Earthquake Resistance Structures
The Premysis Data Center is built on an earthquake resistant plate designed to absorb the shaking of an 8.0 magnitude earthquake.
The Premysis Systems Data Center has 8 OC48’s blended 20Gbit/s, and load balanced from multiple carriers using diverse entry into the building to multiple AT&T CO’s. The Data Center has a route science load balancer that will intelligently find the quickest and best quality route, even if it’s a longer route with more hops. The Data Center has a 24/7 NOC, redundant CRAC cooling systems, humidity control, 24 hour battery backup with a generator that stores up to two weeks of diesel fuel.
Technical Highlights-Customer Side:
Premysis ensures that the customer’s LAN and WAN are optimized by ensuring that the voice traffic, (which is “real-time” traffic) has the highest priority from the phone to the switch. This is done with 802.1q VLAN tagging.
When traffic is passed from the switch to the router, the traffic carries the same VLAN on the LAN side of the router. The router is set up with QoS and will ensure that UDP traffic (voice-traffic) has a higher priority as it leaves the Internet connection. We prefer a non shared WAN service such as DSL, T-1 or MPLS as these circuits have a direct connection to the closest central office.
The central office has a high capacity fiber optic connection to the core internet backbone. Backbone interconnections are always multiple OC192 10Gbit/s or OC768 40Gbit/s and are always upgraded as usage hits 80% of capacity.
Technical Highlights-System Architecture:
When voice traffic comes in, it is routed by two redundant 6509 Cisco routers. The System is made up of a cluster of redundant Sun Servers that run Mitel call control software configured as user and trunking gateway systems.
Dial tone is provided by multiple PRI’s coming from multiple fiber connections, backed up by SIP trunking that can be routed over one of the 8 OC48 connections. All telephony applications run on a high available VMware environment tied into a 16TB SAN.
