Setting vca Driver Parameters

You can set the vca device driver parameters in two ways:

Using the ndd utility

Using the vca.conf file

If you use the ndd utility, the parameters are valid only until you reboot the system. This method is good for testing parameter settings.

To set parameters so they remain in effect after you reboot the system, create a /kernel/drv/vca.conf file and add parameter values to this file when you need to set a particular parameter for a device in the system. See “To Set Driver Parameters Using a vca.conf File” on page 38 for details.

Setting Parameters Using the ndd Utility

Use the ndd utility to configure parameters that are valid until you reboot the system.

The following sections describe how you can use the vca driver and the ndd utility to modify (with the -setoption) or display (without the -setoption) the parameters for each vca device.

To Specify Device Instances for the ndd Utility

Before you use the ndd utility to get or set a parameter for a vca device, you must specify the device instance for the utility.

1.Check the /etc/path_to_inst file to identify the instance number associated with a particular device. Refer to the online manual pages for path_to_inst(4).

#grep vca /etc/path_to_inst "/pci@8,600000/network@1" 0 "vca" "/pci@8,700000/network@1" 1 "vca"

In the previous example, the three Sun Crypto Accelerator 4000 Ethernet instances are from the installed adapters. The instance numbers are 0 and 1.

2.Use the instance number to select the device.

#ndd -set /dev/vcaN

4000 specifications

Sun Microsystems, a pivotal player in the computing industry during the late 20th and early 21st centuries, was renowned for its innovative hardware and software solutions. Among its notable offerings were the Sun-6000, Sun-5000, and Sun-4000 series, powerful workstations and servers designed for a range of enterprise-level applications.

The Sun-6000 series, introduced in the early 1990s, marked a significant advancement in computing performance. These systems were built on the SPARC architecture, which facilitated high levels of processing power and multitasking capabilities. One of the main features of the 6000 series was its scalability, allowing organizations to increase their processing power by adding more modules. It also offered robust graphics performance, making it ideal for scientific visualization and complex data analysis.

Next in line was the Sun-5000 series. Launched shortly after the 6000 series, the 5000 line was celebrated for its reliability and ease of management. This series emphasized a balanced architecture, which combined processing capabilities with ample memory and storage options. Key characteristics included support for multiple processors, leading to improved performance for demanding applications. Additionally, the 5000 systems featured advanced input/output capabilities, ensuring fast data transfers—crucial for database applications and web servers.

Finally, the Sun-4000 series targeted businesses seeking affordable yet potent computing solutions. These servers boasted a modular design, allowing for easy upgrades and maintenance. The 4000 series was particularly notable for its support for various operating systems, including SunOS and Solaris. These systems were engineered to handle a range of workloads, from enterprise resource planning to web hosting, while still fitting into a value-driven budget.

Across all three series, Sun Microsystems prioritized compatibility and integration, ensuring that each system offered seamless connectivity with Sun's software solutions and third-party applications. Their commitment to open standards and interoperability set them apart in the competitive landscape of enterprise computing. Additionally, the use of high-quality components lent the systems durability, making them a wise investment for organizations looking to future-proof their IT infrastructure.

In summary, the Sun-6000, 5000, and 4000 series exemplified Sun Microsystems' ethos of innovation and reliability. These powerful systems catered to diverse business needs, setting benchmarks in performance and functionality that continue to influence modern computing.
