System Architecture

Product ArchitectureOpmantek's solutions are 3-tier applications comprised of a (shared) backend database, an application layer, and the presentation layer. While these can be decoupled and hosted on separate platforms, it is generally not necessary. In some rare situations, clients may benefit from hosting the Mongo DB on a separate server from the other applications. Single-ServerOpmantek's solutions are designed to be deployed on a single server, as demonstrated by the Opmantek VM. However, how well this deployment will scale is dependant on several factors, including:
In most situations, the deciding factor limiting server scaling is the ability to read/write data to the storage device. Opmantek strongly recommends fast, local SSD over traditional hard drives. Multiple Server, No High AvailabilityOpmantek's licensing is based on the total number of devices/interfaces being collected and not the number of servers deployed to do the collection. As a result, you can install Opmantek's products on multiple servers in order to spread the load. This results in lower resource requirements for each virtual machine (resulting in a lower probability of resource contention and oversubscription). A common architecture for this is to split products onto separate servers by feature -
Multiple Server, w/High AvailabilityWhile this is the most flexible architectural option it does require a license of Opmantek's opHA module. This option provides the ability to scale collection horizontally across multiple Pollers, and then have those devices report up to one or more Master servers at the top-tier. This architectural option should be considered in the following situations:
Document Architecture DecisionNow that you've selected your system architecture you should spend a moment to document your decision. You should include all relevant factors considered in making your decision, which subnets will be covered by each server, a generalized list of devices by manufacturer and model each server will monitor, and any network or device configurations required (i.e. SNMP/WMI credentials, network security changes, etc). |
Server Sizing
Server sizing is both an art and a science. However, there is a good bit of math to throw in there when determining minimum storage requirements.

Storage RequirementsThe biggest limiting factor in server performance is disk IO. The system must be able to have unrestricted read/write access to the storage medium. Opmantek highly recommends the use of local SSD storage over traditional hard drives. NMIS
