CIB448 Cluster-in-a-Box
Cost-effective, high available and high capacity Storage Server
Zstor CIB448 Front 45 Open   

The Zstor CIB448 Storage Server series is based on INTEL® Skylake 2U height unit platforms with two independent computer nodes with CiB (cluster-in-a-box) capabilities, enabling transparent failover between both nodes. CIB448 systems offer excellent reliability and high packing density, making them the ideal choice for building Software-Defined- Storage solutions. As a fail-safe CiB solution with RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), the Zstor CIB448 Cluster-in-a-Box Server offers one of the best software-defined storage solution based on Microsoft Windows 2012R2 / 2016 / 2019 Storage Spaces. It is also the ideal HA Solution for ZFS solutions like ZFS on Linux, FreeNAS, OmniOS, OpenIndiana, Solaris with napp-it.

Highest Performance
The second generation of the scalable Intel® Xeon® processor series offers leading, workload-optimized performance features with a perfectly tuned performance base. Platform innovations and hardware-enhanced virtualization of the computing, network and storage infrastructure with support for a new class of innovative storage that enables cost-effective, flexible and scalable multi-cloud environments to deliver consistent, high-quality business-to-business and business-to-consumer performance.

Flexible network configuration including Remote Direct Memory Access (RDMA)
With a large selection of different NICs (Network Interface Controllers) in OCP or PCIe format from 1G/10G Ethernet (RJ45) to 10/25/40/50/100G Ethernet (SFP+) a high flexibility and performance of the network is achieved. Optional Mellanox NICs with RDMA capabilities provide a technology to bypass the network path of the operating system and allow direct access to the memory of the other storage server with less CPU load, lower latency and higher throughput.

Applications in continous and reliable operation
The use of power supply redundancy and hot-swappable node design allows a more reliable and fail-safe operation. The hot-swappable modules simplify the service and maintenance of the server in the data center.
