Hitachi Adaptable Modular Storage (AMS)

ViON presents the Hitachi Adaptable Modular Storage (AMS) 2000 family, a flexible storage platform designed to help organizations achieve key business benefits, such as meeting service level agreements (SLAs), attaining cost effective performance and ensuring non-disruptive operations, while realizing better administrative efficiencies and investment protection.

The AMS 2000 family is made up of the AMS 2100, AMS 2300, AMS 2500 and AMS 2500DC models. All models support multiple RAID configurations, fibre channel and iSCSI host interfaces, and the ability to intermix SAS and SATA disk drives on the same tray. All three models are well suited to serve as: inexpensive lower tier data storage that does not compromise the highest levels of reliability and centralized management; virtual tape or tape displacement solutions; and remote office storage or archive solutions.

The AMS 2000 family’s architecture includes a dynamic load balancing controller that provides integrated, automated hardware-based front-to-back-end I/O load balancing. This ensures that I/O traffic from hosts to disk drives is dynamically managed, balanced and shared equally across both controllers. The architecture also includes a SAS backend. The SAS interface is a full duplex, point-to-point architecture with up to 9600 MB/sec of total system bandwidth and up to 32 links available for concurrent I/O activity – more total backend bandwidth than any other midrange product on the market.

flexible storage platform
SATA disk drives are compatible with SAS connectors to facilitate an intermix of SAS and SATA drives on the same tray, providing a new level of flexibility in meeting tiered storage requirements. This flexibility can lower the total costs of ownership since it is no longer necessary to purchase separate trays for SAS and SATA drives.

The AMS 2000 family also supports virtualized capacity via Dynamic Provisioning. Hitachi’s Dynamic Provisioning offering eliminates application service interruptions, reduces costs and simplifies administration. Less capacity can be purchased up front and expansions can be paid for in line with actual business usage. This also reduces operational costs (electricity and floor space) since unused disks are no longer left spinning. Hitachi Dynamic Provisioning software provides performance improvements through proprietary automatic optimized wide striping of data across all available disks.
