Microblade Server

The COTT Bare-bones Microblade Server is an entry-level 1U Micro-Cloud Server that allows the system to support up to 3 hot-pluggable server nodes in a 1U chassis height and 6 hot-pluggable server nodes in a 2U, with each server node individually operating according to your needs and allowing for the flexible configuration of each server node.

Versatile and Flexible Configurations

Maximum of 6 nodes in the system to fulfill requirements and application needs. Each node supports 4x DIMM slot, with a capacity of up to 64GB ECC DDR4. Standard node supports up to 2×3.5″ or 4×2.5″ internal drives. For a total of 6×3.5″ or 12×2.5″ internal drives are supported in a fully-configured system. Supports one HHHL PCLe 3.0×8 card via dedicated COTT riser card. Each node supports 1x dual 10GbE RJ45(INTEL 82599)mezzanine module option.

High Availability and Capability

The system design is based on Intel® E3 V5/V6 Greenlow platform and the Intel® PCH C232 chipset. The system support the Intel® Xeon® Processor E3-1200 V5/V6 (LGA1151) platform,maximum TDP is up to 80W.

Centralized Power Supply, Strong Stability

The system is equipped with 1+1 hot-swappable 500W 80+Gold redundant PSU. It uses a centralized power supply and 1+1. redundant power supply to ensure system stability.

Rear Smart Fan Control
