Computational storage is a data storage technology for optimally arranging both data analytics and data management functions within a storage device.

The Storage Networking Industry Association (SNIA) defines it as an architecture that provides computational functions in storage as a way of offloading host processing or reducing data movement. This enables improvements in application performance and infrastructure efficiency through the integration of compute resources that would normally be provided via traditional compute and memory resources.

The computational element is either directly situated within storage or can be placed between the host and the storage. The ultimate goal is to enable parallel computation and alleviate constraints on existing compute, memory, storage, and I/O.

This approach bypasses the need to move data between the CPU and a storage layer, a reason for slow response times. By hosting high-performance computing applications within the storage itself, it is possible to lower resource consumption, reduce costs, and achieve higher throughput. It also removes any bottleneck between data paths and host CPUs by moving computational elements into or beside the storage device.

Computational Storage Use Cases

There are multiple use cases for computational storage:

  • Solid state devices (SSDs): SSD idiosyncrasies include writes being slower than reads, random writes being particularly slow, and writes wearing out devices over time. Computational storage can materially improve applications that use SSD storage by helping to avoid random writes and economizing on the use of writes in general. This includes relational and noSQL databases, analytics, software defined storage, and metadata associated with HDD based storage.
  • Hyperscale data centers execute a great variety of parallel workloads: Adding more intelligent and higher powered storage can helps reduce Capex, Opex, power and cooling demands, and lower the physical footprint.
  • Edge: Intelligent storage solutions provide low power, more efficient compute where it is needed. Telecom providers, for example, can use computational storage to support a massive amount of data processing at the edge.
  • IoT: Automotive and aerospace providers, in particular, are among the leaders in deploying computational storage to make sense of vast amounts of sensor data
  • Content Data Networks (CDNs): Computational storage improves key management, encryption, and access controlled content by moving computation closer to consumers.

How to Select a Computational Storage Vendor 

What are the most important criteria a user should look at when evaluating computational storage options?

Align with Precise Needs

The value of a specific computational storage solution depends on how closely it aligns to the solution of a variety of challenges related to data size, the movement of large data sets, and the location of that data. If implemented correctly, it can provide the needed support to turn raw data sets into more meaningful results or simplify the work needed to be done by the CPU, GPU, or other processing engines.

Determine the Relative Importance of Performance, Efficiency, and Resilience

Different approaches to computational storage may address one or more of these areas better than others. For example, storage-related functions of SSD-based applications consume resources from the CPU, SSD, and network. Computational storage can directly address performance and throughput and reduce latency.

Evaluating Cost

As always there is a tradeoff between cost and functionality. Some computational storage platforms may offer more power, but it may not be needed for some applications. Balance cost against value to the enterprise.

Value Proposition:

The Pliops Storage Processor (PSP) is a hardware-enabled storage engine available as a cloud service or in a PCIe card form factor. With Pliops storage acceleration, companies can consolidate existing infrastructure, eliminate bottlenecks, and improve resource utilization without changing applications. The computational resources in the Pliops Storage Processor can be used to deploy data structures and algorithms that optimize the disparate costs of compute and storage. Pliops claims that customers have measured performance throughput gains as high as 25x and latency improvements greater than 1,000x.
