When managing a Dell EqualLogic SAN (Storage Area Network) solution, particularly when it is actively in production, adhering to Dell’s hardware maintenance guidelines is critical. Staying within maintenance contracts not only ensures that your equipment is covered in case of hardware failure but also allows you access to firmware updates and replacements for components such as drives.
Maintenance and Hardware Support
Production Environment: If your EqualLogic SAN is in a production environment, maintaining an active support contract with Dell is crucial. This enables timely updates of drive firmware and access to replacement parts. Dell’s ability to supply new drive units can be contingent on this ongoing maintenance relationship, and without it, replacement components might be challenging to source. It is advisable to keep an inventory of critical components if you opt out of a maintenance contract, but this should be a last resort.
Non-Production Environment: For test or lab environments, flexibility increases. You can utilize third-party drives in the SAN, but be aware that this can lead to compatibility issues. The EqualLogic firmware might not recognize or leverage the full functionality of non-certified drives. This option remains feasible primarily for non-critical environments where the risk of reduced functionality or data resilience is acceptable.
Firmware Considerations and Functionality
One of the significant advantages of using Dell-certified drives comes from the functionality of the EqualLogic firmware. This software includes features that enhance system resilience, such as the ability to automatically snapshot and transfer data from a failing drive to a healthy one. This proactive failure management reduces recovery time and potential data loss. Opting for non-certified drives can compromise these features, as the firmware is specifically designed and tested with Dell-certified components.
Best Practices
- Maintain Active Support: Ensure all production SANs are under active maintenance contracts with Dell for optimal support and update access.
- Inventory Management: If choosing to operate without a maintenance contract, maintain a stockpile of critical components to mitigate the risk of downtime.
- Compatibility Testing: For non-production environments using third-party drives, test extensively to ensure compatibility with your EqualLogic firmware and anticipate any limitations or issues with regard to data redundancy features.
