Frequently Asked Questions about 19-Inch Rack Mountable Computers:

The maximum capacity of ECC (Error Correcting Code) RAM varies depending on the server model, motherboard chipset and CPU generation (e.g. Intel Xeon Scalable, AMD EPYC). Rack servers typically support from 128 GB up to several terabytes of DDR4 or DDR5 ECC RDIMM/LRDIMM. Numerous DIMM slots allow granular memory expansion - this is essential for stability and data integrity, especially in virtualised environments (e.g. with VMware vSphere, Microsoft Hyper-V, KVM, Proxmox VE) or for database-intensive applications.

Rack servers offer a wide range of storage solutions for maximum performance and data security:

  • Multiple hot-swappable bays (2.5" or 3.5") for SATA, SAS (12G/24G) or NVMe U.2/U.3 SSDs and Enterprise HDDs.
  • Dedicated hardware RAID controllers (e.g. Broadcom MegaRAID, Microchip Adaptec) for optimised I/O performance and data security through RAID levels such as 0, 1, 5, 6, 10, 50, 60.
  • Onboard M.2 slots for fast NVMe SSDs, ideal as boot drives for the hypervisor or as a cache tier.
  • High-density systems with up to 24 or more drive bays per height unit (HU) for storage-intensive applications.

Rack servers typically include multiple onboard network interfaces — usually 1 Gbps or 10 Gbps Ethernet. Some models also offer 25 Gbps, 40 Gbps, or even 100 Gbps connectivity for high-throughput environments. Additional network cards can be added via PCIe slots to meet more demanding requirements.

1U servers are particularly compact and allow a high packing density, but are often louder and offer less space for components and cooling. 2U and 4U servers offer more space for larger fans, additional drives and expansion cards, but are therefore less space-saving. The choice depends on the area of application and the individual requirements. We will be happy to advise you on buying the right rack server.

Rack servers offer hot-swappable drive bays for SATA, SAS and NVMe SSDs/HDDs. Typical RAID levels are 0, 1, 5, 6 and 10, realised via hardware RAID controllers such as Broadcom or H730. For maximum performance and redundancy, you can use NVMe SSDs and RAID 10.

Configure Your Rack Server

Our configuration options allow you to customize not only the primary components of your Rack server but also advanced elements such as the number and type of PCIe slots (for GPUs, FPGAs, or specialized I/O cards) and even specific firmware versions.

  1. CPU selection:Start by selecting the processors — whether you need a single or dual-socket setup with the latest Intel Xeon Scalable processors or AMD EPYC CPUs. These are optimized for core count, clock speed, cache size, and TDP to suit your workload.
  2. Add RAM:Enhance your system with ECC RDIMM or LRDIMM DDR4/DDR5 memory to support even the most memory-intensive applications, such as in-memory databases or advanced virtualization with multiple hypervisors.
  3. Choose storage:The next step is to select the appropriate storage media. Consider whether you need extremely fast Enterprise NVMe SSDs for latency-critical applications or whether you prefer the proven reliability of server SAS SSDs for business-critical workloads. A dedicated RAID controller ensures the necessary data security, whilst a host bus adapter enables efficient communication with external storage enclosures.
  4. Select motherboard and chassis:The Server Motherboard is the backbone of your server and must support all selected components. Ensure compatibility with your chosen CPU and sufficient slots for RAM, storage, and add-on cards. The chassis must be rack-mountable, offer sufficient cooling, and allow for future expansion.
  5. Network connectivity:Networking is just as flexible. In addition to onboard LAN ports, you can integrate additional network adapters with bandwidths ranging from 10GbE to 200GbE via PCIe slots. This ensures optimal connectivity to your central Ethernet switch, core switches or Storage Area Networks (SANs).

Each Rack server includes a built-in Baseboard Management Controller (BMC) with IPMI 2.0 and Redfish® API support for full out-of-band management — including remote KVM, virtual media mounting, and sensor monitoring. Also consider redundant, hot-swappable power supplies with high efficiency ratings (e.g., 80 PLUS Platinum or Titanium) to ensure maximum uptime and energy savings.

The Advantages of Rack Servers

Rack servers are known for their compact design and the performance required to handle a wide range of workloads. They also offer numerous additional benefits:

  • Easy scalability: With rackmount servers, IT infrastructures can be expanded quickly and easily. From small businesses to large data centers, their modular design makes them highly adaptable to changing requirements.
  • Centralized management: Thanks to their structured rack-mounted arrangement, all components are easily accessible for maintenance. Rackmount servers also support remote management features, allowing efficient control of systems even across multiple locations.
  • High performance: Rack servers are built for continuous operation and deliver maximum performance. They support powerful multi-core processors and large amounts of memory, making them the ideal basis for high-speed storage servers and data-intensive applications.
  • Energy efficiency: The airflow and cooling design of rack servers is highly optimized, reducing heat buildup and energy consumption. This not only lowers operating costs but also extends the lifespan of hardware components.
