CSC has added one-fifth more floor space and upgraded the power capabilities of its Clayton data centre as part of a multi-million dollar investment in Victoria.
The IT services giant's chief financial officer Wayne Banks said the work also included a front-of-house refurbishment for staff on-site.
"Some of the refurbishment was expanding the raised floor to enable some more capacity," Banks said.
"We also did a little work upgrading our own power capabilities to make sure we had all the redundancy required by a bigger centre."
The Clayton centre housed "critical data for Defence and Federal Government agencies and well as a range of local and global commercial clients", according to the IT services firm.
Banks said the refurbishment of the Clayton facility was part of a wider national project to bring all of CSC's data centres up to tier-4 standard.
Its West Australian centre was yet to be upgraded to tier-4 but still could be "depending on the [ongoing demands] of our client base."
In Victoria, Banks said CSC had clients "with expanding footprints" and the company was also seeing an uptick in clients wanting to use what he called "cloud-style technology".
"It made good business sense to expand the data centre footprint while we could," he said.
CSC said today it would invest $78 million over 10 years through its new offices in Docklands, Melbourne. The offices will house approximately 450 staff.
CSC's Victorian clients included BHP Billiton, ANZ, GE Money, Motorola, Worksafe Victoria, Department of Defence, Powercor-Citipower, Toll Holdings, and David Jones.
