Hardware Sizing
« on: November 19, 2014, 12:52:57 PM »
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.
