Oracle Exadata X9M Generation Cloud @ Customer • The registry
Oracle has released the latest upgrade to its Exadata database appliance series, claiming to improve earlier iterations on I / O and throughput.
Building on the legacy of tightly integrated hardware and software it acquired with Sun Microsystems in 2009, Big Red’s enhanced Exadata X9M claims Online Transaction Processing (OLTP) with over 70% of Higher input / output operations per second (IOPS) on its previous version, the X8M. Oracle also estimates that the system operates with 19 µs I / O latency from database to storage, 10 times faster than flash memory.
Exadata X9M is touted as enabling customers to reduce the costs of running transactional workloads by up to 42% and analytical workloads by up to 47%, compared to the previous generation, Oracle said. Meanwhile, analytical workloads ran 87% faster.
Oracle uses Remote Direct Memory Access (RDMA) instead of I / O to read persistent memory file stores between the database server and the storage server to reduce latency, Ashish said Ray, vice president of product management at Oracle Exadata.
“It’s an architectural change in the sense [of] how we integrated the persistent memory directly into the Exadata storage servers: it is the software, which integrates completely with the application. So when we bring this layer into our storage server, it means that all database workloads can immediately take advantage of the system as it is now in this shared storage server. IOPS increases dramatically and latency decreases. “
Big Red is also taking Exadata to the cloud – sort of. It is available under the name Cloud @ Customer X9M, which means that it is located in a customer or hosted data center, but is managed by Oracle, on a cloud internal to the customer. In this configuration, Oracle claims 50 times higher OLTP I / O latency than on-premises AWS RDS and 100 times higher than Azure SQL.
Competition aside, performance would appeal to both Oracle customers looking to upgrade and users with high performance workload requirements, said Noel Yuhanna, senior analyst at Forrester.
“Many large companies that are not Oracle customers could also benefit from Exadata because it can deliver higher performance and throughput,” he said. “What people really need today is a fully automated system that can scale very well. [so] they can provide high-performance, low-latency access to critical data without having as many resources to optimize it. “
Outside of the use cases that require the highest performance, users may find better options. “I would say if you are looking for a low end database or a lower performing database, there are obviously better choices, like open source databases,” he said.
Carl Olofson, vice president of research at IDC, said he had no reason to doubt Oracle’s performance because the Exadata technology “is solid.”
However, as with any built-in proprietary system, there are downsides, he said. “Your flexibility to migrate later is limited. That’s the trade-off: reduced future flexibility in exchange for speed of execution and simplicity of database operations, management and development. “
Oracle’s primary goal is to provide users with a migration path that requires no effort, delivers benefits, and utilizes the applications and expertise of Oracle staff. “New customers would be more welcome,” said Olofson.
He agreed that users looking to move databases between platforms might find Oracle’s approach difficult. While it is possible to run Oracle databases on AWS, for example, “Oracle has a particular way of charging for AWS compute that has put a lot of people off,” he said.
“For high-end workloads, Oracle Database users should look to Exadata and Oracle Autonomous Database. For midsize workloads, there is real cost competition here with a range of cheaper alternatives. But the devil is in the details. The user should consider current and future needs and consider all cost factors.
“Plus there’s a tendency to give in to emotion and say ‘more Oracle no matter what’ because of past sales tactics. I think everyone has to get past that.” ®
