With robust specs like these, you can tackle demanding workloads with ease. Whether you need to crunch big data, power clinical systems, or run private clouds, the R740 delivers. The dual CPU and big memory capabilities readily support large in-memory databases for analytics.

And if your storage appetite grows over time? The R740XD model boosts drive bays to 32 plus up to 24 high speed NVMe SSDs.

Comparing the Dell R740 vs R740XD Servers

The standard R740 fits most workloads. But video rendering farms, data warehouses, financial risk modeling, and genomics applications need vast pools exceeding even 128TB. This is where the R740XD‘s added capacity comes in.

Dell PowerEdge R740

  • 16x 2.5" front drive bays
  • Up to 4x NVMe drives internally in PCIe slots
  • Great for typical business apps
  • More affordable starting price

Dell PowerEdge R740XD

  • 24x front 2.5" drive bays
  • 8x internal 3.5" drive bays
  • Up to 332TB+ with disk dense enclosures
  • Optimized for mega-storage needs
  • Premium pricing but excellent $/TB ratio

Aside from storage limits, the two models share identical components from memory, CPUs and PCIe slots to PSUs. Choose the “XD” if you foresee needing 50TB+ now or on a growth trajectory hitting that in the next 2-3 years.

Dell R740 Server Networking Capabilities

The R740 gives robust options to hook into high-speed networks:

  • Embedded NIC – Dual 1GbE Broadcom 5720 ports standard
  • Mezzanine – OCP 2.0 cards give 2 x 10GbE or 25GbE flexibility
  • Network Daughter Card – Quad 1GbE to dual 25GbE to 100GbE connect at bandwidth needed

This versatility lets you scale connectivity from 1Gb all the way to 100GbE in a single R740 as demands grow. Dell Networking switches like the S4148F-ON support matching 100Gbps ports to build a high performance rack.

Dell R740 Remote Management, Automation & Security

Efficiently managing servers saves IT teams hours of routine upkeep. The R740 offers:

  • OpenManage Enterprise – Monitor health/utilization, update firmware, scripts using a modern UI
  • OpenManage Mobile – Remotely manage single or multiple servers via Android/iOS app
  • iDRAC9 with Lifecycle Controller – Quickly configure hardware, OS, drivers without visiting data center
  • Redfish REST API – Ideal for cloud automation with Ansible, Terraform, Puppet, Chef, Python
  • Secure NFC – Pair mobile device by simply tapping it to the R740’s built-in NFC label

These tools combined with cyber resilience features create a hardened server platform. For example:

  • Hardware root of trust – Unique RSA key burnt into the server during manufacturing

  • Signed firmware updates – Ensures authenticity and prevents compromises

  • System lockdown mode – Prevents change to firmware versions or configurations

  • Cryptographically signed components – Detect tampering of fans, memory modules etc

Threat detection, secure boot, BIOS authentication lock unauthorized changes while still enabling remote management. For heavily regulated environments in finance, healthcare, retail and government – such security is mandatory.

Ideal Use Cases and Benchmarks for the Dell R740

With excellent benchmarks across transactional, analytics and HPC workloads the R740 readily handles:

Virtual Desktop Infrastructure (VDI)

  • Top VDImark score of 14.6 buds/$
  • Host 50+ Horizon virtual desktops per server

With such versatility, the R740 runs traditional business applications, CAD engineering tools, scientific modeling software, genomics analysis and electronic health record systems with ample headroom.

Dell R740 Server Configurations & Pricing

The R740 list pricing starts around $3,000 but realistic mid-range configs land between $6,000 – $12,000 depending on:

  • CPUs – Single Silver or dual Gold Xeons
  • RAM – 128GB to 768GB RAM
  • Storage – 8 to 10 SATA SSDs + 4 to 6 SAS HDDs
  • Network – 10GbE to 25GbE mezzanine cards
  • Graphics – Single pass-through GPU card
  • RAID Card – H740P w/ battery backup
  • Gold Support – 5 year ProSupport Plus 24×7

On the refurbished/used market, prices range widely but expect 50-70% discounts from list. For example:

$18,000 List Config Discounted Refurb Price
Dual Xeon Gold 5120 CPUs $5,400
192GB (12x16GB) RAM
8x 1.6TB SAS 12G HDDs
8x 960GB SATA SSDs
Qlogic FastLinQ 10/25GbE Card
H740P RAID Card w/ FBWC
iDRAC Enterprise License
5 Year Warranty

When evaluating used R740 pricing, factor in capacity for growth. Units with dual 1100W PSUs, all RAM slots populated, most drive bays filled, and extra PCIe risers cost more but offer easy scaling.

Pros and Cons: Buying New vs Refurbished

Buying new advantages:

  • Fully customize every component
  • Warranty covers full 5+ years
  • Latest BIOS, firmware revisions
  • Finance 100% using Dell loan

Refurbishment benefits:

  • 50-70% cheaper for mid-high specs
  • Components burned-in and tested by Dell
  • Warranty still 3-5 years via Dell Outlet
  • Helps sustainability reusing servers

If budget allows, purchasing new lets you tailor every aspect – from CPUs and RAM to drives, RAID cards etc. This gets you the utmost in performance. Just be wary of overspeccing components which go unused wasting money.

For most environments, a certified refurbished R740 with balanced components meets needs at considerable savings. Expect some visual scratches but operationally it functions like new.

Final Thoughts on the Dell PowerEdge R740

Still producing excellent benchmark results 6 years post-launch with the latest Intel CPUs, the R740 maintains relevance even as Dell introduces next-gen PowerEdge servers. Its optimal mix of speed, expansion and dependability make it a versatile mainstay in data centers of all sizes.

If you need to drive SQL, virtualization, modern distributed apps or intensive simulations – I strongly recommend evaluating the R740, especially as easy scalability is key to your growth plans. Its dual Xeon six-channel architecture readily supports memory-hungry processes with ample DDR4. You can tune storage using all-flash or a smart HDD/SSD hybrid tiering approach balancing IOPS performance, low latency and affordability.

While buying brand new allows fully customizing every last component, explore certified refurbished R740 servers to maximize value. You still get enterprise quality and warranty protection at 30-50% cost savings. This lets SMBs tap true server-grade infrastructure perhaps for the first time.

For medium to large organizations, the R740 easily integrates with existing management platforms. And it gives older generation servers a major kick in responsiveness when running parallel workloads. The R740 is hands down the most balanced, highest value server on the market with staying power.
