=========================
The vFXT platform
=========================

The |avere| Virtual FXT Edge Filer (|vFXT|) leverages the scalability of cloud computing to make your data accessible when and where it's needed - even for data that's stored in your own hardware storage environment. 

Each |vfxt| edge filer node is a virtual machine that runs |os| software. |vnodes| can
use multiple types of storage media including RAM, SSD, and magnetic media. 

Three or more nodes make up a |vfxt| cluster.

In the |aws-first| environment, the |vnodes| are virtual machines created within the |ec2-first| using the |vfxt| |ami-first|.

vFXT instance types
====================

An |ec2| *instance* is a virtual machine. |vnodes| are Amazon |EC2| virtual machines with the |Avere| |vFXT| |AMI|.

|vnodes| in |aws| can be created from these supported instance types:

.. Note:: 
   
   * r3 instances are not available in all regions (examples include eu-west-2 and ca-central-1). Contact |support| if this limitation applies to you.
   * Disk cache per node is configurable and can range from 1000GB to 8000GB.
