  • Patent number: 11397532
    Abstract: The technology described herein enables data storage across storage volumes having fewer features than the storage volumes otherwise would. In one example, a method includes, in a data access system, identifying first data for storage on physical storage volumes. Each of the physical storage volumes corresponds to respective ones of data channels and control channels. The method further includes segmenting the first data into data segments corresponding to respective ones of the data channels and transferring the data segments as respective bit streams over the respective ones of the data channels to the respective ones of the physical storage volumes. The method also includes providing real-time write control to the physical storage volumes over respective ones of the control channels. The real-time write control directs a process for how the physical storage volumes write the data segments.

  • Patent number: 11372769
    Abstract: The embodiments herein describe a multi-tenant cache that implements fine-grained allocation of the entries within the cache. Each entry in the cache can be allocated to a particular tenant—i.e., fine-grained allocation—rather than having to assign all the entries in a way to a particular tenant. If the tenant does not currently need those entries (which can be tracked using counters), the entries can be invalidated (i.e., deallocated) and assigned to another tenant. Thus, fine-grained allocation provides a flexible allocation of entries in a hardware cache that permits an administrator to reserve any number of entries for a particular tenant, but also permit other tenants to use this bandwidth when the reserved entries are not currently needed by the tenant.

  • Patent number: 11334498
    Abstract: A system and method for transferring data between a user space buffer in the address space of a user space process running on a virtual machine and a storage system are described. The user space buffer is represented as a file with a file descriptor. In the method, a file system proxy receives a request for I/O read or write from the user space process without copying data to be transferred. The file system proxy then sends the request to a file system server without copying data to be transferred. The file system server then requests that the storage system perform the requested I/O directly between the storage system and the user space buffer, the only transfer of data being between the storage system and the user space buffer.

  • Patent number: 11301396
    Abstract: Technologies for accelerated edge data access and physical data security include an edge device that executes services associated with endpoint devices. An address decoder translates a virtual address generated by a service into an edge location using an edge translation table. If the edge location is not local, the edge device may localize the data and update the edge translation table. The edge device may migrate the service to another edge location, including migrating the edge translation table. The edge device may monitor telemetry and determine on a per-tenant basis whether a physical attack condition is present. If present, the edge device instructs a data resource to wipe an associated tenant data range. The determinations to localize remote data, to migrate the service, and/or whether the physical attack condition is present may be performed by an accelerator of the edge device. Other embodiments are described and claimed.
