Deploy the ETA 9350 packetstore

This guide explains how to install the rack-mounted ETA 9350 packetstore.

Installation prerequisites

Important:For maximum performance and compatibility, deploy sensors and packetstores in the same datacenter.
To install the ETA 9350, your environment must meet the following requirements:
Appliance
2U of rack space and electrical connections for 2 x 800 W power supplies.
Management
One 10/100/1000 BASE-T network port or one 10G BASE-SR port for appliance management.
Monitoring (capture)
High performance interfaces: One to four network ports for connection to 25 GbE, or 10 GbE sources of packet data, depending on the ordered configuration.
Management + monitoring interfaces: One to three network ports for connection to 1 GbE sources of packet data.
Network Access
TCP 443 must be open between the packetstore and any connected console or sensors, including any system that connects to the system for administration.
Configure your firewall rules to allow outbound access over port 443 to ExtraHop Cloud Services.

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

Rear panel ports

  1. Power supply unit (PSU1) to connect the packetstore to an AC power source
  2. Two 25 GbE-capable ports on one network adapter. Ports 5 and 6 are the high-performance monitoring (capture) interfaces.
  3. Four SAS ports to connect extended storage units (ESU).
    Note:You cannot connect older ESUs to this packetstore.
  4. One RS-232 serial port to connect a console device
  5. Power supply unit (PSU2) to connect the packetstore to an AC power source
  6. One VGA port to connect an external display
  7. Two USB 3.0 ports to connect input devices such as a keyboard and mouse
  8. One iDRAC interface port
  9. Two 10 GbE ports. Ports 3 and 4 can be configured as a management port or management and RPCAP/ERSPAN/VXLAN/GENEVE target.
    Note:These ports function also as high-performance monitoring (capture) interfaces. Processing RPCAP, ERSPAN, VXLAN, and GENEVE traffic is limited to 1 Gbps per interface in "Management + RPCAP/ERSPAN/VXLAN/GENEVE" modes, but the ports support up to 10 Gbps per interface in Monitoring and High-Performance ERSPAN/VXLAN/GENEVE target modes.
  10. Two 10/100/1000 BASE-T network ports. Port 1 is the primary management port. These ports can be configured as a monitoring port, management port or management and RPCAP/ERSPAN/VXLAN/GENEVE target.
Tip:In environments with asymmetric routing adjacent to the high-performance interfaces, ping replies might not get back to the sender.

Set up the packetstore

  1. Rack mount the packetstore.
    Install the packetstore 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 packetstore.

  2. Connect port 1 to your management network.
    This appliance has four 10/100/1000 BASE-T network ports. With a network patch cable, connect the management port on the appliance to your management network. Port 1 is the default management port.
  3. Connect the monitoring port.
    With the appropriate network cable, connect a monitoring port on the appliance to a network tap or mirror port on the switch.
    Important:The ExtraHop packetstore requires a duplicate feed of the traffic that is sent to the ExtraHop sensor.
    Note:The link lights on the monitoring interface ports do not illuminate until you register the ExtraHop sensor, recordstore, or packetstore with your product key.
  4. Connect the iDRAC port.
    To enable remote management of the packetstore, connect your management network to the iDRAC port with a network patch cable.
  5. Install the front bezel.
    You must install the front bezel if you want to configure the packetstore through the LCD display.

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

  6. Connect any extended storage units (ESUs).
    For information about configuring extended storage units, see Add storage capacity to an ExtraHop packetstore.
    Note: With only one ESU, the ETA 9350 can achieve up to 10 Gbps throughput. At least two ESUs must be attached to the appliance to support 25 Gbps throughput, and at least four ESUs must be attached to support 50 Gbps. Packetstores can support a maximum of four ESUs.
  7. Connect the two supplied power cords to the power supply units (PSUs) on the back of the packetstore and two power cords to the PSUs on the back of the ESUs.
  8. Connect the power cords into an AC power receptacle.
    If the packetstore does not power on automatically, press the power button on the front-right of the packetstore.

Management IP address configuration

DHCP is enabled by default on the ExtraHop system. When you power on the system, the primary management interface 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:We strongly recommend configuring a unique hostname. If the system IP address changes, the ExtraHop console can re-establish connection easily to the system by hostname.
