Overview of the SteelFusion Core Management Console : Using the SteelFusion Core Management Console : The Dashboard
  
The Dashboard
The Dashboard displays a dynamic, at-a-glance view of how your entire Edge and storage infrastructure is performing, organized in various panels. Data is refreshed every 60 seconds.
If you are upgrading to version 4.3, the Dashboard will appear after you clear your browser cache.
Note: On the RPO and Cache Efficiency panels, data is only available on Edges running version 4.3 and later.
The system health status icon and the system hostname are located in the upper-left corner of the Dashboard page. Hover the mouse over the icon to view the current system health status: Healthy, Degraded, or Critical.

Alarms
•  Alarms - Notifies you of any triggered Core alarms that require attention. There are two types of alarms: Critical or Degraded, and the number of triggered alarms appears on each tab. When the page is loaded, the Alarms panel displays the tab with the highest priority alarm by default. If both tabs contain active alarms, the Critical tab is shown by default. Click an alarm to view details on the Alarm Status page. Click More to view details on the Alarm Status page.
RPO and Cache Efficiency
•  RPO (Recovery Point Objective) - Summarizes the length of time since data from the Edges was last committed to the backend storage. For example, if the RPO is 3 hours this means that there is a 3 hour commit delay for data from the Edge to the Core, including any HA peers. These Average, Minimum, and Maximum values are taken across all connected Edges running version 4.3 and later. The Average value is useful as an overview of the average delay between the Edges and the Core, while the Maximum value can alert you to a specific Edge that is particularly behind. A lower RPO is desired, and the actual number depends on the infrastructure. Click More to view details on the SteelFusion Edge Stats page.
•  Cache Efficiency - Displays how efficiently SteelFusion’s prefetch mechanism reduces the traffic between the Edge and the Core. This value is the percentage of data that is served locally from the cache compared to data read from the data center storage array. These Average, Minimum, and Maximum percentages are calculated across all connected Edges in the infrastructure (including any HA peers).
Edge Overview
•  Edge Overview - Displays an overview of the Edges connected to the Core. Select the Blockstore Utilization tab to display the percentage of the blockstore currently being used at each Edge. Select the Uncommitted Data tab to display the percentage of blockstore data that is pending to be committed to the Core. Click More to view details on the SteelFusion Edges page.
Backend Storage and Edge Performance
•  Backend Storage Performance - Displays the performance statistics for all LUNs connected through this Core (and the peer Core, if HA is configured). This is an aggregate value across all LUNs and includes both iSCSI and Fibre Channel. Select the Latency tab to view the average read/write latencies for all LUNs in the last 30 minutes. Select the Throughput tab to view how much data has been written to and read from the LUNs in the last 30 minutes. In both tabs, select Read, Write, or Both to customize the view. Click More to view details on the LUN I/O Metrics page.
•  Edge Performance - Displays the last 30 minutes of performance, measured in total read and write throughput, for allEdges connected to this Core (and the peer Core, if HA is configured). Click Read, Write, or Both to customize the view. Click More to view details on the SteelFusion Edges page.
LUNs, Edges, High Availability, and Storage Summary
•  LUNs - Displays the total number of LUNs and their current health state: Normal, Degraded, Critical, or HA Peer Serving. In addition, this panel displays the features currently enabled or configured on these LUNs, such as prepopulation, snapshots, branch recovery, or whether the LUNs are mapped or pinned. If LUNs are not configured, click Add a LUN to add a LUN to this Core. Click More to view details on the LUNs page.
•  Edges - Displays the number of Edges and their connection status. The data shown is calculated across all Edges in the infrastructure (including the HA peer). If Edges are not configured, click Add an Edge to add an Edge to this Core. Click More to view details on the SteelFusion Edges page.
•  High Availability - Displays the failover peer’s IP address or name and its failover state (if high availability is configured). If high availability is not configured, click Add Failover Peer to add a peer. Click More to view details on the Failover Configuration page.
•  Storage Summary - Displays an overview of storage arrays connected to this Core, as well as their connection status. Click More to view details on the iSCSI, Initiators, MPIO page. The information in this panel will change depending on the type and number of connected storage arrays:
•  iSCSI and fibre channel - The name or IP address of one iSCSI storage array and the number of fibre channel LUNs.
•  iSCSI only - The name or IP address of up to two currently configured iSCSI storage arrays.
•  Fibre channel only - The number of fibre channel LUNs.
•  No iSCSI or fibre channel - Click Add a Storage Array to configure a storage array.
Navigating in the SteelFusion Core Management Console
You can access the tools and reports in the Core using cascading menus.
To display cascading menus
1. Click the name of the type of information that you want to access in the menu bar to display the submenus.
For example, click Reports to display the Storage and Diagnostics submenus. The menu item that is currently active is highlighted.
2. To go to a page, select the menu name you want to display.
For example, choose Configure > Manage: SteelFusion Edges to display the SteelFusion Edges page.
The following table summarizes the cascading menus.
