Storage server design

• Keeping in mind the storage space, access speed,
  ease of administration, budget, recoverability
  and security, storage servers are designed.
  Design sophistication is further increased by the
  constant changing environment with addition of
  new hardware and technology replacing the old
  ones, while maintaining the same compatibility
  and accessibility. Vendors employ the queuing
  theory model to manage peak loads, throughput and
  response time. Servers may also incorporate
  dynamic load balancing system scheme for request
  distribution across the connected hardware.

Storage server types

• There are two types of storage servers dedicated
  and non-dedicated servers. A dedicated server is
  designed for exclusive usage as a file server
  with workstations specific for reading and
  writing files and databases.
• Storage of data files is achieved by forming a
  disk array. The technology is developed to
  operate multiple disk drives together as a unit.
  A disk array has a cache (faster than a magnetic
  disk) as well as advanced storage visualization
  and RAID. The type of disk array used is
  dependent on the storage network.

Security

• File servers often integrate some form of system
  security to limit file access to specific users
  or groups. In large organizations security is
  handled by directory services like openLDAP,
  Microsofts Active Directory or Novells
  eDirectory. The servers are designed to work in a
  hierarchical computing environment wherein users,
  applications, files and computers are treated as
  distinct but related entities on a network which
  grants access based on groups or users
  credentials. For small organizations
  authentication takes place directly at the
  server. But, for larger organizations, directory
  services include many file servers, potentially
  hundreds.
