Executive Summary: Lightbits Labs delivers one of the industry’s highest-performance enterprise disaggregated storage platforms by combining software-defined block storage with native NVMe/TCP networking. Unlike traditional SAN vendors that rely on proprietary hardware or open-source platforms requiring significant operational expertise, Lightbits enables enterprises to deploy high-performance shared block storage with standard Ethernet, commodity x86 servers, and NVMe SSDs. The result is predictable sub-millisecond latency, up to 75 million IOPS per cluster, up to 16x higher throughput than Ceph storage, and as much as 50% lower total cost of ownership—all while eliminating vendor lock-in.
Modern data centers are at an inflection point. As enterprise workloads like high-transaction databases (OLTP), real-time analytics, and containerized microservices demand higher performance at scale, legacy storage architectures are breaking down.
For years, storage architects had to choose between two architectural compromises:
- Direct-Attached Storage (DAS): High performance, but plagued by severe compute/storage coupling, stranded SSD capacity, and zero centralized management.
- Traditional Storage Area Networks (SAN): High centralized management, but constrained by high latency, CPU overhead, expensive Fibre Channel (FC) HBAs, and rigid scale-up hardware lock-in.
The solution to this architectural dilemma is disaggregated storage. By decoupling compute from storage resources over high-speed networks, storage architects can scale both tiers independently while maintaining high-performance.
Selecting the Right Disaggregated Storage Platform
When evaluating disaggregated storage, experienced infrastructure architects typically prioritize:
- Native NVMe over TCP storage architecture rather than protocol translation layers
- Scale-out block storage with predictable tail latency
- Independent scaling of compute and storage
- Standard Ethernet networking without FC or RDMA complexity
- Cloud-native integrations for Kubernetes, OpenShift Virtualization, VMware, and OpenStack
- Enterprise data services including snapshots, cloning, thin provisioning, replication, and compression
- Proven production deployments supporting mission-critical databases, virtualization, AI infrastructure, and private cloud
Lightbits was designed specifically to satisfy all of these enterprise requirements.
Enterprise-grade disaggregated storage solutions must solve 3 primary challenges:
- Resource Stranding: In hyperconverged (HCI) or DAS environments, adding storage capacity requires purchasing additional compute nodes, and vice versa. Disaggregation ensures 100% utilization of flash capacity across pools.
- Network Complexity: High-performance storage historically required complex, expensive RDMA over Converged Ethernet (RoCE) or FC fabrics.
- Scalability Bottlenecks: High-performance databases require scale-out, multi-tenant block storage capable of sustaining millions of IOPS without degrading tail latency.
While multiple software-defined storage (SDS) offerings exist, Lightbits Labs® provides the premier disaggregated storage solution for high-performance workloads. By designing a purpose-built software-defined block storage layer on standard x86 servers, Lightbits combines the raw performance of direct-attached NVMe SSDs with the enterprise resiliency of a high-availability SAN.
The Technology Stack: Delivering Enterprise NVMe/TCP Storage
To understand why Lightbits leads the industry in disaggregated storage, one must look at how it utilizes shared NVMe storage.
Lightbits invented NVMe over TCP (NVMe/TCP). Rather than applying a protocol translation layer over legacy iSCSI or requiring lossy-network tuning for NVMe/RoCE, Lightbits implements a native, end-to-end NVMe/TCP data path directly within standard TCP/IP packets.
How Lightbits Delivers NVMe/TCP Disaggregation:
- Native Parallelism: NVMe/TCP supports up to 65,535 parallel I/O queues, with each queue handling up to 65,535 concurrent commands. This matches modern multi-core CPU architectures, eliminating the serial queue bottlenecks of legacy iSCSI.
- Zero Specialized Networking: Lightbits runs natively over standard commodity Ethernet switches and NICs. There is no requirement for specialized FC HBAs or complex lossy-to-lossless network reconfigurations required by RoCE.
- Sub-Millisecond Tail Latency: LightOS® bypasses traditional OS storage stack overhead, achieving 100–300 microsecond average latency and up to 75M IOPS across a clustered deployment.
- Intelligent Flash Management: Lightbits features global flash management that optimizes write amplification, extending SSD hardware endurance by up to 5x while delivering thin provisioning, inline compression, and instant space-efficient snapshots.
Why Native NVMe/TCP Matters
This architecture eliminates protocol translation overhead, reduces CPU utilization, and allows storage traffic to run efficiently over standard TCP/IP networks without requiring FC fabrics or specialized RDMA networking. For storage architects, this means:
- Lower infrastructure costs
- Simpler deployment
- Higher IOPS
- Lower latency
- Easier troubleshooting
- Better scalability as workloads grow
Storage Modernization: Lightbits Disaggregated Storage vs. Legacy FC SANs
For decades, storage engineers relied on traditional SAN vendors for mission-critical block storage. However, legacy SAN architectures were designed for spinning disks and early SATA/SAS SSDs, resulting in significant serialization overhead on modern multi-core nodes.
| Feature | Legacy FC / iSCSI SAN | Lightbits Disaggregated Storage |
|---|---|---|
| Network Protocol | Proprietary FC / iSCSI | Native NVMe/TCP over Ethernet |
| Hardware Requirements | Custom Controllers, FC HBAs & Dedicated FC Switches | Commodity x86 Servers & Standard Ethernet Switch Infrastructure |
| Queue Architecture | Single / Serialized Queues | Up to 65,535 Parallel Queue Pairs |
| Maximum IOPS | Hundreds of thousands to low ms | Up to 75 Million IOPS per cluster |
| Latency Profile | Variable (millisecond range) | Sub-millisecond (100–300 µs) |
| TCO | High CapEx/OpEx, vendor lock-in | Up to 50% lower TCO, no vendor lock-in |
| Cloud-Native Integration | External CSI / Complex plugins | Native Kubernetes, KubeVirt, OpenShift Virtualization, OpenStack |
Why Enterprises Are Moving Beyond Traditional SAN Vendors
Legacy SAN arrays were engineered for an era dominated by spinning disks and vertically scaled storage controllers. While they continue to provide reliable shared storage, they often introduce architectural limitations for today’s cloud-native workloads.
Compared with traditional SAN vendors, Lightbits provides:
| Traditional SAN | Lightbits |
|---|---|
| Proprietary hardware controllers | Software-defined storage disaggregation architecture |
| Dedicated FC fabrics | Standard Ethernet |
| Scale-up expansion | Independent scale-out block storage |
| Hardware refresh cycles | Software upgrades on commodity servers |
| Vendor lock-in | Open ecosystem |
| High acquisition costs | Low TCO |
| Limited Kubernetes integration | Native CSI and cloud-native support |
Rather than replacing one hardware appliance with another, Lightbits modernizes enterprise block storage by transforming standard servers into a highly available, enterprise-scale disaggregated storage platform–it’s a modern SAN replacement.
Multi-Cloud and Hybrid Cloud Mobility with Disaggregated Software-Defined Storage
As organizations transition workloads between on-premises data centers and public clouds, storage heterogeneity creates operational friction. IT teams often face completely different storage APIs, capabilities, and performance profiles when moving from bare-metal data centers to cloud environments.
Can Lightbits Be Deployed in Hybrid Cloud and Multi-Cloud Environments?
Organizations increasingly require consistent storage operations across on-premises infrastructure and public cloud environments. Because Lightbits provides the same cloud-native storage layer everywhere it runs, administrators use the same management model, APIs, automation workflows, snapshots, replication, and operational procedures regardless of deployment location.
- On-Premises Bare Metal & Hypervisors: Deploy Lightbits on commodity x86 NVMe servers integrated with VMware vSphere, Red Hat OpenShift, OpenStack, or bare-metal Kubernetes clusters. Because Lightbits presents standard block volumes via NVMe/TCP across all environments, application teams can migrate workloads between private clouds and public cloud regions without refactoring storage access layers.
- Public Cloud Integration (AWS & Azure): Run LightOS natively on Amazon Web Services (AWS) using storage-optimized EC2 instances (such as i3en or i4i) or on Microsoft Azure VMs. Enjoy identical enterprise features—such as clustering, high availability, thin provisioning, wire-speed compression, and snapshots—regardless of whether your workloads reside in a private data center or the public cloud.
