Read Latency

The NVMe Gen 5 Controller IP implements NVMe 2.0 over a PCIe Gen 5 x4 host interface, unlocking 16 GB/s sequential read bandwidth and 2M random 4K IOPS. Designed for enterprise U.2 / E1.S / EDSFF form-factor SSDs and AIC cards, it handles the complete NVMe command layer including submission queue management, completion queue DMA, PRPs, SGLs, and namespace management.

Support for Zoned Namespace (ZNS), Key-Value (KV), and Computational Storage (CSx) command sets — all defined in NVMe 2.0 — enables emerging storage architectures that reduce write amplification and improve QoS in cloud-native deployments. OCP NVMe Cloud Specification v2.0 compliance ensures compatibility with hyperscale procurement requirements.

Features

Enterprise-Grade NVMe Feature Set

NVMe 2.0 Command Set

Full NVMe 2.0 I/O and Admin command sets with Read, Write, Compare, Verify, Flush, Dataset Management, Copy, and all mandatory Admin commands.

65535 I/O Queues

Up to 65535 submission and completion queue pairs supporting multi-tenant and multi-core host environments with per-queue priority and interrupt coalescing.

Zoned Namespace (ZNS)

NVMe ZNS command set for zone-based sequential-write flash management, reducing host DRAM requirements and eliminating device-side write amplification.

Key-Value (KV) Storage

NVMe 2.0 Key-Value command set enabling direct object store operations (Store, Retrieve, Delete, List) without a traditional block-layer translation stack.

End-to-End Data Protection

T10 DIF/DIX PI Types 1/2/3 for end-to-end data integrity protection from host to NAND, with guard tag generation, checking, and error reporting.

SR-IOV & Multi-function

PCIe SR-IOV with up to 256 Virtual Functions for NVMe namespace sharing across virtualised datacenter environments (VMware, KVM, Hyper-V).

Encryption (AES-256)

Inline AES-256-XTS hardware encryption engine with per-namespace key management and TCG Opal 2.0 / Ruby/Pyrite compliance for self-encrypting drives.

Telemetry & SMART

Full NVMe SMART/Health log, Error log, Telemetry Host-Initiated and Controller-Initiated logs, and OCP SMART extended log for datacenter fleet management.

Power Loss Protection

PLP detection input with automated flush-to-NAND on power loss, capacitor-hold sequencing, and FTL journal replay for guaranteed data durability.
