Hardware Sizing
« on: January 10, 2015, 09:43:44 PM »
Frequently asked question: What Hardware Specs are required?

Here are some guide lines:

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.

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.

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.
CCIE RS, CCIE SP, Mnet&sys
