Welcome to Dell Technologies Elastic Cloud Storage (ECS) - How to Series.
ECS: Capacity dashboard and Command Line Interface (CLI) walk-through. Reference Dell Knowledge Article number 20748.
This video was created to: Give a brief overview of the Capacity Usage Dashboard in ECS, to show where the forecasts are, and the history trend graphs, and will be demonstrated using the Web User Interface and Command Line Interface (CLI).
This video presents the following: Logging in to the Web User Interface. Show the main Capacity window. The forecasts and how to interpret the forecasts.
Trends on capacity and cleaning. Logged in as admin on the CLI, run the following "svc" commands. Please take a moment to review the commands listed.
Before you begin: Have appropriate credentials, usually root for the Web User Interface and admin for CLI access to the host. Have an SSH Client (e.g. PuTTY) installed.
Demonstration of Capacity Web User Interface Dashboard and CLI. Login to the GUI. The main dashboard for capacity shows "Reserved", Available, and "Used".
The capacity dashboard shows a forecast that is based on ingest rates over different time periods. You can use the filter to set time range for the charts.
This can be quite slow as it redraws the entire page. I will show a quicker method later in the demo. Click on the "History" tab. Click on the report name.
This allows you to see a detailed timeline. You can also change or set the time filter here, which will be quicker redrawing the graph.
The "Used Capacity" dashboard shows the amount of each data used. Under "Garbage Collection", garbage detected will show "Capacity Pending Reclamation".
It will also show total capacity that has been reclaimed on the appliance. Capacity Reclaimed shows the different categories of space reclaimed.
Set the timeframe under the "History" for faster redraw of graphs. svc_vdc capacity shows the overall usage. If the nodes "Used Percent" are not all similar, please contact Dell Support to help investigate the root cause. svc_vdc trend shows, by default, the last eight days.
svc_gc shows garbage collection information. See the ECS Troubleshooting Guide for more information on all of these commands. This "Capacity Utilization" screen shows what the forecasts would look like once you pass 80% full.
The system will go "READ-ONLY" between 85–90% based on reserved space. Unreclaimable garbage less than 15% of total used is normal, i.e. these blocks have not met the threshold level to be reclaimable yet.
When purchasing additional capacity, plan for the following: Business/Data Growth expectations. Internal procurement procedures. Logistical and installation times.

Thank you for watching.
