Virtual machine from OVF properties

Introduction

InfiniStream virtual appliances are build from OVF.

These are the properties of the vitual machines immediately after deployment.

Solution

nGenius Flow Collector Virtual Appliance

Virtual Hardware	Size
CPU	8
Memory	8 GB
Hard Disk 1	50 GB (Thick Provisioned)
Hard Disk 2	(*)
Network adapter 1	E1000

(*) The size of this hard disk depends on the number of flows per second received form all flow exporting devices and the number of days you want detailed session data to remain available.

Use this table for guidance:

Flow per second (f/s)	Retention	Hard Disk 2 Size
5k	7 d	200 GB
20k	7 d	800 GB
50k	7 d	2 TB
5k	14 d	400 GB
20k	14 d	1600 GB
50k	14 d	4 TB

The second hard disk shall be Thick Provisioned.

 

vSTREAM (standalone)

This is vSTREAM, a virtual machine dedicated for network monitoring.  Read this article on resources used by vSTREAM Agent.

Virtual Hardware	Size
CPU	2 (#)
Memory	4 GB (#)
Hard Disk 1	32 GB (Thick Provisioned)
Hard Disk 2	($)
Network adapter 1	VMXNET3

(#) We deploy vSTREAM with two interfaces for monitoring.

($) The size of the second hard disk that will serve as data store, is configurable during ovf deployment.

The size of this hard disk depends on the expected traffic volume and how long you want packets to be available; it should not be less than 100GB.
