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.
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 25. Performance Probe Inventory ParametersColumn 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.
Select ProbeNAS from the New dropdown menu.
The Discover New Probe page displays.
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 26. Create Hardware Probe ParametersParameter
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 27. Column Headings in the Ports SectionColumn 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.
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.
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.
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.
Verify that the settings that you chose as well as the pre-populated ones are correct.
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.
