Infrastructure

It is necessary to determine the performance characteristics of the python member node stack so that deployment guidelines can be developed.

Aspects that need to be determined:

• total number of objects that can be managed
• maximum viable size of objects that can be managed
• number of simultaneous clients that can be supported for common DataONE operations

These are all inter-related and highly dependent on hardware and connectivity, though a baseline set of capabilities should be determined for a commonly available virtual machine configuration so that hardware and connectivity guidelines can be developed for different types of data repositories.
