50 OMNM 6.5.3 Installation Guide
• Neither Firewalls nor other restrictions block communication for ICMP, SNMP, FTP, TFTP,
SCP, SSH, Telnet, HTTP
• SMTP and internet access are required for notification from OMNM by e-mail as well as for
license/subscription renewal
• The following system requirements:
Requirement Description
Virtual Machine VM is configured with 1 processor and 4 cores. 6-8 cores are recommended for
Production/Non-trial environments with 500-1000 devices.
Adjusted the number of cores needed based on the application performance by
right-clicking the imported VM and selecting a settings option for adjusting a VM’s
resources.
CPU Speed exceeds 3.0 Ghz.
Memory Minimum 12 GB RAM allocated to the VM.
Disk Space Minimum 120 GB allocated to the VM.
The OMNM VM is pre-set to installation defaults and dynamically grows up to
85 GB. If the VM is used beyond a trial evaluation, you may need more space
depending on your specific usage and needs. For example, higher data retention
policies for performance, TFA, audit logs, and events increase the database space
needs. Allocate more space by increasing the:
• Space allocated to the VM from the hypervisor (Hypervisor > select the VM >
settings)
• OMNM mysql database size
Refer to the OpenManage Network Manager User Guide for detailed steps on how
to extend the Mysql database size. Consult your VM and/or Linux administrator
before adjusting the VM size.
The database should consist of 1 or more 10-15K RPM disk, or the equivalent solid
state disk for better performance.
Make sure that the VMware virtual disk runs on adequately performing physical disk
infrastructure. Heavy performance monitoring and TFA requires disk IO speeds that
support this configuration.
If you plan to use the VM beyond the initial trial configuration, consider some
configuration changes to ensure proper system sizing. Refer to the OpenManage
Network Manager User Guide for sizing recommendations before converting the trial
VM to a production usage. You may need to:
• Expand the storage capacity to accommodate the workload data and retention
preferences.
• Allocate additional memory to support a production environment
Virtual Appliance

• VMware Workstation v8 or higher
• vSphere® Hypervisor (ESXi) 4.1 and higher (must meet virtual appliance, port
access, and listening port requirements)
Ports Use All necessary ports and firewall settings are pre-configured on this VM. Refer to the
OpenManage Network Manager User Guide for ports details.
