XIO X-Bricks Test

An X-Brick is the basic building block of an XtremIO array. Each X-Brick is comprised of:

  • One 2U Disk Array Enclosure (DAE), containing:

    • 25 eMLC SSDs (standard X-Brick) or 13 eMLC SSDs (10TB Starter X-Brick [5TB])
    • Two redundant power supply units (PSUs)
    • Two redundant SAS interconnect modules
  • One Battery Backup Unit

  • Two 1U Storage Controllers (redundant storage processors) which includes,

    • Two redundant power supply units (PSUs)
    • Two 8Gb/s Fiber Channel (FC) ports
    • Two 10GbE iSCSI ports
    • Two 40Gb/s InfiniBand ports
    • One 1Gb/s management/IPMI port

This test monitors the current state of each X-Brick and also reports the number of SSDs and BBUs available in each X-Brick.

Target of the test : An EMC XtremIO Storage array

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each X-Brick of the target EMC XtremIO being monitored

Configurable parameters for the test
Parameters Description

Test period

How often should the test be executed

Host

The IP address of the storage array

Port

The port number at which the storage array listens. The default is NULL.

XtremIO User and XtremIO Password

Provide the credentials of a user who has read only privileges to access the XtremIO storage array in the XtremIO User and XtremIO Password text boxes.

Confirm Password

Confirm the password by retyping it here.

XMS IP

This parameter is applicable only for EMC XtremIO 4.x. By default, None will be chosen from this list. If the target EMC XtremIO storage array is within a XMS Management Server that is auto-discovered, then the IP or host name of that XMS Management Server will be displayed in this list. Select that particular XMS IP to configure this test. If you wish to monitor an EMC XtremIO Storage Array that is either not an integral part of the auto-discovered XMS Management Server or a brand new EMC XtremIO Storage Array, choose the Other option. This will enable you to add a new XMS Managament Server. To know how to add a new XMS Management Server, refer to Adding a new XMS.

SSL

The eG agent collects performance metrics by invoking Restful APIs on the target Storage array. Typically, the Restful APIs can be invoked through the HTTP or the HTTPS mode. By default, the eG agent invokes the Restful APIs using the HTTPS mode. This is why, the SSL flag is set to Yes by default. If the target storage array is not SSL-enabled, then the Restful APIs can be accessed through the HTTP mode only. In this case, set the SSL flag to No.
Measurements made by the test
Measurement   Measurement Unit Interpretation

X-Brick state

Indicates the current state of this X-Brick.

 

The values reported by this measure and their numeric equivalents are available in the table below:

Measure Value Numeric Value
In sys 0
Unknown 1

Note:

This measure reports the Measure Values listed in the table above to indicate the state of this X-Brick. However, in the graph, this measure is indicated using the Numeric Values listed in the above table.

Number of SSDs

Indicates the total number of SSDs in this X-Brick.

Number

 

Number of BBUs

Indicates the number of Battery Backup units in this X-Brick.

Number

If the value of this measure is 1 then this X-Brick is a stand-alone X-Brick. If the value of this measure is 2 then this X-Brick is a single X-Brick cluster.
