SYS-221BT-DNTR

Multi-node specification scope

Processor, memory, slot and drive limits apply per node unless explicitly labeled shared-system. Do not merge per-node and shared-system resources.

Supply scope — exact configuration agreed separately

Configurable server platform, not a fixed installed CPU/RAM/storage build. Per-node and shared resources remain separate on multi-node systems.

System node topology

Two hot-pluggable systems (nodes) in a 2U form factor. Each node supports the following:

Chassis height

3.47" (88 mm)

Chassis width

17.68" (449 mm)

Chassis depth

28.75" (730 mm)

Platform form factor

2U Rackmount

Documented selection limits

Configurable server platform: CPU, RAM, drives, GPUs, networking adapters and optional licenses are not asserted to be installed. All capacities are supported limits or configuration options, not delivered capacity. Agree the exact BOM separately. Multi-node counts and limits retain per-node versus shared-system scope. NVMe/SAS/SATA, risers, cooling and power redundancy may require specific optional hardware and workload validation. No stock or lifecycle guarantee.
