Eight reasons to go for SAS switching

An alternative solution to the mounting data deluge

CIOs and data centre operators  will need to reassess their current storage infrastructure and consider technologies that can address  current data storage challenges including data growth and the associated costs.
The general trend has been to increasingly deploy networked storage, whether Network Attached Storage (NAS) or block SAN, however, there is still a large install base of direct attached external and internal storage.  DAS can, however, have scalability issues. In the Direct Access Storage (DAS) environment when all server ports are in use, new storage can only be added by adding new servers, which can be extremely expensive and can create storage islands.

Here are some reasons why Serial Attached SCSI (SAS) switching can solve these problems
