The Dell PowerEdge XR7620, XR8610t, and XR8620t are rugged edge servers designed for high-performance computing in harsh environments. Choosing between them depends on workload demands, chassis compatibility, and desired scalability at the edge.
What are the key differences between the Dell PowerEdge XR7620, XR8610t, and XR8620t?
The XR7620 is a 2U, dual-socket rack server with support for two Intel Xeon processors, extensive memory (up to 2 TB DDR5), GPU acceleration, and five PCIe slots. In contrast, the XR8610t is a 1U half-width, single-socket server sled for the XR8000 chassis with eight DDR5 DIMM slots and one PCIe slot, ideal for dense compute. The XR8620t is a 2U half-width, single-socket sled with more PCIe slots (three) and similar memory specs to the XR8610t, suited for diverse, higher-capacity workloads.
How do these servers support edge computing in harsh environments?
All three models are ruggedized with MIL-810H and NEBS Level 3 certifications, enabling operation in extreme temperatures (-5°C to 55°C), shock, and vibration. The XR7620 features a self-contained chassis with optional dust filters and security bezels, while the XR8610t and XR8620t are sleds requiring installation in a PowerEdge XR8000 chassis, tailored for various edge scenarios like industrial automation, AI inferencing, and video analytics.
Which processor and memory configurations do these servers offer?
The XR7620 supports dual 4th or 5th Gen Intel Xeon Scalable processors, each up to 32 cores, with 16 DDR5 DIMM slots supporting up to 2 TB memory. The XR8610t and XR8620t support a single 4th or 5th Gen Intel Xeon Scalable processor, also up to 32 cores, with eight DDR5 DIMM slots maxing out at 512 GB. All support high-speed DDR5 memory with ECC for reliability.
What storage and expansion options are available for these servers?
The XR7620 provides up to four 2.5″ SAS/SATA/NVMe drives or eight E3.S NVMe drives, alongside five PCIe Gen 5 slots for expansion and GPU accelerators supporting up to two double-wide GPUs. The XR8610t includes BOSS-N1 with dual M.2 NVMe SSDs and one PCIe slot, whereas the XR8620t offers multiple M.2 NVMe configurations with three PCIe slots, allowing for more I/O and storage flexibility within the XR8000 chassis.
Why choose the XR7620 over the XR8610t and XR8620t?
Choose the XR7620 when you need the highest performance edge server in a compact, self-contained chassis with dual processors, ample memory capacity, and GPU acceleration support. It is optimal for complex AI and machine learning applications demanding top compute power and low latency, without relying on an external chassis.
How do the XR8610t and XR8620t enable flexibility and scalability?
As half-width server sleds designed for the XR8000 multi-node chassis, the XR8610t and XR8620t allow mixing different compute and acceleration nodes for scalability. The XR8610t suits dense compute needs with fewer PCIe slots, while the XR8620t offers enhanced I/O with additional PCIe slots, making them perfect for growing edge workloads in telecom, manufacturing, and military sectors.
What are the security and manageability features of these servers?
All models include Dell’s iDRAC9 with features like secure boot, cryptographically signed firmware, system lockdown (with Enterprise or Datacenter licenses), TPM 2.0 certified hardware security, and silicon root of trust. They support OpenManage software for streamlined lifecycle management and cloud integration, ensuring reliability and secure operation at the edge.
Which industries and use cases benefit most from each server model?
-
XR7620: Ideal for industrial automation, AI inferencing, video analytics, machine learning, and point-of-sale analytics requiring powerful, low-latency compute.
-
XR8610t: Perfect for telecommunications edge workloads like centralized/distributed RAN, manufacturing, and military that require dense, scalable compute.
-
XR8620t: Best for diverse and I/O-intensive edge workloads including AI/ML, network edge, and field operations needing greater PCIe expansion.
