The support of RoCE v2 is subject to qualified devices on the VMware Hardware Compatibility Guide. This results in lower compute overhead and improved storage performance. A hyperconverged architecture is ideal for RDMA, and vSAN 7 Update 2 introduces the support of RDMA over Converged Ethernet version 2 (RCoEv2). Clusters will be able to automatically detect the support of RDMA, which will deliver the potential for improved application performance and improved ROI through increased consolidation ratios. Remote Direct Memory Access (RDMA) is a technology that allows systems to bypass the CPU and send data with lower latency and compute overhead. Once data is fully re-synchronized, DRS will move the VM state to the desired site in accordance with DRS rules. This improvement can dramatically reduce unnecessary read operations occurring across the ISL, and free up ISL resources to continue with its efforts to complete any re-synchronizations post-site recovery. And finally, vSAN 7 Update 2 also increases the maximum host count to 40. vSAN 7 Update 2 introduces integration with data placement and DRS so that after a recovered failure condition, DRS will keep the VM state at the same site until data is fully re-synchronized, which will ensure that all read operations do not traverse the inter-site link (ISL). Stretched cluster configuration must account for not only a variety of failure scenarios but recovery conditions. vSAN file services is a powerful solution for edge and ROBO file needs. VSAN files services can now support stretched cluster and 2-node configurations. HCI mesh demonstration video Enhanced File Services Scalability has also been improved, where the number of hosts connecting to a remote vSAN datastore has been increased to 128. One of the most interesting capabilities, as it relates to HCI Mesh, is the integration with storage policies. When defining a storage policy, an administrator will be able to define the types of data services they are interested in (such as Deduplication and Compression, or Data-at-rest Encryption). Most importantly, HCI Mesh compute clusters do not need any vSAN licensing. In vSAN 7 Update 2, traditional vSphere clusters can mount a remote vSAN datastore. HCI Mesh compute clusters can consume storage resources provided by a remote vSAN cluster, in the same way that multiple vSphere clusters can connect to a traditional storage array. HCI Mesh compute clusters use native vSAN protocols for maximum efficiency and affords the customer the ability to easily meet a broad variety of use cases. ![]() VMware introduces a significant new capability to vSAN HCI Mesh.
