Hardware recommendations

• Virtuozzo Hybrid Infrastructure works on the same hardware that is recommended for Red Hat Enterprise Linux 7, including AMD EPYC processors: servers, components.
• Even though a cluster can be created on top of varied hardware, by using nodes with similar hardware in each node will yield better cluster performance, capacity, and overall balance.
• It is not recommended for production to run Virtuozzo Hybrid Infrastructure on top of SAN/NAS hardware that has its own redundancy mechanisms. Doing so may negatively affect performance and data availability.
• It is recommended to use UEFI instead of BIOS if this supported by your hardware. This is recommended particularly if you use NVMe drives.
• Any cluster infrastructure must be tested extensively before it is deployed to production. Such common points of failure as SSD drives and network adapter bonds must always be thoroughly verified.
