Storage Spaces Direct is a scalable and cost-effective storage solution for VMware vSphere environments

A cluster of Windows Server nodes can use the software-defined storage (SDS) solution Storage Spaces Direct (S2D) to pool their local storage drives into a single, highly available storage pool. The creation and management of virtual discs (VDisks) with different sizes and performance characteristics may then be done using this storage pool. The Datacenter and Standard editions of Windows Server 2022, 2019 and 2016 come with Storage Spaces Direct (S2D).

Virtual Machine Identification (VM-ID) in Fibre Channel: A Comprehensive Overview

Virtual Machine Identification (VMID or VM-ID) is a technology for tracking virtual machine I/O between virtual machine and SAN target. VM-ID can be used by hypervisor and FC switch to trace generated I/O by specific VM. As result, we can optimize whole SAN area for VI workload and non-VI workloads would be achieved.

Fibre Channel Trunking (Aggregation): Better Performance, Higher Bandwidth (>1 Tb/s)

We are all knowing LACP on ethernet network but Fibre Channel and SAN network providing multipathing I/O by using logical and physical paths as single device on operating system and also using path selecting policies for using I/O paths optimized. But if server using 16Gb/s FC HBA, so there is no bandwidth aggregation. Server can generate bandwidth for each port up to maximum speed of port and also path selecting has performance impact of server when large paths are presented to server. Months before, I was thinking about FC port aggregation and did many searches but I didn’t find anything until now.
