Striking a solid storage strategy

Striking a solid storage strategy

With the data flood continuing to rise, organisations must strike a sensible storage management strategy to help them forge ahead.

CommVault managing director, Gerry Sillars, said the company was growing at 36.7 per cent globally and hiring in Australia in the middle of a global financial crisis.

“Some 78 per cent of our new business comes up against Symantec,” he said. “And some 70 per cent of our displacement customers are ex-Symantec.”


Many of those organisations choosing to backup to disk rather than tape are also looking to take advantage of deduplication.

The basic premise of which is that at some stage in the backup process, an algorithm is run over all the files to identify duplicate copies of the same file. One copy is preserved, the others deleted – a pointer to the single instance that has been preserved is left in their place.

“De-duplication is becoming commonplace – it’s now not a question of whether to do it but why you wouldn’t do it,” Fujitsu solutions architect, Aaron Bell, said. “It simply allows you to store more information on disk, making more information accessible and retrievable.”

Sillars agreed and expected deduplication to win more users over to disk.

“We have been convinced for several years that people would want to do backup to disk for rapid restore,” he said. “With de-duplication, you can significantly reduce the amount of disk needed for each backup.”

That said, CommVault is also “actively looking” at ways to take deduplication technology to tape.

Another technology changing the face of storage management is virtualisation. While it has existed within storage arrays for many years, the popularity of server virtualisation has naturally engulfed the storage world with its charms.

Virtualised storage abstracts the usable disk space available within storage systems from the physical device itself. Its main benefit to customers is to increase the utilisation of storage assets they already own.

“The key tangible outcome is the re-use of existing infrastructure – using older hardware as a lower tier of storage,” Hitachi Data Systems chief technology officer, Simon Elisha, said. “Customers love the thought of not throwing stuff out.”
