Just a Bunch of NVMe Flash - JBOF – is the logical next step in requirements requested for datacenter environments looking for cost-efficient, high-performance, and flexible to use storage. Zstor, an innovative company offering professional storage and server systems for datacenter, launches the new flagship Zstor NV24P JBOF NVMe Flash system with storage capacity of up to 184 TB exclusively on WHD show at Europapark rust. Based on a PCIe architecture directly connected between servers and JBOF a central Zstor NV24P JBOF offers nearly identical performance characteristics in terms of IOPS load and latency versus local NVMe SSDs. Through combining NVMe Storage into a centralized Zstor NV24P JBOF the operating costs will be significantly reduced and the flexibility in connection of NVMe storage to dedicated servers will be increased.

JBOF - just a bunch of NVMe Flash – comes slightly inline from well-known JBOD – just a bunch of disk -. The idea to centralize Flash memory in direct attached storage (DAS) connectivity is perfect realized when using Zstor NV24P JBOF together high performance PCIe host bus adapters. The PCIe system interfaces give the full bandwidth of server performance directly to the attached JBOF without using any switch. As known from the JBOD technology also the JBOF system gives the benefits in cost reduction while keeping the performance features available.
"NVMe SSDs almost used in any server farm offers the needed performance. With the Zstor NV24P JBOF as centralized Flash system it offers beside a flexible use also a significant cost reduction by keeping the needed performance levels", says Helmut Kopel, Managing Director of Zstor GmbH. „The strategy of combining expensive high-performance storage devices in a centralized system for cost reduction will become a clear standard in datacenter very soon."
The IT infrastructure in which the Zstor NV24P JBOF will be used, is based on the consistent implementation of local requirements for PCIe-based high-performance storage into a centralised PCIe-based system with NVMe SSDs. Order to meet the requirements in high IOPS-load and low latency up to eight servers can be connected via NVMe PCI-e Gen3 host bus adapters to the Zstor NV24P JBOF Flash storage. The PCIe interfaces connect servers directly to the JBOF without any additional switches. The Zstor NV24P itself offers flexible NVMe storage directly to attached servers via physical zoning maps. This Zstor NV24P JBOF is supported by all operating systems without additional drivers and can be used also cross-platforms.
The Zstor NV24P JBOF, equipped with a three years system warranty is available from now as well as the necessary NVME PCIe host bus adapter Zstor P300 series. Capacity up to 24x 7.68TB = 184TB can be realized in one Zstor NV24P JBOF. The product prices are subject to the necessary capacity and the connection to the relevant server.
