HDS has announced new unified Storage systems called Hitachi Unified Storage or HUS. This systems will replace the aging AMS family. HDS announced 3 models (HUS 110, 130, 150). Please see the specs here and the positioning here (page 3)

Hitachi Data Systems (HDS) has replaced its mid-range AMS storage array with the Hitachi Unified Storage (HUS) array that stores block, file and object data in one box. It is managed by the Hitachi Command Suite which is now a single software management facility for all HDS products.
HDS claims “HUS stores multiple data types with more flexibility and more balanced scalability than any other midrange solution” and it is the “first enterprise-class unified storage solution.”
HUS scales capacity to almost 3PB within a frame, and has so-called dynamic virtual controllers that automatically correct performance problems and provision storage resources quickly. Hitachi Dynamic Provisioning pools and grows file and block storage. Filesystems can be up to 256TB in size with a single namespace.
There are three HUS models: the HUS 110, 130 and 150. As a block-storage platform, they replace the three-model AMS range underneath the enterprise-class VSP.
It includes thin provisioning and page-based automated data tiering, plus five nines (99.999 per cent) data availability. The file tiering is native whereas HDS asserts its main competition uses a third-party product.
HUS, we are told, has integration with the Hitachi Data Discovery Suite for search and the Hitachi Content Platform (HCP) for archive. HDS tells us competing products are not integrated with tiering.
The storage giant adds that provisioning is simplified through virtual LUN ownership. HUS workloads can be dynamically balanced to maintain predictable performance. The array can achieve required performance levels for sequential, random workloads and file access.
HUS apparently scales in capacity, predictable performance, replicated data, block volume size and file system size. The claim is that it is “the fastest midrange storage system available today for block and file data access”.
