Brocade has brought much-needed enhancements to the IPv6 capabilities available in ServerIron ADX series with software release version 12.3. The details are a bit unclear as this blog entry is being written since the Brocade website still seems to have collateral related to release 12.2. The You-Tube announcement does reference a standards-based NAT64, which should be an implementation of the soon to be published RFC currently called draft-ietf-behave-v6v4-xlate-stateful, but there was no specific statement related to that.
