Oracle Launches Low-Cost Storage InitiativeBy Lisa Vaas | Print

The company earlier this week announced the Resilient Low-Cost Storage Initiative, in which it's teaming up with storage vendors Apple Computer Inc., Dell Inc., EMC Corp., Engenio Information Technologies Inc., Hewlett-Packard Co., MPC Computers LLC and Network Appliance Inc.
Andy Mendelsohn, Oracle's senior vice president of Database Server Technologies, told eWEEK.com that Oracle is determined to use the initiative to show customers how they can use storage boxes that are entering the market at the low end and which have been greeted initially with a hairy eyeball.
While these boxes are "not as capable" as highly scalable servers, given that they typically can hold only 14 or 15 drives, Oracle's ability to network them and spread the load across a database storage grid paints an entirely different picture in terms of scalability and reliability, according to Juan Loaiza, Oracle's vice president of systems technologies.
"Traditionally, people have used fairly high-cost storage for databases in general," said Loaiza, in Redwood Shores, Calif. "Similar to the way things have been done on the server side, where they use high-cost servers.
"We introduced RAC [Real Application Clusters] on the server side to tie together low-cost servers. This is the same idea on the storage side: Buy several low-cost storage servers and we spread our data across those to ensure high availability and performance."

That's a list that came at least in part from Oracle's internal IT department, whose members got annoyed when they began tinkering with low-cost storage boxes that were a bit too low-cost, Loaiza said. "Originally, we started looking at really cheap boxes made by no-name vendors," he said. "They didn't have some of these capabilities" such as remote management and failure notification.
"Our IT department didn't like them," Loaiza said. "They said, 'The box fails, and we don't know what's going on.' They insisted, 'If you're going to do this, it has to be remote management and notification.'"
Oracle is now internally storing the Collaboration Suite database it uses in development on three Apple Xserve Raid boxes, each holding 3.5 terabytes.
Oracle is running the setup on a RAC cluster, and each node runs Oracle's ASM (Automatic Storage Management).
On the host side, Oracle uses four Dell Linux boxes, and on the storage side resides the array of the three Apple boxes. The setup is housing Oracle e-mail, voice mail, faxes and files.
The Xserve boxes were a pleasant surprise, Loaiza said. While Apple doesn't have a big name in the storage industry, it was early to market for low-cost storage arrays, initially coming out with a cheap box about 1.5 years ago and into its third generation by now.
The companies in the initiative will work together to develop optimized database storage configurations and best practices for the deployment of low-cost storage with Oracle Database 10g. ASM's data-mirroring in particular will ensure high availability, Loaiza said.
"We're providing availability from a higher perspective," he said. "We will mirror the data across boxes: We'll write one copy into one storage array and the mirror copy into another storage array. This is not going to be as reliable as your $2 million array, each of these $10,000 boxes. But the way we will configure it, if any box dies, it doesn't matter. We mirror across the boxes."
