Techniques for extending the capabilities of computing environments and/or systems are disclosed. A scalable and dynamic external computing resource can be used in order to effectively extend the internal computing capabilities of a computing environment or system. The scalable and dynamic external computing resource can provide computing resources that far exceed the internal computing resources, and provide the services as needed, and in a dynamic manner at execution time. As a result, a computing device may function with relatively limited and/or reduced computing resources (e.g., processing power, memory) but have the ability to effectively provide as much computing services as may be needed, and provide the services when needed, on demand, and dynamically during the execution time.

A data storage system having a slow tier and a fast tier maintains hot data on the fast tier by migrating data from the slow tier to reserve space on the fast tier as data becomes hot over time. The system maintains a reserve space table and performs a mass migration of data from the fast tier to the slow tier. Data migration is frequently unidirectional with data migrating from the slow to the fast tier, reducing overhead during normal operation.

Needless migration of duplicate file data is avoided by recording in a database a record of migration of a first instance of a replicated file from a source file server to a target file server. When migrating a subsequent instance of a replicated file to the target file server, the database is searched for a record of replication of a first instance of the replicated file to the target file server. If such a record is found, the subsequent instance is replicated by sending from the source file server to the target file server attributes of the subsequent instance of the replicated file and an identification of the previously migrated data of the replicated file without re-transmission of the previously migrated data of the replicated file.

A method for configuring a transaction-based host environment for migration to a new system platform is described. The method comprises the steps of providing at least one database of a first type and at least one database of a second type, which have different migration behaviour, on the previous system platform. Further provided is a first type of transaction which accesses both the first type of database and the second type of database on the previous system platform. For preparing the migration, the first type of transaction is replaced in the host environment by a second type of transaction and a third type of transaction, wherein the second type of transaction accesses only the first type of database and the third type of transaction only the second type of database. The method additionally comprises initiating transactions of the second and third type on request for a transaction of the first type from a decentralised environment.

An improved duty cycle, increased effective bandwidth, and minimized power consumption are attained in a system for data migration between a compute cluster and disk drives by inclusion of a buffer node coupled to the compute cluster to store data received therefrom in a random fashion. The buffer node signals the computer nodes to promptly return from the I/O cycle to the computing state to improve the duty cycle of the device. The system further includes a storage controller which is coupled between the buffer node and the disk drives to schedule data transfer activity between them in an optimal orderly manner. The data transfers are actuated in the sequence determined based on minimization of seeking time and tier usage, and harvest priority, when the buffer node either reaches a predetermined storage space minimal level or a predetermined time has elapsed since the previous I/O cycle. The storage controller deactivates the disk drives which are not needed for the data transfer. Since the writing on the disk drives is conducted in the orderly manner, the system avoids the usage of excessive number of disk drives.

The storage control device of the present invention performs data migration without any increase of the load on a NAS control unit. A volume based on a FC disk and a volume based on a ATA disk are joined together, so as to create one virtual volume. An update manager monitors updating of the high speed region, and creates update bitmaps. And the update manager calculates the OR of the update bitmaps, thus creating a non-updated bitmap for detecting segments which have not been updated for a predetermined time period. Based on this non-updated bitmap, a migration controller creates a migration subject bitmap by extracting segments which are to be subjects for migration. And a migration executant performs data migration for the migration subject segments one at a time or several together, based on this migration subject bitmap.

A data migrating system and method are provided in which a Burst Buffer Network Aggregator (BBNA) process is configured either on the File Servers or on the File System's dedicated I/O nodes to coalesce data fragments stored in participating Burst Buffer nodes under the direction of a primary BB node appointed by a data generating entity prior to transfer of the full data stripe into the File System. The “write” request in the form of a full data stripe is distributed into a plurality of data fragments among participating BB nodes along with corresponding metadata. The primary BB node gathers the metadata from the participating BB nodes, sends the metadata list to the BBNA unit, responsive to which the BBNA unit allocates a buffer sufficient to store the full data stripe, and transfers data fragments from participating BB nodes into the full data stripe buffer, thereby coalescing the data fragments into the full data stripe, which is subsequently transferred from the buffer in the BBNA unit into the File System.

A system for communicating between stations which are at a number of different locations in a large building in which radio transmission is achieved through corridors or stairwell shafts or through windows along a zone outside of the building or any combination thereof. This system employs communication through spread spectrum transceivers and a set of directional antennas. At each station, one of the antennas is circular polarized and the other is linear polarized with a horizontal electrical component to facilitate reflection off the floors of the building. The spread spectrum is a hybrid frequency hopped and direct sequence modulated signal.

The migration of telephone services by a telecommunications carrier from a PSTN to an IP network entails that problem that when it is not possible for some telephone subscribers to migrate to the IP network due to the types of their telephone lines or services they subscribe to, other subscribers also cannot migrate to the IP network until the former subscribers migrate to the IP network.

The present invention provides a media gateway that enables a gradual transition from a PSTN to an IP network on a subscriber-by-subscriber basis or on a service-by-service basis so that a telecommunications carrier can efficiently migrate its subscribers while continuing to provide the services the subscribers currently use and reducing burdens on the subscribers.

The memory controller may be built on the basis of FPGAs, thus providing an economical and miniature system.
