Oracle Database Appliance

Reprinted: http://www.hellodb.net/2011/09/oracle-database-appliance.html

Since Oracle acquired sun, it not only obtained MySQL, Java, Solaris, but also Sun's hardware products. It has truly become a service provider of hardware and software kill. Over the past few years, we have successively launched the database all-in-one machine exadata X2 and middleware all-in-one machine exalogic Based on Sun hardware products, and even brought the idea of combining software and hardware to the extreme. Among them, the most depressing non-HP does not belong. From the original partners to competitors, exadata uses Sun hardware, Oracle discards the anteng processor, and even the CEO has switched to Oracle.

Recently, Oracle launched a cheap database All-in-One ODA (Oracle Database appliance). This product is also a product of the combination of hardware and software. It aims to provide low-end and low-end users with low costs and simplicity, the high-availability database all-in-one machine is combined with exadata. exadata competes with minicomputers and high-end storage, while ODA occupies the low-end and mid-end markets using PC servers.

Let's take a look at the hardware features of this machine:

Oracle builds a two-node rac system in the 4u space. Two servers with dual x5675cpu + 96 GB memory are built in, and 20 600 gb sas disks and 4 GB SSDs are shared, the built-in 10-ge switch is used for RAC node Interconnection (InfiniBand is used for node interconnection of exadata ). SSD is used to store redo logs to improve performance.

The biggest feature of Oracle is the combination of hardware and software. This system uses Oracle Linux, Oracle Database 11gr2 RAC, and appliance manager dedicated for configuration and management to improve management and ease of use.

Compared with building databases on your own PC using ODA, You can implement a high-availability RAC system without buying SAN storage and 10-ge switches. Another major feature of the software and hardware all-in-one machine is simple configuration and plug-and-play. Oracle helps you with everything. However, this advantage may be a disadvantage for some users, because it is not flexible enough and the Black Box is not transparent enough.

However, for most users, simple, easy to manage, and high availability are the most basic requirements. It seems that ODA meets these requirements. Of course, the price is also an important factor. The target users of ODA should be small and medium users. Users with no money will usually buy minicomputers, high-end storage devices or exadata. If the price is reasonable, I believe there is still a large market.

It is worth noting that ODA encapsulates all the systems in one box, which virtually increases the risk. In exceptional circumstances, the entire system may become unavailable, such as power failure or storage damage. Therefore, considering the availability issue, one set is definitely not enough. At least another set of replica uard should be bought. However, the cost is a little high. Considering that ODA is definitely more expensive than buying a PC server, you can purchase a PC as a dedicated uard to reduce costs and improve availability.
