But this is noted from the online help in DSS and in the manual on page 58. Also in many areas of the website http://www.open-e.com/site_media/dow...ication_IG.pdf

Online help section:

Failover quick start guide:

* Set up volume replication on the primary and the secondary servers. Please note that all volume replication restrictions apply here (volumes cannot be larger than 4TB, they need to be exactly of the same size and need to have the same I/O method selected [file I/O or block I/O]).

DSS Manual:

Maximal NAS (N), iSCSI (I) and Fibre Channel (FC) volume size (with
replication) is limited to 4193120MB (megabytes).
