Sorry for the inconvenience but there are limitations to the 2.4 Kernel on the NAS 2.0. On NAS-XSR it's not just the Software RAID features but greater expansion on Logical Volumes up to 16TB plus much more as identified on the following link.
The Open-E NAS-XSR family is the new generation of the Open-E NAS software. Compared to the Open-E NAS, the NAS-XSR family offers up to 60% better performance, Logical Volumes up to 16 TB, improved hardware compatibility and more features, like software RAID, cross data synchronization and Anti-Virus.
The Open-E NAS-XSR has now new Tuning Tools and support for Infiniband to increase the high data-throughput of the NAS servers based on the Open-E software.
