Work: Vplex ============================== EMC vplex is the next-generation solution for block-level virtualization and data mobility within, Alibaba SS, and between data centers. EMC vplex provides storage Federation by aggregating storage arrays that can be located either in a single data center or multiple data centers.

, the storage of the service amount is locked, wait until the data link is restored, and the two array data is restored to normal after the synchronization is completed. So, what happens if the arbitration disk fails? Very simple, two stores are locked and no service is provided. After all, the integrity of the data is the most important.what does the quorum server in the diagram do? As the name implies, it is a server or virtual machine, which runs a dedicated program that provides IP Protocol-

The new version adds two more features to virtualization and better integrates the capabilities of VNX and VMware, and this article details the Vaai for multiple snapshots of NFS. VASA (vstorage API for Storage Awareness) Vaai for NFS multiple snapshots (vstorage API for Array integration) Solution: Vaai Function Introduction The array integrated storage API (the Vstorage API for array integration, abbreviated VAAI) is the API that VMware

capacity properties of LUNs and file systems, such as whether to enable fast VP, or enable compression, to manage storage more efficiently, and to easily view, monitor the running state and capacity alarms of VNX storage in a VM environment. Vaai Function Introduction The array integrated storage API (the Vstorage API for array integration, abbreviated VAAI) is the API that VMware provides to storage device vendors. On the storage side, delegating some of the capabi
