All DSP releases prior to DSP 1.4.0 use Gravity, a Kubernetes orchestrator, which has been announced end-of-life. We have replaced Gravity with an alternative component in DSP 1.4.0. Therefore, we will no longer provide support for versions of DSP prior to DSP 1.4.0 after July 1, 2023. We advise all of our customers to upgrade to DSP 1.4.0 before July 1, 2023 in order to continue to receive full product support from Splunk.

Splunk Enterprise versions
The Data Stream Processor officially supports sending data to Splunk Enterprise 7.1.0+ instances hosted on Linux.
Your clustered deployment must have a minimum of three nodes with each node having the following specifications. We recommend having five nodes for higher availability.
|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 |
|Storage type||The Splunk Data Stream Processor requires low latency storage. You should install the Splunk Data Stream Processor on SSDs.
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.
