Embodiments of the disclosure provide systems and methods for enabling disaster recovery from a source cluster to a target cluster in a multi-cluster cloud-computing environment. A domain cluster configures a replicated data volume to be updated with data from a data volume of the source cluster, wherein the replicated data volume resides in the target cluster; determines that the target cluster is to replace the source cluster as an active cluster; rebuilds, in the target cluster, a new container instance to replace the container instance on the source cluster; configures the container instance to utilize the replicated data volume in the target cluster; and discontinues recognition of the data volume and container instance on the source cluster as being authoritative.

Method and system for managing cloud resources

Provided herein are methods and systems for improved storage strategies for use of collections of storage resources, such as solid state drives, including in connection with a converged networking and storage node that may be used for virtualization of a collection of physically attached and/or network-connected storage resources.

Single-step configuration of storage and network devices in a virtualized cluster of storage resources

Techniques for using a cache to accelerate virtual machine (VM) I/O are provided. In one embodiment, a host system can intercept an I/O request from a VM running on the host system, where the I/O request is directed to a virtual disk residing on a shared storage device. The host system can then process the I/O request by accessing a cache that resides on one or more cache devices directly attached to the host system, where the accessing of the cache is transparent to the VM.

Transparent host-side caching of virtual disks located on shared storage

Methods and systems for data storage using solid state drives

Techniques for surfacing host-side flash storage capacity to a plurality of VMs running on a host system are provided. In one embodiment, the host system creates, for each VM in the plurality of VMs, a flash storage space allocation in a flash storage device that is locally attached to the host system. The host system then causes the flash storage space allocation to be readable and writable by the VM as a virtual flash memory device.

Techniques for surfacing host-side storage capacity to virtual machines when performing VM suspend or snapshot operations

Exemplary methods, apparatuses, and systems receive a command to overwrite or delete data stored within an allocated portion of a file system. In response to the command, an entry is added to a first data structure. A write command is received. The portion of the file system added to the first data structure is formatted for reallocation. In performance of the write command, the portion of the file system is reallocated. Portions of the file system are allocated from a second data structure when the second data structure includes a sufficient amount of space to satisfy the write command and from the first data structure when the second data structure does not include a sufficient amount of space. The second data structure includes free portions of the file system that have been formatted for allocation. The first data structure includes free portions that have yet to be formatted.

Inline garbage collection for log-structured file systems

Techniques for using a host-side cache to accelerate virtual machine (VM) I/O are provided. In one embodiment, the hypervisor of a host system can intercept an I/O request from a VM running on the host system, where the I/O request is directed to a virtual disk residing on a shared storage device. The hypervisor can then process the I/O request by accessing a host-side cache that resides one or more cache devices distinct from the shared storage device, where the accessing of the host-side cache is transparent to the VM.
