ASUS ESC4000-G4S 2U Accelerator Server Chassis With 16 Dimms AND 8 Hot-swap 2.5 Stora

ASUS ESC4000-G4S 2U Dual-Processor GPU Accelerator Server

Overview

The ASUS ESC4000-G4S is a 2U rack-mount accelerator server built around the dual Intel® Xeon® Scalable processor platform — designed for compute-dense workloads where you need serious GPU throughput and large memory headroom in a standard rack footprint. Anchored by the Intel® C621 chipset and LGA 3647 (Socket P) architecture, the ESC4000-G4S supports two processors simultaneously, giving you the core count and memory bandwidth that AI inference, video analytics at scale, and high-channel NVR workloads demand. At 90.87 lb and 10.24 inches tall (2U), this is a dense system — plan your rack weight distribution before ordering.

Key Features

• Dual Intel® Xeon® Scalable Processors (LGA 3647): Two Socket P (LGA 3647) processor slots let you deploy two Intel® Xeon® Scalable CPUs, doubling core count and memory channels versus a single-socket alternative. For video analytics workloads running parallel deep-learning inference streams, the NUMA topology matters — workload pinning across both sockets maximizes throughput.
• 16 DIMM Slots with Up to 2 TB DDR4 Memory: Sixteen DDR4-SDRAM DIMM slots accept modules from 4 GB up to 64 GB each, scaling to 2 TB total system memory. That ceiling matters when you are running in-memory databases, large VMS recording buffers, or multiple GPU-accelerated analytics engines simultaneously — you will not hit a memory wall that forces you to swap workloads out to storage.
• 8 Hot-Swap 2.5" Storage Bays: All eight drive bays are hot-swappable 2.5" slots, which means you can pull and replace a failed drive without taking the server offline. In 24/7 surveillance recording environments, this directly translates to zero-downtime storage maintenance — no recording gap during a disk failure event.
• M.2 Storage Interface: An M.2 interface provides a high-speed slot for OS boot drives or cache tiers, keeping your SAS/SATA bays free for bulk video storage and freeing your hot-swap bays for surveillance HDDs or SSDs where they deliver the most value.
• Intel® I350-AM2 Dual-Port Gigabit Ethernet: The onboard Intel® I350-AM2 controller delivers two ports of 10/100/1000 Mbit/s Ethernet. For camera-facing recording servers, two NICs let you separate management traffic from the camera network — a clean topology that simplifies firewall rules and limits broadcast domains.
• Aspeed AST2500 IPMI / BMC Graphics: The 64 MB Aspeed AST2500 onboard graphics controller provides IPMI-based out-of-band management. Administrators can access the system console remotely without a dedicated GPU in a management slot — reducing complexity in headless data center or IDF deployments.
• Intel® C621 Chipset Platform: The C621 chipset underpins the Xeon Scalable ecosystem, providing PCIe lane allocation for GPU accelerator cards, NVMe drives, and high-bandwidth NICs. If the deployment includes multiple GPU cards for parallel video analytics inference, the C621's PCIe topology is what makes that expansion possible.
• 2U Rack Form Factor (10.24" H × 43.82" W × 23.43" D): The 2U profile fits standard 19-inch EIA racks and keeps GPU-dense compute from consuming excessive rack units. At 23.43 inches deep, verify your rack's usable depth — shallow-depth racks (under 28") may require a cable-management adjustment at the rear.

Integration and Compatibility

The ESC4000-G4S runs on the Intel® Xeon® Scalable (Skylake-SP / Cascade Lake-SP) platform via the LGA 3647 socket. OS compatibility and PCIe device support depend on the specific CPU SKUs installed — confirm processor TDP against the server's power subsystem before configuring. The ESC4000-G4S (often searched as ESC4000 G4S) is suited for integration with GPU accelerator cards, NVMe expansion, and high-channel network-attached storage architectures. For video surveillance deployments, verify VMS vendor support matrices for the specific operating system and GPU pairing you intend to use — most enterprise VMS platforms (Milestone, Genetec, Avigilon Control Center) publish validated server hardware lists separately from the server hardware itself.

The dual-port Intel® I350-AM2 NIC is broadly supported across Linux and Windows Server distributions, making OS-level NIC teaming or dedicated management/data VLAN separation straightforward without third-party drivers on most modern kernels.

Frequently Asked Questions

Q: What processor socket does the ASUS ESC4000-G4S use?

A: The ESC4000-G4S uses the LGA 3647 (Socket P) socket and supports up to two Intel® Xeon® Scalable processors on the Intel® C621 chipset platform.

Q: How much RAM can the ESC4000-G4S support?

A: It supports up to 2 TB of DDR4-SDRAM across 16 DIMM slots. Individual DIMM modules can be 4 GB, 8 GB, 16 GB, 32 GB, or 64 GB, with a maximum RDIMM capacity of 64 GB per slot.

Q: Are the storage bays hot-swappable?

A: Yes. All 8 bays are hot-swap 2.5" bays, allowing failed drives to be replaced without powering down the server or interrupting recording workloads.

Q: What is the form factor and weight of the ESC4000-G4S?

A: It is a 2U rack-mount server measuring 23.43 × 43.82 × 10.24 inches (L × W × H) and weighing 90.87 lb. Rack weight distribution planning is recommended before installation.

Q: Does the ESC4000-G4S include out-of-band management?

A: Yes. The Aspeed AST2500 onboard controller with 64 MB of dedicated memory provides IPMI-based out-of-band management for remote console access in headless server environments.

A: The server includes an Intel® I350-AM2 dual-port controller supporting 10/100/1000 Mbit/s (Fast Ethernet and Gigabit Ethernet) on both ports, suitable for separating management and data network traffic.

Jerry Tildsen

The ESC4000-G4S is one of those platforms I consistently recommend when an integrator needs to consolidate a high-channel VMS recording environment and GPU-based analytics into a single 2U chassis — the 16 DIMM slots scaling to 2 TB of DDR4 is what sets it apart from lighter single-socket alternatives that cap out far earlier under concurrent analytics loads.

Technical Highlights:

• Dual LGA 3647 Sockets: Two Socket P seats mean you can configure symmetrical NUMA domains across the Intel® C621 chipset — relevant when pinning GPU inference threads to the NUMA node local to the accelerator card's PCIe root complex. Single-socket builds lose that isolation.
• 16-Slot DDR4 Memory Architecture: At full 2 TB configuration using 64 GB RDIMMs across all 16 slots, this platform handles in-memory VMS index caching and multi-GPU frame buffers without thrashing to disk — a meaningful difference versus 512 GB-capped alternatives at sustained throughput.
• 8 Hot-Swap 2.5" Bays: All eight bays are hot-swappable, which is non-negotiable for 24/7 surveillance recording. A drive failure at 3 AM does not require a maintenance window — swap the disk, rebuild the RAID, continue recording. That operational continuity is the spec that matters to operations teams, not just IT.

Deployment Considerations:

• At 90.87 lb, the ESC4000-G4S approaches the single-person lift limit for rack work. Plan for a two-person installation and verify your rack's static load rating before sliding this into a mid-tower IDF rack — many lighter-duty racks are rated under 1,000 lb total and a fully populated GPU server changes the math quickly.
• The 23.43-inch depth is the measurement to check against your rack's usable interior depth after accounting for cable management arms and rear PDU clearance — shallow-depth racks under 28 inches of usable depth will be tight.

This platform is the right call for a centralized analytics node in a multi-site enterprise deployment where a single server needs to handle deep-learning inference across dozens of camera feeds while maintaining a full recording footprint — it is not the right sizing for a branch office with under 32 channels.
