NVMe is the storage protocol purpose‑built for solid‑state drives (SSDs) connected via PCI Express (PCIe). It delivers ultra‑low latency in the tens of microseconds and sustained throughput in gigabytes per second. By leveraging PCIe switch technology, organizations can scale NVMe storage beyond native CPU lane limitations—adding more SSDs per host with minimal overhead.
ATTO and DapuStor, leaders in PCIe switch and enterprise SSD innovation, have partnered to deliver a high‑performance NVMe solution that boosts efficiency, scalability, and reliability across demanding IT environments.
Benefits of the Joint Solution
- Expanded PCIe Connectivity: Scale NVMe storage beyond CPU lane limits with integrated PCIe switching, connecting more SSDs per host while maintaining bandwidth and low latency.
- Optimized Throughput: Aggregate lanes and balance traffic dynamically across NVMe devices, eliminating oversubscription and delivering multi‑drive scaling without latency penalties.
- Seamless Integration: Appears as a standard NVMe device to the host OS—no proprietary drivers required. Compatible with industry‑standard RAID implementations and existing PCIe/NVMe frameworks.
- Intelligent Host & Target Management: FPGA logic orchestrates link initialization, path management, and error recovery independently of CPU resources. Enables multi‑host sharing, drive pooling, and adaptive performance tuning.
- Infrastructure & Power Efficiency: Consolidates NVMe connectivity into a single adapter, reducing reliance on additional CPUs and memory channels. Cuts rack‑level power and cooling requirements for improved density and energy efficiency.
Test Results
A system with one ATTO ExpressNVM S48F NVMe Switch Adapter and four DapuStor PCIe Gen4 R5101 3.84TB SSDs was tested for compatibility and performance.
Metric | Single Drive | 4 Drives Combined | Ratio |
Sequential Read | 6.6 GB/s | 26.3 GB/s | 4x |
Sequential Write | 5.4 GB/s | 21.5 GB/s | 4x |
Random Read | 1570 KIOPS | 3719 KIOPS | 2.4x |
Random Write | 247 KIOPS | 991 KIOPS | 4x |
These results demonstrate the joint solution’s ability to connect and manage multiple NVMe SSDs with minimal overhead, delivering near‑linear performance scaling.
