The result? Cummins says it has in many cases cut its backup windows in half.
"In the larger Oracle servers, the time it took for a full backup went from 12 to 14 hours to five to six hours," Bitts says.
What has helped shorten backup times is that the ADIC Scalar 10K has more tape drives than do the StorageTek libraries Cummins was using before, so the tape library can devote more resources to a single backup job. Another advantage is that servers connected to the Brocade SAN fabric are able to back themselves up directly. Previously, all of the backup traffic had to go over the Gigabit Ethernet network to the Veritas media server, and then to the DLT drives.
Besides performance improvements, an important factor that weighed in the decision, Price says, was ADIC's pay-as-you-grow option for the Scalar 10K: The unit has about 3,000 cartridge slots, but Cummins opted to buy a license for 1,800. "As we need additional tape slot capacity, we can pay the next increment," Price says.
And he definitely expects to need that additional space: "We used to see 50 percent growth rate over time in our storage. Now we're seeing 100 percent annual growth rate."
