Storage Details

Storage by Data Center

The Storage by Data Center report gives you a breakdown of all your data centers within your enterprise.

The dashboard at the top will draw one gauge for each data center. Each gauge displays the percent used of usable. To make this data easy to scan, we’ve color-coded the ranges:

Color	Range
Teal	0-49%
Blue	50-69%
Yellow	70-79%
Red	80-100%

If you have a lot of data centers, you may need to scroll horizontally to see them all.

On the lower left, you’ll find a stacked bar graph showing you the breakdown of provisioned space by data center.

Remember, our graphs are interactive! Check out the many ways you can slice and dice the visuals in VSI by reading up on our interactive features.

On the lower right you’ll see a table containing the statistics showing in the stacked bar chart to it’s left.

Field	What It Means	How Its Calculated
Data Center	Shows the name of the data center as it appears within your business unit data	N/A
Total Used	The total amount of space currently in use	Sum of the used space for each system within a given data center.
Provisioned Free	Represents the total amount of space you’ve provisioned, but that isn’t currently in use.	Sum of the provisioned free space within a given data center.
Unprovisioned Free	Represents the total amount of space within the data center that hasn’t been provisioned for use.	Sum of the unprovisioned free space within a given data center.
Overprovisioned	This shows the total amount of space within the data center that has been over-provisioned. Overprovisioning is a normal and acceptable practice.	Sum of the overprovisioned space within a given data center.

Storage by Tier

Similar to Storage by Data Center, this report shows a breakdown of storage based in your defined tiers. Tier 1 storage is typically your fast, expensive storage suitable for production workloads. Tier 2 is middle tier in performance and suitable for normal operations. Tier 3 is usually cheaper disk space used for archival storage. Tiers can be defined in your business unit data. The gauges at the top show the utilization for each tier. The stacked column graph in the lower left shows how your tiered storage is provisioned. To the lower right, the table shows the data supported the graph on the left.

The gauges at the top are color coded for easy scanning:

Color	Range
Teal	0-49%
Blue	50-69%
Yellow	70-79%
Red	80-100%

Storage by Device Type

This report shows your storage split out by device type. The gauges at the top will show you each device type in use within your organization. If you have a heterogeneous environment you may have to scroll horizontally to see everything. As with the other “Storage by” reports, we see a stacked column graph in the lower left displaying provisioning data for each device type. The supporting data for this graph is displayed in the table at the lower right.

The gauges at the top are color coded for easy scanning:

Storage by Classification

Storage by Classification shows you a breakdown of your storage based on a classification defined in your organization’s business unit settings. The gauges at the top show you utilization levels for each classification. The graph in the lower left shows how each classification is provisioned, while the supporting data for the graph appears within the table in the lower right.

The gauges at the top are color coded for easy scanning. If you have a lot of classifications, you may need to scroll horizontally to see everything.

Free Space by Device

This report is designed to help you find free space within the enterprise. Do you have a big project about to start? This report helps you find a place to put it. I can also show you storage fragmentation at the enterprise level. The pie chart in the top left shows you the largest amount of contiguous free space available on each array.

The column chart at upper right shows you the largest contiguous along with the overall free space for that system.

The customizable data grid at the bottom of the report shows the supporting data in tabular format. Double-click any row in the grid to view the Free Space by Disk Group Report at the device level.

Disk Type by Storage Array

The Enterprise Disk Type by Storage Array report reflects the types of disk that are located on the storage array and graphically demonstrates the allocation of each type on the array. The top half of the report is a stacked bar graph showing your used storage on that device split out by device type. The legend at the bottom indicates the color keying for each device type. The black “unknown” type usually indicates some mixture of device types that don’t fit into a homogeneous category.

Beneath the graph is the customizable data grid that shows the supporting data for the graph.

Monthly Performance

Monthly Performance shows you changes in used space and IOPs for each device type in your enterprise. This report has a graph at the top showing a column chart. The used statistics are graphed in orange while the performance (IOPs) statistic is graphed in blue. This chart can show positive as well as negative changes. Your utilization and performance will ebb and tide like a financial stock price. Some months it’s up while others it’s down. This report shows you this one month at a time. We have trend reports that show you these kinds of trends over time but this report is unique in that it focuses on a single month at a time.

Field	What It Means	How Its Calculated
Group (Device Type)	This report comes pre-grouped by device type.	N/A
Device Name	The name of the device	N/A
Classification	The classification for the device.	Classifications are defined in your organization’s business unit data.
sum((Usable End)	The report is pre-grouped, so this field is presenting the sum of the usable space present at the latest collection date for the month.	We sum all the usable space within a device type at the end of the month.
sum(Used Growth)	The report is pre-grouped, so this field is presenting the sum of Used Growth grouped by device type. It’s telling you how much your capacity changed since last month.	Used growth is computed by subtracting this month’s used from last month’s used.
weighted-avg(% Used Growth)	This field is showing you the weighted average for percentage of growth in your used space between months. It’s essentially the used growth expressed as a percentage rather than a unit of space like GiB.	A weighted average is used to smooth out any skewing effects of any major outliers.
sum(IOPS End)	This grouped field is summing your IOPs at the end of the month.	This is a sum of your IOPs by device type.
sum(IOPs Growth)	The sum of your IOPs growth grouped by device type. It’s telling you how much your performance changed versus last month across all devices of the device type.	Growth is computed by subtracting the current month’s IOPs from the previous month’s. These results are summed.
weighted-avg(Latency Change)	The weighted average latency change since the last month. It tells you how much your performance latency rose or fell this month versus last month.	A weighted average is used to smooth out any skewing effects of any major outliers.
