ARB Hardware Requirements

The rapid growth of the rRNA data sets has caused severe limitations for many users related to the ARB hardware requirements. ARB is a so-called "in-memory" database and the larger the databases are, the more main memory (RAM) is required by ARB to handle them. Basically, there are two options to face the problem: (1) hardware upgrades or (2) reduced data sets.

The SILVA project has now addressed the second option by providing a non-redundant (NR) SSU Ref data set which contains a significantly reduced number of sequences but still is representative. For more information check the SILVA SSU Ref NR project section.

In addition, the following table, provided by Ribocon, will help you to find out more about the ARB hardware requirements: ARB/SILVA Memory Requirements v1.3 (pdf, 34 kb)
