Stratus Enhances Edge Capabilities with Greater Manageability, Performance, and More

Stratus Technologies Inc., an SGH company and a global leader in simplified, protected, and autonomous computing platforms for the edge and the data center, is debuting two innovations: Stratus Redundant Linux (SRL) 3.0, the latest update to the company’s Linux-based operating system for the Stratus ztC Edge platform, and everRun 8.0, a new iteration of Stratus’ continuous availability software. These latest releases continue to solidify Stratus’ commitment to Linux development while forwarding easy edge manageability, robust security, and enhanced performance, according to the company.

“The latest release by Stratus of its continuous availability software with built-in virtualization is key for us to continue running a Linux environment while also gaining higher performance and security, enabling multiple virtual machine modes and allowing users to have more capabilities in different scenarios,” said Wei Zhang, industrial computing product manager, Shanghai Hi-Tech Control System Co., Ltd. “Additionally, the open RESTful API interface can be integrated with more IT and OT systems to facilitate monitoring and maintenance by OT field personnel. Stratus’ everRun software will be used in more industries to help customers improve business continuity and save more costs.”

As ztC Edge’s operating system (OS), SRL 3.0 is the heart of ztC Edge’s built-in virtualization and out-of-the-box high availability and fault tolerance, according to the company. SRL 3.0 is purpose-built for OT and IT teams tasked with quickly modernizing and scaling edge infrastructure, empowering them to do so without downtime or data loss outside of the enterprise.

The introduction of SRL 3.0 brings with it a variety of new features and enhancements, including:

  • New RESTful APIs for expanded edge manageability, offering greater visibility into platform health from local control rooms, the cloud, or single-pane-of-glass operation centers.
  • Up to 30% increase in performance via greater processing efficiency.
  • Support for more Linux guest operating systems, including CentOS Stream, Oracle Enterprise Linux, Red Hat Enterprise Linux, and Ubuntu Server.
  • Non-redundant virtual machines for cybersecurity use cases which prevent the spread of malware.
  • Greater focus on Ubuntu Linux-based development, ensuring a long-term roadmap for Linux development and regular support.

everRun 8.0—the solution that brings fault tolerance to heterogeneous IT infrastructure in an open, standards-based Linux environment—empowers enterprises to utilize the benefits of SRL 3.0 within new and existing Intel x86 infrastructures. The update also offers support for Intel’s fourth-generation Xeon Scalable line of server processors.

“Organizations face the dual challenge of rapidly modernizing their edge infrastructure and ensuring maximum reliability of their underlying compute infrastructure to innovate with software and harness edge data for insight,” said Craig Resnick, vice president of consulting, ARC Advisory Group. “Being able to do so in open environments that simplify management and reduce IT dependencies is paramount to creating more agile and resilient business.”
