Access Node Requirements for Amazon

Updated

On this page

To provide better throughput for operations, use a compute-optimized instance hosted in Amazon. For more information, see Amazon EC2 Instance Types.

The access node (VSA proxy) must be in the same Amazon account and located in the same region as the source instances.

The access node must meet the following requirements:

  • The access node machine must be one of the following types of machines:

    • Windows Server 2019

    • Windows Server 2016

    • Windows Server 2012 R2

    • For Linux proxy support, configure an access node on a Linux instance using either of the following methods:

      • Deploy an AWS Marketplace AMI to serve as an access node for Amazon.

      • Configure a CentOS 7.4, CentOS 8, RHEL 7.5, or RHEL 8 instance with the required software.

        Note: For CentOS 8, Oracle Linux (OL8.x), or RHEL 8 instances, to install operating system packages that must enable automatic installation of Mono, register the instances with CentOS, Oracle, or Red Hat.

      • Configure an AWS Linux instance that uses a 64-bit Arm processor with the required software.

        For more information, see Linux Access Node Support for Amazon Web Services.

  • Minimum of 100 GB disk space recommended.

  • Minimum of 4 GB RAM required beyond the requirements of the operating system and running applications.

  • The access node machine must be able to connect to ec2.amazonaws.com, or the regional equivalent if the Amazon account is restricted to specific regions. To route communications through an HTTP or HTTPS proxy, provide proxy information in the CommServe Control Panel, on the HTTP Proxy tab of the Internet Options dialog box. To use an HTTPS proxy, you must provide authentication details.

For VSA proxies running on Amazon instances, the following additional requirements apply:

  • Windows Server instances where the Virtual Server Agent is installed must upgrade to the latest paravirtual (PV) driver.

  • EBS optimized, high IOPS volume.

  • If the access node that is used for replication is running on an Amazon instance, the access node must be available in the same user account as the source instances that are being replicated. This requirement does not apply when replicating from source snapshots.

Network Connectivity

The Virtual Server Agent requires Layer 3 network connectivity to the upstream MediaAgent on port 8403. If the MediaAgent and the access node (VSA proxy) are in different accounts or in different Virtual Private Clouds (VPCs), you can configure Amazon VPC peering as described in the AWS article VPC peering basics.
