Introduction

Carlson Companies, a prominent privately held enterprise with diverse business interests including hospitality, travel, and restaurants, faced significant challenges in managing its rapidly growing data environment. To support its operational needs and strategic goals, the company transitioned from dispersed storage methods to a centralized Storage Area Network (SAN) based on Internet Protocol (IP) technology. This paper analyzes how Carlson’s storage solutions meet its IT goals, compares centralized and distributed data storage approaches, and reviews observed benefits in other organizations that have adopted the Shared Storage Model (SSM) from the Storage Networking Industry Association (SNIA).

1. Addressing Carlson’s IT Goals with Storage Solutions

Carlson’s IT division established a set of six strategic objectives to support its expansion and operational efficiency, namely implementing an enterprise data warehouse, building a global network, moving to an enterprise-wide architecture, achieving Six Sigma quality standards, facilitating outsourcing and data exchange, and leveraging existing technologies. The deployment of a SAN provided a cohesive framework that directly supports these goals.

The core of the new storage infrastructure—the IP-based SAN—enables scalable, reliable, and cost-efficient data management. Its utilization of Gigabit Ethernet switches and Nishan IP storage switches allows seamless integration of servers and storage systems across local and wide areas, thus underpinning Carlson’s objective to build a global network and support enterprise-wide architecture. The SAN’s scalability permits the addition of storage arrays and servers without disrupting ongoing operations, facilitating continuous growth aligned with Carlson’s data expansion, which exceeds ten terabytes of critical data.

Furthermore, centralized storage simplifies management and backup processes. The SAN's architecture ensures robust disaster recovery capabilities similar to the existing mainframe plan, which was essential for maintaining high availability of mission-critical applications. The ability to perform remote backups over IP networks supports Carlson’s goal of facilitating outsourced services and data exchange with remote sites, a vital aspect of its global operations.

2. Centralized versus Distributed Data Storage: Pros and Cons

The previous distributed storage approach, where each server maintained separate disk storage, offered responsiveness with minimal access times but incurred high management and backup costs. It also lacked a unified disaster recovery strategy for the servers outside the mainframe environment. The dispersed storage system posed significant challenges in data reconciliation, increased administrative burden, and heightened risks of data inconsistency. As data volume grew, managing multiple storage environments became inefficient and costly.

In contrast, Carlson’s centralized SAN consolidates storage resources into a single, scalable system, yielding several advantages:

  • Cost-effectiveness: The IP-based Ethernet switches used in the SAN are less expensive and easier to manage than traditional Fibre Channel switches.
  • Simplified Data Management: Centralized control streamlines data backup, recovery, and administration, reducing operational overhead.
  • Enhanced Data Security and Disaster Recovery: Centralization allows for more consistent security policies and robust disaster recovery plans, as exemplified by the mainframe’s existing backup procedures.
  • Scalability and Flexibility: Adding new storage or servers is straightforward, supporting future growth without major reengineering.

However, the centralized approach also introduces some challenges:

  • Potential Bottlenecks: Large data flows can cause network congestion if not properly managed.
  • Single Point of Failure: Centralized systems need high redundancy and fault tolerance measures to prevent outages.
  • Initial Implementation Complexity: Transitioning from dispersed storage requires careful planning to ensure data migration during production hours, as done successfully at Carlson.

Overall, the consolidation of storage into a centralized SAN aligns with Carlson’s strategic objectives by providing scalable, manageable, and secure data infrastructure suited for a global enterprise.

3. Observed Benefits of the Shared Storage Model in Other Organizations

Organizations adopting the SNIA’s Shared Storage Model (SSM) report several benefits similar to those realized by Carlson. The SSM, which delineates storage architectures into layered components and interfaces, facilitates optimized resource utilization and simplified management. Industry case studies reveal consistent advantages including:

  • Cost Savings: Centralized storage reduces hardware and administrative expenses. For instance, a large telecommunications provider experienced a 30% reduction in storage costs post-implementation of SSM-aligned solutions (Higgins, 2002).
  • Improved Data Accessibility: Shared storage environments enhance data sharing across departments, regions, and organizations, leading to better collaboration and business agility.
  • Higher Reliability and Availability: Organizations report increased uptime, thanks to redundancy and strategic backup implementations within shared storage frameworks (Kranz, 2004).
  • Enhanced Disaster Recovery: Centralized, shared storage facilitates robust backup and recovery strategies, vital for minimizing downtime and data loss during incidents (SearchStorageChannel, 2012).
  • Operational Efficiency: A unified architecture reduces complexity, enabling IT staff to streamline operations, monitor performance easier, and implement uniform security policies (Clark, 2002).

These benefits underpin the broader strategic advantages—cost efficiency, operational resilience, and agility—that are vital for modern organizations aiming to sustain competitive advantage in data-intensive environments.

Conclusion

Carlson Companies’ strategic shift to an IP-based SAN exemplifies how centralized storage solutions effectively meet enterprise IT goals such as scalability, reliability, and cost reduction. The comparative analysis highlights significant advantages over dispersed storage, notably in management simplicity and disaster recovery. Observed benefits in other organizations adopting shared storage architectures reinforce the value of the SNIA’s Shared Storage Model, emphasizing cost efficiency, operational resilience, and streamlined data sharing. As data volumes continue to escalate, intelligent and scalable storage architectures like Carlson’s SAN will remain crucial to supporting organizational growth and operational excellence.
