The advantages of Rack servers in 19-inch format

Rack servers in 19-inch format offer numerous advantages for an efficient IT infrastructure:

  • Space saving: With the option of vertical mounting in 19 inch racks, rack servers can be stacked efficiently, allowing many devices to fit into a small space - ideal for data centres and companies with limited space.
  • Easy management and maintenance: Rack servers have a modular design and are easy to install, maintain and upgrade. IT teams can quickly access individual servers to perform updates or repairs.
  • Scalability: Rack servers can be added or removed as required, allowing flexible customisation of the server infrastructure.
  • Improved cooling and noise reduction: Optimised ventilation ducts maximise airflow in the rack, keeping servers cool and preventing overheating. Modern ventilation systems also reduce noise pollution in the data center.
  • Increased security: Rack servers can be installed in lockable racks, which restricts access to authorised personnel and protects sensitive data.

Frequently Asked Questions About Rack Servers:

What is a rack server?

A rack server is a compact server that is mounted in a standardised 19-inch rack. It saves space, is easily expandable and is particularly suitable for companies that require high performance, scalability and centralised management.

Which form factor is best for my rack server use case?

The optimal form factor depends on your performance, expandability, and space requirements. A 1U server is suitable for basic applications, while 2U or 4U servers offer more room for storage, network cards, or GPUs. For data-intensive or graphics-heavy workloads, larger servers may be necessary. We’re happy to provide tailored advice to help you find the ideal solution.

What expansion slots are available on rack servers?

Rack servers typically offer multiple PCIe slots that can be used for expansions such as network interfaces, RAID controllers, or graphics accelerators. The exact number depends on the form factor and model. Modern servers often also support NVMe expansion via U.2 or M.2 connections.

How easy is it to expand storage on a rack server?

Many rack servers support hot-swappable drives, allowing you to replace or add drives while the system is running. Thanks to modular chassis designs, adding extra HDDs or SSDs is usually straightforward. Whether you're using SATA, SAS, or NVMe – with the right backplane design, upgrades are typically tool-free and quick. Storage pools and RAID controllers can also be flexibly configured.

Do rack servers come with built-in redundant network connections?

Yes, many systems are equipped with multiple network interface cards (NICs), often with redundancy. If one connection fails, another can automatically take over. This not only enhances fault tolerance but is also essential for features like load balancing and failover strategies.

What RAID options are supported by rack servers?

Depending on the configuration, rack servers support RAID 0, 1, 5, 6, 10, and often more advanced setups like RAID 50 or 60. These RAID levels protect against data loss due to drive failure and can boost performance. We offer systems with integrated hardware RAID controllers or software RAID, depending on whether you prefer hardware acceleration or greater flexibility.

Do rack servers support hot-swap functionality?

Hot-swappable drives and power supplies are standard features in professional rack servers. This means you can replace components during operation without shutting down the server. This ensures continuous uptime – a key advantage for critical applications where every minute of downtime is costly.

What cooling measures are required for rack servers, especially in data centers?

Rack servers feature advanced airflow management with multiple redundant fans. In data centers, additional measures such as cold aisle/hot aisle separation and, if necessary, rack or in-rack cooling systems help maintain optimal operating temperatures.
