Getting Started with Azure Premium Storage and DataStax Enterprise (DSE)

Microsoft's new Premium Storage offering combines network attached persistent SSD with locally attached SSD cache, making it an interesting storage option for DSE and Cassandra deployments in Azure that need to rely on persistent rather than ephemeral storage. The starter config includes a single P30 disk and a P10 for commitlog IO performance and capacity requirements. Premium Storage extends the cache capability with an additional layer backed by SSD, which can be incredibly powerful when combined with technologies like DTCS. It's important to make some config changes to ensure optimal operation of Azure Premium Storage.
