The 3592s can be placed inside of the 3584 or 3494 tape libraries or you can mount them in a separate rack. Please discuss the required library features with your local IBM sales team or business partner.

The required software for 3592 attachment is already installed in the DR550. This includes updated device drivers and a new version of Tivoli Storage Manager (5.2.3). You will need to make sure that the firmware on the 3592 is updated to the latest version if you are using existing machines. If you have purchased new 3592s, the firmware for WORM support will already be installed.

Data Migration

When using tape with the DR550 SMB, you should review the appropriate Tivoli Storage Manager parameters involved with data migration. TSM has the ability to migrate data from one media to another (from the disk in the DR550 SMB to a WORM cartridge in the 3592 as an example) as determined by the parameters. These parameters are documented in the TSM publications and are also included in the DR550 redbook. Two of the parameters that should be reviewed include:

MIGDelay

Specifies the minimum number of days that a file must remain in a storage pool before the file becomes eligible for migration from the storage pool. The server counts the number of days from the day that the file was stored in the storage pool or retrieved by a client, whichever is more recent. This parameter is optional. You can specify an integer from 0 to 9999. The default is 0, which means that you do not want to delay migration.

If you want the server to count the number of days based only on when a file was stored and not when it was retrieved, use the NORETRIEVEDATE server option.

MIGContinue

Specifies whether you all the server to migrate files that do not satisfy the migration delay time. This parameter is optional. The default is YES>

Because you can require that the files remain in the storage pool for a minimum number of days, the server may migrate all eligible files to the next storage pool yet not meet the low migration threshold. This parameter allows you to specify whether the server is allowed to continue the migration process by migrating files that do not satisfy the migration delay time.

Possible values are:

Yes

Specifies that, when necessary to meet the low migration threshold, the server continues to migrate files that do not satisfy the migration delay time.

If you allow more than one migration process for the storage pool, some files that do not satisfy the migration delay time may be migrated unnecessarily. As one process migrates files that satisfy the migration delay time, a second process could begin migrating files that do not satisfy the migration delay time to meet the low migration threshold. The first process that is still migrating files that satisfy the migration delay time might have, by itself, cause the low migration threshold to be met.

No

DR550 SMB V.1 specifications

The IBM DR550 SMB V.1 is a robust data protection solution designed to meet the needs of small and medium-sized businesses (SMBs). This innovative platform combines advanced technologies with user-friendly features, making it an ideal choice for organizations looking to secure their data without overwhelming complexity or significant financial investments.

One of the main features of the IBM DR550 SMB V.1 is its integrated data deduplication capability. This technology significantly reduces the amount of storage space required for backups by eliminating redundant copies of data. As a result, businesses can store more information efficiently, leading to cost savings and more effective use of resources.

The platform also supports multi-tiered storage options, enabling users to easily manage data across various storage environments. This flexibility is crucial for SMBs that may have limited storage capabilities but still require scalable solutions to accommodate growth. The ability to migrate data seamlessly between different tiers enhances operational efficiency and ensures that businesses can handle their evolving data needs without frequent disruptions.

Another noteworthy characteristic of the DR550 SMB V.1 is its cloud integration support. The ability to back up data to the cloud provides additional protection and redundancy, allowing organizations to ensure data availability even in the event of hardware failures or disasters. This feature is especially important for SMBs operating with limited IT resources, as it simplifies disaster recovery processes and enhances overall business continuity.

The user interface of the IBM DR550 SMB V.1 is designed with accessibility in mind. Its intuitive dashboard allows users to monitor backup statuses easily, configure schedules, and manage recovery options without extensive technical expertise. This user-friendly approach reduces the learning curve for employees and empowers businesses to take control of their data protection strategies.

In terms of security, the DR550 SMB V.1 employs advanced encryption technologies to safeguard sensitive information both during transit and at rest. This focus on data security is vital for meeting compliance requirements and maintaining customer trust in an increasingly data-driven world.

Overall, the IBM DR550 SMB V.1 stands out as a comprehensive solution that merges advanced backup technology with essential features tailored for small and medium-sized businesses. Its combination of data deduplication, multi-tier storage support, cloud integration, and robust security measures makes it a valuable asset for organizations looking to enhance their data protection capabilities while ensuring ease of use and scalability.
