Comparing positioning and technical features

Both the Dell PowerEdge R760 and R760xa servers are based on the 4th generation Intel Xeon Scalable CPUs and are members of the 16th generation of Dell PowerEdge servers. The the R760xa is a server designed for high workloads and  high performance computing but R760 is a more versatile solution..

1. CPU:

• Dell PowerEdge R760: Offers a wide selection of models, ranging from entry-level to high-performance, high-core alternatives, that support up to two 4th Gen Intel Xeon Scalable CPUs. It is ideal for a variety of workloads, including virtualization, databases, business applications, and more.

• Dell PowerEdge R760xa: Furthermore supports up to two Intel Xeon Scalable processors from the fourth generation. However, because the R760xa is intended for more demanding computational activities, it is frequently equipped with high-performance CPUs. Although the processor choices might be comparable, the R760xa prioritizes optimizing CPU performance in order to support accelerators.

2. RAM (memory):

• Dell PowerEdge R760: With 32 DIMM slots, it can handle DDR5 DIMMs up to 8TB in size and speeds up to 4800 MT/s. This delivers a large amount of memory bandwidth, which is enough for the majority of common server workloads.

• Dell PowerEdge R760xa: Also features 32 DIMM slots that can handle up to 8 TB of DDR5 DIMMs at speeds of up to 4800 MT/s. The R760 has the same memory capacity and speed. The main distinction is not the memory itself, but rather how the server utilizes the memory to back the accelerators.

3. Support for accelerators (GPU/FPGA):

• Dell PowerEdge R760: Only supports a small number of GPUs, usually a maximum of two full-size or four half-size GPUs. Although it may be used for VDI or simple graphics tasks, it is not designed for high-performance GPU applications.

• Dell PowerEdge R760xa: The R760xa is designed to offer the best accelerator support possible. It can support up to eight single-width GPUs or four double-width full-width GPUs, like the NVIDIA A100, H100, or AMD Instinct MI200. Because of this, it's a great choice for:

• Machine Learning (ML) and Artificial Intelligence (AI): Teaching and deducing models.

• High-performance computing (HPC): Simulations, engineering analysis, and scientific calculations.

• High-density virtual desktops (VDI) with GPUs: Expert graphics programs.

4. Disk subsystem (Storage):

• Dell PowerEdge R760: Provides versatility in storage setups, such as:

• Front bays: as many as 16 NVMe/SAS/SATA drives measuring 2.5 inches by 16 inches, or as many as 8 SAS/SATA drives measuring 3.5 inches by 16 inches.

• Rear bays: may be set up to provide more storage.

• Enables booting the OS from an internal M.2 SSD. Because of its versatility, the R760 can be used for a variety of applications, including data storage and retrieval.

• Dell PowerEdge R760xa: To maximize room for the GPU and ensure adequate cooling, the disk subsystem setup has been modified somewhat. The R760xa usually has less front storage bays, but it still has plenty for tasks that are speed-intensive.

• Front bays: typically between 8 x 2.5" NVMe/SAS/SATA or between 4 x 3.5" SAS/SATA (the number may vary depending on the GPU setup).

• Rear bays: may be used for extra storage.

• Support for booting the operating system from internal M.2 SSDs. The R760xa may have a little less storage space than the highest-end R760 model, but it still has the NVMe storage that is necessary for speedier workloads.

5. Expansion slots (PCIe):

• Dell PowerEdge R760: Offers a large number of PCIe Gen5 slots for network cards, storage cards, and other expansion adapters.The number of slots may change according to the riser setup, .

• Dell PowerEdge R760xa: Has more PCIe Gen5 slots, which are made for supporting several GPUs. The R760xa's PCIe slot arrangement is designed to maximize GPU density, which is a crucial aspect of the device.

6. Network

• Dell PowerEdge R760 & R760xa: Both servers have PCIe slots and OCP 3.0 cards for a variety of network connection choices. Depending on the adapters chosen, the choices may include 1GbE, 10GbE, 25GbE, 40GbE, 100GbE, or even faster connections. The selection of network adapters will be determined by the demands of the particular workload.

7. Management and Responsibilities:

•The management capabilities are the same for both models.Both these servers use the Dell iDRAC9 management platform with Lifecycle Controller forn server deployment, updates, monitoring, and maintenance. The models also support integration with third-party platforms and Dell OpenManage Enterprise management consoles.

8. Power and cooling:

• Dell PowerEdge R760: Provides a selection of redundant power supply unit (PSU) choices with varying wattages designed for common server setups. Under normal workloads, the cooling system is intended to effectively remove heat from CPUs, memory, and other parts.

• Dell PowerEdge R760xa: Includes an innovative cooling system and more potent power supplies, both of which are made to handle the excessive heat output and power usage of high-performance CPUs and GPUs. It is essential to cool the R760xa in order to maintain consistent performance under peak accelerator loads.

9. Form factor:

• Dell PowerEdge R760 and R760xa: Both are 2U rack servers. However, the internal design of the R760xa is different for GPU placement, which may have an impact on the availability of specific parts and storage setup choices.

Positioning:

Dell PowerEdge R760: An adaptable server for a broad variety of tasks. Perfect for:

• Virtualization

• Databases

• Business software

• Cloud-based infrastructure

• Overall server infrastructure

Dell PowerEdge R760xa: A server designed for high-speed computing. Positioned for:

• Machine Learning (ML) and Artificial Intelligence (AI)

• High-performance computing (HPC)

• Virtual desktops (VDIs) with graphics acceleration

• Workloads that demand a lot of GPU/FPGA processing power

In summary:

Which model you choose between the Dell PowerEdge R760 and R760xa will depend on your individual requirements.

• If you don't intend to utilize a lot of GPUs or intensive accelerated computing and need a dependable and adaptable server for a variety of common workloads, pick the R760.

• Select the R760xa if your workloads need a lot of GPU/FPGA compute capacity, like for AI/ML, HPC, or graphics-accelerated VDI. The R760xa is a specialized server designed to deliver the best possible performance in these challenging situations.
