We have an Isilon NL400 cluster with a failed 3TB drive (HDD, SEAGATE ST3000NM0063). It is my understanding that this drive is end of life. A replacement option would be a 4TB drive (Seagate Exos 7E8 ST4000NM003A - hard drive - 4 TB - SAS 12Gb/s).

Are there any limitation to these nodes that will prevent a 4TB drive functioning properly? Also, we are running OneFS 8.1.2.0. Will we have an issue where licensing is concerned? I know the Gen6 Isilon have a capacity license piece to it.

Thanks for your guidance.
