QxStor Red Hat Ceph Storage Edition

Optimal Integrated Ceph Solutions at Petabyte Scale

QCT offers a family of servers for different types of scale-out storage clusters, optimized with Red Hat Ceph Storage for different workloads and budgets. The SDS solutions deliver seamless interoperability, capital and operational efficiency, and powerful performance. Delivered in one self-healing, self-managing platform with no failure, QCT QxStor Red Hat Ceph Storage Edition makes businesses focus on improving application availability.

Optimize for Different Workloads

QCT servers are offered in a range of configurations to allow diverse workload optimization – IOPS optimized, throughput-optimized and cost-/capacity-optimized configurations. Ranging from dense, 1U systems to models providing massive storage capacity, servers enable Ceph journaling by providing expansion slots for PCIE SSDs or specially designed spaces for SSDs.

Scale Performance and Capacity Independently

Unlike scale-up storage solutions, QxStor Red Hat Ceph Storage Edition lets organizations scale out to thousands of nodes and scale storage performance and capacity independently, depending on application needs and storage server platform.

Offer Impressive Performance through Engineered Configuration Matrix

QCT and Red Hat architects have conducted extensive Ceph testing on configurations for QCT QuantaGrid D51PH-1ULH and QCT QuantaPlex T21P-4U servers. Testing revealed that QCT servers provide multiple benefits for organizations deploying Ceph clusters, including:


  • Minimized Risk
  • Extensive QCT and Red Hat testing reduces the risk out of deploying scale-out, Ceph-based storage solutions.
  • High Density
  • Cost- or capacity- optimized configurations provide industry-leading density. Innovative QCT server platforms are easy to deploy rapidly at scale.
  • Flexibility
  • For throughput-oriented workloads, both QCT QuantaGrid D51PH-1ULH and QuantaPlex T21P-4U servers with Ceph replicated pools enable organizations to use a range of different cluster sizes.
  • Cost-Effectiveness
  • For object archive workloads, QCT QuantaPlex T21P-4U servers with Ceph erasure-coded pools provide competitively priced storage.
  • Scalability
  • For high-throughput workloads, QCT QuantaPlex T21P-4U servers with Mellanox ConnectX-3 Pro 40 Gigabit Ethernet NICs (network interface controllers) provide scalable throughput and competitive rack-density.
