Dot Hill Launches New Lustre-friendly AssuredSAN Array

By Pedro Hernandez

Dot Hill, a Longmont, Colo.-based data storage systems provider for high performance computing (HPC) environments, today unveiled a new hybrid flash array, dubbed Ultra56 AssuredSAN, during the SC14 supercomputing conference in New Orleans.

Providing up to 1.34 petabytes (PB) of capacity, the array conforms to the U.S. government military standard (MIL-STD) for IT and Network Equipment-Building System (NEBS) Level 3 requirements for telecommunications providers. Dot Hill's dual-active 4004 controllers help the systems achieve 6,400 megabytes (MB) per second of sustained read performance.

Large block write performance is rated at up to 5,300 MB per second. Small block random reads can hit 100,000 input/output operations (IOPS) per second, from either solid-state drives (SSDs) or traditional hard disk drives (HDDs).

In company remarks, Enterprise Strategy Group vice president Brian Garrett said Dot Hill's latest arrays are arriving just in time for the next-generation of enterprise storage workloads, particularly in the service provider space. "The super-sized capacity of the Ultra56 hardware platform, combined with the simply smart intelligence of RealStor 2.0 software, is ideally suited to ride the next wave of data-intensive workloads including cloud, big data, and the internet of things," he stated.

The new Ultra56 AssuredSAN 4004, along with its predecessor, the Ultra48, also form the basis of a joint Lustre file serving solution announced at SC14 from Intel, Mellanox, and of course, Dot Hill. Lustre is an open-source distributed parallel file system that can handle PBs of capacity and enables HPC-scale IT organizations to achieve data throughput rates of above 100 gigabytes (GB) per second.

Intel is lending its Enterprise Edition for Lustre storage software, which establishes a unified, simple to manage namespace, according to the chip-making giant. Meallanox's InfiniBand hardware, which employs remote direct memory access (RDMA) protocols, slashes data transfer latencies by 90 percent and CPU resource utilization by up to 96 percent.

Taken altogether, the solution can provide up to 576 TB of raw capacity and deliver data throughput rates of up to 56 gigabits per second to each compute node. "More than a terabyte per second (TB/s) of aggregate I/O throughput is possible with a properly sized configuration," claimed the companies in a statement.

Dot Hill Ultra56 arrays are scheduled to begin shipping in January. Prices start at $70,000 for a 336-terabyte, 4U system.
