1.2. Hardware Requirements

A typical Virtuozzo Infrastructure Platform installation recommended for production consists of a single management node and at least four nodes for storage and compute. The following table lists the minimal hardware requirements for the management node and storage/compute nodes. The recommended configurations are provided in the Installation Guide.

* A logical CPU is a core (thread) in a multicore (multithreading) processor.

** Each CS, e.g., storage disk, requires 1 GB of RAM (0.5 GB anonymous memory + 0.5 GB page cache). The total page cache limit is 12 GB. In addition, each MDS requires 0.2 GB of RAM + 0.1 GB per 100TB of physical storage space.
