RAID Implementation and Configuration in Operating Systems

2025-09-19

Some programs are written directly on the host computer, running at the bottom level of the operating system. Using the concept of the Big Dipper, they virtualize the physical disks presented by the host's SCSI or IDE controller into various virtual disks, which are then presented to upper-level programming interfaces such as volume management programs. These software programs use a configuration tool to allow users to select which disks to combine and what type of RAID configuration to form.

 

For example, a machine might have two IDE drives and four SCSI drives installed. The IDE drives are connected directly to the motherboard's integrated IDE interface, while the SCSI drives are connected to a PCI SCSI card. Without the involvement of a RAID program, the system can recognize all six drives, format them with the file system, and mount them to a drive letter or directory for read/write access by applications.

 

After installing the RAID program, the user uses the configuration interface to configure the two E drives into a RAID 0 system. If each IDE drive originally had a capacity of 80GB, the RAID 0 configuration would create a single "virtual" disk with a capacity of 160GB. The user then configured a RAID 5 system with four SCSI drives. If each SCSI drive originally had a capacity of 73GB, the virtual disk capacity after the four drives were configured in RAID 5 would be approximately the capacity of three drives, or 216GB.

Of course, because the RAID program uses some of the disk space to store RAID information, the actual capacity will be reduced. After processing by the RAID program, these six drives are ultimately reduced to two virtual disks. In Windows, opening Disk Manager will only show two hard drives: one with a capacity of 160GB (hard drive 1) and the other with a capacity of 219GB (hard drive 2). These two drives can then be formatted, for example, using the NTFS file system. The formatting program will be completely unaware of the data being written to multiple physical drives.

 

For example, at a certain moment, the formatting program issues a command to write data from memory start address X to LBA start address 10000 and length 128 on hard drive 1 (a RAID 0 virtual drive composed of two IDE drives). The RAID program intercepts this command and analyzes it. If hard drive 1 is a RAID 0 system, the RAID engine will calculate the data for the 128 sectors starting at LBA 10000, mapping the logical LBAs to the physical LBAs of the physical disks and writing the corresponding data to the physical disks. After writing, the formatter receives a successful write signal and proceeds to the next I0. This process obscures the upper-level program's knowledge of the underlying physical disk details. Other RAID configurations operate in the same way, albeit with more complex algorithms. Even these complex algorithms, when processed by the CPU, are thousands or even tens of thousands of times faster than disk read and write speeds.

Snow Removal Robots Enter North American Households The Key Role of Crystal Oscillators in Efficiency Gains

2025-09-19

In recent years, the North American market has witnessed a surge in the adoption of snow removal robots. Statistics show that around 70% of single-family homes in the U.S. are located in snow-prone regions, where traditional manual snow removal takes more than 50 hours annually. With the rise of intelligent devices, snow removal robots have evolved from “luxury gadgets” into essential household tools during winter, offering over tenfold efficiency gains compared to manual labor.

Crystal Oscillators for Snow Removal Robots

Behind this rapid adoption are breakthroughs in key technologies: precise navigation, reliable wireless communication, and stable performance in low-temperature environments. At the heart of these innovations, crystal oscillators—often described as the “heartbeat” of electronic systems—play a critical role in ensuring the reliable and efficient operation of snow removal robots.

 

Crystal oscillators provide accurate clock signals for navigation and positioning systems, enabling robots to efficiently plan routes across driveways and yards while avoiding missed or redundant clearing. In addition, for remote control and cloud connectivity, crystal oscillators ensure the stability of Wi-Fi, Bluetooth, and other wireless modules, preventing delays or disruptions caused by frequency drift. More importantly, in extreme sub-zero conditions, automotive-grade and temperature-compensated crystal oscillators (TCXOs) maintain exceptional stability, ensuring consistent performance even in harsh weather.

 

As a company with nearly 30 years of expertise in frequency components, JGHC Crystals has introduced a range of TCXOs and differential oscillators. With advantages in high stability, low-temperature resilience, and low power consumption, these products have become ideal solutions for intelligent snow removal equipment. Industry experts note that as the snow removal robot market continues to expand in North America, the demand for crystal oscillators will only grow further.

VM600 System Grounding Instructions(2)

2025-08-21

The VM600 turbine monitoring system for a million-unit nuclear power plant primarily measures and monitors relative shaft vibration, absolute bearing seat vibration, axial displacement of the turbine rotor relative to the thrust bearing, and rotor elongation relative to the turbine cylinder reference point.

Let's discuss the VM system.

1. Hardware
Vibro-Meter's VM600 series machine protection and monitoring system is based on a 19" x 6U frame and includes various components depending on the application. There are basically two types of systems:

Machine Protection System (MPS)

Condition Monitoring System (CMS)

MPS and CMS hardware can be integrated into the same frame.

The following details the hardware included in the MPS (see Figure 1).

1) The ABE 04 X frame structure (19" x 6U) comes in two types: ABE040 and ABE042. The difference lies in the mounting position of the brackets within the frame. 2) RPS 6U rack power supply unit
3) MPC 4 rack protection card
4) IOC 4T MPC 4 input/output card
5) AMC 8 analog monitoring card

6) IOC 8T AMC 8 input/output card

VM600


Figure 1 Configuration Diagram

The MPC 4 and IOC 4T cards must be used in pairs; no card can be used individually. These cards are primarily used for vibration monitoring. Similarly, the AMC 8 and IOC 8 T cards must be used in pairs; these cards are primarily used for quasi-static parameters such as temperature, level, or flow.

A rack can contain:

Only one pair of MPC 4 / IOC 4 T cards

Only one pair of AMC 8 / IOC 8 T cards

A combination of one pair of MPC 4 / IOC 4 T and one pair of AMC 8 / IOC 8 T cards

Depending on the application, the following card types can also be installed in the rack:

7) RLC 16 Relay Card (16 relays) All of the above modules can be used to form a standalone MPS system, that is, a system not connected to a network. A networked MPS system, in addition to the above hardware, also includes the following hardware for the ABE 04 X frame:
8) CPUM CPU card
9) IOCN input/output card (matching the CPU M). Depending on the application requirements (regardless of whether the frame is a stand-alone or networked configuration), one or more of the following low-noise power supply components may be used outside the frame:
APF195 DC-DC converter
APF196 AC-DC converter
Any customer-supplied equivalent low-noise power supply unit
These devices must be used with GSI 1 XX galvanic isolation units, GSV safety barriers, and converters/proximitors with currents greater than 25 mA.

2. Software
One of the following software packages is required to configure the MPS:
1) MPS 1 Configuration Software
This software configures the MPC 4 and AMC 8 cards in the networked VM600 frame, which includes a CPU for control and communication. All cards in the frame can be configured in "oneshot" mode via Ethernet.


2) MPS 2 Configuration Software
This is an expanded version of the MPS 1 software package. In addition to providing all the functionality of MPS 1, MPS 2 software also includes MPC 4 and AMC 8 management, unit diagrams, and data trending.

3. MPS Communication Methods
The MPS system can be configured in a variety of ways, depending on the hardware installed in the ABE04X rack.

1) Figure 2-a below shows the simplest MPS configuration. This is a stand-alone rack. In this case, the MPC 4 or AMC 8 card in the rack must be configured using a personal computer via RS-232 communication, which is connected through the 9-pin connector on the front of the card.


2) Figure 2-b shows a rack containing a CPU card (CPU M). The Ethernet connection between the personal computer and the MPS system is established through the front panel of the CPU M card. Communication between the CPU M and the MPC 4/IOC 4 T or AMC 8/IOC 8 T card is via the VME bus on the rack backplane.

3) Figure 2-c shows a rack containing a CPU card (CPU M) and matching IOC N input/output cards. Ethernet connections are established between the personal computer and the MPS system via the IOC N card's backplane. Communication between the CPU M and the MPC 4/IOC 4 T or AMC8/IOC 8 T cards occurs via the VME bus on the rack's backplane.

4. MPS Monitored Parameters
The MPC 4 card in the MPS system can measure the following parameters:
Absolute vibration (shoe vibration)
Relative vibration (radial vibration measurement, including DC gap voltage measurement)
Absolute rotor vibration and rotor position (axial measurement)
Smax vector value (compliant with ISO 7919 standard)
Rotor eccentricity
Absolute and relative expansion (between rotor and stator)
Cylinder expansion
Displacement
Dynamic pressure
The AMC 8 card in the MPS system can measure the following parameters:
Temperature (thermocouples or RTD probes connected directly to the IOC 8 T card)
Any user-defined process variable, such as flow, level, or valve position. Other MPS system features include:
Hot-swappable MPC 4, IOC 4 T, AMC 8, IOC 8 T, and RLC16 cards. These cards can be inserted or removed without powering down the ABE04X frame.
Single-board configuration storage
Online modification of all parameters while the MPS is running
Real-time data processing available
Configurable internal power supply for transmitters
Built-in self-test (BITE) circuit
Hazardous bypass function
Alarm signal reset
Alarm multiplication or adaptive monitoring
Up to four inputs (measured vibration, dynamic pressure, etc.) can be connected to a single processing channel.
