High Availability Hosting Platform & Network

Swift utilise the highest quality IBM & Sun (Oracle) Servers to ensure exceptional reliability, however if the worst happens and hardware fails, our High Availability Fail-over system will ensure that downtime is kept to an absolute minimum.

The servers are monitored 24/7 and engineers automatically paged within 15 minutes of a fault being detected so that our services such as our CMS hosting for Magento, WordPress and other CMS does not get interrupted.
If your server fails due to a hardware failure, we can simply mount your container on the SAN from the spare hardware, and boot the container up. This failover process only takes a few minutes with automated scripts, and the data is completely up to date. In comparison, restoring from a back-up takes many hours, and all data since the last back-up is lost.

UK Network UK Network. The networks high availability UK backbone comprises of a heavily redundant 10 Gigabit network across nine major London data centres with automated failover to alternate paths in the event of a network segment failure. See seperate diagram.
Data Centre Local Data Centre Network. Servers are connected to the backbone via two local data networks with automated failover in the event of a firewall, switch, or cable failure; to ensure high availability at the local network level.
Servers Servers. Each hardware node (physical server) hosts a number of virtual servers. Each virtual server is connected to the Storage Area Network (SAN) and does not use local hard drives.
In the event of a physical server failure, the server may be mounted to the SAN from an alternate hardware node and started normally. The advantage is that the downtime is minimised to minutes, there is no loss of data and data is completely up to date.
The diagram illustrates the failure of servers 6-10 on hardware node 2, which are simply mounted and started on hardware node 4.
Storage Storage Area Network (SAN). The storage area network is the key to our hosting platforms high availability. It has been designed with no single point of failure, and can withstand multiple simultaneous failures.
Two dedicated networks are employed for the Storage Area Network, which automatically fail-over in the event of a network failure. Each server is connected to both SAN networks. The SAN Storage server is fitted with two disk controllers which automatically fail-over in the event of a disk controller failure, with each network connected to both controllers. This eliminates any single point of failure, and can even withstand the failure of a network AND controller simultaneously with no loss in service or performance. The disk array employs RAID, and can withstand multiple simultaneous disk failures.
Backup Back-up Storage Server. Each virtual server is backed-up every night to a storage server. The backup may be used to restore a whole server to a hardware node, or individual files. At least 10 days worth of backups are achived.

Network Reliability

Gigabit Ethernet is utilised for Servers, Switches and Firewall’s in the data centre, with multiple redundant connections to a UK-wide 10 Gbit MPLS “Self -Healing” network, so data is automatically redirected in the event of a network segment failure, providing reliability.

The infrastructure comprises of a heavily redundant 10 Gigabit network into key London data exchanges including LONAP, LINX, LIPEX, with further connectivity into Amsterdam (AMSIX & NL-ix), Paris (SFINX) and Frankfurt (DE-CIX). A vast network of over 900 peering sessions are established throughout Europe, enabling direct connection to a quarter of the Internet without passing across a transit connection.

Data Centre

In the event of an area-wide power cut, the UPS systems will provide power while dual 900kVA diesel generators with automatic 25 second fail-over start. Two generators ensure that power is still provided even if one generator fails.

Data centre temperature is controlled by multiple air conditioning systems.

Physical security is provided by 24/7 guard patrols, CCTV and multi-point controlled access to the building and data rooms.

The Data Centre is not located in an area prone to flooding.

Adequate fire prevention measures are in place.
