See the site planning and requirements documentation for the hardware components that make up the StorNext environment (for example, appliance server, storage, tape library) to understand the hardware-specific requirements.
Review the following sections to understand the network configuration that must be in place for a successful StorNext Connect installation.
Domain Name System (DNS) is recommended for hostname resolution. If the environment does not have a DNS server, use IP addresses—not hostnames—to identify system services (such as NTP and SMTP) and clients, which ensures resolution with the StorNext Connect system.
At least one DNS server, but no more than three, can be set for the management network. Make sure consistent valid lookup of hostnames is available on the metadata network. If hostname resolution is not met, discovery may not be able to find all nodes in the StorNext Connect workspaces, and it is likely that data for some nodes will not appear in the applications.
You can run the command
nslookup to query the configured domain name server and return the IP address for a domain name (or vice versa). For example:
Ensure that you have a dedicated Network Time Protocol (NTP) server in place. Quantum strongly recommends using an NTP server to:
- Keep the time synchronized between different components and data shared within the StorNext workspace (cluster).
- Alleviate data mismatches caused by incorrect time stamps between both nodes of an HA server pair and the metadata on their shared file system.
- Keep the date and time between the two server nodes of an HA server pair consistent, and thus keep HA reliable.
- Ensure consistent time synchronization and communication between connected Quantum products.
To avoid errors, it is critical that all the server nodes and other components that capture time stamps and operate in the same network are synchronized to the same time. If an Internet connection is available, we recommend you use a public NTP server pool. If there is no outside connection available, set up an internal NTP server on another node and use that server as the NTP server. That way the time and date stamps for data will be consistent.
If the environment does not have a DNS server, use the IP address—not hostname—if configuring NTP.
NTP is not required for single-node appliances. However, if NTP is not configured, and client stats are transmitted with a time that is later than the time on the StorNext Connect system, the stats are discarded and StorNext Connect does not report accurate monitoring stats.
Separate IP networks are required for system management and metadata when performing initial configuration of a Quantum appliance using the Install app. Not applicable to deployments of StorNext Connect to operational Quantum appliances.
When you install and configure a new system using the Install application, the network configuration is a dual network configuration. A dual network configuration is a management network and a separate metadata network, where the File System Name Servers (fsnameservers) and high availability (HA) network are on the metadata network. StorNext Connect does not support a mix, where the fsnameservers are assigned to the management network and the HA network is on a separate metadata network.
If Quantum Professional Services or a Quantum Service Partner installs StorNext Connect on an existing system that was previously installed and configured, StorNext Connect can support either a dual network configuration or a single network configuration. A single network configuration is a management network only (fsnameservers and HA network) with no dedicated metadata network. If the system requires fsnameservers on the management network (for example, LAN clients), then the HA peer IP addresses must also be on the management network. This configuration is required so that the StorNext Connect Dashboard and other monitoring applications display data for StorNext clients in the workspace (cluster).
For additional information about fsnameservers and HA systems, see the StorNext Documentation Center.
The Install app requires you to provide a management gateway, but the existence of the gateway is optional. If you do not have a management gateway for StorNext Connect, you can enter any IP address within the management network netmask range.
The Install app requires cabling the appliance node(s) and QXS RAID array to a network switch, even if the environment does not have a management gateway or the switch is isolated from the network. You can use an Ethernet switch as a temporary management network to complete installation. The switch needs to be connected to power, with a minimum of five ports available.
Similarly, you can use an Ethernet switch as a temporary metadata network. The Install app tests the Ethernet ports to make sure you have a cable. The switch for the management network can be reused. After the Install app verification, you can remove the cable if desired.
The QXS RAID array IP addresses must be on the same management subnet as the appliance.
Simple Mail Transfer Protocol (SMTP) is recommended but not required. If an SMTP server is not configured, StorNext Connect cannot send password recovery emails.
If the environment does not have a DNS server, use the IP address—not hostname—if configuring SMTP.
A StorNext virtual IP (VIP) address is optional when using the Install app. However, a VIP is required for some StorNext services, such as replication. If a VIP is required for the system and you do not configure it during installation, the setting will need to be configured manually through the command line interface.
If an AEL library is present, the library needs to be on a separate Fibre Channel network to prevent scans interrupting tape operations. This is a standard library configuration requirement. It can either be a separate fabric or just zoned independently.
- StorNext Connect does not provide health monitoring for StorNext QD-, QM-, and QS-Series storage. This means that the Storage Arrays widget on the Dashboard will not have data in it.
- The StorNext M330 Metadata Appliance can be discovered and monitored from a StorNext Connect system. An M330 Metadata Appliance cannot function as a StorNext Connect system. The Install application is not supported on the M330.
If it is to be discovered and monitored, an M330 needs to follow the same prerequisites and compatibility rules in the Planning and Compatibility section.Quantum Professional Services installation with a reviewed and approved site configuration is required.
