Does the T10W have the same failover ability as does the T20?
It depends on what type of failover you're talking about.
-T10/T10-W is not capable of being in a FireCluster, so it can't fail over to a different T10.
-If the T10-W has a feature key with Fireware Pro, it can do multi-WAN failover. Back when the T10 was being produced, this wasn't a standard feature, so you'll need to check to see if yours has it.
If you look in Policy Manager under Setup -> Feature Key or in WebUI under System -> Feature Key you'll see a line that says WAN Failover: Enabled. In older versions the line will read "Feature: XTM_PRO"
