Prerequisites for Adding Data Collectors (Dell EMC Unity)
Identify a server where the Data Collector software will be installed. Server requirements include:
64-bit OS. See the APTARE Certified Configurations Guide for additional information.
Support Java Runtime Environment (JRE) 1.8.
For performance reasons, APTARE recommends that you do not install Data Collectors on the same server as the Portal. However, if you must have both on the same server, verify that the Portal and Data Collector software do not reside in the same directory.
Install only one Data Collector on a server (or OS instance).
Data collector must be installed on a system accessible to DELL EMC Unity storage array.
Data collector supports DELL EMC Unity REST API version 4.3.0 for collecting capacity information from DELL EMC Unity storage array.
Read-only credentials (username and password) are required to connect to DELL EMC Unity storage array using REST API.
