iSCSI iSER Support

Support inputs

• Never saw any requests about this

Sales inputs

• RDMA (SMB Direct) and NFSoRDMA is much more common

Engineering inputs

• https://en.wikipedia.org/wiki/ISCSI_Extensions_for_RDMA

• There is SRP and iSER for RDMA, seems we want iSER first

• Will require IB, RoCE or iWarp

• Will need to validate performance gains make it a worthwhile effort

Competition Analysis

• QNAP does provide iSER and claims huge performance gains (https://www.qnap.com/en/how-to/tutorial/article/using-iscsi-extensions-for-rdma-iser-to-improve-the-performance-of-qnap-nas-with-vmware-esxi-or-vjbod )

What is the problem we are trying to solve?

• RDMA support with iSCSI for better performance

User Story

• Customer has a requirement for very high performance and low latency iSCSI for VMs workload. During configuration of iSCSI he will be able to select the interface (either globally or per target – to be defined)
