Data Storage

What type of Digital Data Storage does a company require?  Depending on the customer, type of data and application – – – Direct Attach Storage (DAS), Network Attach Storage (NAS), Storage Area Network (SAN) and Cloud Storage.

Direct Attach Storage (DAS) is computer storage that is connected to one computer.  For an individual computer user, the hard drive is the usual form of a direct-attached disk drive or array.

Network Attached Storage (NAS) is a type of dedicated file storage device (unstructured data) that provides local-area network nodes with file-based shared storage through an Ethernet connection.  An important benefit of NAS is its ability to provide multiple clients on the network with access to the same files.

A Storage Area Network (SAN) is a secure network which provides access to block level data storage. SANs are primarily used to enhance storage devices, such as disk arrays & tape libraries, accessible to multiple servers so that the devices appear to the operating system as locally attached devices thru Host Bus Adapters (HBAs) either SAS or Fibre connected.

Cloud Storage:  Cloud Storage is a service model in which data is maintained, managed, backed up remotely and made available to users over a network (typically the Internet) owned and managed by a hosting company.

RAID: Redundant Array of Independent Disks) is a data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy and/or performance improvement. (originally redundant array of inexpensive disks).  RAID configurations employ techniques of striping, mirroring or parity.
