NXPowerLite for File Servers compatibility and system requirements

Recommended System Resources

NXPowerLite for File Servers can be run on physical or virtual infrastructure however, we recommend the following or similar configuration for best performance.

Configuration Value
OS Windows Server 2016 or higher
Physical RAM  8GB
CPU 4-core i5 (8 virtual cores) or similar
No. of optimizers 4


Device Compatibility

NXPowerLite needs to be installed on a Windows machine but it can reduce data on any device in the same Windows domain as the machine on which it is installed.

NXPowerLite can be deployed to reduce data on SAN, NAS, and other file systems. At the time of writing, we do not know of any storage system on which NXPowerLite cannot reduce data, provided it is a member of the same Windows domain.

Customers have successfully deployed NXPowerLite to reduce data on the following devices:
• NetApp SAN
• Novell Netware SAN*
• An extensive range of NAS devices
• Local storage disks
* Windows Service configuration required: Please see Novell's website.

General Compatibility

Users / User's files

NXPowerLite is a completely transparent process to users, with specific features designed to minimize the chance that it will affect their everyday interactions with files. Users can continue to use the same tools and processes without interruption from NXPowerLite. Here’s how NXPowerLite achieves this:
• Last-accessed or last-modified dates of files are not altered
• Files that are in use are skipped
• Files that have recently been modified are skipped by default


NXPowerLite file reduction is a complementary technology, amplifying the compression achieved by deduplication. It works well with file types where deduplication is not effective and can be successfully deployed alongside any deduplication strategy.

Depending on the configuration of any active deduplication process, NXPowerLite will trigger and increase the activity from the deduplication process if it is enabled and active on the same data. NXPowerLite’s first cycle is likely to have the largest impact but subsequent NXPowerLite cycles should see this activity decrease dramatically.

To minimize the probability of conflicts, you may wish to configure deduplication such that NXPowerLite’s supported files (PDF, JPEG, Office Files & TIFF) are not deduplicated.

In case of adding a large amount of data to a new system, we advise that NXPowerLite is run prior to the deduplication process, or deduplication is disabled during NXPowerLite’s processing. This will ensure that the two processes are not competing for resources.


NXPowerLite works well with all of these technologies. The most important consideration is that NXPowerLite modifies a large number of files very rapidly, which might then trigger increased replication, mirroring, or backup activity. This effect will be amplified if the activity involves remote distributed locations over WAN.

The first time NXPowerLite is run it will generate the most file activity. We would recommend using NXPowerLite’s scheduling features to run it at quiet times and minimize the probability of conflicts and resource drains. NXPowerLite maintains its state and progress, so it can resume processing files after a scheduled pause, ensuring all the configured content is processed.


NXPowerLite is fully compatible with all anti-virus solutions. When deploying, please consider the increased activity that NXPowerLite will create. If your anti-virus solution employs on-demand scanning, please see this NXPowerLite support article for configuration advice.
