As been blogged about Dennis, we’ve recently built a S2D cluster. While configuring the RDMA networks, I was wandering what the impact of the jumbo frame sizes were on the performance you can...Read More
After writing about a performance issue we had with HT (Hyper-threading) on Hyper-V hosts, and having seen this problem on more Hyper-V hosts. I thought I would give an update on the things I've...Read More
I'm gonna share a few things I've learned about the S2D configuration with the Intel P3600 in our Dell R730xd.
