The reduction in the average price per annum to manage server is primarily due to the increase in servers without employing any additional staff. The flexible, reliable and secure environment builds confidence with our customers increasing demand on the service. The improved economies of scale are contributing towards cost effective service delivery. 2. The cost of storage dropped by approximately 20% due to the purchasing of an upgrade to the SAN infrastructure. The upgrade was to meet client demand for storage, which is improving our economies of scale. 3. The increase is due to agencies deploying more applications on midrange servers and having Midrange Services manage them. Performance Highlights A new type of server architecture was implemented during the year, which allowed the building of several, so called virtual servers on a single piece of server hardware. This has introduced savings in server management overheads and hosting costs. Data Centre Services will be pursuing this architecture further in the future, reducing the number of physical servers installed. There has been an increase in the number of servers hosted in the Data Centre from 136 in June 2003 to 172 in June 2004. The provision of a secure environment with fail-safe systems and 24 x 7 monitoring is recognised as a valued service by our customers for their key business systems. Security of the facility was further enhanced after isolation caging was installed in the Data Centre to provide enhanced physical security for high security servers.
