Summary of Capital/Recurrent Expenditure
Brief summary: Enhance the existing suite of access management services offered by OUCS with the implementation of the Core User Directory; sufficient identity and user privilege management to support authentication and authorisation at an appropriate level of granularity within the federated environment; and undertaking a requirements study for the provision of an Active Directory service, with possible rollout from 10/11.
Brief summary: To ensure the HFS can increase capacity to meet projected demands from desktop, server, and groupware requirements, it is necessary to install either an additional server and upgrade to existing server or install a higher specification server to perform both roles. The existing P520 server is expected to host backups from the Groupware service. A feasibility study is also required to assess demand to extend backup services to undergraduates.
Brief summary: The existing Automatic Tape Library is obsolete (13 years old) and needs replacing if maintenance is to be assured and future projected capacity met. The replacement of the tape library should be considered together with the possibility of providing a second, online tape library and backup/archive servers within the new data centre in order to mitigate the risks associated with having a single HFS installation in the OUCS data centre. The provision of a second tape library would negate the need to retain a third tape copy at a remote (and not always accessible) location. Since the replacement of the existing tape library and any second site installation is a significant project, it is proposed to undertake a requirements and feasibility study in 09/10.
Brief summary: Funding has been agreed for the construction of the new Central Machine room but not essential hardware. Current plans suggest a 620kva UPS is required, plus racking, networking, and fire suppressants on day one (all currently out of budget).
Brief summary: Deployment of infrastructure necessary to support dual site locations for business-critical services (racks, server builds to support virtualisation). This item relates to the need to provide virtual infrastructure within the new data centre on which to run business-critical services.
Brief summary: Provision of unified storage infrastructure on which services for the management and curation of research data may be built. It is essential that the infrastructure integrates with a) local filestore provision; b) the OUCS HFS service; c) the OULS repository services. Specific requirements will be known via a proposed feasibility study and one or more externally-funded pilot projects undertaken in 09/10. Infrastructure will be rolled out in phases over three years together with cost-recovery business plan.
Brief summary: To secure and expand the storage and servers for the existing podcasting service, by making use of robust delivery systems with reduced risk of failure. This is required architecture to allow us to keep up with growing demand for storage and delivery.
Below we present (Table 1) an outline over the next five years of potential capital expenditure and recurrent expenditure that OUCS envisages it will need to meet to match escalating demands for its services.
In the first part we summarise the above capital expenditure projects, or one-off funding (e.g. for feasibility studies). It should be noted that some items listed for the future will depend on the outcome of the feasibility studies. In the second part we note the impact these, and other services/expenditure may have on the recurrent costs of running OUCS. Neither of these can be met within OUCS’s existing budget, or indeed if OUCS’s budget for 2009-10 was simply set at breaking even.
In the final part we note the SFWG recommendations. If the baseline is increased by the recommended amount under the SFWG (230k for capital costs and 210k for development) then some items covered in parts I and II would be covered by this. To indicate this those in bold would be covered by the recurrent 230k for capital expenditure, and those in italics by the 210k development fund. No doubt, between now and 2009 other projects will arise.
