Does data locality matter? My Perspective on Windows Server 2016 Storage Spaces Direct and RDMA
With the uprise in Hyperconverged technology it is interesting to see how the different vendors in the market has embraced different architectures in their implementation . I’ve previously blogged about how VMware, Microsoft and Nutanix has done this –> http://msandbu.org/storage-warshci-edition/
Now therefore I decided to dig a bit deeper into the way Microsoft has implemented their hyperconverged infrastructure solution called Storage Spaces Direct.
Now for those that are not aware of that new feature, it is a further improvement of Storage Spaces which came in 2012, which allowed us to create a virtual disk based upon one of more physical disks using different “RAID”like features like mirroring, parity or striping. In 2012 R2 they came with improved performance and new features like tiering for instance.
Fast forward to 2016, and we have seen that the market has changed with VMware, Nutanix been in the hyperconverged space for a while and Microsoft soon to be taking the step into this market. Now unlike VMware and Nutanix, Microsoft recommends that if you use their hyperconverged solution that you have a RDMA based backend network.
