Maximum number of enclosures example: <strong>MSA</strong> <strong>2040</strong> drive enclosures<br />
The following figure shows an example of an array configuration that demonstrates the maximum<br />
number of enclosures (eight, including the controller enclosure) that are allowed in an array<br />
configuration.<br />
An <strong>MSA</strong> <strong>2040</strong> array is connected to seven <strong>MSA</strong> <strong>2040</strong> drive enclosures. Each <strong>MSA</strong> <strong>2040</strong> drive<br />
enclosure contains 12 drives, and the <strong>MSA</strong> <strong>2040</strong> LFF controller enclosure contains 12 drives.<br />
Combined, the total number of drives adds up to 96 LFF drives, but no additional enclosures can<br />
be connected, because the maximum of 8 enclosures has already been reached.<br />
NOTE: When connecting more than two drive enclosures, you may be required to purchase<br />
additional 1m or 2m cables. Spanning 6 or 7 enclosures requires a 2m mini-SAS cable to enable<br />
the proper bend radius.<br />
