Key points of the webinar:

  • Discussing general facts about RDMA and iSER
  • Comparing performance of IT environments that use iSER and iSCSI: iSER vs. iSCSI. Fight!
  • iSER requirements and how the protocol can be enabled

We all know that there’s never much CPU resources. Especially, this claim is valid for CPU-hungry environments where hundreds of VMs are running. Ok, let’s say you are a VMware administrator trying to manage them, and you are looking for more resources to run some extra VMs. For that purpose, you should reconsider the role the network plays in your IT ecosystem. In order to streamline the existing resources utilization, enable iSER. This protocol allows offloading network I/O to RDMA hardware. All you need is replacing the iSCSI protocol with iSER and ensure that your hardware supports the protocol. Learn from this video how your IT ecosystem benefits from iSER.
