10-member medical practice needs to ensure patient records are always available. A $50-million manufacturer is
  desperate to find the manufacturing data to prove it met the exacting specifications of an important custom order. A $100-million architectural firm will do almost anything to retrieve an e-mail thread from two years ago to defend itself against a suit by a building owner.
  
    Each of these small to medium businesses (SMBs) needs a flexible and scalable storage system to ensure critical data can be accessed quickly, securely and cost effectively-- even after a natural or manmade disaster destroys its primary storage systems. Five, or even two, years ago, none of these companies would have considered a storage
  area network (SAN), even though SANs have an impressive track record for managing the growth of common data-intensive applications such as Microsoft SQL Server?and Microsoft Exchange with aplomb.
