Installing the CTERA Edge Filer in an Azure Environment

Installing the CTERA Edge Filer involves creating and configuring a virtual machine and then performing an initial configuration, described in Initial Setup.

The gateway can be installed in a Microsoft Azure environment with the following:

  • Microsoft Azure portal premium account.

  • Azure instance that matches the license:

    License Memory (GB) Maximum Data
    EV16 8 16TB
    EV32 16 32TB
    EV64 32 64TB
    EV128 64 128TB
  • Premium disks: P40 or P50 with maximum throughput of 250MB/s.

Contact CTERA Networks, and request the latest Azure edge filer Image for Azure to be uploaded to your account.

The edge filer image used to create the is obtainable from CTERA support at http://support.ctera.com and needs to be moved to your Azure portal, using Azcopy.exe, available for download from https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10. The zip file contains the azcopy.exe program.

Warning

The CTERA Edge Filer installation must be done using the image and not by cloning an existing CTERA Edge Filer.

To get the image from CTERA support at http://support.ctera.com:

  1. Log in to your Azure portal and access the Storage Accounts service to display the images.

    1. Select a VM that matches your requirements. The size you select should be dependent on the license.

      License Maximum vCPUs Maximum Memory
      EV16 4 8GB
      EV32 8 16GB
      EV64 16 32GB
      EV128 32 64GB

      The gateway software requires less than 1GB SSD storage. CTERA limits the number of data disks for a gateway to 16.

    2. Click Select.

    Note

    Once the virtual machine has been fully configured, CTERA provides a user name and password, but this user name can also be used.

    Public inbound ports – Choose the None option. Inbound and outbound ports will be added later.
    Leave the other values with their defaults.
