System overview
data to an applicable storage "tier" without requiring users and applications
to be pointed to the new location is a key feature of the Hitachi File System.
This ability to extend the Hitachi File System to external devices, including
other Hitachi products (such as HCP), private or public cloud, and even third
party, or foreign, file systems accessible from the servers via NFSv3. Such
data migration mechanisms also allow for repurposing of existing storage
devices as external storage tiers, lowering total costs and offering easier
platform transition.
Effective data reduction
The Hitachi File System can reduce storage requirements by various
mechanisms, thus making storage more cost effective. The Hitachi File
System can de-duplicate primary data with minimal performance impact.
In addition, it can move data that is not actively used to the private or public
cloud, thus greatly reducing the amount of data that is retained in
expensive storage. Using HNAS in conjunction with Hitachi Content
Platform (HCP) or Hitachi Capacity Optimizer (HCO) makes it possible to
"backup less", which results in significant saving in operational costs.
