The iSCSI-R3 has not been announced for this, only FC to the storage capabilities (although just got word that this maybe sooner) – check the updates next week. DSS currently has this now with 1.18 update. As for the driver issue contact support to ask them for an update?
Concerning the 15th update for DSS, this will be another couple of days as we are still testing in QA. For mailing send email to info@open-e.com to placed on a mailing list.
