Ultra-High I/O DeHs

The flavor type for ultra-high I/O DeHs is i3. Ultra-high I/O DeHs use high-performance local NVMe SSDs to provide high storage input/output operations per second (IOPS) and low read/write latency. They are suitable for high-performance relational databases, NoSQL databases (e.g. Cassandra and MongoDB), and ElasticSearch.

Ultra-high I/O ECSs can be deployed on i3 DeHs.
