SAN FRANCISCO: Oracle has fleshed out further details of its Exadata X3 update, which shifts data read and writes away from disk drives and onto flash and RAM.
The Exadata X3 Database In-Memory Machine is based on a mass memory hierarchy, which Oracle said automatically moves all active data into flash and RAM, while keeping less active data on low-cost disks.
Compared to the current Exadata offering, the X3 offers four times the flash memory capacity, with up to 40 percent faster response times and 100GB/s data scan rates, according to Oracle, supporting up to 1.5 million writes per second.
Juan Loaiza, senior vice president, Oracle Systems Technology, said that with this iteration of Exadata, the focus has shifted from on-disk data with memory for speeding it up, to a focus on in-memory data with disk to support that.
“We also have faster processors and more networking, but the big headline is that we have so much memory, our compression will suit all workloads,” he added.
While Exadata X2, launched at OpenWorld in 2010, had 5TB of flash, this has now been increased four times to 22TB, along with 2TB or 4TB of DRAM in one rack.
“The hardware price is exactly the same as the X2, even though we added all this extra stuff, and it’s available now,” Loaiza said.
For current Exadata customers, there is the option to either migrate the data from older machines to the new X3, or they can create a single database across multiple Oracle hardware, including the V2 machine launched in 2009 and the Exadata X2.
“We also have a new release of the software that adds capabilities, this also runs on the old hardware. With the software update, firms can automatically cache data in flash, using it as a destination for database writes,” Loaiza said.
Loaiza declined to give specific numbers on Exadata customer numbers, instead referring to “thousands of Exadata deployments”.
