Pros & Cons
👍 Pros
- Dual E5-4650 v2 processors deliver 20 physical cores / 40 threads at 2.4GHz base — sufficient parallel processing density for mid-tier virtualization hosts running dozens of concurrent VMs.
- 40 logical threads from two E5-4650 v2 sockets supports dense VMware/Hyper-V virtualization that single-socket servers cannot match
- 128GB DDR3 with 48-DIMM expansion path provides substantial working memory for in-memory databases and large VM guest allocations
- 128GB DDR3 RAM provides significant working memory for in-memory database workloads and high-VM-density virtualization without immediate memory expansion costs.
- The H710 512MB RAID controller with hardware RAID support protects data integrity while the 512MB cache buffer meaningfully improves write throughput versus software RAID alternatives.
- Tiered storage combining SATA SSDs and SAS HDDs allows fast boot/OS volumes on SSD with bulk data on SAS without additional hardware
- H710 controller with 512MB battery-backed cache protects write operations during power interruptions in production environments
- The 16 x 2.5-inch hot-swap bay chassis supports live drive replacement without taking the server offline — a critical operational feature for production workloads requiring high availability.
- The mixed SSD/SAS storage layout (2x 960GB SSD + 6x 900GB SAS) enables tiered storage configurations — SSDs for OS and hot data, SAS spindles for capacity — maximizing both performance and cost-per-gigabyte efficiency.
- 16-bay 2.5-inch backplane provides significant storage density for a 2U chassis footprint
👎 Cons
- DDR3 memory is two generations behind current DDR5 server standards, meaning memory bandwidth is a ceiling on workloads sensitive to memory throughput — relevant for high-frequency trading, large-scale analytics, or memory-intensive HPC applications.
- E5-4650 v2 is a 2013-era processor family — IPC (instructions per clock) performance is well behind current-generation Xeon Scalable processors, which matters for single-threaded application performance
- DDR3 memory is not compatible with DDR4 expansion modules, limiting upgrade paths to a pool of older, increasingly hard-to-source DIMM stock
- The E5-4650 v2 Ivy Bridge-EP architecture lacks AVX-512 instruction support and modern security mitigations (Spectre/Meltdown patches impose measurable performance penalties on this generation).
- As a renewed 2U rack server, the R820 draws significant power under load — dual E5-4650 v2 CPUs can approach 250W TDP combined, plus drives and RAID controller, making power and cooling costs a real operational consideration.
- As a renewed enterprise server, warranty terms and remaining serviceable life are less predictable than a new purchase with full OEM support
- The R820 chassis depth (~29 inches) may not fit short or mid-depth rack enclosures without extender rails
- Renewed status means the warranty and remaining service life depend on seller certification level — enterprise workloads requiring guaranteed SLA uptime should verify Dell ProSupport availability before deployment.
- The R820's E5-4600 socket is end-of-life from an upgrade path perspective; CPU, memory, and platform upgrades are not possible beyond the maximum spec the R820 platform supports.
- Power consumption on dual Xeon E5-4650 v2 systems is substantial — TDP is 130W per socket before memory, storage, and fans are factored in, resulting in meaningful data center power and cooling costs
Frequently Asked Questions
What is the total CPU core count and clock speed profile of this R820 configuration?
The R820 ships with two Intel Xeon E5-4650 v2 processors, each with 10 cores at a 2.4GHz base clock with Turbo Boost headroom. Combined, that is 20 physical cores and 40 logical threads via Hyper-Threading — a meaningful parallel processing capacity for virtualization, database, or batch processing workloads.
What is the total raw compute capacity of this server's two Xeon E5-4650 v2 processors?
Each E5-4650 v2 is a 10-core chip at 2.4GHz base with Hyper-Threading, giving 20 physical cores and 40 logical threads across both sockets. That thread count supports heavy virtualization workloads, multi-tenant databases, and parallel processing tasks that would saturate a dual-socket mainstream Xeon configuration.
What storage configuration does this server ship with?
The server includes two 960GB SATA SSDs and six new 900GB SAS HDDs (totaling approximately 7.32TB combined raw storage). The H710 RAID controller with 512MB cache manages both SSD and SAS pools, allowing tiered or RAID-protected configurations.
What is the memory configuration, and is it ECC?
The system ships with 128GB of DDR3 RAM. Server-class Xeon E5-4600 v2 platforms use ECC (Error-Correcting Code) memory as standard — ECC status should be confirmed with the seller, but the R820 platform is designed to operate exclusively with ECC-registered DDR3 DIMMs.
What does the H710 512MB controller support, and does it affect which RAID levels are available?
The H710 512MB RAID controller supports RAID levels 0, 1, 5, 6, 10, 50, and 60. The 512MB cache improves write performance significantly versus a no-cache or small-cache RAID controller. A battery-backed unit (BBU) status should be confirmed with the seller, as the BBU enables write-back caching.
What memory capacity does this server support beyond the included 128GB?
The R820 supports up to 1.5TB of DDR3 RAM across its 48 DIMM slots (24 per socket). The current 128GB configuration leaves substantial headroom for expansion if future workloads require more memory-resident data.
Is this server rack-mountable, and what rack depth is required?
The PowerEdge R820 is a standard 2U rack server designed for 19-inch server racks. Its depth is substantial — Dell R820 chassis are approximately 29 inches deep — so rack depth should be confirmed before purchasing for shallow or mid-depth racks.
How many drive bays does the R820 have, and what drives are currently installed?
The R820 chassis supports 16 x 2.5-inch hot-swap drive bays. The listed configuration includes 2x 960GB SATA SSD and 6x NEW 900GB SAS HDDs — totaling approximately 7.32TB of raw storage across the installed drives.
What are the realistic workload use cases for this server in 2024?
The R820 with 20 cores and 128GB RAM is well-suited for virtualization hosts (VMware ESXi, Proxmox), database servers (MSSQL, PostgreSQL), development environments, and private cloud infrastructure. As a renewed platform, it offers enterprise-grade redundancy (dual PSU, ECC RAM, hot-swap drives) at significantly reduced capital cost versus current-generation hardware.
What does 'renewed' mean for this server, and what warranty applies?
Renewed indicates the server has been inspected and tested but is not factory new. Individual seller warranties vary — this listing should be checked for specific coverage terms. Enterprise servers often have Dell ProSupport options available separately if long-term coverage is needed.
