Scale SAM for larger environments
|Stackable Pollers Available?||Yes. For SAM 6.2 and higher. Two polling engines can be installed on a single server.|
|Poller Remotability Available?||
Yes, for SAM versions 5.5 and higher
Poller remotability is a feature that enables the local storage, using MSMQ, of up to ~1 GB of polled data per poller in the event that the connection between the polling engine and the database is temporarily lost.
|Primary Poller Limits||
~8-10k component monitors per polling engine.
25-50 concurrent Orion Web Console users.
One APE for every 8-10k component monitors.
Maximum of 150k component monitors per primary SolarWinds SAM installation (i.e. 1 SAM server + 14 APEs).

|WAN and/or Bandwidth Considerations||
Minimal monitoring traffic is sent between the primary SAM server and any APEs that are connected over a WAN. Most traffic related to monitoring is between an APE and the SolarWinds database. Bandwidth requirements depend on the size of the relevant component monitor. Based on 67.5 kB / WMI poll and a 5 minute polling frequency, the estimate is 1.2 Mbps for 700 component monitors.

WMI is best suited for environments where latency is < 100ms.
