Dimensioning Virtual Machines
Introduction
We recommend the following virtual machine sizes.
Solution
TruView Small System
This deployment has been tested in situations where there is one TruView Central in combination with one TruView Flow (5K, 20K or 50K) and no TruView Packet.
All appliances are installed from an iso-file provided by COMCERT at the day of installation.
| Virtual Machine Settings | TruView Central Small | TruView Flow 5K | TruView Flow 20K | TruView Flow 50K |
|---|---|---|---|---|
| Type | A | B | C | D |
| CPU (#) | 4 | 4 | 4 | 4 |
| Memory (GB) | 16 | 16 | 16 | 16 |
| Network adapter 1 | 1x VMXNET3 | 1x VMXNET3 | 1x VMXNET3 | 1x VMXNET3 |
| Hard disk 1 (see 1) | 128GB | 128GB | 128GB | 128GB |
| Hard disk 2 (see 1) | 32GB | 250GB | 1TB | 2.5TB |
| Hard disk 3 (see 1) | 256GB | No hard disk 3 | No hard disk 3 | No hard disk 3 |
| OS (see 2) | CentOS 7 | CentOS 7 | CentOS 7 | CentOS 7 |
TruView Medium Systems
This deployment has been tested in situations where there is one TruView Central in combination and any combination of TruView Flow appliances to a total of 300K flow/s and up to four TruView Packets.
All appliances are installed from an iso-file provided by COMCERT at the day of installation.
| Virtual Machine | TruView Central Medium (type E) | TruView Flow 5K (type F) | TruView Flow 20K (type G) | TruView Flow 50K (type H) |
|---|---|---|---|---|
| Type | E | B | C | D |
| CPU (#) | 8 | 4 | 4 | 4 |
| Memory (GB) | 32 | 16 | 16 | 16 |
| Network adapter 1 | 1x VMXNET3 | 1x VMXNET3 | 1x VMXNET3 | 1x VMXNET3 |
| Hard disk 1 (see 1) | 128GB | 128GB | 128GB | 128GB |
| Hard disk 2 (see 1) | 100GB | 250GB | 1TB | 2.5TB |
| Hard disk 3 (see 1) | 2TB | No hard disk 3 | No hard disk 3 | No hard disk 3 |
| OS (see 2) | CentOS 7 | CentOS 7 | CentOS 7 | CentOS 7 |
TruView Large Systems
These are the offcial NetScout virtual machine specifications.
| Virtual Machine | TruView Central | TruView Flow 5K | TruView Flow 20K | TruView Flow 50K |
|---|---|---|---|---|

| Network adapter 1 | 1x VMXNET3 | 1x VMXNET3 | 1x VMXNET3 | 1x VMXNET3 |
| Hard disk 1 (see 1) | 275GB | 275GB | 275GB | 275GB |
| Hard disk 2 (see 1) | 100GB | 250GB | 1TB | 2.5TB |
| Hard disk 3 (see 1) | 3TB - 10TB | No hard disk 3 | No hard disk 3 | No hard disk 3 |
| OS (see 2) | CentOS 7 | CentOS 7 | CentOS 7 | CentOS 7 |
(1) It is important to respect the order and sizes of the hard disk. All hard disk must be thic provisioned. Disk 2 and 3 performace must be no less than 300 IOps.
(2) For information only; the OS is part of the *.iso and it will be installed together with the application.
