JBOF - Just A Bunch Of NVMe Flash -

ExtENT YOUR ServerS with low Latency and HIGH Capacity STORAGe

Zstor NV24P JBOF product allows 24 NVMe 2,5“ PCI-E devices joined together in one shelf, that can connect to multiple hosts or servers. A group of shelves can build a NVMe farm for Hyperscale server farms. The JBOF head need one or more NVMe Host Bus Adapters which is connected through externals cables to the JBOF.

PCI-e Gen 3 Connection end to end CPU to NVMe – NVMe storage read and write access over RDMA networks provides servers with data at nearly identical latencies as if they were accessing local PCIe SSDs; increasing application performance and providing over 3.0 M random 4K read and 2.25 M 4KB write IOPS .

Surprise Hot-removal NVMe PCI-e – Backplane design supports hot-removal and surprise hot-add of NVMe PCI-e devices without causing operating system hangs or crashes. The NVMe JBOF behave like SAS JBOD when drives are replaced.

Multiple head nodes per NVMe devices – Expand infrastructure one node at a time to reduce overprovisioning server Flash SSDs. Independently scale server and storage resources to match workload demands and improve efficiency. Easily scales from 10s to 100s of TB Flash deployments.
