Network administration

The following tables show the DataScale SN10-8R IP address assignments for the access network and the data network, as described in the SN10 version of the DataScale SN10-8R hardware installation document. Your company provides the subnets and host IP addresses in the Pre-Delivery Site Survey document before the DataScale SN10-8R is delivered and installed.

1. Network device administration

For general configuration and maintenance of the network devices in the DataScale SN10-8R (data switch, access switch, and serial console server), see the specific product administration documentation:

There should be minimal need to configure the serial console server and the Juniper access switch. For port connection details, see the SN10 version of the DataScale SN10-8R hardware installation document.

SambaNova highly recommends that you change the default passwords at first login. Use the following commands to initiate a password change on specified devices. Follow the prompts to create a new, secure password:

Juniper EX4300 access switch and QFX5200 data switch:

$ ssh root@<Juniper_switch_IP_address>
root@:RE:0% cli
root> configure
root# set system root-authentication plain-text-password

Lantronix SLC8000 serial console server:

$ ssh sysadmin@<Lantronix_switch_IP_address>
> set localusers password sysadmin

SambaNova provides patch release for these network devices, although a given patch does not always include new updates. You can download these patches from the SambaNova ext-infra-patch repository. See KB article #1062 "Listing and downloading available SN10-8R firmware" for details.

Patch release notes explain any steps that differ from the standard steps described in the product administration documentation.

2. IP address assignments for the access network

Table 1 shows the access network IP address assignments for components such as the BMC, the switch equipment, and the PDUs in the DataScale SN10-8R. The example IP addresses shown in the Example (10.0.1.0/26) column assume a customer provided a 10.0.1.0/26 subnet.

Reserved addresses and the broadcast IP address don’t have default usernames and passwords.
