Hitachi Data Systems (HDS) recently launched a new storage array and updated its HiCommand management software to bring the multi-protocol support and data migration features of its high-end TagmaStore array down to midrange customers.

HDS announced the TagmaStore Adaptable Modular Storage model AMS1000, the successor to its Thunder 9585V array, and the release of the HiCommand Suite Version 5.0 management package with a new approach toward the management and monitoring of multi-path data connections and data availability.

The AMS1000 joins the AMS200 and AMS500 in Hitachi’s midrange lineup and, like its smaller brethren, features Logical Cache Partitioning and Virtual Storage Ports with secure Host Storage Domains.

The “speeds and feeds” are more than double those of the Thunder 9585V. The AMS1000 features 13GBps of cached bandwidth, 4Gbps Fibre Channel connectivity, support for 4,096 LUNs, and 16GB of cache.

One of the keys to the AMS1000 is its embedded multi-protocol support for iSCSI, NAS, and Fibre Channel.

“The AMS1000 lets users consolidate multiple storage platforms on to a single rack,” says Kevin Sampson, HDS’s director of product marketing. A base model of the AMS1000 costs approximately $80,000, but pricing is configuration-dependent.

Another key feature of the AMS1000, according to Sampson, is the Cache Partition Manager, which lets users partition the system cache to match the performance requirements of up to 32 specific applications and prevents less-critical applications from hogging cache.

The AMS1000 also provides multiple tiers of storage within a single system. Users can mix Fibre Channel drives and 250GB, 400GB or 500GB Serial ATA (SATA) drives to create “in-the-box” tiered storage.

The array can also serve as an externally attached tiered or archiving system in a virtualized environment managed by Hitachi’s TagmaStore Universal Storage Platform (USP) or Network Storage Controller using the company’s Universal Volume Manager software.

Version 5.0 of the HiCommand management software includes several new features, such as the Global Link Availability Manager software, which lets users manage and monitor multi-path data connections between hosts and arrays from a single console. Sampson claims that, with this ability, storage administrators can manage a “nearly unlimited” number of separate instances of HiCommand Dynamic Link Manager, Hitachi’s multi-pathing software.

HDS also gave HiCommand a facelift with a new graphical user interface and upgrades to HiCommand Tiered Storage Manager, which analyzes the performance of data migration processes. Tiered Storage Manager Version 5.0 monitors average and maximum array group usage and can relocate an application to fit a change in performance requirements.

The AMS1000 is available now from HDS and its resellers, but the new version of HiCommand won’t hit the streets until later this year.
