摘要： This invention is configured to create and use a special data structure containing a data storage device's identification information for a storage device that will be duplicated. Upon such duplication, the special data is stored in a predetermined location on another device receiving the copied data and a flag bit is set to indicate whether or not the information in the data structure should be used to respond to a host inquiry regarding the identification of the storage device. Without reconfiguring the host's operating software, the system employs a method to respond to and satisfy a host inquiry for the storage device's identification information by employing the special data structure. This is done to avoid host conflict errors that might result from a conflict between identification information being replicated from the storage device and the other storage device to where its data is copied.

摘要： A method and apparatus for enabling an on-line reconfiguration of striped data in a disk array storage device. A replicated copy of the striped logical device is made in parallel with host operations. A logical device with a new configuration is then substituted for access by the host application even before any data is transferred to locations within the newly configured logical device. Independent processes operating in this disk array storage device reconfigure the data transparently to any host operations while accommodating host I/O requests directed to locations in the new configuration.

摘要： A system and method for initializing large portions, or extents, of a mass-storage device in the background so that such overwriting processes do not significantly affect latency as experienced by a host. The method extends the use a system intended for background copying of data from a source extent to a destination extent to that of initializing an extent on a mass-storage device. It does so by causing the system to treat the defined extent as both a source extent and as a destination extent simultaneously.

摘要： Described are techniques for performing data storage optimizations. A data storage optimizer on a first data storage system connected to a set of other data storage systems receives performance classification information. The first data storage system includes a first set of storage devices of a first performance classification. The set of other data storage systems includes a second set of storage devices of a second performance classification different from the first performance classification. A write operation is received from the host to write first data to a target address of a virtually provisioned device. It is determined that physical storage is not currently allocated for the target address of the virtually provisioned device. A first portion of physical storage is allocated for storing the first data. The first portion of physical storage is included in a storage device of the second set having the second performance classification.

摘要： Synchronization of data layouts and resource utilizations at one or more remote replica sites with the workload and data tiering decisions being made at the primary site allows for an efficient and effective workload support transfer in the event of site failover from a primary site to a remote site. Relevant data access information about workload being supported at the primary site is collected and from that raw information, characterized data access information is generated that condenses the raw data access information or otherwise provides relevant encapsulated information about the raw data access information. The characterized data access information is transmitted to the one or more remote sites allowing each remote site to make its own independent decisions on how best to utilize its available resources to match the performance requirements currently being supported by the primary site.

摘要： A storage cloud enabled platform includes storage nodes and application nodes which are the part of the same operating environment. The storage nodes and computation nodes are interconnected inside platform via an interface to provide improved response time and high bandwidth paths for storage applications. The computation nodes may include virtual or non-virtual machines. The interface may support various protocols depending on desired ease of use and response time. For example, a standardized protocol such as SCSI could be used for ease of use and data safety, or a direct data placement protocol could be used to help maximize response rate.

摘要： Identifying data for placement in a storage system having a plurality of storage classes includes subdividing the data into portions, for each of the portions, independently determining at least one score for a particular portion based on a metric corresponding to access of the particular portion, where the at least one score for the particular portion is independent of scores for other ones of the portions, and identifying sub-portions of data for placement in a particular storage class based on the at least one score of a portion of data corresponding to the sub-portions. The at least one score may be based on short term access statistics and long term access statistics. The access statistics may include read misses, writes, and prefetches.

摘要： When migrating data, a first message is received at a target data storage system from a source data storage system. The target data storage system includes a data storage optimizer that performs automated data movement optimizations. The first message requests a reservation of a first amount of storage on a first storage tier for performing a data migration to migrate data from the source to the target data storage system. A first capacity limit of the first storage tier is reduced by the first amount thereby representing the reservation of the first amount of storage for performing the data migration. If the first storage tier does not include an amount of available storage of at least the first amount, processing is performed to increase the amount of available storage of the first storage tier.

摘要： Managing data in a storage system having a plurality of classes of storage includes determining an amount of data to be provided on at least one of the classes of storage according to a policy, dynamically setting a threshold according to the amount of data to be provided on the at least one of the classes or an expected performance based on the threshold, and placing data on particular classes of storage based on the threshold. Dynamically setting a threshold may include sorting data portions according to at least one score thereof and may include determining a particular score corresponding to the amount of data to be provided. The data portions may be provided in a histogram having a horizontal scale corresponding to a score value and a vertical scale corresponding to a number of data portions having a particular value.

摘要： Measuring access rates of a computer memory include subdividing the memory into subsections, monitoring access rates for each of the subsections, in response to a subsection having a relatively high access rate, subdividing the subsection into multiple subsections that are separately monitored, and, in response to at least two adjacent subsections having a relatively low access rate, merging the at least two subsections into a single subsection. Monitoring access rates may include monitoring at least one of the following operational parameters: number of data accesses, number of cache accesses, number of cache misses, number of read accesses, number of write accesses, and ratio of read accesses to write accesses. Two or more operational parameters may be used and the operational parameters may be weighted.
