Alternative to SAN – Why Software-Defined Storage Wins in the Long Run

SAN systems have been dominant in the enterprise storage market for over two decades. The landscape of enterprise storage is changing. Enterprises are no longer just evaluating storage solutions based on upfront costs—because traditional SAN vendors now offer competitively priced hardware, and there are plenty of financing options to avoid significant CAPEX investments. 

Instead, the actual financial and operational burden comes from Day 2 operations, long-term lifecycle management, and other overhead, including the extra staffing cost to manage these complex systems. This is where Software-Defined Storage (SDS) solutions like simplyblock truly shine and offer significant flexibility, scalability, and operational efficiency advantages.

Understanding Day 2 Operations and Lifecycle Management

Day 2 operations refer to the ongoing tasks and processes that occur after the initial deployment of a storage solution. These include:

• Maintenance and Upgrades: Regular updates to hardware and software components to ensure optimal performance and security.
• Scalability Adjustments: Expanding or reducing storage capacity in response to changing organizational needs.
• Performance Optimization: Continuous tuning to meet evolving workload demands.
• Data Migration: Moving data between storage systems or locations without disrupting operations.
• Monitoring and Troubleshooting: Proactive identification and resolution of issues to minimize downtime.

Effective lifecycle management encompasses the entire span of a storage solution’s existence—from planning and deployment to decommissioning—ensuring that the system remains efficient, cost-effective, and aligned with business objectives throughout its life.

While the initial purchase price of traditional storage solutions may appear competitive, several hidden costs can accumulate over time.

Why It’s No Longer About Upfront Costs

Many storage buyers assume that choosing a SAN storage system means paying a premium for enterprise-grade hardware and software. However, SAN vendors have become more aggressive in pricing their hardware to compete with new entrants in recent years. The problem? The hidden costs of SAN storage emerge after deployment, including:

• Proprietary Hardware Dependencies: Traditional storage solutions rely on proprietary hardware, leading to vendor lock-in and limited flexibility. This dependency can result in higher costs for hardware replacements or upgrades and may restrict the ability to adopt newer, more cost-effective technologies.
• Expensive Software Licensing: Additional features like data replication, tiering, and deduplication often require costly licenses. Access to all enterprise features typically means lots of additional costs on the licensing side, which drastically change initially attractive-looking calculations. While paying for great software is fair, SAN vendors’ software stack works only with their hardware.
• High Maintenance Contracts: SAN support and maintenance costs tend to increase significantly over time, and it’s hard to foresee these costs upfront. The more problems you have with the system, the higher the support costs become, which doesn’t feel like a fair deal for many users.
• Costly Hardware Refresh Cycles: Upgrading and expanding SAN systems often involves buying new hardware stacks. Even when hardware replacement programs are included in the pricing, this still leads to significant operational disruption and personnel overhead from time to time, as the entire system needs to be replaced.
• Operational Complexity: Managing and optimizing SAN environments requires specialized knowledge, leading to higher admin costs. Is it really a good thing that a vendor needs to offer certifications just so you can manage their system? In 2025, IT operations should be as simple and as automated as possible. Human involvement should be minimal — but that’s still not the case with most SANs.

Thus, the real reason IT leaders are seeking a SAN alternative isn’t the initial purchase price — it’s the long-term inefficiencies and operational expenses that follow.

Day 2 Operations: Where Traditional SAN Falls Short of Software-Defined Storage

Once a traditional SAN is deployed, enterprises often experience the challenges of Day 2 operations. This is where software-defined storage (SDS) solutions like simplyblock stand out. SDS is all about scalability, easy hardware upgrades, and simple maintenance. Once the system is set up and online, it can and should stay online forever, regardless of disk, server, or network failures. This is the promise of software-defined storage above all — it’s not just about being able to work with commodity hardware. Let’s look at the advantages of simplyblock over legacy SAN systems in more detail.

1. Complexity in Scaling

Traditional SAN architectures often require buying larger controllers or replacing entire systems when scaling. This rigid scaling model leads to expensive forklift upgrades. These systems also have physical scalability limits beyond which they can’t grow.

🔹 Simplyblock as a SAN Replacement: Simplyblock offers a true scale-out architecture that lets organizations expand storage seamlessly by adding new nodes — without downtime, bottlenecks, or costly hardware overhauls. Simplyblock’s architecture is designed for theoretically unlimited scalability.

2. Software Licensing and Feature Restrictions

With traditional SAN systems, enterprise features such as high-availability configurations, advanced tiering, and cloud integration often require expensive software add-ons.

🔹 Simplyblock as a SAN Alternative: Simplyblock provides enterprise-grade features out of the box with no hidden licensing fees. Capabilities like erasure coding, storage tiering,

3. High Ongoing Maintenance Costs

Traditional SAN storage solutions require costly support contracts for firmware updates, bug fixes, and hardware replacements. Organizations are often locked into multi-year contracts just to keep their systems running efficiently.

🔹 Simplyblock as a SAN Replacement: With Simplyblock’s Software-Defined Storage (SDS) approach, enterprises can choose their preferred hardware, avoid vendor lock-in, and dramatically reduce maintenance costs.

4. Time-Consuming Lifecycle Management

Traditional SAN systems often require frequent manual intervention for upgrades, data migrations, and capacity management, leading to increased administrative overhead.

🔹 Simplyblock as a SAN Alternative: Simplyblock’s automated management system simplifies lifecycle operations, allowing IT teams to monitor the infrastructure and react in case of hardware failures or when capacity thresholds are reached. These tasks do not require special skills or vendor-specific certifications.

5. Lack of Ability to Accurately Estimate TCO 

With SAN systems, since there is usually a significant upfront cost involved, one might consider it an “investment” for the future. Nothing is more misleading. That is just the beginning of spending. Additional license costs for new or advanced features, excessive support requirements, or overprovisioning typically lead to higher consolidated spending after the purchase than during the purchase.

🔹 Simplyblock as a SAN Alternative: With simplyblock, pricing is fully transparent. Not only can you calculate your storage TCO upfront, but you can also get an actual enterprise license where, for a limited period, you won’t have any additional costs. This might finally feel like a real investment, not a never-ending expense.

6. Dependence on Proprietary Hardware : 

SAN vendors often advertise that their hardware is better than commodity (OEM) gear. However, in reality, they rely on third-party suppliers, as most of the key components of their systems are sourced externally. These vendors do not manufacture SSDs themselves. Rebranding the hardware makes it seem significantly different or better than standard off-the-shelf components. While their R&D efforts and hardware-specific optimizations are real, the actual benefits are marginal—especially when you factor in the risk of vendor lock-in that this model introduces.

🔹By decoupling storage software from hardware, simplyblock allows organizations to utilize commodity hardware, eliminating vendor lock-in and enabling more cost-effective hardware choices. This flexibility simplifies hardware upgrades and replacements, reducing costs and extending the lifecycle of the storage infrastructure. Additionally, the modern OEM hardware is so performant and reliable that there is no need for unique optimization. At least for the vast majority of organizations. If you’re Meta, Tesla, or OpenAI, you might need the cutting edge provided by a single component in your stack. However, if you are not, you are probably already underutilizing your storage and compute resources.
