform similarly. The key difference: Dell uses a universal backplane and the RAID controller sits in a dedicated mini-mono slot, while HP integrates the base controller onto the motherboard with the option to add a PCIe controller.
Parts Availability and Pricing (2026)
This is where the real difference emerges for budget-conscious buyers.
| Component | Dell PowerEdge | HP ProLiant |
|---|---|---|
| Power Supplies | Widely available, $25-60 | Available, $30-80 |
| Drive Caddies | Universal across gens, $5-8 | Generation-specific, $5-10 |
| RAM (32GB DDR4) | $30-50 | $30-50 |
| RAID Controllers | $40-120 | $50-150 |
| Motherboards | $80-250 | $100-300 |
| Heatsinks | $10-25 | $15-30 |
Dell generally has lower parts costs because their component ecosystem is more standardized across generations. HP parts tend to be more generation-specific.
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
- You run VMware (Dell owns VMware licensing advantages)
- 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
For refurbished servers: Dell PowerEdge wins on price and parts availability. The R720, R730, and R740 have the largest secondary market of any server platform. HP ProLiant Gen8 and Gen9 are also excellent values but typically cost 10-20% more for equivalent specs.
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.
