Re: ScaleIO RDMA

The current test configuration is 4 to 8 Skylake-based hosts, FusionIO PCIe, DC S3700 SSDs and Intel DC P3700 NVMe 2.5″ drives if the platform supports NVMe Over Fabrics, Mellanox ConnectX-3 40GbE, Mellanox 40GbE switching.

This is a PoC for running the following in a hyperconverged ecosystem:

– vSphere, KVM or Hyper-V virtualization platform

– Active Directory

– Exchange Server

– Microsoft Clustered File Services

– VMware Horizon or Citrix VDI

– Remote Desktop Services

– Oracle Databases

– ERP system

PVRDMA does apply to VMs but ScaleIO SDS is virtualized in vSphere.

The other option if it supported RDMA would be to completely dedicate and passthrough an RDMA-capable adapter to each SDS VM.

Don’t you have a substantial CPU and latency tax by going through the whole TCP stack ?
