just want to know, is there any connection between the Operation Manager and the protection manager & Provisioning manager. is there any option as if i can access both protection manager and provisioning manager from Operation Manager.
DataFabric Manager (DFM) is the server component. This component is the heart of the system and runs on a dedicated (no other applications installed) server. Operatoins Manager is the web-based UI that is used to configure/manage/monitor/etc. objects in the DFM database, and is the overall name for the software. Note that there is also a commmand-line interface that is accessible directly on the DFM server itself. Operations Manager also has the components Performance Advisor (included with the package), Protection Manager (licensed component) and Provisioning Manager (licensed component). Your sale/account team should provide more help with identifying your needs and which options match your needs/requirements.
In short: DFM is the heart of the software (server component). Operations Manager is the web-based UI for management/configuration/monitoring. The NetApp Management Console (NMC) provides access to Performance Advisor, Protection Manager, and Provisioning Manager components.
This sizing guide is a guide for **minimal** requirements for basic monitoring. If you plan on adding mulitple objects and enabling Performance Advisor, the server will need to be scaled appropriately to handle the load. Note also the order of performance for host OS: Linux --> Windows --> Solaris, as well the limitations on number of nodes for Solaris. It is always best to engage your sales/account team with your current and future scaling needs to verify sizing. The sales/account team can engage additional resources internally if needed to doublecheck sizing.
