What Cleversafe Inc. Is and How Its Data Storage Technology Works
Cleversafe Inc. developed a unique object storage technology that breaks data into pieces, encodes it with redundancy, and distributes it across many servers or locations. This design improves durability and security while supporting large-scale storage needs. Understanding Cleversafe’s dispersed storage approach helps IT professionals evaluate if it fits their organization's need for scalable, resilient, and secure data storage.
What is Cleversafe Inc. and why does it matter?
Cleversafe Inc. set out to change how digital data is stored and protected by introducing a method that splits data into fragments and spreads those fragments across multiple servers or geographic sites. This means the system can tolerate hardware failures, data corruption, or site outages without losing information. Cleversafe addressed the challenge of storing massive data volumes reliably and cost-effectively, which is vital for organizations managing growing digital assets.
How does Cleversafe’s object storage technology work?
Cleversafe uses a dispersed storage architecture where data is divided into multiple slices. Each slice is encoded with redundancy using erasure coding, which allows the system to rebuild the original data even if some slices are missing. These slices are distributed across a network of storage nodes, so retrieving data requires accessing only a subset of the slices.
Each data slice is encrypted individually. This means no single node contains enough information to reconstruct the data, enhancing security and reducing the risk of breaches. The combination of dispersal, erasure coding, and encryption provides strong resilience against hardware failures, data corruption, and disasters impacting data centers.
What makes Cleversafe different from traditional storage solutions?
Traditional storage systems like SAN or NAS store data in large, contiguous blocks on specific devices and protect data mainly through replication—keeping multiple full copies. This approach increases storage overhead and creates potential single points of failure if replicas are unavailable.
Cleversafe’s technology avoids full replication by using erasure coding to create smaller, redundant data slices. This reduces the extra storage needed to protect data. Its dispersed architecture spreads data slices across many nodes and locations, eliminating single points of failure. This design also supports easier scalability and fault tolerance than traditional centralized or limited-distributed storage systems.
Who uses Cleversafe technology and for what?
Cleversafe technology suits organizations requiring large-scale, durable, and secure data storage. Media and entertainment companies use it to manage vast video libraries that need reliable long-term preservation and access. Healthcare providers rely on it to securely archive patient records and medical images while meeting regulatory compliance.
Cloud providers integrate Cleversafe’s object storage to offer scalable back-end storage services. Financial institutions apply it for secure archiving of transaction records and compliance data. In general, any organization with big data sets, long-term archival demands, or high availability and security requirements can benefit from Cleversafe’s approach.
What happened to Cleversafe after its acquisition?
IBM acquired Cleversafe in 2015 and integrated its dispersed object storage technology into IBM’s storage portfolio. This allowed IBM to offer scalable, durable, and secure object storage within its cloud and hybrid cloud products. Existing Cleversafe users gained access to IBM’s development resources and support, as well as integration with IBM’s data management and analytics tools.
Today, Cleversafe’s technology continues within IBM’s Cloud Object Storage offerings, providing enterprises with resilient and secure cloud-based storage solutions based on Cleversafe’s original principles.
What are common myths or misunderstandings about Cleversafe?
A frequent misconception is that Cleversafe stores multiple full copies of data across servers. In fact, it uses erasure coding, which is more storage-efficient than full replication.
Another misunderstanding is that Cleversafe is only suitable for cold or archival storage. While it excels in those areas, it can also support active workloads depending on deployment.
Some believe that data dispersal causes poor performance. However, Cleversafe uses optimized retrieval methods that deliver performance suitable for many enterprise applications.
Finally, some think Cleversafe is a standalone product no longer supported after IBM’s acquisition. Actually, IBM has integrated the technology into its offerings, providing ongoing support and modernization within its storage ecosystem.
Conclusion
If your organization needs a storage solution with strong durability, security, and scalability, Cleversafe’s dispersed object storage technology is worth considering. IBM’s current cloud object storage products build on Cleversafe’s approach, making these capabilities accessible for modern data management challenges.
Frequently Asked Questions
Is Cleversafe technology suitable for real-time data access?
Cleversafe was designed for durability and security but can support real-time data access depending on configuration and workload. It’s commonly used for both archival and active data storage.
Does Cleversafe require special hardware?
Cleversafe runs on commodity hardware, spreading data slices across standard servers, which helps reduce costs compared to specialized storage devices.
How does Cleversafe ensure data security?
Data slices are encrypted before distribution so no single storage node has enough information to reconstruct the original data, providing strong security.
