Frequently asked question: What Hardware Specs are required?

The Performance Guide is a good hardware sizing guide.

Here are some guide lines:

Disk

* If peak performance is important use SSD drives.
* When using mechanical disks, higher RPM drivers and larger disk caches perform better. Also consider RAID.
* When going the RAID route, avoid raid controllers that require a proprietary driver and semi-software raid.
CPU

* In a MultiSite environment, multi-core CPU's perform better. 4+ CPU threads recommended.
* In a high speed point to point scenario, a CPU with higher single-thread ratings will perform better. 4 CPU threads recommended.
RAM

* Appliances in 'High' require about 1 GB for each peer.
* Appliances in 'Low' require 1 GB for each 'high' peer and 0 GB for other 'Low' peers.
Case Study 1:
Head Office with 12x 2 Mbps remote branches in a hub and spoke scenario. Recommended hardware for the remote sites is the Wanos 200 or equivalent. For the Head Office Xeon E3-1230, 16 GB RAM, 256 GB SSD.

Case Study 2:
A network with 6 fully meshes 10 Mbps sites all configured in 'High'. Recommended hardware for each site Xeon E3-1230, 8 GB RAM, 256 GB SSD. For example : HP DL320e G8.
