Zstor, a Germany-based leading producer of high-performance storage offerings for compute-intensive applications, is announcing its newest flagship storage solution family based on the latest NVMe specification. Zstor’s new NV-Series is developed in conjunction with Mangstor Inc., and uses Ethernet or Infiniband Remote Direct Memory Access (RDMA) networks to take advantage of the low latency benefits of the NVMe standard. This enables flash memory to be deployed centrally for access by many servers in a shared storage environment. Zstor’s NVMe over Fabric solution combines a powerful storage stack with a high-speed, high-efficiency multicore compute platform. This configuration dramatically improves I/O performance and sever storage scalability in high-performance and latency-intensive usage scenarios.
Zstor’s NV-Series utilizes Mangstor NVMe SSDs that feature a 100-core DSP and algorithms that are geared to deliver superior performance via the efficient scheduling and management of individual NAND memory cells. This innovative I/O offload architecture provides the key advantage of running advanced device control logic on a highly efficient multicore DSP, rather than on the host process servers, delivering I/O performance with very consistently low latency to attached application servers.
According to Helmut Kopel, CEO of Zstor, “Customers that use the Zstor NV-Series storage array will benefit from an increase in the number of transactions per second processed, a reduction in time where there are no user actions, and a higher number of completed transactions. Our NV-Series of Fabric array not only delivers four to six times higher performance to servers when compared to other all-flash arrays, but does so at very aggressive acquisition costs.”
Read and write latencies begin at 30/110µs, and are consistently low regardless of being at idle or processing millions of IOPS. The Zstor NV-Series’ impressive mix of low latency and high bandwidth is ideal for supporting a variety of compute-intensive usage scenarios. Zstor’s innovative storage stack optimizes data movement from the RDMA network to the flash storage, and servers have read and write access over RDMA to the array, which results in latencies that are comparable to that in which servers are accessing local PCIe SSDs. The 2U version of the NV-Series attains over 3,000,000 random 4K read IOPS and over 2,250,000 random 4K write IOPS.
Zstor’s use of Mangstor NVMe SSDs includes Mangstor’s popular TITAN software, which tightly integrates the Mangstor NVMe SSDs with a low latency and high-performance RDMA network to provide superior performance, and extremely efficient use of x86 server capabilities. At the 2015 Flash Memory Summit, this combination of innovative technologies earned a Best of Show award in the “Most Innovative Flash Technology” category.
The Zstor NV-Series’ breakthrough performance is ideal for database applications that include OLTP, OLAP, data warehousing and data mining. It is also well-suited for High Performance Computing (HPC) usage scenarios such as financial processing and analysis, oil and gas exploration, online trading, video pre- and post-editing, virtualization, and science-related simulations.
The Zstor NV-Series is available now, with net capacities from 5.4TB up to 16.2TB. Zstor is backing the NV-Series with a 5-year limited hardware warranty.
