Overview
The CSE-126ES2-R2K08P is the 1U chassis of the Supermicro SSG-121E-NES24R all-flash storage SuperServer. It puts 24 × E1.S hot-swap NVMe slots in a single rack unit, accepting both 9.5 mm and 15 mm E1.S modules.
Two full-height PCIe 5.0 x16 slots plus two PCIe 5.0 x16 AIOM slots give the node headroom for 400 GbE networking, and the 2000 W 1U redundant supply supports a fully populated dual-socket board with 32 DIMMs.
Key Benefits
24 × E1.S NVMe in 1U for maximum flash density per rack unit; two PCIe 5.0 x16 AIOM slots for high-speed fabric; 2000 W 1U redundant power; 32-DIMM dual-socket board support.
Applications
Built for all-flash storage nodes, NVMe-over-Fabrics targets, CDN and object-storage gateways, and dense database hosts where I/O density per rack unit is the deciding metric.
