EMC Storage Analytics Dashboards

VNX Overview dashboard

Click the VNX Overview tab to view a collection of heat maps that provide a single view of the performance and capacity for all VNX resources with configured adapter instances.

Heat maps on this dashboard group the contents by adapter instance.

The VNX Overview dashboard displays the following heat maps:

CPU performance

This heat map displays the CPU utilization of each Storage Processor and Data

Mover on each configured adapter instance. The color of the heat map entries shows percentage busy: l

Green indicates 0% busy.

l

Red indicates 100% busy.

FAST cache performance

This heat map has two modes: Read Cache Hit Ratio and Write Cache Hit Ratio. To select the mode, use the Configuration menu. The Read/Write Cache Hit Ratio (%) is the number of FAST Cache read or write hits divided by the total number of read or write I/Os across all RG LUNs and Pools configured to use FAST Cache. The color of the heat map entries shows hit ratios: l

Green indicates a high FAST Cache hit ratio.

l l

Red indicates a low FAST Cache hit ratio. A low value on an idle array is acceptable.

Gray indicates that there is no FAST Cache present on the VNX systems identified by the adapter instances and a Heat Map not configured message appears with the heat map.

Pool capacity

This heat map has four modes: RAID Group Available Capacity, Storage Pool Capacity

Utilization, Storage Pool Available Capacity, and File Pool Available Capacity.

In Capacity Utilization mode, the color of the heat map entries shows the value of the percentage full metric for all non-RAID Group storage pools: l

Green indicates 0% full.

l

Red indicates 100% full.

In Available Capacity mode, the color of the heap map entries shows the value of the

Available Capacity (GB) metric: l l

Green indicates the largest available capacity on any storage pool for any of the configured adapter instances.

Red indicates 0 GB available.

LUN and file system performance

This heat map has several modes.

In LUN Utilization mode, the color of the heat map entries show the percentage busy metric for all LUNs grouped by adapter instance: l

Green indicates 0% busy.

Red indicates 100% busy.

In LUN Latency mode, the color of the heat map entries shows the value of the

Latency (ms) metric: l

Green indicates 0 ms latency.

l

Red indicates 20 ms or greater latency and is configurable.

Latency values appear for RAID Group LUNs. Pool LUNS appear in white with no latency values reported.

In LUN Read IOPs mode, the color of the heat map entries shows the relative number of read I/O operations per second serviced by the LUN. The color ranges from light green to dark green. Dark green indicates the highest number of read I/O operations per second serviced by any LUN listed in the heat map.

In LUN Write IOPS mode, the color of the heat map entries shows the relative number of write I/O operations per second serviced by the LUN. The color ranges from light green to dark green. Dark green indicates the highest number of write I/O operations per second serviced by any LUN listed in the heat map.

In File System Read IOPs mode, the color of the heat map shows the relative number of read I/O operations per second serviced by the file system. The color ranges from light green to dark green. Dark green indicates the highest number of read I/O operations per second serviced by any file system listed in the heat map.

In File System Write IOPS mode, the color of the heat map entries shows the relative number of write I/O operations per second serviced by the file system. The color ranges from light green to dark green. Dark green indicates the highest number of write I/O operations per second serviced by any file system listed in the heat map.
