LONDON & SANDTON, South Africa--(BUSINESS WIRE)--Cloudian, Inc., a leading provider of hybrid cloud object storage systems has announced that Sithabile Technology Services (STS), a South African data management solutions business, has adopted Cloudian HyperStore to support its backup, recovery and archiving services. Sithabile required a flexible solution to store multi-petabyte levels of unstructured data, with full public cloud compatibility and easy management for long-tem data retention. Having previously used a Scality-based solution, Sithabile also considered options from IBM Cloud Object Storage, SwiftStack and HPE before selecting Cloudian HyperStore. Businesses in South Africa are keen to take advantage of cloud services, but with tight data sovereignty laws many organisations have petabytes of data that cannot leave the country. With Cloudian, Sithabile customers can now securely utilise public cloud offerings for specific data types, while using its locally based services for data that must remain in South Africa - all through a single, simple interface. “We previously used Scality, but experienced S3 compatibility issues that caused service interruptions. Furthermore, their solution lacked multi-tenancy, a key feature for us. Cloudian provides us with the S3 compatibility, features, and performance our customers demand,” said Richard Tatham, Sitahbile’s GM, cloud services. “We have now deployed Cloudian, and our services are running better than ever.” Jon Toor, CMO at Cloudian explains, “More and more service providers count on Cloudian for their data storage services. Only Cloudian offers the full suite of features service providers need, including billing, quality of service controls, and multi-tenancy. Furthermore, only Cloudian offers an S3 compatibility guarantee, which gives them confidence that Cloudian will always work with their customer’s applications.” Sithabile currently owns one data centre in Johannesburg, and following increased customer demand is planning to open a second in Cape Town in 2017 where Cloudian HyperStore will also be deployed. Founded in October 2004, Sithabile Technology Services (STS), a proudly empowered company, is a specialist provider of complete data management solutions, which combine industry-leading consulting and engineering expertise with appropriate hardware, software and cloud technologies. STS’ goal is to meet the requirements of South African businesses for regulatory-compliant backup, recovery and archiving solutions from edge to core using the most advanced technologies available today. http://www.sithabile.co.za/ Based in Silicon Valley, Cloudian is a leading provider of hybrid cloud object storage systems. Our flagship product, Cloudian HyperStore, enables service providers and enterprises to build reliable, affordable and scalable hybrid cloud storage solutions.

A method of testing a target electronic device implemented in a configurable integrated circuit device includes receiving a baseline design for the target electronic device in a hardware description language, establishing a fault model for the particular configurable integrated circuit device, synthesizing the fault model in the hardware description language, embedding the synthesized fault model into the baseline design to create a modified baseline design in the hardware description language which enables one or more targeted signals to be selectively corrupted, creating a fault model enabled target device on the particular configurable integrated circuit device using the modified baseline design, performing a number of fault injection experiments on the fault model enabled target device, wherein each fault injection experiment includes causing at least one of the one or more targeted signals to be corrupted within the fault model enabled target device.

An embodiment of a power supply includes an input node, a converter stage, and an outlet. The input node is operable to receive an input AC signal having peak portions and non-peak portions. The converter stage is operable to generate a DC power signal from the input AC signal and to cause a first current to be drawn from the input node during at least the non-peak portions of the input AC signal. And the outlet is operable to carry the DC power signal. For example, such a power supply may be installed in a facility such as a residence, office building, or manufacturing plant, or the facilitys existing power supply may be retrofitted, to provide one or more power outlets that each carry a respective power-factor-corrected (PFC) DC voltage. Because the outlet voltages are PFC voltages, the amount of wasted power dissipated in the facility power lines/wiring and in the main power lines from the power company may be significantly reduced, without requiring each piece of equipment (e.g., an appliance, machinery) that is wired/plugged into the outlets to have an onboard PFC. This savings in wasted power may provide a significant cost savings to both the facility owner (e.g., lower electric bill) and the power company (e.g., lower power-generation and grid costs), and the ability to use equipment lacking onboard PFCs may reduce the purchase price of the equipment.

A detection and indication system for use in a railway switch machine which utilizes one or more roller members which physically interact with a point detector bar coupled to one or more switch points to provide an indication of a point failure upon movement of the point detector bar a predetermined distance from an initial position. The system includes a mounting structure structured to be coupled to a housing of the switch machine and a first sensing device coupled to the mounting structure. The first sensing device is positioned and structured to detect movement of the point detector bar a second predetermined distance from the initial position, wherein the second predetermined distance is less than the first predetermined distance.

A method of adjusting one or more of braking parameters used in a braking function to control braking of a train includes determining an adjustment factor based on a joint stopping distance probability distribution, the joint stopping distance probability distribution representing the composite effect on stopping distance of a plurality of predetermined train characteristic parameters, each of the predetermined train characteristic parameters being variable, and applying the adjustment factor to each of the one or more of braking parameters. Also, a method of adjusting braking parameters that includes determining an adjustment factor based on a nominal value, a worst case limit value and a best case limit value of each of a plurality of predetermined train characteristic parameters, each of the predetermined train characteristic parameters being variable, and applying the adjustment factor to each of the one or more of braking parameters.

A railroad monitoring apparatus includes first and second diverse vital processing units, first and second current sensors configured to measure the current being provided to one or more signaling elements of an item of wayside signaling equipment, and means for measuring voltage levels being supplied to each of the signaling elements. The first processing unit receives a first current measurement from the first current sensor and the measured voltage levels, and the second vital processing unit receives a second current measurement from the second current sensor and the measured voltage levels. The vital processing units are each programmed to determine based on one or more of the first current measurement, the second current measurement and the measured voltage levels: (i) the state of the item of railroad wayside signaling equipment, (ii) failures within the item of railroad wayside signaling equipment, and (iii) failures within the monitoring apparatus itself.

A sequential monitoring system is for an interlocking logic system and a track circuit system including a plurality of track circuits. The sequential monitoring system includes an interface between the interlocking logic system and the track circuit system; and a processor structured to monitor a state of each of the track circuits, validate a sequence of state changes of the track circuits, and interrupt and correct invalid track circuit state indications between the track circuit system and the interlocking logic system. The interface normally passes inputs from the track circuit system to outputs to the interlocking logic system. When an out of sequence event occurs, the processor applies a quarantine to a minimum of three of the track circuits in a quarantined area, thereby inhibiting use of an unoccupied track circuit in the quarantined area.
