Cisco Stealthwatch User Manual

(10 Gbps full duplex switched connection) between and
among your Data Nodes.
Data Node
Hardware Power
l If a hardware Data Node loses power unexpectedly, the data
can be corrupted. Use both power supplies on separate
circuits from uninterruptible power supplies.
l
When you initialize the Data Store cluster (see Data Store
Initialization and Configuration for more information),
alternate Data Node configuration based on the power
supplies that each Data Node uses. This can optimize fault
tolerance by minimizing the number of Data Nodes that go
down if power is lost.
Data Node
Switching
l Data Nodes require their own Layer 2 VLAN to allow inter-
Data Node communication. Hardware Data Nodes can be
connected to a shared or dedicated 10G switch.
l Cisco recommends that hardware Data Nodes be connected
to 2 switches to help ensure constant connectivity during
switch outages and upgrades. Due to the low latency
required for inter-Data Node communication, Cisco
recommends a redundant pair of switches, where the 2
switches are interconnected and carry the Layer 2 VLAN
across both switches.
Stealthwatch
Appliance
Communications
l SSHand SSHroot access required for SMC, Data Nodes,
and Flow Collectors, and configured from the SMC
l SMCand Flow Collectors must be able to reach all Data
Nodes
l Data Nodes must be able to reach SMC, all Flow Collectors,
and each Data Node
Note that you must obtain a Flow Rate (FPS) Smart License for your overall Stealthwatch
deployment.
Currently, the Data Store does not support deploying spare Data Nodes as
automatic replacements if a primary Data Node goes down. Contact Cisco
Support for guidance.
You must assign the following IP addresses to each Data Node:
