Hardware Requirements

Your clustered deployment must have a minimum of three nodes with each node having the following specifications. We recommend having five nodes for high availability.

Hardware	Specifications
CPU cores	Minimum: 8 physical cores or 16 vCPUs Recommended: 16 physical cores or 32 vCPUs
CPU architecture	x86 (64-bit)
Network speed	10 Gb/s or higher
Memory	64 GB, 128 GB recommended
Storage	Enough disk space in /var/lib/gravity to support 24 hours of data retention. 1 TB of storage recommended. This is where Gravity stores containers and state information. You can change where Gravity stores this information at install-time. See the Extract and run the Data Stream Processor installer section on the Install the Data Stream Processor topic for more information.

To reduce the latency of communication between DSP components, all nodes in the DSP cluster should be interconnected via a low-latency network. For example, in cloud deployments, components must be placed in the same region and availability zone. DSP does not support multiple availability zones.
