ProbeNAS

ProbeNAS supports 10G Ethernet ingress/egress traffic for NFSv3 protocols running over TCP/IPv4, and aggregated data-plane links formed by common Link Aggregation methods such as IEEE 802.1AX/802.3ad or Cisco EtherChannel. It does not process Out of Order traffic, but collects occurrence counts per flow.

ProbeNAS enables monitoring for SMBv2/3-based storage and is supported by the following entities: SMB Conversation and SMB File System.

ProbeNAS also enables monitoring traffic for iSCSI protocol and is supported by the following entity: iSCSI Conversation.

Please note: ProbeNAS can provide TCP flow metrics (e.g. TCP Window Close Alerts) related to NFS traffic. It does not provide these TCP flow metrics for other traffic, even if it is NAS traffic (ISCSI or SMB).

Power supply units (PSUs) in NAS and SAN probes are numbered 1 and 2, from left to right, as viewed when facing the back panel. The PSUs are hot-swappable.

Follow these steps to create a ProbeNAS.

  1. From the Settings page, click Performance Probe Inventory.

    The Performance Probe Inventory page is displayed.

    The column headings are defined in the following table:

    Table 74. Performance Probe Inventory Parameters

    Column Heading

    Definition

    Probe Name

    The name you assign to the probe

    IP Address

    IP address of the probe

    Probe Type

    Type of hardware probe, for example, ProbeNAS

    Status

    Status of the probe: Subscribed, Unsubscribed, or Faulted (subscribed, but not receiving data).

    Version

    Firmware version, for example, 5.4.2

    Messages

    Status information

    Unassociated Links

    Number of “unassociated links” (links that IO is unable to autoplace), this value is a whole number.



  2. Select ProbeNAS from the New dropdown menu.

    The Discover New Probe page displays.

  3. Enter the IP address of the probe and click Next.

    The Create New Probe page is displayed, populated with information discovered about the probe at the specified IP address. Use the scroll bar to display the full page.

    You can use the IO UI to change a Performance Probe’s IP address if the initial configuration (Initial IP) is already set. IP addresses can be changed if the old and new IP addresses can be routed from the appliance.

    Except for the Subscription status, the probe information on the page is auto-detected from the hardware probe configuration, which was entered from either the probe LCD screen or the probe Configuration Wizard.

    Descriptions of the parameters on this page are as follows:

    Table 75. Create Hardware Probe Parameters

    Parameter

    Description

    Probe Name

    Specified during creation

    PID

    Probe ID

    Probe Type

    Type of probe: ProbeNAS

    Version

    Firmware version of the probe

    Network Address

    Network settings (static or DHCP) of the probe

    NTP Server Address

    NTP server configuration for the probe, can specify up to three

    DNS

    DNS server setting for the probe, typically two

    MAC Address

    Network port MAC address

    Subscription

    Subscribe or unsubscribe the probe, values are Subscribed (default) or Unsubscribed

    Enable Locator LED

    Enable the locator LED on the probe

    TCP Window Close Threshold

    Integer value in bytes at which an alert is posted, and displayed in the upper right corner of the page (default=4096)



    The following are descriptions for the column headings in the Ports section of the page:

    Table 76. Column Headings in the Ports Section

    Column Heading

    Definition

    Port

    Port Number (1-16, can be toggled ascending/descending)

    Link License

    Type of license: Auto Assign, None, 10G Active, 10G Passive

    Auto Assign chooses 10G Active licenses first, unless 10G Passive is specified.

    Configured Speed

    10G only

    Current Speed

    10G only

    Filer Type

    This setting only applies to NFS.

    OS of file server: None, VNX, Isilon, NetApp, Linux, FreeBSD, Solaris

    LAG Group

    Link Aggregation Group: ports in LAGs must be assigned within a set of probe-port groups.



  4. Choose the Link License for each selected port by clicking on the corresponding Link License column and choosing the link license value from the drop down menu.

    Auto Assign chooses 10G Active licenses unless 10G Passive is specified, until no more Active licenses are available. If no more Active licenses are available, Passive licenses are assigned.

    Active/passive threshold: Sa port with traffic that is > 100KB/sec = active.

  5. Choose the Configured Speed for each selected port by clicking on the corresponding Configured Speed column and choosing the configured speed from the drop down menu.

    Only 10G is currently supported.

  6. Specify (optional) Link Aggregation Groups (LAGs).

    A port can be a member of only one LAG, and at least two ports comprise a LAG:

    • LAG 0/1, Ports 1-4

    • LAG 2/3, Ports 5-8

    • LAG 4/5, Ports 9-12

    • LAG 6/7, Ports 13-16

    If LAG assignments are changed, the probe must be rebooted.

  7. Verify that the settings that you chose as well as the pre-populated ones are correct.

  8. Click Save on the Create New Probe page to commit the changes and create the new hardware probe.

    The Performance Probe Inventory page displays, with your newly created probe listed in the inventory.
