Hi, Thanks for your question. This thread may help. [URL] It shouldn’t affect performance, but it may limit the max file size it to 2GB per file.   Let us know if you have any additional questions.
We have recently migrated data to the Isilon. in some instances, we have had the requirement to ensure that a 32bit client can use the NFS export . The customer would like to apply the 32bit setting to all the NFS exports regardless of whether the client is 32bit or a 64bit client . Is there a potential performance impact for the 64bit clients if the setting is applied to all NFS exports?
