Experts: Avoid big mistakes with Oracle's Exadata

Presenters at the recent Collaborate user conference gave their tips

Although Exadata is Oracle's most popular and mature "engineered system," some customers implementing the database machine are making mistakes that prevent them from getting the most performance out of the expensive product, according to a veteran of many Exadata projects.

Many people have seen Oracle's advertisements that sing Exadata's praises and cite astounding-sounding performance improvements over running the same workload on traditional hardware, said Andy Colvin, practice director with Oracle consulting firm Enkitec, during a presentation at the Collaborate conference in Las Vegas last week.

A lot of databases are hindered because they're running on servers with older hardware and fibre channel interconnects, as well as a shared SAN (storage area network). Exadata targets these problems with features such as dedicated storage and Infiniband interconnects.

"You get away from everybody else," Colvin said. "You get to be the kid with your own sandbox, so you're not sharing storage with the rest of the organization."

Maybe as a result of this, some customers "think of [Exadata] as throwing hardware at a problem, and it's really not," Colvin said. Simply moving workloads over to Exadata will typically result in a three-times performance improvement, he added.

But the "smart scan" technology afforded by Exadata's specialized storage software "is where the magic really happens," Colvin said.

A few key moves are highly important. For one, Exadata can benefit from a smaller SGA (system global area), Oracle's name for the shared RAM space used by a database instance. "If you start small it will recognize you have a small buffer cache," he said. "It's going to utilize all that power you have down at the storage tier."

However, this advice mostly applies to data warehouses deployed on Exadata, according to Colvin. OLTP (online transaction processing) queries typically need larger SGAs, he said.

But in general, new Exadata customers should realize they "aren't special," and avoid making too many arbitrary tweaks, Colvin said. "You've got a nice fancy system Oracle has configured and tested."

Meanwhile, it might even be a big mistake to buy Exadata at all, as it could be overkill, according to another presenter at Collaborate.

Automotive parts manufacturer Gentex is running its substantial ERP (enterprise resource planning) system with a combination of commodity servers and storage, said Cliff Burgess, director of IT at the company.

It went with the combination after getting the hard sell from Oracle on an Exadata upgrade. The solution Gentex ultimately came up with ended up involving far less additional hardware than Oracle's representatives claimed it would, according to Burgess.

Oracle customers who need more performance would be well served to determine whether simply some faster chips, additional RAM and solid-state cards would solve their problems, versus buying an Exadata, he added.

That advice comes as Oracle's sales organization is placing heavy emphasis on Exadata and other engineered systems, versus commodity boxes. Oracle recently passed the 10,000 mark for sales of engineered systems, CEO Larry Ellison said during the company's third-quarter earnings call last month.

For Oracle, engineered systems represent a much more lucrative opportunity than the hardware alone, given they get loaded with plenty of high-margin software licenses that subsequently generate annual maintenance revenue streams.

All things to consider when the Oracle Exadata salesman comes calling, according to Burgess.

"Don't let Oracle come in and sell you the shiny box," he said. "As a customer, I don't want what's best for Oracle, I want what's best for me."

Educating from the epicentre - Why distributors are the pulse checkers of the channel

Educating from the epicentre - Why distributors are the pulse checkers of the channel

​As the channel changes and industry voices deepen, the need for clarity and insight heightens. Market misconceptions talk of an “under pressure” distribution space, with competitors in that fateful “race for relevance” across New Zealand. Amidst the cliched assumptions however, distribution is once again showing its strength, as a force to be listened to, rather than questioned. Traditionally, the role was born out of a need for vendors and resellers to find one another, acting as a bridge between the testing lab and the marketplace. Yet despite new technologies and business approaches shaking the channel to its very core, distributors remain tied to the epicentre - providing the voice of reason amidst a seismic industry shift. In looking across both sides of the vendor and partner fences, the middle concept of the three-tier chain remains centrally placed to understand the metrics of two differing worlds, as the continual pulse checkers of the local channel. This exclusive Reseller News Roundtable, in association with Dicker Data and rhipe, examined the pivotal role of distribution in understanding the health of the channel, educating from the epicentre as the market transforms at a rapid rate.
