SteelFusion Edge Overview
This chapter provides an overview of the SteelFusion Edge and the Management Console. The Management Console makes managing your Edge simpler through a web browser interface. This chapter includes these sections:
This chapter assumes you have installed and configured the Edge. For details, see the SteelFusion Edge Installation and Configuration Guide.
This chapter also assumes you are familiar with the various deployment options available to you. For details, see the SteelFusion Design Guide.
Introducing SteelFusion Edge
SteelFusion is a converged infrastructure solution, encompassing all branch services such as server, storage, networking, and WAN optimization. SteelFusion is a dual-ended system that comprises two logical components: SteelFusion Edge and SteelFusion Core.
SteelFusion Core is a physical or virtual appliance in the data center that mounts all NFS exports that need to be made available to applications and servers at a remote location from the back-end storage array. SteelFusion Core appliances communicate across the WAN with the SteelFusion Edge appliances at the branch.
SteelFusion Edge is a physical appliance that is located at the branch. The Edge provides a high performance, virtualized environment that hosts the branch application servers. The Edge also provides network and optimization (depending on your order).
SteelFusion delivers local user performance while enabling data centralization, instant recovery, and lower total operating costs. Unlike traditional converged infrastructures, SteelFusion enables stateless branch services. You can access applications that run locally in your branch while the primary data is centralized in your data center. Decoupling computation from its underlying storage allows your applications to run in a stateless mode, which reduces your branch footprint and centralizes management of your branch services.

SteelFusion terminology
These terms will help you understand SteelFusion and its features:
• Hypervisor - The bare-metal VMware software that allows you to run and manage virtual machines so that you can reduce the amount of hardware in your branch and data center.
• Virtual Services Platform (VSP) - VSP is software that runs as a part of the RiOS networking and optimization software. VSP manages, communicates with, and reports on the hypervisor.
• Virtualization platform - The virtualization platform is made up of the hypervisor and VSP.
The hypervisor uses ESXi as the virtualization platform. The hypervisor is included in the Edge functionality and does not require a separate download. You set up the hypervisor through the Edge Management Console. You set up and configure virtual machines through the VMware vSphere Client or vCenter.
You can install and use the VMware vSphere Client or use the vSphere Web Client to monitor and manage a single instance of the ESXi server. You can download the vSphere applications from the VMware website, or you can download the vSphere Client from the hypervisor host.
Benefits of SteelFusion Edge
SteelFusion Edge offers these benefits:
• A VMware-based virtualization platform with the benefits of the most commonly deployed and advanced virtualization tool set.
• When teamed with SteelFusion Core, it provides the ability to present NFS version 3 storage exports projected from the data center as local NFS version 3 exports to applications and servers on the local branch network.
• SteelFusion Edge does not place any limitations on the number of virtual machines on a single hypervisor, as long as there are enough resources available and you are within the maximum number supported by ESXi.
• Improved security.
• Fast recovery capabilities and instant provisioning at the branch.
• A simplified hypervisor configuration through an installer in the Management Console, as well as access by using the standard VMware administration tools, such as vSphere Client and vCenter.
SteelFusion Edge architecture
The Edge hardware platform contains two distinct computing nodes within a single chassis:
• RiOS node - Provides networking, WAN optimization, direct attached storage, and VSP functionality.
• Hypervisor node - Provides hypervisor-based hardware resources and software virtualization.
The two physical node design provides true hardware resource separation and isolation. The RiOS node handles traffic to and from SteelFusion Core as well as any application traffic that may be subject to WAN optimization. It also hosts an NFS fileserver. The hypervisor node hosts an instance of VMware vSphere for running one or more virtual machines. The vSphere datastore is mounted as a fileshare exported from the NFS fileserver located in the RiOS node.
You manage the hypervisor node of the Edge using VMware tools, such as the vSphere Client and vCenter.

For details on the RiOS and hypervisor nodes, see the SteelFusion Edge Installation and Configuration Guide and the SteelFusion Edge Hardware and Maintenance Guide.
Software dependencies and compatibility
This section provides information about software dependencies and compatibility. It includes these topics:
Software dependencies
This table summarizes the software requirements for the SteelFusion Edge.
Component | Software requirements |
SteelHead, SteelHead Management Console | RiOS 9.10 Any computer that supports a web browser with a color image display. The Management Console has been tested with Mozilla Firefox Extended Support Release 38.0, Google Chrome, and Microsoft Internet Explorer 11.0. JavaScript and cookies must be enabled in your web browser. |
BlockStream, SteelFusion Core Management Console | Version 5.1 or later Software versions for SteelFusion Core and SteelFusion Edge cannot be more than two major releases apart. For example, 4.0 and 4.2 are compatible, but 4.0 and 4.4 are not compatible. |
VMware vSphere Hypervisor | ESXi 6.5 EP 20 (shipped with Edge appliance) Optionally, you can upgrade the ESXi version to 6.7 Patch 15. This optional version require you to download the image from the Riverbed Support site at https://support.riverbed.com. The Edge appliance ships with a Riverbed-specific VMware vSphere Hypervisor license. This license enables basic hypervisor functions such as monitoring and management of a single instance of the ESXi server. |
VMware vCenter Server | vCenter Server provides a centralized platform for managing your VMware vSphere environments. The vCenter Server requires a paid license that can be purchased from a VMware reseller. |
We strongly recommend that you read the
SteelFusion Interoperability Matrix on the Riverbed Community site at
https://community.riverbed.com/helpcenter/s/article/DOC-4204 or on the Riverbed Support site at
https://support.riverbed.com.
For information on compatibility between RiOS, Edge, Core, and vSphere releases, see the Knowledge Base article
RiOS, SteelFusion Edge, SteelFusion Core and vSphere Release Matrix -

SCC compatibility
To manage SteelFusion Edge appliances, you need to use a compatible version of SCC. For details about SCC compatibility across versions, see the SteelCentral Controller for SteelHead Installation Guide.
As a result of updating the version of Secure Shell (SSH), earlier versions of SCC cannot connect to newer software on managed appliances. Upgrade the SCC before upgrading
Edge appliances to avoid disconnections. For more details, go to
Knowledge Base article S27759.
