IT Services provides dependable and resilient virtual servers for Schools and departments. Using industry-leading virtualisation software from VMware and high quality server and storage components we are able to offer reliable and highly-available virtualised servers that are centrally funded.
Our data centres are mirrored synchronously – in real time – between two physical locations. The ability to move virtualised servers to other physical hosts at either site gives an expected availability in excess of 99.99% and offers a complete failover option to another site in the event of a disaster affecting one of the sites or during planned site downtime.
All storage is deployed over redundant disk arrays in a RAID configuration which offersexcellent protection against disk failures. We use a number of separate backup technologies to ensure we can recover virtual servers in the event of a disaster, and implement Microsoft shadow copies on departmental virtual servers to allow server managers to recover individual files and folders.
By default department virtual servers will be administered and kept secure by a department server manager and IT Services responsibility is simply to keep this facility available. IT Services also offer a managed service for those wishing to delegate the administration and security of the server to ITS.
Applications running within the virtual server operating system are the responsibility of the supplier / support contract and remote access, via the VPN service, can be given on request.
IT Services can provide servers running Microsoft Windows and CentOS Linux distribution.
Microsoft SQL Server can be provided, but before requesting a virtual server you should contact firstname.lastname@example.org to discuss licensing costs.
It is not possible to support hardware dongles or similar physical devices as this will prevent the virtual server from migrating between Data Centres during monthly maintenance or in a disaster scenario.
IT Services recommend a default configuration of processor cores; storage and memory for virtual servers that allows us to make optimal use of our resources and minimising our environmental impact. The default configuration for a virtual server is 1 processor core (2 when running Microsoft SQL Server), 2GB of memory and 100GB storage. For Windows this split over 3 drives C: System (40GB), F: Application install (50GB) and L: Logs (10GB) For Linux / System and home directories (40GB) /DATA Application install (60GB). This is monitored at the virtualisation layer and can be increased in response to demand or to meet supplier support contract requirements.
