Interrupt Parameters

TABLE 3-7describes the receive interrupt blanking values.

TABLE 3-7RX Blanking Register for Alias Read

Field Name	Values	Description

rx-intr-pkts	0 to 511	Interrupts after this number of packets have arrived
		since the last packet was serviced. A value of zero
		indicates no packet blanking. (Default=3)
rx-intr-time	0 to 524287	Interrupts after 4.5 microseconds (usecs) have elapsed
		since the last packet was serviced. A value of zero
		indicates no time blanking. (Default=3)

Random Early Drop Parameters

These parameters provide the ability to drop packets based on the fullness of the receive FIFO. By default, this feature is disabled. When FIFO occupancy reaches a specific range, packets are dropped according to the preset probability. The probability should increase when the FIFO level increases. Control packets are never dropped and are not counted in the statistics.

TABLE 3-8RX Random Early Detecting 8-Bit Vectors

Field Name	Values	Description

red-dv4to6k	0 to 255	Random early detection and packet drop vectors for
		when FIFO threshold is greater than 4096 bytes and less
		than 6,144 bytes. Probability of drop can be
		programmed on a 12.5 percent granularity. For
		example, if bit 0 is set, the first packet out of every
		eight will be dropped in this region. (Default=0)

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.
