Hardware requirements

A minimum Virtuozzo Hybrid Infrastructure installation recommended for production consists of three nodes for storage and compute services with enabled high availability for the management node. This is to ensure that the cluster can survive failure of one node without data loss. The following table lists the minimal hardware requirements for all the three nodes. The recommended configurations are provided in "System requirements" in the Administrator Guide.

Type Management node with storage and compute

64-bit x86 processors with AMD-V or Intel VT hardware virtualization extensions enabled.

16 cores*


1 disk: system + metadata, 100+ GB SATA HDD

1 disk: storage, SATA HDD, size as required


10 GbE for storage traffic

1 GbE for other traffic

* A CPU core here is a physical core in a multicore processor (hyperthreading is not taken into account).
