strange situation here. I noticed that HOTADD transport protocol is faster than SAN transport in one of our environments. Storage is a NetApp FAS8020 connected 4x with 10GBit/s Ethernet to a Cisco Nexus switch. I have one VBR 9.5 U2 server running on Windows Server 2012R2, equipped with one 10GBit/s interface into the iSCSI network, which runs over the Cisco Nexus switch.
If I use SAN transport, I get around 235MB/s throughput rate using the VBR server as proxy allowing 1 concurrent task and a repository limited to 1 task.
When I use HOTADD transport (Hotadd proxy is a Windows 2012R2 Server with 4 vCPUs, 4GB RAM and a vNIC with 10GBit/s), I get around 470MB/s throughput. Proxy and repository are limited to 1 concurrent task here as well.
Anybody else with such a behaviour?
