Steelhead Valuable Features
The first feature that is valuable is SDR, Scalable Data Referencing. Suppose you have two offices, one based in India and the other one is in the U.S., which is where the data center is. If an engineer is working from India and accessing an application from there, downloading or uploading files or folders over the file server or other applications, SDR will cache the data on the SteelHead device itself. The second time, he won't need to go via the WAN. He will be able to download the file locally. He will feel he is getting LAN-like speed over the WAN.
The second valuable feature is the compression.
The third valuable feature is the TCP optimization. Every time protocols are communicating with each other, every time they establish a connection, three is a three-way handshake. For UDP there is no handshaking because it is connection-less. But TCP does the three-way handshake before delivering any information to the application. The optimization feature caches a particular TCP connection and the next time a user uses that connection he will reach the destination easily.View full review »

A feature we like is data streamlining. Riverbed does packet deduplication, packet compression and uses something like simple data referencing to compress the data. If one gig of traffic is sent to one link, that gig of traffic coming from the packet is only 100 mbps, so the compression of Riverbed is very powerful.
Another is transport streamlining, which includes TCP optimization. The window size of the TCP protocol is achieved in order to transfer more data in the TCP section despite the endpoint. The endpoint transfer was very slow, but it doesn't matter because with Riverbed in the middle, it can handle more quantities of traffic.
For application streamlining, where the HTTP application previously had a lot of traffic, Riverbed recognizes HTTP protocols and it can optimize the process because it can create the HTTP server. Normally, the browser and web server agree and compress the traffic, but if Riverbed is in between, it strips the compression from the browser and Riverbed does its own compressions, which is more powerful, and hence, the application runs faster for the user.
Also, for HTTP, Riverbed does caching so it can store data from all the user traffic. It keeps track of the HTTP data locally. Traveling into the server isn't necessary. They can retrieve the information locally because there is a local Riverbed.

The solution has been very good since the beginning. It is quite reliable.
It is very easy to install the solution.
Technical support has been very good.View full review »
I find the most valuable to be the compression and exchange replication. It is very useful, user friendly, and the documentation manuals are helpful.View full review »
