PernixData

PernixData is a software company that provides data acceleration and storage performance optimization software for virtualized data center environments.

• Software-defined data acceleration for virtualized workloads.
• Storage performance optimization integrated with hypervisor environments.
• Caching and I/O optimization for enterprise applications.
• Scale-out architecture for storage performance independent of capacity.
• Designed for deployment in virtualized data centers and private clouds.

More About PernixData

PernixData focuses on software-based platforms that improve storage performance in virtualized enterprise data centers. Its technology places a data acceleration layer close to the compute tier, typically at the hypervisor level, to improve I/O throughput and latency for virtual machines without requiring changes to underlying storage arrays. This approach targets organizations running large-scale virtualization estates that experience bottlenecks on shared storage systems.

The company’s offerings are positioned for environments built on enterprise hypervisors, where virtual machines share central storage resources such as SAN or Network Attached Storage (NAS). By intercepting and optimizing I/O operations at the host layer, PernixData seeks to increase effective performance for databases, transactional systems, and other I/O-intensive workloads. The software is deployed as part of the virtualization stack, where it can access local server resources such as flash or other high-speed media to cache frequently accessed data.

PernixData’s core architecture uses a distributed software-defined model in which each host contributes local resources to a pooled performance tier. This design enables storage performance scaling by adding or upgrading servers, rather than expanding the back-end storage array. The platform interacts with standard hypervisor constructs, such as virtual machines and datastores, and is designed to operate with common storage protocols like Internet Small Computer System Interface (iSCSI), Fibre Channel (FC), and NFS that are used in enterprise SAN and NAS systems.

From an enterprise IT categorization perspective, PernixData operates in the storage performance and caching layer for virtualized and private cloud environments (storage acceleration / data management). It is relevant for infrastructure teams seeking to address latency and throughput constraints without redesigning storage architectures. Compared with general-purpose storage arrays or all-flash systems, PernixData emphasizes a host-based software layer that can work with existing investments in shared storage.

In practice, PernixData’s technology is used by infrastructure and operations teams responsible for VMware and other virtualization platforms, capacity planners managing I/O-heavy workloads, and architects designing virtual infrastructures for predictable performance. The platform’s role in the stack is to provide a controllable, software-defined performance tier that can be applied across multiple applications, allowing organizations to tune or enhance storage performance policies at the virtualization layer rather than within each storage subsystem.
