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 ?
