PA-Storage is a simple, cost-effective storage performance monitoring solution for your critical Microsoft® and Linux® applications and virtualization infrastructure.  It works in conjunction with Linux SNMP, Microsoft PowerShell and VMware® PowerCLI to agentlessly monitor storage performance of logical and physical disks, as well as NFS (VMware) and CIFS/SMB (Windows) from the “Server Side”, the only side that matters to your applications.   In virtualization environments, performance monitoring is available inside the virtual machine as well as at the hypervisor level, providing valuable insight into where any bottlenecks reside.  PA-Storage’s rich set of features (see screen shots below) have you understanding and improving your storage and application performance in short order.  The expert analytics provide visibility to application performance deficits that were not previously detectable.  As such, creating a powerful tool to help decipher the cause/effect of changes to your data and storage infrastructure, and the impact on your application performance.


Typical use cases:

  • Service-Level Agreement management for private-cloud, on-premise 3rd-party managed cloud, and cloud service providers with unique “TALC” performance tracking
  • Storage I/O performance troubleshooting including real-time updates (5 second sampling) of critical servers
  • “Server Side” benchmarking for new storage technologies, including separate read and write key performance indicators
  • Provider-independent and architecture-independent cloud Storage I/O performance management
  • Transfer-size aware latency detection and alerting for establishing accurate baselines and enforcing Service-Level Agreements
  • Logical disk free space percentage alerting to head-off application disruptions
  • CPU utilization tracking to understand relationships between storage performance issues and CPU utilization

PA-Storage Screen Shots

Main Screen, with Standard-Charts (see above): Green/Yellow/Red dashboard view linked to Transfer-Size Aware latency rules; all the key performance indicators in one place including latency, transfer size, IOPS, MB/s, queue length, CPU, logical disk free space, and more. And watch it all in real-time on critical servers.

Custom Chart: Graph anything, with anything else.  Over months, weeks, days, hours, minutes…or even seconds with 5-second sampling.  This chart also updates in real-time.


Custom Chart Configuration: See what’s important to you….


Analytics (sub-set of data shown): Get all the gory detail.  All the data is automatically compiled, even updated in real-time if you are up for it.  Profor’s PA-Storage analytics are a result of years of experience solving tricky application and storage performance problems.  The data is distilled into useful information about how well the storage is performing, including a full break down of performance for samples that are within, as well as outside of, the transfer-size aware latency rules.


Top Talkers (client data obscured below): This data is sorted, by default, descending based on Total I/Os.  The chart, which extends considerably further to the right, can be sorted on any of the columns, allowing you to look at any KPI, sorted by storage object or server.


Got TALC? The Transfer-Size Aware Latency Compliance chart (“TALC” for short) is the single-most effective storage-performance metric in the industry.  Intended for managing directors and storage engineers alike, TALC lets you know what percentage of your I/O is operating within you transfer-size-aware service levels.  As always with PA-Storage, the metric is derived from the most important perspective: the “Server Side”.  TALC is perfect for managing your SLA’s, but it is also very well suited for benchmarking, bake-offs, and knowing with confidence when a storage issue is really resolved: “Did the TALC return to pre-issue levels?”


Alert-Setup: Easily setup your Transfer-Size Aware SLA’s as well as your logic drive free-space alerts.
