R2 Rack Server
Rack Compute · 2U · Full-Width

The T18 R2.
The balanced middle of the fleet.

A 2U dual-socket platform that pairs full-fat compute with 12 to 24 hot-swap storage bays. The default node type for private cloud, virtualization and hyperconverged fabrics in the GCC.

01 — Overview

The default node for private cloud and virtualization across the GCC.

Storage where you need it

Twelve or twenty-four 3.5"/2.5" hot-swap bays support hybrid SAS/SATA + NVMe topologies. Ideal for hyperconverged fabrics that need CPU and capacity in the same chassis.

PCIe Gen5 throughout

Eight Gen5 slots, dual OCP 3.0 mezzanines, and a signal-integrity path validated for 400GbE + PCIe 5.0 concurrently — not on paper, on the scope.

Dual-path storage backplane

Redundant SAS4 expanders and NVMe switch fabric mean a failed drive path is not a failed node. Standard on every R2.

Rack Manager Integration

Ships with T18 Rack Manager templates for OpenStack, Nutanix AHV, VMware ESXi 8, and OpenShift 4.
