Nope - at the time, the 4100
was the "bigger and better" unit. Unlike all of the other SnapOS-based units, it uses multiple masters for its 4 drives (2 Promise controllers). All of the other SnapOS units use the chipset drive controllers.
Snap didn't want to do LBA48 on any of the SnapOS stuff, but the 1100/2200 wouldn't be marketable as 120GB units. So they were forced to add LBA48 so they could sell a 250GB unit.
There was no "evil intent" to specifically not support LBA48 on the 4100 - it is just that they added support in the Intel chipset driver and didn't do it for the Promise chipset used exclusively in the 4100. It didn't help that Promise told them that the chipset didn't support LBA48 (not true, as FreeBSD, Linux, etc. support LBA48 on it).
It sat there as a dead issue until I asked them to quote me a price to add it. At that point, they decided they didn't have the engineering resources to allocate to it, as all of the work was being done on GuardianOS.
So I sold all my 4100's and started building my own servers (info
here). But I still don't think there's an evil conspiracy to keep LBA48 off the 4100's.
