I am new to the iSER.<br>
On "<a href="https://openib.org/tiki/tiki-index.php?page=iSER"
eudora=autourl> https://openib.org/tiki/tiki-index.php?page=iSER</a>", it
is said that iSER currently contains initiator only (no target). Will the
target come out later? How did they test the iSER initiator without a iSER
target?<br>
Could you give some explaination?<o:p></o:p></span></font></p>

>From a practical perspective, there are very few iSCSI targets shipping
today. Most people had envisioned iSER over IB to a gateway Ethernet
device since native IB storage is also quite rare in terms of real
product. For many of us, our push for iSER over IB was to replace SRP
which has a deficient ecosystem thus not really used beyond some basic Fibre
Channel gateway cards. <br>
