5 – Red Hat Linux Driver Installation Installing the Driver

5.3.2.2

Building a Symmetric Multiprocessor (SMP) Version of the Driver

Perform the following steps to build an SMP version of the qla4000 driver:

1.Extract the kernel-header and kernel-source RPM files from the first Red Hat CD-ROM.

#cd /mnt/cdrom/RedHat/RPMS

#rpm -ivkernel-headers*.rpm(not required for Red Hat Linux 7.3)

#rpm -iv kernel-source*.rpm

2.Prepare source headers for an SMP module build by changing to the Linux source directory. Type the following:

#cd /usr/src/linux-2.4

3.Type the following command to access the Main Menu:

#make menuconfig

a.From the Main Menu, select Processor type and features and press

ENTER.

b.From the Processor Type and Features menu, select Symmetric multiprocessor and press the SPACEBAR.

c.Select Exit to exit the Processor Type and Features menu.

d.Select SCSI Support and press ENTER.

e.Select SCSI Generic Support and press the SPACEBAR twice.

f.Select Exit to exit the SCSI Support menu.

g.Select Exit to exit the Main Menu.

The system prompts Do you wish to save your new kernel configuration? Select Yes. The system saves a new config file .config in the current directory.

4.Under the kernel source directory, type the following:

#make dep

5.Create a new directory, /qla4xxx. Using the driver disk created in section 5.2, copy the qla4xxxsrc-v1.xx.tgz file to /qla4xxx and extract the files. For example:

#mkdir qla4xxx

#cd /qla4xxx

#mcopy a:*.tgz . (The period (.) at the end is required.)

#tar -xvzf *.tgz

6.Build the qla4000 driver from the source code by typing:

#make

NOTE: Refer to Makefile for additional supported command line parameters.

4000 SERIES specifications

The Q-Logic 4000 Series represents a significant advancement in storage networking solutions, particularly designed to meet the high demands of modern data centers. As businesses continue to accumulate vast amounts of data, the need for efficient, high-performance storage solutions becomes more pronounced. This series shines in delivering flexibility, scalability, and high availability.

One of the standout features of the Q-Logic 4000 Series is its support for advanced protocols such as Fibre Channel and Ethernet. This versatile capability enables seamless integration within diverse environments, whether organizations are operating on traditional storage area networks (SANs) or transitioning to more cost-effective, high-speed Ethernet-based storage solutions. The flexibility in protocol support allows businesses to tailor their infrastructure to their specific needs without being tied to a single technology.

The Q-Logic 4000 Series also boasts a robust performance, featuring high IOPS (Input/Output Operations Per Second) capabilities that cater to I/O-intensive applications and large-scale virtualized environments. This efficiency is crucial for workloads such as database management, big data analytics, and mission-critical applications. Additionally, the series employs advanced technologies such as hardware offload and flow control mechanisms, resulting in reduced CPU usage and improved overall system performance.

High availability is another critical characteristic of the Q-Logic 4000 Series. The products are engineered with redundancy and failover mechanisms that ensure continuous operation, thereby reducing downtime and bolstering business continuity. Built-in features such as link aggregation and adaptive load balancing further enhance reliability and performance, allowing organizations to maintain optimal operations even amidst traffic fluctuations.

Scalability is a central theme in the design of the Q-Logic 4000 Series. The architecture supports linear scaling, enabling users to grow their networking capabilities in alignment with their expanding data needs. This characteristic is particularly beneficial for companies anticipating growth, as it allows them to invest in the system incrementally.

Security features within the Q-Logic 4000 Series also receive significant attention. The implementation of encryption technologies and secure access protocols ensures that sensitive data remains protected from unauthorized access and cyber threats.

In summary, the Q-Logic 4000 Series positions itself as a cutting-edge solution in the storage networking landscape, combining advanced technologies, high performance, and robust security features. Whether for a growing enterprise or an established data center, these products deliver a compelling solution for modern storage challenges.
