Servers located in CLEAR LINK's fortified data center facility provide primary and secondary domain name service (dns) and primary and backup mail exchange service are all immediately redundant by functioning to operate in the event either system would fail. CLEAR LINK's data center & public server standards are configured in two ways: Production/Redundant - Fully redundant power supplies, RAID arrays (minimum of RAID-1 for operating system and minimum of RAID-5 for data/storage) and hot-swap fan trays. This configuration is used for production (or live) data which is stored only on this server. Production/Replicated - Single power supply, no raid array (OS and data can be stored on the same physical drive, but operating system and data MUST be logically sepearated) and non hot-swap fan trays. This configuration is used for production (or live) data which is fully replicated to one (or more) servers - thus creating redundancy through clustering. A minimum of one system of each standard, along with spare parts are also stored in CLEAR LINK's storage locker for any equipment that may fail while the redundant system carries the load. In additional to server systems, CLEAR LINK provides a wide range of security solutions. Redundant and fail-over Cisco, Watchguard and Zyxel firewall systems provide port blocking, intrusion detection, AV, AM, total UTM and URL filtration and are installed and functioning to operate in the event of a system failure. |
