Speedy Citrix XenApp and XenDesktop and secure Windows SMB
Also new in Steelhead Mobile 3.1 is native support for Citrix XenApp and XenDesktop traffic. For both Citrix terminal services and virtual desktop infrastructure (VDI) farms, Mobile now helps improve client response time over the WAN and reduce overall bandwidth needs. Mobile also automatically provides QoS for all Citrix traffic, resulting in more consistent and reduced response times. Configuration is limited to choosing the port for your XenApp traffic; there isn't anything else to worry about.
As noted earlier, Steelhead Mobile 3.1 now runs on Mac OS X, and it works like a champ. Along with speeding up WAN connections for the Mac itself, Mobile extends its optimization and acceleration benefits to hosted guest operating systems running on virtualization layers such as VMware Fusion and Parallels Desktop. This means that any virtual machine hosted by the Mac will get the Steelhead treatment and take part in better overall WAN performance. The same goes for virtualization on Windows, for that matter. As long as Steelhead Mobile fits into the computer's network stack -- Mac or Windows -- it can optimize any traffic that passes through it.
By default, Windows Server 2008 domain controllers have SMB signing enabled to encrypt Server Message Block (Windows network protocol) packets as they move between client and server. By encrypting the packets, SMB signing provides a means of authenticating the end-to-end traffic, preventing man-in-the-middle attacks. With the version 3.1 release, Steelhead Mobile can handle these packets by participating in the Active Directory domain. Now Mobile is able to optimize any CIFS traffic it sees, not just unencrypted traffic. Finally, Mobile can now optimize encrypted MAPI traffic between clients and Microsoft Exchange 2007 and Exchange 2010 servers, too.
Riverbed Steelhead Mobile 3.1 plugs important gaps left open from previous releases. Performance keeps pace with its hardware-based cousin and the feature set is maturing nicely, with better SSL support, Citrix optimizations, and support for Windows SMB signing and encrypted MAPI. The Mac OS X client is the icing on the cake -- and best of all, it just works.
