Unity 6900 hardware overview
The Unity 6900 deployment includes two Unity 6900 controllers with automatic failover and Active/Active
Clustering in a 2U form factor. They have dual E5-2640v4 CPUs and 192GB RAM + 16GB NVDIMM per
controller. The Unity 6900 includes a quad-port for connectivity to Unity Storage Expansions. Each controller
includes a chassis inter-connect used for multipathing, providing high speed, low-latency communication
between the two Unity 6900 controllers.
Unity 6900 is an high-level system comprised of dual-controllers and internal storage. In addition to the front
bay storage, you can connect up to eight Unity Storage Expansions. The capacity-optimized configuration is
best suited for:
backup
unstructured files
specific applications that benefit from advanced caching
Drive configurations in the front bay can be 6 / 12 / 18 / 24.
