Stratus Technologies, an SGH company, announced the release of Stratus Redundant Linux (SRL) 3.0, the latest version of its Linux-based operating system for the Stratus ztC Edge platform, and everRun 8.0, the newest iteration of the company’s continuous availability software, which provides fault-tolerant performance across heterogeneous x86-based compute infrastructure.
Stratus continues its commitment to Linux development using the Ubuntu distribution to deliver its combination of built-in fault tolerance and virtualization in an open environment. SRL 3.0 and everRun 8.0 helps to simplify edge manageability, improve security, and increase performance up to 30 percent over previous versions, helping users to run multiple mission-critical applications with a solution designed to help eliminate downtime and data loss.
Simplified Edge Manageability and Up to 30% Performance Increase with Stratus Redundant Linux 3.0
Stratus Redundant Linux is its ztC Edge’s operating system (OS) that is designed to provide both built-in virtualization and out-of-the-box high availability and fault tolerance. Using ztC Edge, organizations are able to deploy edge computing infrastructure to run mission-critical applications with a solution designed to help eliminate downtime and data loss outside the enterprise, such as at branch locations or rugged industrial sites where IT staffs are typically limited.
Stratus ztC Edge is purpose-built for OT and IT teams to help to more rapidly modernize and scale edge infrastructure for more efficient, flexible, and future-proofed operations. SRL 3.0 is backwards compatible with the ztC Edge 100i, 110i, 200i, and 250i platforms.
New features and enhancements that SRL 3.0 brings to the ztC Edge platform include:
New APIs for expanded edge manageability – SRL 3.0 adds more than two dozen RESTful API calls for remote management and visibility into platform health from local control rooms, the cloud, or single-pane-of-glass operations centers. These APIs help to simplify the management of Stratus ztC Edge platforms and enable end users to manage those platforms alongside other devices using their preferred IT tools.
Up to 30% increase in performance – The latest version of SRL delivers additional processing efficiency, typically resulting in a boost in performance over ztC Edge platforms running previous versions of SRL.
Support for more Linux guest operating systems – SRL 3.0 expands the list of guest OSs it supports, including the most recent Linux variants such as CentOS Stream, Oracle Enterprise Linux, Red Hat Enterprise Linux, and Ubuntu Server. For the full list of Windows and Linux guest OSs that SRL 3.0 supports, visit the Stratus ztC Edge guest operating system support page.
Non-redundant virtual machines for cybersecurity use cases – End users have the option to designate select virtual machines (VMs) as non-redundant in a paired/dual deployment ztC Edge configuration. This capability helps to enable IT teams to prevent the spread of malware by setting up a single, non-redundant VM for threat scanning and one-way traffic monitoring.
Shift to Ubuntu Linux-based development – With SRL 3.0, Stratus has moved from its prior CentOS-based Linux development to Ubuntu Linux, which is one of the largest and most popular versions of Linux. This change helps to ensure a long-term roadmap for Linux development as well as regular support for common vulnerabilities and exposures (CVEs) and other patches.
Expanded Fault-Tolerant Performance for New and Existing x86 Infrastructure with everRun 8.0
Stratus’ everRun software helps to bring fault tolerance to a heterogeneous IT infrastructure in an open, standards-based Linux environment, which helps to ensure that applications continue to run without interruption or data loss. It also helps to enable organizations to leverage the features and functionality of SRL 3.0 and its Linux-based fault tolerance and virtualization to new and existing Intel x86 server infrastructure. In addition, everRun 8.0 adds support for Intel’s fourth-generation Xeon Scalable line of server processors.
As a perpetual license, everRun 8.0 is available for download and upgrade at no charge for customers on Stratus Support contracts.
Craig Resnick, ARC Advisory Group, commented “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. Being able to do so in open environments that simplify management and reduce IT dependencies is paramount to creating more agile and resilient business.”
