Changing the iSCSI Target Identification

You cannot change the iSCSI target name, but you can associate an alias with the target for simpler identification. Aliases are useful because the iSCSI target names are not intuitive. You should provide an iSCSI target alias that is meaningful and easy to remember.

1Click the iSCSI tab, and then click Change Target Identification.

2Type the alias in the iSCSI target alias field and click OK.

NOTE: Aliases can contain a maximum of 30 characters. Aliases can include letters, numbers, and the special characters underscore (_), minus (-), and pound sign (#). No other special characters are permitted.

NOTE: Open iSCSI (which is used by Red Hat Enterprise Linux 5 and SUSE® Linux Enterprise Server 10 with SP 1) does not support using target alias.

Changing the iSCSI Target Discovery

1Click the iSCSI tab, and then click Change Target Discovery.

2Select the Use iSNS server check box to activate iSCSI target discovery. You can use one of these methods:

a Use the DHCP option (IPv4 only) to automatically activate target discovery. You also can refresh the DHCP.

b Type the IPv4 or IPv6 address to activate the target discovery. After you manually enter an IP address, you also can click Advanced to set the customized TCP listening ports.

3If you do not want to allow discovery sessions that are not named, select

Disallow un-named discovery sessions.

Un-named discovery sessions are discovery sessions that are permitted to run without a target name. With an un-named discovery session, the target name or the target portal group tag is not available to enforce the iSCSI session identifier (ISID) rule. For more information on un-named discovery sessions, click the Support tab, then click View Online Help.

Computer Drive specifications

Dell Computer drives are a crucial component of the brand's range of products, delivering reliable storage solutions tailored for various user needs. Dell offers a diverse lineup of drives, including solid-state drives (SSDs), hard disk drives (HDDs), and hybrid drives, each featuring distinct characteristics that cater to different performance requirements.

One standout feature of Dell's SSDs is their use of advanced NAND flash technology. This results in significantly faster read and write speeds compared to traditional HDDs, ensuring quicker boot times and application loading. With capacities ranging from 128GB to 8TB, Dell SSDs are ideal for both casual users and professionals who require consistent performance for data-intensive applications such as video editing, gaming, and large database management.

Dell's HDDs, on the other hand, remain a popular choice for users who prioritize storage capacity over speed. With options available in sizes from 500GB to 10TB, these drives offer users ample space to store large files, such as videos, music libraries, and software applications. Dell's enterprise-grade HDDs are known for their durability and reliability, making them suitable for server environments where data integrity is paramount.

Incorporating hybrid drives, Dell brings the best of both worlds. By combining the speed of SSDs with the capacity of HDDs, hybrid drives offer a balanced solution for users seeking improved performance without sacrificing storage space. These drives utilize a small amount of SSD storage as a cache to speed up frequently accessed files, enhancing overall system responsiveness.

Dell also emphasizes data protection in its drive offerings, with features like encryption and secure erase capabilities. This focus on security is vital for users in business environments, where sensitive information must be safeguarded against unauthorized access.

Another characteristic that sets Dell drives apart is their compatibility with a wide range of systems. Dell ensures that its drives can seamlessly integrate with various models, from laptops to desktops and servers. Furthermore, Dell's support for RAID (Redundant Array of Independent Disks) configurations allows users to configure their storage systems for enhanced performance, redundancy, or both.

In conclusion, Dell Computer drives encompass a comprehensive range of features and technologies that meet the needs of diverse users. With their emphasis on speed, capacity, durability, and security, Dell drives are a trusted choice for anyone seeking reliable storage solutions. Whether in personal computing or enterprise environments, Dell stands at the forefront of storage technology, continually evolving to meet user demands.
