Umbrellar's datacentres are designed to a redundant architecture. Mains powers an online UPS systems which has more than 30 minutes of battery life.
All servers, switches and routers are supported by this unit. This ensures that the load is completely isolated from the mains source and is not dependent upon mains power in order to provide uninterrupted power to the datacentre. Diesel generators provide backup units that start automatically should the power fail, and provides power to the UPS, air conditioning systems and internal office systems ensuring continuation of service in the event of an extended power failure.
Umbrellar can also provide geographically diverse disaster recovery and remote site fail-over options to alternate datacentre facilities where required.
Umbrellars datacentres are independently alarmed and monitored via both radio frequency communication and by telephone line as a back up to the Armourguard control centre. A failure of the radio frequency 'poll' is considered to be an alarm. Management is notified immediately of all alarm conditions.
Servers and SAN
All servers are IBM enterprise class systems, including state-of-the-art blade systems, with RAID disk technology to ensure that processors keep running in the event of a disk failure. Umbrellar has a high availability IBM & HP SAN solutions to support its VPS clusters and Shared Virtual Hosting environment. Servers are housed in lockable 19" rack mount enclosures. The server room itself is a "room within a room" with no external walls. Entry is via a security locked door accessible only via Umbrellar's customer support department by authorized personnel.
