Abstract: An example method of providing a common volume (cVol) datastore for virtual machines (VMs) managed by a hypervisor in a virtualized computing system is described. The method includes: mounting, by the hypervisor, a network file system share of a common volume (cVol), the cVol stored in shared storage of the virtualized computing system, the network file system share storing metadata for the VMs; creating a file system for the cVol datastore backed by the network file system share; routing file operations targeting the metadata to the file system for the cVol datastore; and routing file operations targeting virtual disks of the VMs to an object storage pool of the cVol based on descriptors in the metadata that point to objects backing the virtual disks.

Abstract: An example method of providing a common volume (cVol) datastore for virtual machines (VMs) managed by a hypervisor in a cloud computing system includes: mounting, by the hypervisor in cooperation with a network file system server, a network file system share of a common volume (cVol), the network file system share storing metadata for the VMs; creating a file system container backed by the network file system share; routing file operations targeting the metadata to the file system container; attaching cloud volumes as devices on a host of the hypervisor, the cloud volumes referenced by descriptors in the metadata; and routing file operations targeting virtual disks of the VMs to the devices.

Abstract: The disclosure herein describes storing data using a capacity data storage tier and a smaller performance data storage tier. The capacity data storage tier includes capacity data storage hardware configured to store log-structured leaf pages (LLPs), and the performance data storage tier includes performance data storage hardware. A virtual address table (VAT) includes a set of virtual address entries referencing the LLPs. A tree-structured index includes index nodes referencing the set of virtual address entries of the VAT. Data to be stored is received, and at least a first portion of metadata associated with the received data is stored in the LLPs using the VAT, and at least a second portion of metadata associated with the received data is stored in the performance data storage tier. The architecture reduces space usage of the performance data storage tier.
