Probabilistic deduplication-aware workload migration

A computing method includes running, on a plurality of compute nodes, multiple workloads that access respective sets of memory pages. Respective bitmaps are calculated for at least some of the workloads, wherein (i) a bitmap of a workload is statistically indicative of a cardinality of the set of memory pages used by the workload, (ii) a union of two or more bitmaps is statistically indicative of the cardinality of a union of the sets of memory pages used by the two or more corresponding workloads, and (iii) an intersection of first and second bitmaps is statistically indicative of an overlap between respective first and second sets of memory pages used by the corresponding workloads. ...

Using access-frequency hierarchy for selection of eviction destination

A method includes, in a computing system in which one or more workloads access memory pages in a memory, defining multiple memory-page lists, and specifying for each memory-page list a respective different scanning period. Access frequencies, with which the memory pages are accessed, are estimated continually by periodically checking the memory pages on each memory-page list in accordance with the scanning period specified for that memory-page list, and re-assigning the memory pages to the memory-page lists based on the estimated access frequencies. ... Strato Scale Ltd

Ordering schemes for network and storage i/o requests for minimizing workload idle time and inter-workload interference

A method includes receiving, from one or more workloads that are processed by one or more processors, requests to access data over a communication network or on a storage device. An order is defined among the requests, in accordance with a criterion that aims to minimize an overall idle time of the one or more processors in processing the multiple workloads. ... Strato Scale Ltd

Synchronization of snapshots in a distributed storage system

A method includes storing data generated in a source node by sending write requests to multiple destination nodes. The destination nodes are requested to create snapshots of the data. ... Strato Scale Ltd

Fast initiation of workloads using memory-resident post-boot snapshots

A method includes, in a computing system including one or more compute nodes that run workloads, booting a workload of a given type, and creating a post-boot snapshot of the workload at a point at which the workload completed booting but did not yet begin running user applications. In response to a request to initiate a new workload of the given type, the new workload is initiated starting from the post-boot snapshot.. ... Strato Scale Ltd

Reducing short-packet overhead in computer clusters

A method includes, in a computing system that includes multiple compute nodes that run workloads and are connected by a network, establishing a dedicated transport control protocol (tcp) connection over the network between a first compute node and a second compute node. Packets, which originate from one or more source workloads on the first compute node and are destined to one or more destination workloads on the second compute node, are identified and queued in the first compute node. ... Strato Scale Ltd

Exploiting node-local deduplication in distributed storage system

Data deduplication is carried out in a storage system in which a set of volumes of data is distributed among a plurality of servers. The technique comprises computing a similarity metric among volumes of the set, making a determination that a difference in the similarity metric is less than a predetermined threshold value. ... Strato Scale Ltd

Resilient post-copy live migration using eviction to shared storage in a global memory architecture

A method includes, in a computing system that includes at least first and second compute nodes, running on the first compute node a workload that uses memory pages. The memory pages used by the workload are classified into at least active pages and inactive pages, and the inactive memory pages are evicted to shared storage that is accessible at least to the first and second compute nodes. ... Strato Scale Ltd

Live migration of virtual machines that use externalized memory pages

A method includes running a virtual machine (vm) on a first compute node in a plurality of compute nodes that communicate with one another over a communication network. The vm is migrated from the first compute node to a second compute node in the plurality by generating, for memory pages accessed by the vm, page transfer state of one or more local memory pages that are accessed locally on the first compute node, and of one or more externalized memory pages whose access is not confined to the first node. ...
