System requirements
Before you deploy NetScaler BLX, review the following requirements:
Supported Linux distributions
| Linux distribution | NetScaler BLX 14.1 | NetScaler BLX 13.1 | NetScaler BLX 13.0 |
|---|---|---|---|
| Red Hat Enterprise Linux (RHEL) 9.x | Yes | Yes | Yes |
| RHEL 8.x | Yes | Yes | Yes |
| RHEL 7.5 to 7.9 | Yes | Yes | Yes |
| CentOS 8.x | Yes | Yes | Yes |
| CentOS 7.5 to 7.9 | Yes | Yes | Yes |
| Oracle Linux 8.x | Yes | Yes | Yes |
| Oracle Linux 7.5 to 7.9 | Yes | Yes | Yes |
| Ubuntu 22.04 | Yes (Build 12.30 or later) | No | No |
| Ubuntu 20.04 | Yes | Yes | Yes |
| Ubuntu 18.04 | Yes | Yes | Yes |
| Oracle cloud Linux on Oracle Cloud Infrastructure (OCI) | Yes | Yes | Yes |
| Amazon Linux 2 | Yes | Yes | Yes |
Note:
On OCI, BLX with DPDK is not supported. You can run BLX in a dedicated mode without DPDK support.
On Amazon Linux, BLX with DPDK is supported only with an Elastic Network Adapter (ENA).
Hardware requirements of Linux host
| Category | NetScaler BLX with DPDK support | NetScaler BLX |
|---|---|---|
| Processor | Intel or AMD x86-64 (64-bit) processor | Intel or AMD x86-64 (64-bit) processor |
| Minimum RAM | 2 GB | 2 GB |
|
Drivers
|
Intel ports: igb, ixgbe, and i40e
|
All Linux supported drivers
|
Intel port Virtual Function ports: iavf
|
||
Mellanox ConnectX-5 ports: mlx5_core
|
||
Amazon EC2 Elastic Network Adapter ports: ena
|
||

Note:
- BLX supports a maximum of nine NIC ports (DPDK NIC ports, non-DPDK NIC ports, or a combination of both).
- The Linux host must meet the minimum system requirements for installing DPDK. For more information about the minimum requirements of DPDK, see the Official DPDK Documentation.
Open source packages
The following dependencies are required on the Linux host.
- Auto-installed dependencies
- Manually installed dependencies

Manually installed dependencies
The following dependencies must be installed manually on the Linux host from the standard public repository.
-
For RPM-based Linux systems, install Extra Packages for Enterprise Linux (EPEL) repository
For information about installing the EPEL repository, see EPEL.
-
For Debian based Linux systems running Ubuntu version 18 or later, install
libc6:i386repositoryRun the following command on the Linux shell to install the package:
dpkg --add-architecture i386apt updateapt install libc6:i386
-
For Amazon Linux 2 on AWS, install EPEL repository
Run the following three commands on the Amazon Linux 2 shell to install EPEL repository:
amazon-linux-extras install epel -yyum-config-manager --enable epelyum update
For more information about installing the EPEL repository, see the AWS official documentation.
