Investigating a Directory

In Isilon storage arrays, directories are mounted by datastores. The data displayed in the dashboard reflects values for the directory over the selected time range. The Directory dashboard has one tab.

To explore a directory:
1
On a dashboard, click a directory name.
The Directory dashboard opens.
2
Review overall performance in the Summary tab.
•
Details. Displays the directory’s status, physical details, and parent device.
•
Topology. Displays the connections from datastores to the selected directory.
3
To investigate further, click an icon to see more detail about the entity it represents, and if desired, select a component name in the detailed view to navigate to the dashboard for that component.

Investigating an EqualLogic Member

Investigating an EqualLogic Member

The data displayed in the dashboard reflects values for the selected EqualLogic array member over the time range. This walkthrough describes the contents of each of the tabs.

To explore an EqualLogic member:
1
In a topology diagram or from the EqualLogic Storage Array dashboard, click an array member name.
The Member Node dashboard opens.
2
Review overall performance in the Summary tab.
•
Related Inventory. Displays a list of components from the perspective of the member (rather than the storage array).
•
Resource Utilization charts. Compares resources used by the member against resources used by the pool.
- Capacity Summary charts. Displays Used Capacity and Available Usable Capacity.
- Data Rate charts. Plots values for Data Read Rate and Data Write Rate.
- Ops Rate charts. Plots values for Read Ops Rate and Write Ops Rate.
- Latency charts. Plots values for Read Latency and Write Latency.
•
Member Network Load. Plots the member’s Send Util and Rcv Util over the time period.
•
Summary and Resource Information. Displays physical details about the member.
•
Alarm Summary. Displays alarms on the member.
3
Click the Network tab.
Displays the same information as the Network tab on the EqualLogic Storage Array dashboard, but the data reflects only the selected member.
4
Click the Disks tab.
Displays only the disks used by the selected member.

Investigating an FC Switch Port

The data displayed in the dashboard reflects values for the component over the selected time range. This walkthrough describes the contents of each of the tabs.

 
* 
NOTE: If the port is a Brocade logical ISL, no metrics are available.
To explore a switch port:
1
On a dashboard, click an FC switch port.
The FC Switch Port dashboard opens.
2
Review overall performance in the Summary tab.
•
Details. Displays the port’s status, physical details, parent switch, parent fabric, VSAN (if applicable), and current values for Data Rate, Frame Rate, Link Error Rate, and Non-Link Error Rate. Click a Sparkline to plot metric values over the time period.
•
Charts. Charts plot the following metric pairs over the time period:
- Data Rate. Plots values for Data Receive Rate and Data Send Rate.
- Utilization. Plots values for Rcvd Utilization and Xmit Utilization.
- Frame Rate. Plots values for Frame Receive Rate and Frame Send Rate.
- Errors. Plots values for Link Error Rate and Non-Link Error Rate.
•
Alarm Summary. Displays alarms on the port.
3
Click the Topology tab.
The contents of this tab depends on the type of port selected.
ISL Port:
•
Switch-to-Switch Connectivity diagram. Displays the selected ISL port (left box) and its connection to another ISL port (right box). Click a port icon for details about the device connected to the port.
•
Topology Table (Inter-Switch Connections). Identifies all ISL port connections from this port’s parent switch to other switches in the fabric.
N Port:
•
Basic Connectivity (table). Displays the ESX hosts and/or physical hosts connected to the selected N port through their host ports. An N port can have connections to multiple host ports using NPV technology.
 
* 
TIP: If hosts in the Host Name column are (unknown), you may be able to use dependency processing to infer the host names associated with the host ports. For instructions, see Inferring Physical-Host-to-Storage Relationships.
•
Basic Connectivity (diagram). Displays the selected N port (left box) and its connection to a filer or storage array port (right box). Click a port icon for details about the device connected to the port.
•
Select Host Port(s). Controls the set of hosts displayed in the Port Dependencies table.
•
Port Dependencies. On separate tabs, displays connections to LUNs (though the selected port) from virtual machines, ESX or Hyper-V servers, and physical hosts. If the selected port has problems or failures, the connected VMs or hosts may exhibit performance problems.

To investigate further:
•
Click a VSAN link and then select the name of the VSAN. Exploring a Cisco VSAN.
•
Click an alarm. See Assessing Storage Alarms.

Investigating an Isilon Node

The data displayed in the dashboard reflects values for the selected Isilon node over the time range. This walkthrough describes the contents of each of the tabs.

To explore an Isilon node:
1
In a topology diagram or from the Isilon Storage Array dashboard, click a member node name.
The Member Node dashboard opens.
2
Review overall performance in the Summary tab.
•
Related Inventory. Displays a list of components from the perspective of the member node (rather than the storage array).
•
IFS Capacity. The chart displays IFS Capacity: Free and IFS Capacity Used for the IFS file system. In addition, the total capacity is broken down into hard disk drive and solid state drives metrics as follows:
- Total. IFS Capacity: Total and IFS Capacity: Free
- HDD. IFS Capacity: HDD Total and IFS Capacity: HDD Free
- SSD. IFS Capacity: SDD Total and IFS Capacity: SDD Free
•
Node Network Load. Charts plot the following metric pairs:
- External Network Throughput. Plots the Send Data Rate and Rcv Data Rate for the external network over the time period.
 
* 
TIP: If you prefer to see the Send Util (% of max) and Rcv Util (% of max) based on the rated maximum speeds of the ports (actual port speeds are not available from Isilon arrays) in the external network, ask your Foglight for Storage Management Administrator to edit the registry variable StSAN_StoragePortShowUtilMax and set ISLN_E_IP=true.
- Internal Network Throughput. Plots values for Send Data Rate and Rcv Data Rate.
- Clients. Clients connected versus clients that are actively using the network.
•
Node Performance. Charts plot the following metrics for the selected node over the time period: % Busy, Latency, L1 Cache Hit Rate, L2 Cache Hit Rate, Data Read Rate, Data Write Rate, Read Ops Rate, and Write Ops Rate.
•
Summary and Resource Information. Displays physical details about the member node.
•
Alarm Summary. Displays alarms on the member node.
3
Click the Network tab.
Displays the same information as the Network tab on the Isilon Storage Array dashboard, but the data reflects only the selected member node. For more information, see EMC VPLEX Storage Array.
4
Click the Disks tab.
Displays disks used by the selected member. For more information, see Common Component Disk Tab Data.
