This article gives a more detailed view on the Exasol Cluster Architecture. A high level view is provided here.

Exasol Cluster Nodes: Hardware

An Exasol Cluster is built with commodity Intel servers without any particular expensive components. SAS hard drives and Ethernet Cards are sufficient. Especially there is no need for an additional storage layer like a SAN.

See here for a list of Exasol Certified Servers.

The building blocks of an Exasol cluster are commodity Intel servers like e.g. Dell PowerEdge R740 with 96 GB RAM,12 x 1.2 TB SAS Hot-plug hard-drives and 2 x 10Gb Ethernet Cards for the private network. That’s sufficient to deliver outstanding performance combined with high availability. The picture below shows a 4+1 cluster, one of our most popular configurations:

The commands IMPORT and EXPORT provide an easy way to transfer data between Exasol and other data sources like an Oracle database. You may at first get this error message: Oracle instant client not available. Please ask your administrator to install it via EXAoperation.

Here’s how to do that yourself without having to ask your admin

• Exasol
• export
• IMPORT
• TOI

We have had our annual conference Xperience in Berlin again – it was an amazing event with a packed agenda full of customer success stories and technical news. This year at the Umspannwerk.

One nice and easy way to make yourself familiar with Exasol – the leading In-Memory Analytic Database – is the Community Edition. It’s free and can be downloaded here as a virtual machine running on VirtualBox.

A good description how to install the Community Edition can be found here.

There’s an Exasol SQL Client called EXAplus. You can use it as GUI, then it looks like this:

Exasol is the name of a company based in Nuremberg, Germany and the name of its major product: An in-memory analytic database.

That database leads the recent TPC-H benchmarks, delivering outstanding performance while running on commodity hardware.

Technically, Exasol is a clustered RDBMS using a shared nothing architecture. Availability is achieved with spare nodes, like in this diagram:
