Features in Version 3.1.0

  • SIOS PERC Dashboard™
    • Collapsible PERC Matrix
    • Issue Indicators at the Compute, Storage, and Network levels
  • PERC Issue List
    • The SIOS iQ PERC Issue List is designed to give the user insight into the status of their systems. It lists identified events and relevant event information such as severity, the start and end time of the event, the SIOS iQ determined root cause, the objects impacted by the event, as well as recommended actions regarding the event.

Features in Version 3.0.1

  • PERC
    • The SIOS PERC Dashboard™ provides a comprehensive view of your environment. It displays aggregated trends of Performance, Efficiency, Reliability, and Capacity across your compute, storage, and network layers.
  • Performance Root Cause
    • SIOS iQ presents any infrastructure component anomalies that may affect performance through the Performance Root Cause Analysis dashboard.The dashboard is split into two sections. The left section is a list of issues in chronological order that includes Severity, Start Time, End Time, and Issue Type information. The right section displays Details and Symptoms of the selected issue.
  • Storage Acceleration Analysis
    • Using Solid State Disks (SSDs) is a simple solution to performance issues caused by storage resource contention in the host machine. SSDs are used to offload storage and network traffic, improve storage performance, increase the density of the virtualization environment, and improve the application response time. The Storage Acceleration dashboard identifies the workloads that are best suited for storage acceleration, recommends the total cache and cache block size, and predicts the resulting performance benefits and cache-hit rate.
  • Efficiency – Idle VM Detection
    • The Efficiency dashboard identifies idle VMs in your infrastructure by continuously analyzing the environment, defining the normal conditions specific to that environment, and identifying idle VMs that may be deleted to free resources and save money. The analysis is continually updated without the need for manual intervention to set thresholds or run reports.
  • Efficiency – Snapshot Sprawl
    • The Efficiency dashboard lists the snapshots in the environment along with their age, size, number of siblings under the same VM, and potential cost savings that can be obtained if snapshots are deleted or collapsed.
