Hard drive capacity and the number of OTP hosts to be managed are the primary considerations for your OTP system.
Hard drive capacity is affected by three factors: the number of OS distributions that are to be provisioned, the management log files generated by Open Telecommunications Platform components, and the size of the applications to be provisioned. OS distributions are stored in the /var/otp file hierarchy on the first OTP host. Allocate 3 Gbytes for each OS distribution and each distribution's associated profiles and scripts.
System processing is affected by three major factors: The number of additional OTP hosts being managed, the types of monitoring being performed on the additional OTP hosts, and the number of jobs running on the first OTP host.
