DirectAccess, Microsoft's pairing of Windows 7 and Windows Server 2008 R2 for connect-anywhere access, is possibly the best thing Redmond has produced in a long time. Unfortunately for many, it just may be about five years too early.
Now in its fifth release, Riverbed Technologies RiOS WAN acceleration operating system adds some new features to an already impressive list of services and also includes better centralized management through the Central Management Console (CMC). New to RiOS 5 is native Exchange 2007 support, easier HTTPS configuration, and a better QoS engine. Overall WAN performance is on par or better than in previous releases, with CIFS (common Internet file system) traffic showing a modest increase and FTP cold pass improving significantly.
