Data Storage Solution:

• Expertise in both NAS and SAN based storage technology
• NAS: works best for these types of applications:
  File serving
  File sharing
  Users' home directories
  Content archiving
  Metadata directories
  E-mail repositories, such as enterprise .PST files
  GRID computing (using 10 Gigabit Ethernet)
  Peer-to-peer data sharing
  
• SAN: works best for these types of applications:
  Databases
  Server clustering
  Messaging applications
  Backup
  Data replication
  GRID computing
  Data warehousing
  Recovery archives
  Any application that requires low latency and high bandwidth for data movement. These low-latency networks allow large blocks of data to move very fast from computers to storage, with speeds up to 400 megabytes per second
  
• Cross-mirroring data (two systems)
  
• SATA (serial advanced technology attached) - low in cost, high in density, and
  ideally suited for large, sequential data such as backup and GIS image data
  transactions
  
• FC (Fibre Channel) - allows data to be transmitted and received at one gigabit
  per second simultaneously delivering high service levels but at a greater cost.
  SAS (Serial attached SCSI) -
  Data backup and Redundancy RAID
  Redundancy for improved reliability
  RAID (Redundant array of inexpensive disks) functionality
  RAID is a way of storing the same data in different places on multiple hard
  disk.
  Data mirroring or duplication
  An array of multiple disks accessed in parallel will give greater throughput
  than a single disk
  Data striping, for improved performance
  Redundant data on multiple disks provides fault-tolerant
  Redundancy for improved reliability
  RAID Systems Need Tape Backups
