Calsoft was engaged to maximize I/O performance from a Lustre file system for a large education provider. They created Lustre client and server packages for Ubuntu and CentOS, configured RAID6 storage from 60 SAS drives, and identified performance differences between the RAID6 drivers in the 2.6.32 and 3.16.3 Linux kernels. Calsoft proposed porting Lustre patches to the latest 3.16.3 kernel, including porting a zero copy patch and tuning performance from the SAS drives to RAID0, RAID6, and the Lustre server and client. This solution provided identical performance to proprietary hardware on commodity equipment.

Apache Cassandra performance advantages of the new Dell PowerEdge C6620 with ...Principled Technologies
The PowerEdge C6620 with PERC 12 delivered lower latency and higher throughput than an HPE ProLiant XL170r Gen9 server with an HPE Smart Array P440ar controller
Conclusion
Data proliferation today is rapid, and its growth shows no signs of stopping. For businesses that can take advantage of that data, there is tremendous potential value. One recent McKinsey study notes that “companies that are using data-driven B2B sales-growth engines report above-market growth and EBITDA increases in the range of 15 to 25 percent.” With data flooding in so quickly and in so many different forms, however, companies need high-performing big data solutions to have a chance at utilizing that data effectively.
We tested the performance of two platforms with a read-intensive Apache Cassandra database system bigdata workload to assess which might be better suited to speedily deliver the insights decision makers need. Compared to an older HPE ProLiant XL170r Gen9 server with an HPE Smart Array P440ar controller, the new Dell PowerEdge C6620 with Broadcom-based PERC 12 RAID controller delivered faster read and update latencies and more than twice the throughput. This improvement in performance can help you glean more value from your unstructured data more quickly. If you’re watching your stores of unstructured data grow but are still leaning on older servers for your critical Cassandra workloads, it may be time for an upgrade.Speeding time to insight: The Dell PowerEdge C6620 with Dell PERC 12 RAID con...
Speeding time to insight: The Dell PowerEdge C6620 with Dell PERC 12 RAID con...Principled Technologies
The new PowerEdge C6620 delivered better performance—both higher throughput and lower latency—than a previous-generation PowerEdge C6520 with PERC 11
Conclusion
The vast amounts of unstructured data that people and organizations generate daily have the potential to bring incredible value to companies that can utilize it quickly and correctly. Buried in the data are insights about consumer preferences, product performance, environmental trends, and more—but to access those insights at the speed of business, you need high-performing NoSQL databases. Aging servers may be holding you back from the full value of your data.
We found that the new Dell PowerEdge C6620 with Broadcom-based PERC 12 RAID controller can speed read-intensive Apache Cassandra database workloads compared to an older server solution. Faster read and update latencies and higher throughput, as we saw the PowerEdge C6620 deliver, can speed the retrieval, processing, and analysis of your unstructured data, enabling you to more effectively extract its value. To more fully utilize your data to inform your everyday business operations, consider the Dell PowerEdge C6620 with Broadcom-based PERC 12 RAID controller.More Related Content

The PowerEdge R750 solution boosted performance compared to a previous-generation PowerEdge R740 with PERC 10
Conclusion
Companies increasingly turn to big data applications to solve business problems such as understanding customer habits and behavior, maintaining electronic health records, and detecting fraud. In a 2022 survey of executives, 97.0 percent had invested in big data initiatives, and 73.7 percent said their organizations had appointed a Chief Data Officer (CDO), up from 12 percent in 2012.
With so much data at play, storage becomes an essential consideration for companies as they select hardware platforms to run their vital workloads. Two primary requirements for storage are fast performance and redundancy. Companies seek storage that can quickly put actionable insights into the hands of decision makers. At the same time, it is a fact of life that storage media occasionally fails, and no company wants to risk the potentially very large expense of losing vital business data.
In our testing with a disk-intensive TeraSort big data workload, we found that a current-generation Dell PowerEdge R750 server with a Broadcom-based Dell PERC 11 RAID controller with NVMe SSDs outperformed a previous-generation PowerEdge R740 server with a Dell PERC 10 RAID controller. The newer PowerEdge R750 solution completed the workload in 13.9 percent less time and with 16.3 percent better throughput, indicating that it could speed the delivery of insights to decision makers. With its PERC 11 RAID controller, it also offers RAID support for today’s speedy NVMe SSDs. Data-driven organizations must weigh the cost savings of putting off purchases of newer servers against the benefits of investing in those same newer, more powerful servers with RAID support for NVMe drives. Our testing shows that with the Dell PowerEdge R750 server with a Broadcom technology-based Dell PERC 11 RAID controller, buyers need not choose between redundancy and high performance.Scalability: Lenovo ThinkServer RD540 system and Lenovo ThinkServer SA120 sto...

Private clouds require an investment in hardware that can often be costly—a cost that grows along with the size of distributed database workloads a business deploys. The new AMD EPYC processor architecture can help ease that burden by increasing the available number of cores per socket, which could let businesses get more distributed database work done per server compared to a previous generation Intel Xeon E5-2699 v4 processor architecture. In our tests, we found that a cluster based on 32-core AMD EPYC 7601 processors increased the operations per second an Apache Cassandra distributed database could process by 50 percent over a same-sized cluster based on 22-core Intel Xeon processors E5-2699 v4.3 This means that businesses seeking to run these reliable, elastic databases on a private cloud setup could do so on an AMD EPYC 7601 processor-based server platform and experience faster updates and shorter data load times.Boosting performance with the Dell Acceleration Appliance for Databases

We deployed this modern environment, then migrated database VMs from legacy servers and saw performance improvements that support consolidation
Conclusion
If your organization’s transactional databases are running on gear that is several years old, you have much to gain by upgrading to modern servers with new processors and networking components and an OpenShift environment. In our testing, a modern OpenShift environment with a cluster of three Dell PowerEdge R7615 servers with 4th Generation AMD EPYC processors and high-speed 100Gb Broadcom NICs outperformed a legacy environment with MySQL VMs running on a cluster of three Dell PowerEdge R7515 servers with 3rd Generation AMD EPYC processors and 25Gb Broadcom NICs. We also easily migrated a VM from the legacy environment to the modern environment, with only a few steps required to set up and less than ten minutes of hands-on time. The performance advantage of the modern servers would allow a company to reduce the number of servers necessary to perform a given amount of database work, thus lowering operational expenditures such as power and cooling and IT staff time for maintenance. The high-speed 100Gb Broadcom NICs in this solution also give companies better network performance and networking capacity to grow as they embrace emerging technologies such as AI that put great demands on networks.Dell Acceleration Appliance for Databases 2.0 and Microsoft SQL Server 2014: ...

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
