Question
A customer has a Microsoft SQL environment that is recourse intensive. The SQL databases reside on SMB3.0 file shares on a separate pool of servers. The customer needs to improve IO performance and ensure that network latency is kept to a minimum while not affecting CPU use. Which technology should you recommend?
Options
- ARemote Dynamic Memory Access (RDMA) over Converged Ethernet (RoCE)
- BFlexibleLOM sockets with 10Gb uplinks
- CVirtual Extensible LAN (VXLAN) over layer 2 networks
- DTCP Offload HBA over 10 Gb ISCSI

Explanation
RDMA over Converged Ethernet (RoCE) -Dramatically increase data transfer efficiency with very low latencies for applications such as Microsoft Hyper-V Live Migration, Microsoft SQL and Microsoft Storage Spaces with SMB Direct 3.0. RDMA over Converged Ethernet (RoCE) reduces CPU utilization and helps maximize host VM density and server efficiency. Using SMB with RoCE, Hyper-V Live Migration is seven times faster than TCP/IP.
