max file size in isi nfs export view

Hello,

When i check the tech spec guide from EMC support site, the max file size is shown as 4T

However, when i check the default setting for the max file size, it shows around  Max File Size: 8192.00000P , does that mean the max file size is set to 8192 Peta Byte whereas the actual size on the isilon cluster supported is 4TB ?  can someone provide insight on this ?
