Storage Metrics
Storage metrics (or data storage metrics) are measurements and indicators used to assess various aspects of a storage system’s performance, capacity, and efficiency. These metrics provide valuable insights into how data storage resources are utilized, helping organizations optimize their storage infrastructure, plan for future needs, and troubleshoot issues.

Common data storage metrics
Capacity Utilization:
- Used Capacity: The amount of storage space currently in use.
- Free Capacity: The remaining storage space available for use.
Throughput:
- IOPS (Input/Output Operations Per Second): The number of read and write operations that a storage system can perform in one second.
- Throughput: The amount of data (in bytes) transferred per unit of time.
Latency:
- Read Latency: The time it takes for a storage system to respond to a read request.
- Write Latency: The time it takes for a storage system to acknowledge the completion of a write operation.
Availability:
- Uptime/Downtime: The percentage of time the storage system is available versus the time it is unavailable.
Reliability: - Error Rate: The frequency of errors or data corruption within the storage system.
Data Protection:
- Backup Success/Failure: The success or failure rate of backup operations.
- Snapshot Usage: The utilization of snapshot technology for data protection.
Storage Efficiency:
- Deduplication Ratio: The ratio of data reduction achieved through deduplication.
- Compression Ratio: The ratio of data reduction achieved through compression.
Data Lifecycle Management:
- Data Age: The age of data in the storage system, helping in the management of data lifecycle.
Resource Utilization:
- CPU and Memory Usage: The utilization of CPU and memory resources on storage devices.
Network Performance:
- Bandwidth: The amount of data that can be transmitted over the network in a given time.
Queue Length:
- Storage Queue Length: The number of I/O operations waiting to be processed by the storage system.
Monitoring these storage metrics provides data storage administrators and IT teams with the information needed to make informed decisions about storage provisioning, performance optimization, and overall system health. Many storage management tools and platforms offer dashboards and reports that display these metrics for easy analysis and troubleshooting.
Unified Data and Storage Insights
Komprise Storage Insights gives administrators the ability to drill down into file shares and object stores across locations and sites, including relevant metrics by department, division or business unit, such as:
- Which shares have the greatest amount of cold data?
- Which shares have the highest recent growth in new data?
- Which shares have the highest recent growth overall?
- Which file servers have the least free space available?
- Which shares have tiered the most data?
One Komprise customer put it this way:
“It’s a single interface that will show us important metrics like capacity usage in every storage location, which will save us a lot of time and ensure we make the right decisions for our departments and users.”
