Avaya Aura® Device Services requires 250 GB of disk space. Avaya Common Server Release 3 (CSR3) and below servers might not have the required amount of disk space. If you are planning to deploy Avaya Aura® Device Services on CSR3 or below servers, ensure that these servers have enough disk space by installing additional physical disks to your servers. Alternatively, you can use the updated Avaya Solutions Platform (ASP) 130 Release 5.x server, which has the required amount of disk space by default.
