Dell Technologies recommends that you follow the guidelines that are described in this section. Disable SMB SigningStorage Spaces Direct uses RDMA for SMB (storage) traffic for improved performance. When SMB signing is enabled the network performance of SMB traffic is significantly reduced. Update the hardware timeout for the Spaces portFor performance optimization and reliability, update the hardware timeout configuration for the Spaces port. Enable jumbo frames Enabling jumbo frames specifically on the interfaces supporting the storage network improve read/write performance of the Azure Stack HCI cluster. An end-to-end configuration of jumbo frames is required to take advantage of this technology. Configure jumbo frame by using the MTU configuration value "9014" bytes for the storage work endpoints. Antivirus exclusions Dell Technologies recommends you to plan appropriate antivirus exclusions as part of best practices.
