text: **3.7.4 iSCSI Extensions for RDMA (iSER)**
  
  IBM Spectrum Virtualize V8.2.1 introduced support for iSER host attachment for the Storwize 
  V7000 Gen2+ by using RoCE or iWARP transport protocol, depending on HBA hardware and 
  host platforms that provide the following components: 
  
  (cid:2) A fully Ethernet based infrastructure (no Fibre Channel) in the Data center 
  (cid:2) IBM SAN Volume Controller or Storwize inter-node communication 
  (cid:2) HyperSwap (SVC/Storwize) 
  
  The system supports node-to-node connections that use Ethernet protocols that support 
  remote direct memory access (RDMA) technology, such as RDMA over Converged Ethernet 
  (RoCE) or iWARP.
