FlexSDS is a high-performance, software-defined storage platform engineered for high-performance computing (HPC) environments. Running on industry-standard x86 hardware, FlexSDS supports unlimited capacity per node and up to 2 PB per storage pool—delivering flexible, efficient, and massively scalable storage infrastructure tailored for the most demanding workloads.

Optimized for data-intensive HPC applications, FlexSDS enables seamless parallel access to data, extreme I/O concurrency, and cost-efficient scalability. It supports both block and distributed file storage, empowering organizations to accelerate time-to-insight and increase computational throughput without compromise.

Key Features for HPC Workloads

Parallel Distributed File System (DFS)
High-performance, parallel-access DFS designed for HPC-scale concurrency. Supports simultaneous large-scale data access across hundreds or thousands of compute nodes, ideal for simulation, modeling, AI/ML, and scientific research workloads.

Scalable Erasure Coding (EC) Across 128 Nodes
FlexSDS offers large-set erasure coding for enhanced data durability and space efficiency at scale. Supports up to 1024 nodes in a single cluster, enabling reliable, high-availability storage with minimal overhead—even in massive environments.

Extreme I/O Throughput & Low Latency
Kernel-bypass architecture, lock-free data paths, zero-copy memory operations, and CPU cache optimization ensure ultra-low latency and high bandwidth—crucial for HPC and real-time workloads.

Comprehensive Hardware Compatibility
Supports a full range of storage media from HDDs to NVMe SSDs, and networking from standard TCP to high-speed RDMA (RoCE, iWARP, InfiniBand). Fully compatible with All-Flash, HDD, and Hybrid arrays.

Massive I/O Parallelism
Engineered for parallel and high-concurrency I/O operations, FlexSDS ensures optimal utilization of compute, storage, and network resources across the entire cluster.

Flexible Block Storage Architecture
Offers thin-provisioned, log-structured, or raw volumes exported over SAN protocols including iSCSI, iSER, and NVMe-oF. Supports integration with leading hypervisors such as VMware vSphere, Hyper-V, Citrix XenServer, and KVM/QEMU.

High Availability & Auto Recovery
Enables multi-node replication and automated recovery mechanisms to ensure continuous operation and fault tolerance in large distributed environments.

Efficient Asynchronous Replication
Supports both periodic and continuous remote replication to maintain data protection and minimize recovery time objectives (RTO).

Elastic Scalability
Rapid deployment and effortless scale-up or scale-out across compute and storage resources. Dynamic workload balancing adapts to changing demands in real time.

Centralized Management Interface
Simplified management with a single-pane-of-glass interface for monitoring, configuration, and administration.

Optimized for Low TCO
Maximizes resource efficiency while reducing operational complexity and total cost of ownership—making HPC-scale storage more accessible than ever.
