Here’s a look at how a SAS simulator developed by University of New Hampshire’s InterOperability Laboratory can scale enterprise storage area networks in the age of big data.
Serial attached SCSI (SAS) currently uses an expander-based networking architecture. The expander acts as a pure port extender with no switching backplane involved, meaning there is minimal flow control and processing taking place. This architecture is severely limited for enterprises requiring larger storage area networks. In fact, once the number of connections starts to increase from tens and hundreds to thousands of connections, the entire network performance begins to decline. Read More
