Lightbits receives NVMe / TCP certification, enters the company’s software defined storage ring – blocks and files


With vSphere 7 Update 3, the startup Lightbits received the NVMe / TCP certification from VMware for its LightOS software and is now in direct competition with other NVMe / TCP storage providers.

LightOS is a storage array controller product with NVMe / TCP and offers independent scaling of computing power and storage on off-the-shelf hardware. It supports Intel’s Gen-3 Xeon SP processors, Optane Persistent Memory and 100 Gbit / s Ethernet NICs and QLC SSDs. A single LightOS cluster can deliver over 40 million IOPS (Random Read) and 10 PB user capacity with less than 200 μs latency.

Kam Eshghi, Chief Strategy Officer at Lightbits, quoted: “We are delighted to be able to offer VMware users a high-performance, high-availability storage solution with in-box support for NVMe / TCP. Companies with private clouds and hybrid clouds as well as cloud service providers and financial service providers can now use the performance, scalability and cost-efficiency advantages of a combined solution from VMware, Lightbits and Intel. “

Intel’s Chief Strategy Officer for its data platform group, Remi El-Ouazzane, endorsed Lightbits in a statement: “Intel high-performance hardware network adapters, Intel Xeon Scalable Processors, Intel Optane Persistent Memory (PMem) as DDR replacement and write buffers are essential to the promise of NVMe / TCP to meet. The integration of LightOS with Intel technology, especially with regard to QLC SSDs, for VMware environments optimizes cost efficiency and lowers the total cost of ownership with high performance and very low latency at the same time. “

Performance and costs

Basically, Lightbit’s message is equivalent or better data services and faster memory access performance at a lower cost. We understand that Lightbits NVMe / TCP generally scales linearly with over 6x more IOPS compared to iSCSI with the same number of threads and at the same time achieves up to 4x lower latency compared to iSCSI (on the same hardware).

It will reveal more performance data at a VMworld event this week.

The company has announced that it is reducing a customer’s storage TCO by:

  • QLC SSDs, ~ 30 percent lower cost than TLC SSDs;
  • Higher density per storage node, which amortizes the fixed costs of the storage server through greater capacity;
  • Compression reduces flash costs (depending on workload);
  • No hypervisor required on the storage node (no license fee).


As NVMe / TCP becomes increasingly important in storage networking – look at the multitude of vendors that support it – Lightbits is competing on the level playing field of the software defined storage market looking for greenfield wins and iSCSI upgrades.

It competes with other NVMe-oF providers such as Excelero as well as QLC Flash and Optane-supporting providers such as StorONE and VAST Data. On the NVMe / TCP front, it faces Dell, NetApp, Infinidat and Pavilion Data and could find fertile ground for attacks on HPE accounts as they don’t yet have NVME / TCP support. Ditto IBM. The iSCSI upgrade market in the two installed bases could be a fertile hunting ground.

It is not enough to be a fast access NVMe / TCP target. Lightbits has to compare competing providers with their various data services. LightOS supports multi-tenancy, thin provisioning, snapshots, clones, remote monitoring, dynamic rebalancing, SSD-level Elastic RAID, replication per volume, cloud-native applications, Kubernetes orchestration and more. Its SSD management improves flash endurance up to 20 times, which is good as it supports low-life QLC flash drives.

LightOS is listed in the VMware Compatibility Guide and LightOS Software-Defined Storage with Intel High-Performance Hardware for VMware ESXi 7.0U3 is now generally available.
