Now the disk-to-disk backup system enables Venetian Macao to shorten its backup window to 3.5 hours and improve the performance of mission-critical applications during data backup time.

"Improved performance and the much shortened backup window are crucial to us," said Gilson. "We can't have planned outages at casinos where no closure window is possible--we can't ask people to come and play from 6am to 4pm."

Tiered storage is also possible with the system. According to Gilson, high-availability transaction systems for its casinos are now on tier-one storage while other business areas occupy tier-two and tier-three storage.

"We expect 30% cost-savings from buying a new storage system compared with upgrading the previous HP storage system," Gilson noted.
