The Dell PowerEdge R710 ranks among the most legendary rackmount servers of the past decade, with hundreds of thousands of units deployed globally since its 2009 debut. As we enter 2023, a devoted community of IT pros, small business owners, developers and hobbyists continue to rely on the R710 for all kinds of workloads. Its unique balance of capability, flexibility and value perpetuate the dominance of this platform.
Let‘s delve into every aspect, component, feature and capability that makes the R710 such an enduring technological and cultural phenomenon all these years! This guide assumes a mildly technical reader who is keen on advancing their hands-on sysadmin skills.
Product Origin and Evolution
Before exploring the R710 itself, it helps to understand the rich history of Dell‘s flagship PowerEdge lineup that brought us to this point over three decades.
Back in the early 1990‘s, Dell pioneered several innovations to manufacture reliable servers en masse for the rapidly growing client-server and early internet era. The PowerEdge family combines rack density, redundancy features and a modular architecture suited to business critical roles.
Regular tick-tock updates iterated on CPU architecture, memory technology, storage interconnects, virtualization capabilities and manageability with each generation – 2000, 3000, 5000, 6000 etc. The 700-series sits in the middle tiers targeting SME and remote office applications rather than high-end enterprise use cases.
The R710 thus benefits from decades of battle-hardened designs and learnings in areas like:
- Efficient airflow and cooling
- Redundant, hotswap components
- Security, monitoring and automation
- OS and hypervisor support matrices
So rather than a wholly new model, it represents an optimized refresh of existing technologies – much like the "tock" in Intel‘s famous tick-tock silicon strategy.
Positioning Within Dell‘s 2009 Portfolio
The PowerEdge label adorns an extensive range of tower, rack and blade form factors aimed at different needs. Before committing to the R710, it is instructive to see how it is positioned amongst its R-series siblings:
PowerEdge Line in 2009
The R900 and M-series sit above it targeting enterprise customers wanting highest scale and performance. The R610 provides a slightly more compact 1U sibling for lighter needs. The R710 hit the sweet spot between both – dense yet flexible enough for mid-market roles.
For SMBs or Remote offices, the T710 tower corresponds closely from a specifications standpoint, just in a more office friendly chassis.

When configured with dual hex-core CPUs, hyperthreading enabled, and maxed out RAM – the R710 easily hosts:
- 30+ Windows/Linux VMs
- Or 50 containerized microservices
- Hypervisor of choice vSphere/XenServer/Hyper-V
Ideal for self-hosted virtual labs, dev environments and production workloads alike.
This data should help better qualify if the R710 packs enough punch for your applications vs alternatives. Of course, care should be taken not to severely overprovision VMs beyond host capacities.
Operating System Compatibility
The software support story is equally versatile for the R710 thirteen years from launch. Broad OS and hypervisor support continues across Windows and Linux distributions – thanks to its widespread popularity and continuing driver updates.
Let‘s enumerate the leading platforms verified to work properly:
Windows
- Windows Server 2022
- Windows Server 2019 and 2016
- Windows Server 2012, 2008 R2
Linux Distributions

Backwards support is usually tied to extended Long Term Support releases that share a common kernel version. Debian 11, Oracle Linux, and RancherOS also work well.
So most common environments enjoy years of support ahead – ample buffer for incremental upgrades.
Expansion Potential
Can such an old server stay relevant in the roaring 2020s? Absolutely – thanks to incredible upgrade flexibility across every dimension.
Let‘s consider viable upgrade paths on four key fronts:
1. Additional RAM
- Current max : 288GB (18x 16GB DIMMs)
- Potential max: 576GB (36x 16GB RDIMMs)
2. Higher Efficiency CPUs
- Current config: Xeon L5520 65W quads
- Potential options: X5690 130W 6-core hexa‘s
3. Increased Storage
- Currently: 8x 1TB HDDs = 8 TB
- Potential max: 8x 8TB SSDs = 64 TB
4. Faster Networking
- Embedded quad port NICs ➔ Dual/Quad 10Gbe NICs
- Dramatically boost IO
This illustrates a 4-10X headroom across critical subsystems to adopt emerging technologies! You won‘t face forced end-of-life and forklift upgrades for several more years.
Real World Value Economics
The roughly $1500-2000 investment into a refurbished R710 with strong specifications also contrasts very well against other alternatives:
Modern Rackmounts
- Dell R750 starts around $5000
- Cisco C240 M5 around $2500
- Lenovo ThinkSystem SR650 from $3000
Cloud Instance Pricing
- AWS m5.2xlarge instance = $340/month
- Digital Ocean Premium droplet = $80/month
- Linode Dedicated vCPU instance = $1000/month
Clearly neither cloud services nor new hardware can compete on TCO metrics. This makes R710 very attractive for self-hosted apps, mass experimentation, homelabs. Where failure is an option – minimizing sunk cost into infrastructure lets you take more bold risks!
Managed Service Providers also stock up on these servers to pass on savings from economies of scale + aged hardware to clients with modest hosting needs.

Handling Firmware and Software Updates
Once you have your own R710 – next task is hammering it into shape software wise!
Critical Components
- iDrac Remote Access Controller
- RAID Controller Firmware
- BIOS
- NIC Cards
- Backplanes
- Expanders
Safest Approach
Establish remote connectivity over iDrac interface first. This allows remote management capabilities independent of OS status. Next check serverspecs.dell.com for certified update levels recommended by Dell.
Incrementally flash only those subsystems needing updates in sequence. Always have console access to rollback changes should issues crop up. Don‘t blindly update to latest as dependencies might break things!
Resources
Collated firmware binaries are available from Boards.ie member GraniteGeek. I suggest referring to his tips as well when performing updates.
Finessing Real World Operation
Delving deeper – day-to-day care and feeding of your R710 can also be enhanced by adopting operational best practices:
- Toggle BIOS from Complete to Thorough modes
- Tweak paging file strategy for heavy memory use
- Optimize NIC interrupt handling
- Bind virtual NICs to isolated physical cores
- Pin interrupt costly processes likewise
- Limit memory overprovisioning in virtualization
- NUMA alignment for VMs in hypervisors
- Schedule scrubbing, patrol reads for storage health
While beyond our current discussion scope here, entire books could be written about optimizing real-world R710 deployments!
So bookmark resources like the SysAdmin Handbook or Julian Dunn‘s Blog for a headstart.
Finding Your First Projects
Freshly minted R710 owners often struggle for ideas to break-in their new toy. Here are handy starter projects:
1. Virtualization Host
Create separate VM guests for Plex, BlueIris and Home Assistant. Add PiHole or pfSense virtual appliances. Switch dockers to VMs for improved reliability.
2. Self-hosted Platform
Stand up an app stack like LAMP/LEMP to figure basic Linux systems administration. Sandbox nextcloud, OnlyOffice and Gitlab to better grasp application dependencies.
3. Kubernetes Cluster
Create a simple cluster for containerized microservices across film library, password manager, media automation workflows – tightened integrations!
4. Storage Projects
Enable deduplication for backups. Or create a Ceph cluster across flash drives for lightning fast shared storage. Learn ZFS nuances.
5. Media Center
Direct attach USB 3 ports to a hardware transcoding card like Intel QuickSync. Or pass an old video card to Blue Iris/Plex VMs if your CPUs choke during 4K transcodes rather than building a dedicated NAS.
6. Gaming Sessions
If newer GPUs are hard to source or incredibly expensive, pass a dated Quadro / Radeon card to Windows 10 VMs. Spin up gaming instances as needed for some retro fun!
Possibilities are endless – limited chiefly by your passion, creativity and Unix skills!
Downsides to Factor In
For fairness, let‘s also acknowledge where the R710 shows its age and technology limitations vs modern platforms:
- Individual cores are markedly weaker than latest Intel chips
- Overall throughput capped vs mainstream socketed Epycs
- Lower memory clocks compared to DDR4 limits bandwidth
- PCIe gen 2 slots constrained by 5GT/s transfer rates
- 4x onboard 1Gbps NICs seem pedestrian now
- CPUs often sip more power for each unit of computation
- Larger physical footprint – not great for homelabs
- Idrac 6 UI less polished than latest generations
- Noisy delta fans necessitate replacements
So temper expectations when sizing for heavy transcoding, ML inferencing type emerging workloads. Plan ahead for where bottlenecks could pop up.
The Last Word
I hope this rather exhaustive deep dive has armed you to make an informed adoption decision around the Dell R710 server as we charge ahead in 2023.
Clearly, the R710 is no spring chicken anymore – some wrinkles exist. However, a versatile architecture, strong community and enduring platform support offset that to a degree. Upgrades can prevent early obsolescence for several more years in non-critical roles.
Undoubtedly, if your applications demand the highest cores, memory bandwidth or Gen 4 PCIe slots – newer hardware provides better value all round. The sweet spot for R710‘s remains smaller workloads from smaller businesses that prioritize risks and experiments over scale.
So seek out one such server gathering dust to nourish your next brave dream !!
