LINBIT and OpenNebula Launch Reference Architecture for Container-Native Software Defined Storage (SDS)

VIENNANov. 8, 2018 – LINBIT, the pioneer in Linux-based Software Defined Storage (SDS) built on open source high availability, disaster recovery, and container technologies, today announced a reference architecture for SDS in collaboration with cloud platform leader OpenNebula. The architecture demonstrates how a container-native SDS solution can be deployed easily and deliver unprecedented speed and reliability. The companies have installed a powerful representative configuration in Frankfurt, Germany at a modern facility provided by e-shelter, one of the top data center operators in Europe.

LINBIT SDS is the only SDS solution that augments, rather than duplicate the storage management functionality that is already available in the Linux operating system,” said Brian HellmanLinbit COO.  “This simple but novel approach translates to a reliable feature-rich solution for large and small enterprise customers.”

Volume and configuration management is provided by LINSTOR, a software tool that serves as management console for LINBIT products, while fast and reliable data replication is delivered by DRBD, a part of the Linux kernel for nearly a decade.

“OpenNebula over LINSTOR enables a fully hyper-converged cloud with state-of-the-art orchestration and storage features, using OSS components exclusively,” said Constantino Vázquez, Engineering Manager at OpenNebula Systems. “The integration between the two couldn’t be more natural – they are a perfect fit.”

LINSTOR simplifies the management of block storage devices for Linux server clusters of any size. In addition, it is fully integrated with Kubernetes and OpenShift, which simplifies building, running, and controlling block storage.

OpenNebula is a turnkey enterprise-ready solution that includes all the features needed to provide an on-premises (private) cloud offering, and to offer public cloud services. Red Hat OpenShift is an open source container application platform based on the Kubernetes container orchestrator for enterprise application development and deployment.

The facility enable companies to test the full range of the OpenNebula and LINSTOR functionality with easy access, within minutes, and access to a pre-build configuration. Customers who are interested in running a test using the system may contact their LINBIT sales representative. For more information, please visit www.linbit.com.

About LINBIT 
LINBIT is the force behind DRBD and the de facto open standard for High Availability (HA) software for enterprise and cloud computing. The LINBIT DRBD software is deployed in millions of mission-critical environments worldwide to provide High Availability (HA), Geo Clustering for Disaster Recovery (DR), and Software Defined Storage (SDS) for OpenStack and OpenNebula based clouds.

About OpenNebula 
OpenNebula is the open-source platform of choice in the converged data centre, providing a simple, albeit flexible and powerful, cloud manager that supports traditional IT features such as fault tolerance and failover; the dynamic provisioning, elasticity and multi-tenancy of modern enterprise clouds; and connectors for external clouds. With tens of thousands of deployments, OpenNebula is parked in some of the biggest organizations. OpenNebula Systems is the company that manages the OpenNebula Project and provides enterprise-grade support services.

FINALLY! Open Source Deduplication for Linux!

We’ve been working with our partner, Permabit, for a couple of years now. Permabit is the author of VDO, a block level deduplication software for Linux. Pair this deduplication software (which also has optional compression) with our DRBD software, and you get extremely efficient, low overhead, data replication.

The problem is Permabit built a solution that isn’t Open Source. Due to proprietary licensing, many users were instead deciding to install the ZFS filesystem on top of RHEL. This was the “free” way to gain Unix feature-sets on the Linux platform. We understand that ZFS has its benefits, but from the block level, installations can get sticky since it isn’t “just” a filesystem; it’s also a volume manager (zpool). ZFS likes to control the whole stack, which doesn’t play well with our DRBD replication software in some use-cases.

This is why we were ecstatic when Red Hat just announced that LINBIT partner, Permabit, was acquired by Red Hat. Red Hat hasn’t announced news of Open Sourcing the VDO solution yet, but they do have a very strong track record (100%) of doing so for products that they purchase.

“We are so excited to see that Linux will soon have a native deduplication and compression option,” said LINBIT CEO, Philipp Reisner. “We know that users who want seamless data-replication, deduplication, and compression, now need to look no further than their Operating System.”

As a strong Red Hat partner, we look forward to continuing to make the Linux platform the best it can possibly be. LINBIT recently announced Geo Clustering with automatic Oracle Dyn DNS failover and ActiveMQ High Availability and Disaster Recovery. Open Source VDO is one more tool which will help LINBIT build better availability solutions for our end clients.

DRBD 9 over RDMA with Micron SSDs

We have been testing out some 240GB Micron M500DC SSDs with DRBD 9 and DRBD’s RDMA Transport layer.  Micron, based in Boise Idaho, is a leader in NAND, flash production and storage.  We found that that their M500DC SSD’s are write optimized for data center use cases and in some cases exceeded the expected performance.
