Virtual Machines and Servers Orion NPM installations on VMware Virtual Machines and Microsoft Virtual Servers are fully supported if the following minimum configuration requirements are met for each virtual machine. Note: SolarWinds strongly recommends that you maintain your SQL Server database on a separate physical server. Virtual Machine Configuration Orion NPM Requirements by License Level SL100, SL250, or SL500 SL2000 SLX CPU Speed 2.0 GHz 2.4 GHz 3.0 GHz Allocated Hard Drive Space 2GB 5GB 20GB Note: Due to intense I/O requirements, SQL Server should be hosted on a separate physical server configured as RAID 1+0. RAID 5 is not recommended for the SQL Server hard drive. Memory 2GB 3 GB 3 GB Network Interface Each installation of Orion NPM should have its own, dedicated network interface card. Note: Since Orion NPM uses SNMP to monitor your network, if you are unable to dedicate a network interface card to your Orion NPM installation, you may experience gaps in monitoring data due to the low priority generally assigned to SNMP traffic.
