Lightbits redefines how storage is managed and delivered in OpenStack and KVM cloud environments.
What is OpenStack cloud storage? OpenStack cloud storage is about transforming a standard data center into a high-performance private cloud that rivals the speed of other cloud offerings. Lightbits LightOS is a high-performance, software-defined storage solution that seamlessly integrates with OpenStack’s block storage service, Cinder. It introduces NVMe/TCP-direct storage to the ecosystem enabling OpenStack clouds to achieve the performance of local flash while maintaining the flexibility and efficiency of networked, pooled storage.
Does Lightbits solve the common challenges of OpenStack storage? Yes, Lightbits block storage solves the bottlenecks of legacy architectures, such as Ceph, iSCSI, or DAS which struggle to keep up with the demands of modern, performance-intensive private clouds.
- Lightbits eliminates application stalls and accelerates database transactions with low latency, high IOPS and throughput.
- Lightbits’ disaggregated architecture eliminates overprovisioning and idle CPUs, reducing data center footprints, lowering CapEx and power consumption.
- Lightbits eliminates Ceph’s operational tax. Storage is automated through the Cinder driver with simple “Day 2” operations.
- Lightbits needs no specialized network, proprietary NICs, switches, or dedicated cabling, which increases costs and limits flexibility. NVMe/TCP delivers FC speeds over the standard Ethernet you already own.
- Lightbits delivers consistent sub-millisecond latency even under heavy load so you never miss an SLA, enabling you to execute live VM migrations and delivers more uptime.
Lightbits storage for OpenStack can be run on commodity hardware and seamlessly integrates into your desired architecture for faster deployment of cloud services. Engineered for high performance, cost-efficiency, and resiliency Lightbits will efficiently scale in lockstep with your business demands. delivering the best price-performance value for OpenStack clouds while delivering a solid user experience.
5 Reasons Why Lightbits is Ideal for OpenStack
Unmatched Parallel Performance
Lightbits storage software enables you to effortlessly create hundreds of new PVCs at scale without compromising IOPS or increasing latency for your running applications.
Peak Performance for Every Volume
Lightbits ensures unmatched IOPS and ultra-low latency, delivering industry-leading performance at scale even when demand for volumes grows exponentially.
Effortless Live Migration with OpenStack Volume Retype
Seamless integration via the OpenStack Cinder driver, enabling effortless migration between volume types with zero performance bottlenecks—empowering you to retype multiple volumes simultaneously without compromising speed or efficiency.
Disaggregated Storage
By separating storage from compute resources, you can expand storage capacity independently of compute power, enabling seamless scaling and cost-effective growth without limitations. This is particularly ideal for environments like OpenStack, where managing large-scale VMs and block storage volumes can be a challenge.
Scalability, Resiliency and Cost Effectiveness
Lightbits’ software-defined, disaggregated architecture enables independent scaling of compute and storage, offering unparalleled flexibility to meet evolving workloads and business needs. High availability is ensured through seamless storage server failover, safeguarding business continuity even during hardware failures. By leveraging standard Ethernet networks and NVMe/TCP, Lightbits reduces infrastructure costs while extending SSD lifespans with Intelligent Flash Management. With Lightbits, you can achieve the perfect balance of performance, reliability, and cost-effectiveness, redefining what’s possible in modern storage environments.

OpenStack Cloud Storage: Common Questions Answered
What storage services are included in OpenStack (Cinder, Swift, Manila)?
- Cinder provides persistent block storage to VMs. Lightbits LightOS provides a Cinder Driver that replaces slower backends, such as iSCSI or Ceph RBD, with NVMe/TCP. It allows OpenStack to treat Lightbits storage as a high-speed, scalable pool of flash. Use cases include databases (SQL/NoSQL), boot disks, and any application requiring low-latency performance.
- OpenStack clouds use Swift for massive-scale object storage, Lightbits block storage is used as a performance-heavy workload tier that Swift isn’t designed to handle. Swift use cases include storing large amounts of static data like images, video files, backups, and machine learning datasets.
- Manila provides a Shared File System service. Platform architects often use Lightbits Cinder volumes as the underlying storage for high-performance file servers that then export NFS shares to the rest of the cloud.
How does OpenStack storage work in private clouds?
In a private cloud, OpenStack storage works as a collection of specialized services that abstract physical hardware into virtualized pools. Lightbits makes provisioning storage services significantly faster and more efficient. Lightbits Cinder driver acts as the translator between OpenStack’s high-level commands and the Lightbits storage cluster.
OpenStack Cloud Storage: Common Questions Answered
- What is the best block storage backend for OpenStack Cinder? The best backend depends on workload needs, but NVMe/TCP-based software-defined storage (e.g., Lightbits) is increasingly preferred for high-performance, low-latency environments.
- How does OpenStack handle HA storage? Through backend replication/erasure coding, multipathing, and failover mechanisms managed by Cinder and the storage platform.
- What are the performance requirements for OpenStack workloads? Modern workloads require sub-ms latency, high IOPS, and consistent performance under load.
- How does OpenStack storage integrate with compute and networking? Via Cinder drivers connecting storage to Nova and Neutron, forming a tightly coupled data path.
- How does Ceph compare to other OpenStack storage backends? Ceph offers flexibility and scalability but can introduce latency and operational complexity, whereas modern SDS solutions like Lightbits LightOS prioritize performance and simplicity.
