IBM announces end of Dell storage driver support for IBM i Systems: What it means for you

In a recent announcement that may have gone unnoticed by many, IBM revealed that Dell has elected not to renew a long-standing licensing agreement that enabled the D910 device driver for IBM i systems. This driver allowed IBM i users to connect Dell PowerMax storage without needing specially formatted block disks or relying on IBM VIOS (Virtual I/O Server).

With the decision effective for new Dell PowerMax purchases after November 1, 2024, existing customers may find themselves reevaluating storage options and connectivity solutions for IBM i environments.

Let’s break down what this change entails and what options IBM i users should consider moving forward.

The D910 Interface: What It Does and Why It Matters

The D910 interface has been an essential piece of technology for IBM i and Dell PowerMax users. Originally developed through a collaboration between EMC and IBM, the D910 driver provides a native IBM i interface that supports high-performance drives like Flash, Fibre Channel, SAS, and SATA in a straightforward manner. This setup enables the use of standard format drives, eliminating the need for specialised 520-byte per block formatting.

By providing native IBM i device-type support, the D910 driver helps customers utilise Dell PowerMax storage directly with IBM i systems running version 6.1.1 and above. In essence, this driver simplified storage management for IBM i users, creating a seamless connection without added complexity.

Who Will Be Affected?

The announcement affects IBM i users who connect to Dell storage directly through the D910 interface. Those who connect via VIOS or the vSCSI interface remain unaffected. For IBM i systems on versions V7R4 and V7R5, Dell support will continue until 2029, giving current users a few years of uninterrupted functionality. However, the driver will no longer receive updates or enhancements for future IBM i releases beyond V7R5. This could impact customers running critical Power10 systems and planning to stay on IBM’s latest operating systems.

Planning for IBM i Upgrades Beyond V7R5

With this announcement, it’s essential for IBM i users relying on Dell PowerMax storage to start considering the implications. Although there’s no immediate urgency for current systems, future compatibility and support may become increasingly challenging, particularly as IBM pivots responsibility to Dell for ongoing driver support. Now is an opportune moment to explore alternative storage solutions that align with IBM i’s evolving landscape.

Exploring Your Storage Options

1. Transition to VIOS:
For some users, connecting Dell storage via IBM i using VIOS might be an option, though it requires reconfiguration and allocating additional resources to support VIOS. However, this isn’t ideal for all due to potential complexities and resource overhead.

2. Internal Flash Storage for IBM i:
Depending on your storage needs, internal flash storage could be a simple, cost-effective solution. This approach keeps all storage management within IBM i, offering a streamlined support process by avoiding the need for external connections.

3. Switch to IBM FlashStorage Solutions:
Replacing Dell PowerMax with an IBM FlashStorage SAN might be another viable choice. While this may require some configuration adjustments, it brings advanced features like immutable snapshots and FlashCore module technology that older Dell systems lack.

4. Virtualise the Dell Storage:
If your organisation needs to retain Dell storage due to recent investments or multi-platform compatibility, you could virtualise it behind an IBM FlashSystem controller. IBM’s SVC technology can integrate multiple vendors’ storage systems, allowing for enhanced performance and management under a single interface.

What’s Next?

While the announcement doesn’t necessitate an immediate overhaul, it’s a clear sign for IBM i users to start planning their storage strategy. Examining options that align with IBM i’s future OS releases and support structure can prevent potential disruptions down the line.

Frequently Asked Questions

Here are answers to common questions IBM and Dell users may have:

Q: How long will PowerMax support IBM i?

A: PowerMax models will support IBM i through their respective End of Standard Support dates (e.g., October 31, 2029, for PowerMax 2000/8000) for existing users.

Q: Is there any change in Dell PowerMax support in an IBM i environment? 

A: No. Current Dell support remains the same, and any issues with the D910 interface introduced by IBM updates are unlikely based on historical data.

Q: If an IBM PTF disrupts the D910 driver, will Dell support it?

A: Yes. Dell will work with IBM to address any issues caused by IBM updates, as part of a collaborative support framework.

Q: Who can get a no-charge key for IBM i 7.6?

A: Existing customers with Dell storage connected before November 1, 2024, will be eligible to obtain a key from IBM.
