Splunk Enterprise on Azure - D(S)4_v2 - size of data storage, disk types, configuration ?

[MkyGiblin]

Using the Splunk Enterprise provisioning template in Azure through Microsoft Marketplace...

When selecting Server type D(S)4_v2, as suggested, how much data storage is provisioned for the 'single instance' implementation of Splunk ?

What are the disk types and how are they configured?

[jconger]

When Splunk is provisioned in Azure via the marketplace, 1 OS disk is provisioned to run Splunk and 8 data disks (each one is 1023 Gib) are provisioned to store data. These data disks are striped into 1 volume.
