1.2. Hardware Requirements¶
A typical Acronis Software-Defined Infrastructure 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.
| Type | Management node | Each storage and compute node |
|---|---|---|
| CPU | 64-bit x86 processors with AMD-V or Intel VT hardware virtualization extensions enabled. 16 logical CPUs* |
64-bit x86 processors with AMD-V or Intel VT hardware virtualization extensions enabled. 8 logical CPUs* |
| RAM | 32 GB** | 8 GB** |
| Storage | 1 disk: system + metadata, 100+ GB SATA HDD 1 disk: storage, SATA HDD, size as required |
1 disk: system, 100+ GB SATA HDD 1 disk: metadata, 100+ GB SATA HDD (only on the first three nodes in the cluster) 1 disk: storage, SATA HDD, size as required |
| Network | 1 GbE for storage traffic 1 GbE (VLAN tagged) for other traffic |
1 GbE for storage traffic 1 GbE (VLAN tagged) for other traffic |
* 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.
