VIAVI Releases Monitoring and Analysis System for Serial Attached SCSI Storage Network Testing

VIAVI Solutions announced availability of the Xgig 1000 24 Gbps SAS Analyzer, a solution for validating and ensuring 24G Serial Attached SCSI (SAS) network performance in a fully integrated, stand-alone system.

This versatile storage network testing solution helps equipment manufacturers improve R&D efforts, as well as supporting data center deployment and troubleshooting in the field.

VIAVI’s Xgig 1000 24 Gbps Analyzer enables simultaneous analysis and error injection for SAS protocol traffic at all layers of the stack, delivering one of the most powerful monitoring and analysis systems available for SAS applications. The system not only captures and analyzes live data traffic to verify performance, it also provides traffic jammer capabilities to simulate errors in real time for testing the responsiveness of error recovery processes.

The latest SAS 4.0 protocol standard introduces significant technological changes in response to demands for increased storage capacities and faster data speeds, supporting a number of important optimizations for solid-state drives. This new industry standard doubles the effective bandwidth previously possible, from 12 to 24 Gbps. Network equipment manufacturers need optimized testing capabilities to ensure their next-generation 24 Gbps storage systems do not become a bottleneck.

“The ability to test network storage equipment and identify how and when a system fails is key to developing the most robust, high-performance solutions possible for data-intensive applications, ranging from unified communications and large internet content providers to gaming platforms,” said Tom Fawcett, VP and GM, Lab and Production Business Unit, VIAVI Solutions. “We have refined the Xgig 1000 24 Gbps Analyzer to address the specific characteristics of the SAS 4.0 protocol at high speeds so that every data bit is passed through exactly as it was received, and allowing users to see the same signal that the device under test sees.”

While other test and troubleshooting systems can involve complicated, repetitive processes, the Xgig 1000 24 Gbps Analyzer offers users the option to define automation scripts, from simple commands to complex regression test libraries. Analyzer and jammer functions can be managed easily by toggling software switches in the Maestro user interface.

The Xgig 1000 24 Gbps SAS Analyzer blade chassis supports 24/12/6/3 Gbps SAS with dual mini-SAS HD receptacles, allowing bidirectional analysis of single and wide-port SAS links. A design with front-to-back airflow allows for standing the chassis on end, minimizing the overall footprint in desktop testing.

Enterprises today operate in a real-time environment where uninterrupted access to trusted data has become a baseline expectation for users, applications and automated systems. Traditional DataOps models, built on manual effort and human triage, cannot keep pace with this always active demand. AI agents are emerging as the operational backbone, ensuring consistent data availability, reinforcing trustworthiness and enabling a level of scale that manual processes cannot achieve ...

For decades, trust in the digital workplace rested on familiar signals. We trusted faces on video calls, voices on the phone, and emails that appeared to come from people we knew. These cues felt human and intuitive. They anchored how decisions were made, approvals were granted, and access was authorized. AI-powered deepfakes have quietly broken that model ...

Cloud migration was supposed to be a one-way door. For most enterprises, it turns out it isn't. Cloud data repatriation is a real and growing trend. A new survey ... finds that 89% of organizations plan to expand their on-premises infrastructure footprint over the next two years — and 75% have already moved at least some workloads back from public cloud in the past 24 months. The findings point to a broad rethinking of where data belongs ...

Over the past few years, large language models (LLMs) have revolutionized the software industry. Given their ability to excel at multi-step reasoning, LLMs have helped enterprises streamline workflows and adapt to the unknown. However, employing such models comes with sky-high costs, latency issues, and limited flexibility. In the realm of IT operations, it is generally wiser to employ smaller, domain-specific models instead ...

For years, DevOps teams operated under a simple assumption: collect enough telemetry, and you can find and fix any problem. That assumption is breaking down.
