Dual 14-core Xeon Gold 6154 compute

This 1U rack server ships with two Intel Xeon Gold 6154 processors, each running at 3.00GHz with 14 cores. The 256GB of DDR4 ECC memory operates at 2666MHz and supports up to 3TB total capacity. It targets organisations running virtualisation clusters, database workloads, or mixed application hosting in a compact form factor.

Eight-bay 2.5-inch SATA storage limit

The chassis provides eight 2.5-inch drive bays populated with four 1.92TB SATA SSDs and a BOSS-S1 controller managing two 240GB M.2 SATA drives for boot. The included HBA330 controller presents these drives without hardware RAID acceleration. All storage uses the SATA interface, so throughput is bounded by that standard rather than faster protocols.

Replaces older single-socket or HDD-based 1U servers

Organisations moving from single-processor platforms or mechanical-drive arrays gain a second CPU, ECC DDR4 memory, and all-flash SATA capacity in the same rack height. The jump is worth it when workloads need more simultaneous threads, larger memory footprints, or predictable SSD latency without changing rack infrastructure.

Questions about this item

Which storage configuration should I choose between the 1.92TB SSDs and the 240GB BOSS drives?

The four 1.92TB SATA SSDs provide the main capacity for virtual machines, databases and backups, while the two 240GB SATA M.2 drives on the BOSS-S1 card are intended for the operating system or boot partitions.

What does the 3.00 GHz clock speed mean for actual workload performance?

Each Gold 6154 processor runs at 3.00 GHz with 18 cores, delivering high per-core frequency for responsive virtualization, database and application hosting.

How does the HBA330 controller affect the SATA drives in practice?

The HBA330 presents the four 1.92TB SATA SSDs and two 240GB BOSS M.2 drives to the operating system without hardware RAID, so software or OS-level mirroring is required for redundancy.
