Ensuring System Requirements are Met

Due to the potential for a very large number of objects being collected, analyzed, and maintained by the application, there are several aspects of the underlying server that must be taken into account. The sizing of the supporting server or virtual machine (VM), depends upon the size and complexity of the underlying environment.

Sufficient processing power and CPU memory must be present to support effective collection and server data handling and analytics. Collected data is staged in memory prior to passing to the collector database.

The following sections describe the requirements for small and large collection environments, as well as for the Agent Manager.

•	Small Environment System Requirements

•	Large Environment System Requirements

•	Requirements for Agent Managers

Small Environment System Requirements

A small collection environment can typically have its storage collection handled by using the StorageCollector agents installed on the embedded Agent Manager that is available on the Foglight Management Server machine. The resource requirements shown below are the minimum needed for collection in a small environment.

 

NOTE: If scalability is important, use an external Agent Manager instead of the embedded Agent Manager. Follow the system requirements described in Large Environment System Requirements instead of these requirements.

Table 4. System Requirements

CPU	8-way 2.4 GHz CPUs — one of the following: • 2 quad core • 4 dual core • 8 single core
RAM	20 GB in total: • 10 GB for the Management Server • 6 GB for the Management Server Database Repository • 2 GB for the operating system • 2 GB for Agent Managers and agents and repository
Storage	Storage: • 20 GB for the Management Server • 100 GB for the Management Server Database Repository If using an embedded database repository: • Total of 140 GB on a RAID device available on the Management Server machine If using an external Database Repository: • 40 GB on a RAID device available on the Management Server machine • 100 GB on a RAID device for the external Database Repository

Databases must be regularly backed up and maintained to reduce wasted space.

Large Environment System Requirements

A large collection environment requires that the Agent Manager for the Storage Collector agents be installed on a server that is separate from the server running the Management Server. Requirements for both machines are outlined below. Refer to the System Requirements and Platform Support Guide for virtual machine and Agent Manager collection requirements.

 

Table 5. Management Server, Browser Interface, and Database Repository on a 64-bit Foglight-supported Platform

CPU	4-way 2.4 GHz CPUs — one of the following: • 1 quad core • 2 dual core • 4 single core
RAM	28 GB in total: • 16 GB for the Management Server • 8 GB for the Database Repository • 4 GB for the operating system
Storage	If using a built-in embedded Database Repository: • 220 GB, on a RAID device If using an external Database Repository: • For Management Server: 60 GB, on a RAID device • For Database Repository: 160 GB, on a RAID device

 

 

Table 6. Agent Manager on a 64-bit Windows or Linux Platform

CPU	4-way 2.4 GHz CPUs — one of the following: • 1 quad core • 2 dual core • 4 single core
RAM	6 GB in total: • 5 GB for Agent Manager and agents • 1 GB for operating system
Storage	30 GB on a RAID device

Databases must be regularly backed up and maintained to reduce wasted space.

Requirements for Agent Managers

Whether you use the embedded Agent Manager or external Agent Managers, you need to make sure that the hosting server meets the supported platform requirements. Agent Managers that are used for Foglight for Storage Management collections must be installed on a server running a supported 64-bit Linux operating system or a supported 64-bit Microsoft Windows operating system.

Foglight for Storage Management has been tested on the following environments.
