Block Storage

Storage for Large Data Processing and DB Workload

Block Storage stores data in fixed-size blocks of pre-determined arrays and assigns directly to servers. This highly available storage service is suitable for application environments that require high capacity data, such as database and email servers. High performance storage is available depending on the required level of performance. Backup policy with redundancy and failure recovery system enable reliable service without any data losses.
