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.

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: 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: Techniques for implementing dynamic base disk mirroring for linked clones are provided. In one set of embodiments, a first node in a distributed storage system can monitor a congestion level of a base disk residing on the first node, where the base disk is shared by a plurality of linked clones. Upon determining that the congestion level exceeds a threshold, the first node can send, to a second node, a request to create a mirror of the base disk on that second node. Upon receiving an acknowledgement from the second node that the mirror has been successfully created, the first node can update a mirror set associated with the base disk to include an entry identifying the mirror. The first node can then communicate the updated mirror set to one or more other nodes.

Abstract: Techniques for decoupling compute and storage resources in a hyper-converged infrastructure (HCI) are provided. In one set of embodiments, a control plane of the HCI deployment can provision a host from a host platform of an infrastructure on which the HCI deployment is implemented and can provision one or more storage volumes from a storage platform of the infrastructure, where the storage platform runs on physical server resources in the infrastructure that are separate from the host platform. The control plane can then cause the one or more storage volumes to be network-attached to the host in a manner that enables a hypervisor of the host to make the one or more storage volumes available, as part of a virtual storage pool, to one or more virtual machines in the HCI deployment for data storage.

Abstract: A virtualization technique, in accordance with one embodiment of the present invention, includes emulating the small computing system interface (SCSI) protocol to access a virtual SCSI storage device backed by a file stored on network attached storage (NAS).

Abstract: The replication of a group of data sets is coordinated into a single schedule based on the recovery point objective (RPO) of each data set. The resulting generated schedule satisfies each data set's RPO requirements and minimizes bandwidth use. If necessary bandwidth exceeds available bandwidth, the resulting generated schedule attempts to best satisfy each data set's RPO requirements given the available bandwidth.

Abstract: In one embodiment, a method of processing data in a network with multiple proxy caches, includes: pushing cached data in a first proxy cache to at least one other proxy cache in a cluster configuration; caching the data from the first proxy cache; and permitting a client to access the data in the at least one other proxy cache in the cluster configuration. In another embodiment, a method of processing data in a network with multiple proxy caches, includes: providing a snapshot replica from a first server to second server; and permitting a proxy cache to access the second server for data in the snapshot replica, in response to a disconnect operation of the first server.
