Deploying Storage Spaces Direct – Part 42 – HPE RDMA Issues Mellanox CX3-Pro Prod Issue #StorageSpacesDirect #HPE #S2D @MellanoxTech

Hey Storage Spaces Direct Fans, Today seemed to have finally resolved the case of the jobs that were stuck on our Production 4 x Node S2D Cluster running on HPE DL380 G9’s and Mellanox CX3-Pro NICS. We had been banging our heads against the wall and I decided to re-test our RDMA Configuration using the script mentions in an earlier post called Test-RDMA.ps1.

Hey Storage Spaces Direct Fans, Today I deployed a 2x Node Storage Spaces Direct configuration for a customer. They purchased 2 x HP DL380 G9’s, P840 Controllers (HBA’s), 256GB RAM, 6 x Intel 1.6 TB SSD, Mellanox CX-3 Pro network adapters, and connected to their existing Cisco Meraki Switches.
