世界上最大规模的内存数据库SAP HANA产生
日前，Oracle总裁埃里森(Ellison)，惹出不实言论，他在Oracle Open World上声称：" SAP HANA"规模太小，不及Exadata X3。声称HANA只有不到最大0.5TB的内存，而Exadata X3可以达到26TB。
这个不实言论，马上被SAP反驳，事实上，SAP HANA已经上线的系统，最大内存已经达到100TB，甚至可以扩至250TB。
真是冤家路窄。大规模内存数据库实时计算领域，完全看好HANA。

Larry Ellison’s remark, “SAP HANA is really small,” during the Oracle OpenWorld keynote this week has provided SAP an opportunity to lay the facts squarely on the table. |
It could go down in IT history as the week Larry Ellison officially declared war on SAP HANA by making false claims about its own in-memory database product Exadata X3 and SAP’s platform for real-time business. Ellison, CEO of Oracle, is known for his brash public statements denigrating new trends that don’t fit into his world view, such as the Cloud and in-memory computing. After the remark, SAP wasted no time responding to Ellison’s statements in order to “set the record straight.”
Ellison’s assertions were made during his opening keynote speech at Oracle OpenWorld, the company’s annual customer event, held in San Francisco this week. Ellison claimed that the company’s Exadata X3 has 26 terabytes (TB) of memory, while purporting that SAP HANA is a “small machine” providing only 0.5 TB of memory.
“Clear distortions misrepresenting SAP HANA”
SAP experts countered, saying that both claims were false. On Tuesday, Vishal Sikka, member of the SAP Executive Board and head of technology and innovation, posted a blog to the SAP sponsored website experiencesaphana.com expressing his concern about what he called Ellison’s “distortions.”
“Oracle made statements that are clear distortions and misrepresent SAP HANA,” wrote Vishal. “We do not serve our stakeholders well by misstatements and omissions of key things we know to be true.” Vishal then went on to compare the major differences between the two products, even inviting Ellison to Santa Clara, California, to visit the largest HANA system built so far. He was referring to an installation partnered with IBM. Steve Mills, senior vice president and group executive at IBM Software & Systems came to the support of SAP with a statement about the joint project: “IBM and SAP have partnered to demonstrate an SAP HANA system at 100 TB, making it the largest in-memory database system in the world. That system, running on 100 IBM nodes, can now scale to 250 TB.”
Steve Lucas, SAP’s general manager for Database & Technology, also refuted the claims made by Oracle’s CEO. Speaking to the web-based journal, Business Insider, Steve said: “Let’s just say it’s taken me 24 hours to get my eyebrows to lower to their normal position.” Steve provided his estimation of
Oracles Exadata X3: “Oracle is obviously following our lead, but their current efforts (X3) fall far short of what we are already delivering. X3 is still a hybrid system and an attempt to confuse and pacify customers.” Steve said that X3 consolidates databases onto one appliance and allows for some of the data to be stored in DRAM. “With a US$ 10 billion database albatross around Oracle’s neck, it’s obviously difficult for them to really to innovate,” he summed up Oracle’s current predicament.
