ASRock Rack 4U8G-ICX2/2T Barebone System — Dual-Processor 4U Rack Server with Intel C621A

The ASRock Rack 4U8G-ICX2/2T Barebone System is a high-density, four-rack-unit server chassis designed for enterprise workloads that demand reliability, scalability, and flexible storage. Built to support two processors on the LGA-4189 socket and powered by the Intel C621A chipset, this barebone system delivers a robust foundation for virtualization, databases, and data-intensive applications in data centers and professional environments. Its scalable architecture, abundant storage capacity, and advanced management capabilities make it a compelling choice for organizations looking to optimize performance per rack unit.

Whether you are deploying a private cloud, hosting large databases, or running virtualized workloads, the 4U8G-ICX2/2T is engineered to meet rigorous enterprise requirements. The chassis accommodates a substantial number of hot-swappable drives, enabling high-capacity storage configurations with flexible RAID options. The combination of dual processors and expansive memory support provides the headroom needed for multi-threaded workloads, while the integrated management features simplify remote monitoring, maintenance, and uptime—key factors in a data-driven environment.

Designed for reliability and long-term readiness, this barebone system benefits from a proven platform that supports modern DDR4 memory speeds and ample DIMM slots, ensuring that you can scale your RAM to match workloads as your business grows. The ASRock Rack lineage is known for building rugged, enterprise-grade hardware, and the 4U8G-ICX2/2T continues that tradition with a focus on performance, expandability, and ease of integration into existing data center ecosystems.

Storage and expansion are at the forefront with 12 x 3.5" drive bays providing significant raw capacity and flexibility for RAID configurations, backups, media storage, or high-performance data access. The combination of SATA RAID support and an NVMe controller enables fast data transfer and efficient I/O scheduling, helping to maximize throughput for demanding applications. Administrators can tailor storage topology to their needs, balancing capacity, redundancy, and performance to meet service-level objectives.

In addition to storage prowess, the system brings compelling management capabilities to the table. The integrated ASPEED AST2500 graphics controller offers 4 GB of graphics memory to support remote management interfaces, KVM over IP, console redirection, and other essential admin tasks—ensuring administrators can manage hardware without physical access to the server. This capability is especially valuable for remote sites, data centers, and environments requiring reliable, out-of-band administration.

How to install ASRock Rack 4U8G-ICX2/2T Barebone System

• Prepare the two compatible processors that fit the LGA-4189 sockets and ensure you have the appropriate CPU coolers and thermal solution for your load expectations.
• Install the CPUs into the LGA-4189 sockets following the processor diagram in the chassis manual, apply thermal paste if required, and secure the heatsinks according to OEM guidelines.
• Insert the DDR4 memory modules into the available DIMM slots, balancing channels per processor to maximize memory bandwidth and conforming to memory population guidelines for dual-processor systems.
• Install storage devices into the 12 x 3.5" bays, configuring the drives for your desired RAID level or using the NVMe controller for non-RAID, high-performance storage paths.
• Connect the NVMe drives to the NVMe controller and ensure the backplane or drive cage is seated properly to provide reliable hot-swap operation.
• Attach power supplies and connect power cables, then boot the system to enter the BIOS/UEFI setup. Configure memory timings, processor settings, and any required virtualization features.
• Configure the storage controller and RAID options within the BIOS or through the appropriate management software, then install your operating system or hypervisor on the desired boot drive.
• Configure remote management settings (IPMI/KVM) via the ASPEED AST2500 interface to enable out-of-band access, monitoring, and alerting for proactive maintenance.
• Perform a final hardware check, verify all fans and sensors are reporting correctly, and run a basic stress test to confirm stability under your expected workload.
