There are two main features that were impacted in RNOS 6.10.0: 1) removing antivirus for the 100 series and 2) removing disk spin down for the 12+ bay rackmount readynas.
Removing Anti Virus For 100 Series (RN102 / RN104) The minimum requirement for the current implementation of AntiVirus is exceeding the physical ram that is available in the 100 series units. There were a number of issues related to performance and software (application) stability that we are not able to resolve with the limitations in the available physical ram in these units.
Removing Disk Spin Down for 12+ Bay Rackmount ReadyNAS (RR2312 / RN3220 / RR3312 / RN4220 RR4312 / RR4360) The Disk Spin Down is primarily intended on the smaller units that are attempting to save some power from spinning disks. There are some power budget restrictions that we handle by staggering the disk spin up to provide a smooth transition from the disks in power saving mode to full power. This type of behavior does not scale very well when there are users attempting to use this feature with 12+ disks.
There are other improvements and bugfixes available in RNOS 6.10.0.
