Some of the best things come in small and unobtrusive packages. At Oracle OpenWorld last week, Oracle silently announced the next generation of the Oracle Database Appliance (ODA) with the X7-2S, X7-2M and X7-2 HA models.
S&M, no L!
If you actively follow the ODAs, the first change that is immediately noticeable is the lack of a “L” (or Large) model, and the rationale is simple… users no longer need it!
The last two releases of the ODA had some limitations, and the X7s address these directly and efficiently. First, let’s look at the previous X6 S/M/L models, all powerful systems but lacking in storage capacity. The largest of the systems (X6-2L) could only be upgraded to 28.8TB of NVME storage, and the S and M models were limited to 12.8 TB of raw NVME space. For many databases, this became an issue, due to the growth of the data being stored in databases. This growth has accelerated with new development methods, like a RESTFul interface to data, that make it easier for developers to harness to power of the Oracle database technology.
NVM Express (NVME), also know as Non-Volatile Memory (NVM), is architected from the ground up for flash storage technology. NVME significantly improves both random and sequential performance by reducing latency, enables high levels of parallelism, streamlines the command set while providing support for security, and provides end-to-end data protection. For the Database, this means that NVME based storage provides up to 3x performance improvement over legacy flash SSD, and allows even a “small” ODA to do more I/O Operations per second than most enterprise SAN arrays can support.
The new “small” models, allow for up to 51.2TB of NVME space, and include two 10GBaseT ports, and two integrated 25 Gbe network ports that can down sync to 10G using SFP+ connectors. While the new X7-2S stays at 10 cores, the base memory increases to 192GB of RAM. The X7-2M bumps the core count up to 36 and the base memory to 384GB of memory, and is expandable to 768GB of ram. This additional memory is important, because these models can now be virtualized, allowing application servers to coexist with the database.
What’s the BIG news? The HA model underwent a large makeover as well.
The HA model’s biggest change is that like the Exadata, it is now available in two base models, a “HP” model, that focuses on High Performance SSD storage, and a High Capacity “HC” model that uses tradition 10TB HDDs. This enables raw storage maximums up to 128TB of SSD, or 300TB of HHD storage.
The HA model also can now run the SE edition of Oracle database when virtualized. Powering the virtualized system is 72 cores, and a based memory configuration of 768 GB which is expandable up to 1.5TB of ram. This new ODA resolves the I/O limitations of the X5 generation, and the capacity limitations of the X6 generation, making it the most powerful ODA released to date.
If you have an older X5, and need to improve I/O performance, a migration of the X7 should be considered.
There are many new software features with the next generation of ODA, including support for Database 12.2, new deployment options for storage, a new web interface to manage the appliances and more.
