This is a great achievement where we have seen the service grow successfully year on year.
The service is powered by an enterprise class infrastructure based across 2 datacentres. The infrastructure consists of 3 major components:
1. Server
2. Storage
3. Network
The server infrastructure consists of three two-node clusters running VMware ESX 3.5. There are two clusters at Bracknell and one at Egham. All hardware is HP Proliant DL. The VMware software components include VMotion, Distributed Resource Scheduling and High Availability features. These products allow us to provide a redundant server environment for the application. Virtual Machines can be migrated between servers to ensure optimal use of resources and prevent downtime in the event of failure.
The storage component is based on Fibre Channel (FC) Storage Area Networks (SANs) at each location that connect the servers to EMC CLARiiON disk arrays. Each server has multiple connections into the SAN and therefore multiple paths to the CLARiiON storage. The disk sub-system at each site uses tiered storage with FC disks allocated to VM Operating System disks and SATA disks allocated to VM data disks. The data disks are configured as Raw Device Mappings (RDMs).
The service is used by over 70 Local Authorities and education service providers, as well as many integrators and Managed Service Providers who rebrand the service as their own.
