Do not update the appliance BIOS, as it may cause issues with appliance
functionality.
If you want to deploy a Data Store, you must have at least 3 Data Nodes. A Data Store
6200 with 3 Data Nodes can handle roughly 500,000 flows per second, and retain that
data for roughly 90 days. You can extend your Data Store with additional Data Nodes in
multiples of 3, up to a maximum of 36 Data Nodes.
These recommendations consider only telemetry. Your performance may vary
depending on additional factors, including host count, flow sensor use, traffic
profiles, and other network characteristics. Contact Cisco Support for
assistance with sizing.
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 deploy an SMC with your Data Store, and configure it for use with a Data
Store. If you want high availability for your SMC, you can also deploy a failover SMC.
In addition, you must deploy at least 1 Flow Collector with your Data Store, and
configure the Flow Collectors for use with a Data Store.
For each SMCand Flow Collector that you deploy, you must assign a public routable
IPaddress to the eth0 management port. When deploying a Data Store, you can
configure the use of a BASE-T copper 1G/10Gport or SFP+ twinax cable 10Gport for
the SMC and Flow Collector eth0 management port. Cisco requires 10Gthroughput for
the BASE-Tcopper port for Data Store use. Users not deploying a Data Store can only
configure the 100Mbps/1Gbps/10 Gbps copper interface as eth0.
You can also deploy Flow Sensors and UDPDirectors for your Stealthwatch deployment.
Because these appliances do not communicate directly with the Data Store, you do not
need to configure them for use with a Data Store.
See the relevant Specification Sheets for more information on the supported platforms.
See the Stealthwatch Hardware and Software Version Compatibility Matrix for more
information on version compatibility.
The Data Store supports Flow Sensors and UDPDirectors in v7.3.1 or v7.3.2. You are
not required to deploy either with a Data Store. If you add an appliance to your cluster,
make sure your appliances all have the same version installed.
