E8 Storage Systems Assigned Four Patents

Lockless distributed redundant storage and NVRAM
caching of compressed data in highly-distributed shared topology
E8 Storage Systems Ltd., Ramat Gan, Israel, has been assigned a patent (9,529,542) developed by Friedman, Alex, Hadera, Israel, Pinhas, Barak, Givatayim, Israel, and Budilovsky, Evgeny, Yehud, Israel, for a “lockless distributed redundant storage and NVRAM caching of compressed data in a highly-distributed shared topology with direct memory access capable interconnect.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system for data storage includes multiple servers, which are configured to communicate over a network with multiple multi-queue storage devices and with at least one storage controller, to store on the storage devices compressed data belonging to a user volume, to specify storage locations, in which the compressed data is stored on the storage devices, in a shared data structure that is shared and modified by the servers using remote direct memory access, and to coordinate access to the compressed data by the servers by querying the shared data structure, without executing code on a processor of the storage controller.“

The patent application was filed on March 31, 2016 (15/086,102).

Lockless distributed redundant storage and NVRAM cache in
highly-distributed shared topology with direct memory access capable interconnect
E8 Storage Systems Ltd., Ramat Gan, Israel, has been assigned a patent (9,525,737) developed by Friedman, Alex, Hadera, Israel, for a “lockless distributed redundant storage and NVRAM cache in a highly-distributed shared topology with direct memory access capable interconnect.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for data storage includes, in a system that includes multiple servers and multiple multi-queue storage devices that communicate over a network, accumulating data blocks by a server in a Non-Volatile Random-Access Memory (NVRAM) cache that is accessible to the servers and to the storage devices, by sending the data blocks from the server to the NVRAM cache using remote direct memory access, so as to form one or more stripes. The stripes are transferred from the NVRAM cache to respective server-specific queues on the storage devices. Another server is prevented from causing inconsistency in the data blocks, by querying a data structure, which is shared and modified by the servers using remote direct memory access, and which specifies storage locations of the data blocks.“

The patent application was filed on February 4, 2016 (15/015,157).

Distributed RAID over shared multi-queued storage devices
E8 Storage Systems Ltd., Ramat Gan, Israel, has been assigned a patent (9,521,201) developed by Ori, Zivan, Tel Aviv, Israel, for a “distributed raid over shared multi-queued storage devices.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for data storage includes, in a system that includes multiple servers and multiple storage devices, holding in a server a definition of a stripe that includes multiple memory locations on the storage devices, to be used by the servers for storing multiple data elements and at least a redundancy element calculated over the data elements. One or more of the data elements in the stripe are modified by the server, by executing in the storage devices an atomic command, which updates the redundancy element to reflect the modified data elements only if a current redundancy element stored in the storage devices reflects the multiple data elements prior to modification of the data elements, and storing the modified data elements in the storage devices only in response to successful completion of the atomic command.“

The patent application was filed on January 18, 2016 (14/997,600).

Snapshots and thin-provisioning in distributed storage over shared storage devices
E8 Storage Systems Ltd., Ramat Gan, Israel, has been assigned a patent (9,519,666) developed by Friedman, Alex, Hadera, Israel, for a “snapshots and thin-provisioning in distributed storage over shared storage devices.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for data storage includes, in a system that includes one or more storage controllers, one or more servers and one or more storage devices, defining one or more data structures that represent thinly-provisioned user volumes used by the servers in storing data on the storage devices. One or more of the data structures are shared among the storage controllers and the servers. One or more of the user volumes are accessed by the servers, using the shared data structures and without executing code on the storage controllers.“

The patent application was filed on April 28, 2015 (14/697,653).
