The work units that contribute to this business line are Mainframe Systems, Midrange Systems, Architecture and Security, Application Services and Business Services. Service delivery is provided from offices and facilities in Darwin. Ensure governments critical business systems operate in a computing environment that is flexible, reliable and secure, with high levels of performance and availability Previous Years Current Year Target Key Deliverables Performance 2012-13 Actual 2013-14 Actual 2014-15 Actual 2015-16 Actual 2016-17 Estimate 2016-17 Actual 2017-18 Budget Monthly cost per million instructions per second (MIPS) n/a n/a $1 090 $1 114 $1 045 $1 019 $1 050 Mainframe computing availability n/a n/a 100% 100% 100% 100% 100% Virtual server computing availability n/a n/a 100% 100% 100% 100% 100% Physical servers hosted in data centre n/a n/a 551 415 415 405 415 Fully managed servers 700 889 1 000 1 195 1 350 1 330 1 450 Data storage area network (terabytes) 1 300 1 512 2 100 2 615 3 200 3 200 3 700 MOVEMENTS BETWEEN ESTIMATE AND ACTUAL 2016-17 Monthly cost per million instructions per second (MIPS) reduction achieved due to new mainframe enterprise licensing agreement and higher than anticipated client demand. Physical servers hosted reduction reflects continuing trend by clients to convert from physical servers to virtual servers. MOVEMENTS BETWEEN 2016-17 ACTUAL AND 2017-18 BUDGET Monthly cost per million instructions per second (MIPS) cost per MIPS is expected to normalise as client demand returns to usual levels, along with the reduced processing for some batch workloads. Fully managed servers reflects the increase expected for CCSRP in 2017-18 and agencies moving from agency owned to fully managed servers. Data storage area network (terabytes) anticipated continued growth and CCSRP establishing a footprint. Physical servers hosted 2016-17 target results indicate that the 2017-18 estimate needs to be revised down. TREND ANALYSIS COMMENTS Monthly cost per million instructions per second (MIPS) cost decrease in 2016-17 results from increased demand and lowering of some software costs, with costs expected to normalise in future years. Physical servers hosted downwards trend reflects the transition from physical to virtual server technology. Fully managed servers increase year on year results from agencies moving to utilise computing resources as a service from Data Centre Services. The cost efficiency of virtual server computing has incentivised this trend. The effect of major projects like CCSRP is expected to increase volumes in future years. Data storage area network (terabytes) growth results from a steady transition of agencies digital data into the centralised storage network and continued growth in the volume of data in agency ICT systems. The effect of major projects like CCSRP is expected to increase volumes.
