One of our customer willing to migrate his FAS2552 storage with 1Gb iSCSI to 10Gb iSCSI.
In order keep the cost low the picked switch would be DELL X4012 12x 10Gb SFP+ with original DELL Networkin 10Gb twinax DACs.
Thou I can find some partial (or) general information accross the web about the possible interoperability of different vendors' switches, DACs, etc; I cannot find any comforting information about wheter this combination would work or not. (NetApp interoperablity matrix don't even include the mentioned switch.)
If you have some statement or real-life experience, pls let me know.
