Configuration Settings

A – Fast!UTIL

■Execution Throttle. This setting specifies the maximum number of commands executing on any one port. When a port’s execution throttle is reached, no new commands are executed until the current command finishes executing. The valid options for this setting are 1-256. The default (optimum) is 16.

■Fast Command Posting. This setting decreases command execution time by minimizing the number of interrupts. The default is Enabled.

■>4GByte Addressing. This option should be enabled if the system has more than 4 Gbytes of memory available. The default is Disabled.

■LUNs per Target. This setting specifies the number of LUNs per target. Multiple LUN support is typically for redundant array of independent disks (RAID) boxes that use LUNs to map drives. The default is 8. If you do not need multiple LUN support, set the number of LUNs to 0.

■Enable LIP Reset. This setting determines the type of loop initialization process (LIP) reset that is used when the operating system initiates a bus reset routine. When this setting is yes, the driver initiates a global LIP reset to clear the target device reservations. When this setting is no, the driver initiates a global LIP reset with full login. The default is No.

■Enable LIP Full Login. This setting instructs the ISP chip to re-login to all ports after any LIP. The default is Yes.

■Enable Target Reset. This setting enables the drivers to issue a Target Reset command to all devices on the loop when a SCSI Bus Reset command is issued. The default is No.

■Login Retry Count. This setting specifies the number of times the software tries to log in to a device. The default is 8 retries.

■Port Down Retry Count. This setting specifies the number of times the software retries a command to a port returning port down status. The default is 8 retries.

■Drivers Load RISC Code. When this setting is enabled, the host adapter uses the RISC firmware that is embedded in the software driver. When this setting is disabled, the software driver loads the RISC firmware that is stored in the QLA22xx BIOS. The default is Enabled.

NOTE: The driver being loaded must support this setting. If the driver does not support this setting, the result is the same as disabled regardless of the setting. Leaving this option enabled guaranties a certified combination of software driver and RISC firmware.

■Enable Database Updates. When enabled, this setting allows the software to save the loop configuration information in flash memory when the system powers down. The default is No.

QLA22XX specifications

The Q-Logic QLA22XX series encompasses a range of high-performance Fibre Channel Host Bus Adapters (HBAs) designed to enhance data storage and network connectivity within enterprise environments. Specifically, these adapters are tailored for environments requiring robust storage solutions, ensuring that organizations can effectively manage their data traffic and optimize their storage strategies.

At the heart of the QLA22XX is its adherence to the Fibre Channel standard, which allows for high-speed connections between servers and storage devices. These adapters support speeds of up to 16 Gbps, which provides the bandwidth necessary for handling multiple workloads simultaneously. This capability is crucial for businesses that rely on rapid access to large volumes of data, thereby facilitating quicker decision-making processes and enhancing productivity.

The QLA22XX series features advanced technologies such as enhanced error correction and adaptive routing. These technologies ensure data integrity and reliability during transfer, reducing the likelihood of data corruption. Additionally, the adaptiveness of the routing capabilities allows the HBA to optimize performance by dynamically adjusting to various network conditions and topologies.

Another key characteristic of the QLA22XX is its compatibility with a multitude of operating systems, including major platforms like Windows, Linux, and VMware. This broad compatibility simplifies deployment across diverse IT ecosystems, making it easier for organizations to integrate these HBAs without extensive modifications to their existing infrastructure.

Moreover, the QLA22XX series supports the latest management and monitoring tools, enabling administrators to have complete visibility into performance metrics and potential issues. This includes support for the SNMP protocol, which facilitates proactive monitoring and management of the networked storage systems.

Energy efficiency is also a consideration in the design of the QLA22XX series. These adapters are engineered to minimize power consumption, which not only aids in reducing operational costs but also contributes to the organization's sustainability goals.

In summary, the Q-Logic QLA22XX series is a reliable and high-performance Fibre Channel HBA solution. With its high-speed connectivity, advanced technologies for data integrity, broad compatibility, and proactive management features, it stands out as a robust option for enterprises looking to enhance their data storage and network connectivity capabilities.
