  • Patent number: 11347409
    Abstract: A primary storage system appends a red-hot data indicator to each track of data transmitted on a remote data facility during an initial synchronization state. The red-hot data indicator indicates, on a track-by-track basis, whether the data associated with that track should be stored as compressed or uncompressed data by the backup storage system. The red-hot data indicator may be obtained from the primary storage system's extent-based red-hot data map. If the red-hot data indicator indicates that the track should remain uncompressed, or if the track is locally identified as red-hot data, the backup storage system stores the track as uncompressed data. If the red-hot data indicator indicates that the track should be compressed, the backup storage system compresses the track and stores the track as compressed data. After the initial synchronization process has completed, red-hot data indicators are no longer appended to tracks by the primary storage system.

  • Publication number: 20220011942
    Abstract: Techniques for determining service levels may include receiving an I/O operation at a target port of a data storage system, where the I/O operation is sent from an initiator port of a host and directed to a storage object in a first storage group. The initiator port may be included in a first initiator group and the target port may be included in a first port group. The I/O operation may be assigned a service level using a table of a service levels specified for different triples. Each triple may identify an initiator groups, a storage group and a port group. Assigning the service level may include determining a first of the triples that matches the first storage group, the first initiator group and the first port group, wherein the first triple is associated with the service level.

  • Publication number: 20210406678
    Abstract: Techniques for predicting states may include: receiving data sets of counter values, wherein each counter values denotes a number of times a particular code flow point associated with the counter value is executed at runtime during a specified time period; receiving images generated from the data sets; labeling each of the images with state information, wherein first state information associated with a first image indicates that the first image is associated with a first error state of a system or an application; training a neural network using the images to recognize the first state; receiving a next image generated from another data set; and predicting, by the neural network and in accordance with the next image, whether the system or the application is expected to transition into the first state. In at least one embodiment, the foregoing processing may optionally use matrices generated from the data sets rather than images.

  • Patent number: 11128708
    Abstract: A method is used in managing remote replication in storage systems. The method monitors network traffic characteristics of a network. The network enables communication between a first storage system and a second storage system. The method predicts a change in at least one of an application demand of an application of a set of applications executing on the first storage server and a network state of the network, where the set of applications have been identified for performing a replication to the second storage system. Based on the prediction, the method dynamically manages replication of the set of applications in accordance with a performance target associated with each application.

  • Patent number: 10853246
    Abstract: Techniques for processing data may include: determining a first amount denoting an amount of write pending data stored in cache to be redirected through storage class memory (SCM) when destaging cached write pending data from the cache; performing first processing that destages write pending data from the cache, the first processing including: selecting, in accordance with the first amount, a first portion of write pending data that is destaged from the cache and stored in the SCM and a second portion of write pending data that is destaged directly from the cache and stored on one or more physical storage devices providing back-end non-volatile physical storage; and subsequent to storing the first portion of write pending data to the SCM, transferring the first portion of write pending data from the SCM to the one or more physical storage devices providing back-end non-volatile physical storage.

  • Patent number: 10613998
    Abstract: Techniques for processing I/O operations may include: receiving an I/O having an associated expected execution time (EET) and I/O service level; selecting, in accordance with the EET and service level of the I/O, a first I/O queue from multiple pending I/O queues; inserting the I/O into the first I/O queue; and performing I/O shifting. I/O shifting may include shifting I/Os from one pending I/O queue to another that is ranked immediately higher than the one pending I/O queue. The multiple I/O queues may be ranked from a highest priority queue to a lowest priority queue. I/O shifting may shift I/Os from the highest priority queue to execution and shifting I/Os from another queue into the highest priority queue. I/O shifting is subject to remaining credits available of the multiple I/O queues and time distance between source and target queues.

  • Patent number: 9946465
    Abstract: Described are techniques user to determine expected service levels. A first set of one or more data portions are selected from one or more devices forming a first device set. The first set of data portions are stored on physical storage of a physical device set of one or more physical devices having an unknown service level expectation. I/O operations directed to the first set of data portions are received and serviced for a time period. First information is collected that characterizes performance of the physical device set during the time period. In accordance with the first information and using an adaptive learning technique, a first service level expectation for servicing I/Os directed to the physical device set is determined.

  • Publication number: 20140130929
    Abstract: Flexible, helically corrugated, seamless pipes and tubular conduits of indeterminate length. In some embodiments, these pipes or conduits are formed by a continuous corrugating process on a corrugator. In some embodiments, the pipes are collapsible and are configured to remain in the collapsed and un-collapsed state without the application of external force. Also disclosed are helical tubes include corrugations that follow a counterclockwise path and corrugations that follow a clockwise path. Also disclosed are dual helical tubes with helical corrugations configured such that a portion of each corrugation follows a counterclockwise rotation and another portion of the corrugation follows a clockwise rotation.
