This guide explains how to install the rack-mounted EXA 5200 recordstore.

Installation prerequisites

To install the recordstore, your environment must meet the following requirements:
Recordstore
2U of rack space and 2x750W of power
Management
One 10/100/1000 BASE-T network port or one 10G BASE-SR port for recordstore management.
Network Access
TCP port 443 must be open between the recordstore and any connected sensors and consoles as well as any system that connects to the recordstore for administration.
TCP port 9443 must be open to enable recordstore nodes to communicate within the same cluster.

For more information about the interfaces on the ExtraHop system, see the ExtraHop Hardware FAQ.

Rear panel ports

EXA 5200

  • One iDRAC port
  • One RS-232 serial port to connect a console device
  • One VGA port to connect an external display
  • Two USB 3.0 ports to connect input devices such as a keyboard and mouse
  • Two 10 GbE ports. Ports 1 and 2 can be configured as a management port.
  • Two 10/100/1000 BASE-T network ports. Port 3 is the primary management port.
  • Two power ports to connect the recordstore to an AC power source

Set up the recordstore

  1. Rack mount the recordstore.
    Install the recordstore in your data center with the included rack-mounting kit. The mounting kit supports most four-post racks with either round or square holes.

    Orient the hardware to ensure proper airflow. The cold air intake is through the front of the recordstore.

  2. Connect port 3 to your management network.
    The EXA 5200 recordstore has two 10/100/1000 BASE-T network ports. With a network patch cable, connect the management port on the EXA 5200 to your management network. Port 3 is the default management port on the EXA 5200.
  3. (Optional): Connect the iDRAC port.
    To enable remote management of the recordstore, connect your management network to the iDRAC port with a network patch cable.
  4. (Optional): Connect a 10 GbE port.
    Connect one of the 10 GbE ports on the recordstore with a 10 GbE cable to your network to manage the EXA 5200.
  5. Install the front bezel.
    You must install the front bezel if you want to configure the recordstore through the LCD display.

    Insert the USB connector on the right side of the bezel into the USB port on the front of the recordstore. Press and hold the release button on the left end of the bezel and push the bezel flush with the recordstore until it snaps into place.

  6. Connect the power cords.
    Connect the two supplied power cords to the power supplies on the back of the recordstore, and then plug the cords into a power outlet. If the recordstore does not power on automatically, press the power button on the front-right of the recordstore.

Configure the management IP address

DHCP is enabled by default on the ExtraHop system. When you power on the system, interface 3 attempts to acquire an IP address through DHCP. If successful, the IP address appears on the home screen of the LCD.

If your network does not support DHCP, you can configure a static IP address through the LCD menu on the front panel or through the command-line interface (CLI).

Important:For deployments that include a sensor that is connected to an ECA VM console, we strongly recommend configuring a unique hostname. If the IP address on the sensor is changed, the console can re-establish connection easily to the sensor by hostname.

Configure a static IP address through the LCD

Complete the following steps to manually configure an IP address through the front panel LCD controls.
  1. Make sure that the default management interface is connected to the network and the link status is active.
  2. Press the select button (✓) to begin.
  3. Press the down arrow button to select Network, and then press the select button.
  4. Press the down arrow to select Set static IP, and then press the select button.
  5. Press the left or right arrows to select the first digit to change, and then press the up or down arrows to change the digit to the desired number.
    Repeat this step for each digit you need to change. After you configure the desired IP address, press the select button.
  6. On the Network mask screen, press the left or right arrows to select the first digit to change, and then press the up or down arrows to change the digit to the desired number.

    take_settings 3
  10. Type Y to proceed and then press ENTER.

Create a recordstore cluster

For the best performance, data redundancy, and stability, you must configure at least three recordstores in a cluster.

Important:If you are creating a recordstore cluster with six or more nodes, you must configure the cluster with manager nodes. For manager node instructions, see Deploying manager nodes.

In the following example, the recordstores have the following IP addresses:

  • Node 1: 10.20.227.177
  • Node 2: 10.20.227.178
  • Node 3: 10.20.227.179

You will join nodes 2 and 3 to node 1 to create the recordstore cluster. All three nodes are data nodes. You cannot join a data node to a manager node or join a manager node to a data node to create a cluster.

Important:Each node that you join must have the same configuration (physical or virtual) and the same ExtraHop firmware version. EXA 5100 and EXA 5200 physical recordstores can be in the same cluster.

Before you begin

You must have already installed or provisioned the recordstores in your environment before proceeding.
  1. Log in to the Administration settings on all three recordstores with the setup user account in three separate browser windows or tabs.
  2. Select the browser window of node 1.
  3. In the Status and Diagnostics section, click Fingerprint and note the fingerprint value. You will later confirm that the fingerprint for node 1 matches when you join the remaining two nodes.
  4. Select the browser window of node 2.
  5. In the Explore Cluster Settings section, click Join Cluster.
  6. In the Host field, type the hostname or IP address of data node 1 and then click Continue.
    Note:For cloud-based deployments, be sure to type the IP address listed in the Interfaces table on the Connectivity page.
  7. Confirm that the fingerprint on this page matches the fingerprint you noted in step 3.
  8. In the Setup Password field, type the password for the node 1 setup user account and then click Join.
    When the join is complete, the Explore Cluster Settings section has two new entries: Cluster Members and Cluster Data Management.
  9. Click Cluster Members. You should see node 1 and node 2 in the list.
  10. In the Status and Diagnostics section, click Explore Cluster Status. Wait for the Status field to change to Green before adding the next node.
  11. Repeat steps 5 - 10 to join each additional node to the new cluster.
    Note:To avoid creating multiple clusters, always join a new node to an existing cluster and not to another single appliance.
  12. When you have added all of your recordstores to the cluster, click Cluster Members in the Explore Cluster Settings section. You should see all of the joined nodes in the list, similar to the following figure.
  13. In the Explore Cluster Settings section, click Cluster Data Management and make sure that Replication Level is set to 1 and Shard Reallocation is ON.
