Silver Peak Offers Free Fully-Functional WAN Optimization Virtual Appliance with RDP (and ICA) Support

Silver Peak Systems today introduced the Silver Peak VX-Xpress™ (VX-X), a free and fully-functional virtual appliance for optimizing site-to-site applications over the WAN. Free? Really? Wait… there must be a catch…

Well there is a small catch. It only is for 1 site-to-site link with a Max of 4 Mbps and 8,000 but that is enough for use Remote Display folks because, yes, it supports RDP, ICA and Sunray (?). Check it out:

The new Silver Peak VX-Xpress appliance is based on the Silver Peak Virtual Acceleration Open Architecture (VXOA) that powers the entire portfolio of NX, VX, and VRX products.  Silver Peak offers the industry’s widest range of physical and virtual appliances, ranging from Megabits-per-second (Mbps) to multi-Gigabits-per-second (Gbps) in WAN capacity, with hundreds-of-thousands of simultaneous sessions in a single appliance.  The VX-Xpress is an entry-level solution within the VX product family, and is perfect for organizations just getting started with WAN optimization or those requiring a quick and easy way to optimize the smallest branch or remote offices. The product is free, easy-to-install, and leverages all of Silver Peak’s award-winning network optimization techniques to overcome common bandwidth, latency, and network quality challenges.

Optimize All IP Applications
The Silver Peak VX-Xpress supports 4 Mbps of WAN bandwidth with 8,000 simultaneous sessions, making it ideal for smaller branch and remote offices.  Based on Silver Peak’s VXOA, the VX-Xpress virtual appliance is application, protocol, and software version agnostic, allowing customers to optimize any and all enterprise traffic, including:

  • Backup and recovery applications such as asynchronous backup/replication tools from EMC, HDS, Dell, NetApp, HP, IBM, and other leading vendors.
  • TCP applications, such as Microsoft Windows file sharing, Microsoft Exchange, Microsoft SharePoint, Lotus Notes/Domino, Siebel, SAP, and Oracle.
  • Interactive applications, such as Virtual Desktop Infrastructures (VDI), Citrix XenApp, Sunray, and Remote Desktop Protocol (RDP)
  • Non TCP and real-time applications, like voice-over-IP (VoIP), video conferencing, video streaming, and other unified communications.

Silver Peak VXOA powers the entire family of Silver Peak WAN optimization appliances.  With Silver Peak VXOA, customers can deploy high-capacity, data center class WAN optimization on a wide variety of industry standard hardware platforms and hypervisors.  Customers benefit from unique features that include Network Acceleration to overcome WAN latency, Network Integrity to correct packet delivery issues and intelligently allocate WAN resources, and Network Memory™ to maximize WAN bandwidth utilization.  The result is up to 10x cost savings that can come from decommissioning existing private-line connections and avoiding investments in larger-capacity WANs and bandwidth upgrades.

  1. In addition to hardware solutions, there are also lower-cost software solutions for WAN optimization. Ericom Blaze is a software based RDP Accelerator which can work standalone and also in conjunction with WAN Accelerators and add a lot of value to the network.

    Ericom Blaze has three main advantages over general purpose hardware-based WAN accelerators: performance, security and price.

    Ericom Blaze provides better performance for RDP because it was custom designed for it – Blaze introspects the RDP protocol and applies dedicated optimizations. For example, Ericom Blaze identifies images transmitted inside RDP and applies dedicated image compression algorithms to them, and in addition applies bulk compression to the entire RDP data stream. General purpose WAN accelerators only apply generic optimizations such as bulk compression and caching.

    Blaze takes care of the RDP choppiness while network appliances do not. If you display a movie frame with Blaze, it will display it as a single frame, providing native PC-like presentation, while network appliances will just compress the traffic and the Microsoft RDP client will still display a choppy frame (the frame will display in tiles).

    Ericom Blaze provides better security for RDP than general purpose WAN accelerators because these hardware solutions require RDP’s own encryption to be disabled so that they can compress and cache it. As a result, the communication from the RDP host to the server-side hardware appliance, and from the client-side hardware appliance to the RDP client is not secure. Only the communication between server-side appliance and the client-side appliance is encrypted.

    Ericom Blaze is installed directly on the RDP host and RDP client, and provides end-to-end encryption for complete security. Also, Ericom Blaze can work with both encrypted and unencrypted RDP.

    Ericom Blaze is less expensive than hardware-based WAN accelerators because it is a software-only solution, and does not require specialized hardware.

    To top it off, Ericom Blaze is very easy to deploy and install, and usually does not require any configuration. In most cases, Ericom Blaze can be downloaded, installed and ready for use within minutes.
