Configuration Settings

A – Fast!UTIL

Extended Control Block. This setting enables all other extended firmware settings. The default is Enabled.

RIO Operation Mode. This setting specifies the reduced interrupt operation (RIO) modes, if supported by the software driver. RIO modes allow posting multiple command completions in a single interrupt (see table A-4). The default is 0.

Option

Operation Mode

 

 

0

No multiple responses

1

Multiple responses, 16 bit handles, interrupt host

2

Multiple responses, 32 bit handles, interrupt host

3

Multiple responses, 16 bit handles, delay host interrupt

4

Multiple responses, 32 bit handles, delay host interrupt

 

 

Connection Options. This setting defines the type of connection (loop or point to point) or connection preference (see table A-5). The default is 3.

Table A-5. Connection Options

Option

Type of Connection

0Loop only

1Point to point only

2Loop preferred, otherwise point to point

3Point to point, otherwise loop

Class 2 Service. This setting enables Class 2 service parameters to be provided during all automatic logins (loop ports). The default is Disabled.

ACK0. This setting determines the type of acknowledge (ACK) used. When this setting is enabled, sequence ACK is used. When this setting is disabled, frame ACK is used. The default is Disabled.

NOTE: The Class 2 Service setting must be enabled to use the ACK0 setting.

Fibre Channel Tape Support. This setting is reserved for Fibre Channel tape support, which will be implemented in a future version of the QLA22xx. The default is Disabled.

Fibre Channel Confirm. This setting is reserved for Fibre Channel tape support, which will be implemented in a future version of the QLA22xx. The default is Disabled.

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.
