Abstract

Remote Direct Memory Access (RDMA) enables a host to make a subset of its memory directly available to a remote host. RDMA is available on standard Ethernet-based networks by using the RDMA over Converged Ethernet (RoCE) interface. The RoCE network protocol is an industry-standard initiative by the InfiniBand Trade Association.

This IBM® Redpaper publication describes, how to set up RoCE to use within an IBM Spectrum® Scale cluster and IBM Elastic Storage® Systems.

This book is targeted toward technical professionals (consultants, technical support staff, IT Architects, and IT Specialists) who are responsible for delivering cost-effective storage solutions with IBM Spectrum Scale and IBM Elastic Storage Systems.
