Oracle Launches Low-Cost Storage Initiative


Oracle Corp. is using the same "tie together cheap boxes" mindset that it cooked up for its Database 10g push, but this time, its applying the idea to cheap storage arrays.

The company earlier this week announced the Resilient Low-Cost Storage Initiative, in which its 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, Oracles 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.

"Were showing how you can use Serial ATA storage, which people running data warehouses pooh-pooh, saying that the reliability is too low," Mendelsohn said. "Now we say you can run a lot—[although] maybe not the high-end mission-critical [stuff]."

Oracle has done "a lot of work" to make sure customers can run grids on these low-cost boxes, which include EMC and Dells AX100 and HPs MSA 1500, entry-level SANs (storage area networks) that came out this spring and summer, respectively.

While these boxes are "not as capable" as highly scalable servers, given that they typically can hold only 14 or 15 drives, Oracles 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, Oracles 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."

According to Oracle, a low-cost storage array must implement these core features: networked storage, Inter-Operability Certification, remote management and failure alerts, and high availability.

Thats a list that came at least in part from Oracles 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 didnt have some of these capabilities" such as remote management and failure notification.

"Our IT department didnt like them," Loaiza said. "They said, The box fails, and we dont know whats going on. They insisted, If youre 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 Oracles 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 doesnt 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. ASMs data-mirroring in particular will ensure high availability, Loaiza said.

"Were providing availability from a higher perspective," he said. "We will mirror the data across boxes: Well 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 doesnt matter. We mirror across the boxes."
