LINBIT Announces Competitive Replacement Program Targeting Ceph OpenStack Cloud Users

With LINBIT DRBD-SDS, “Project Lightning” offers OpenStack Cloud Customers Lower Cost and up to 6x Better Performance

“We have found LINBIT’s DRBD-SDS to be the highest performing option for our cloud deployments, which in turn lowers costs and improves quality of service for our customers.” – Jiří Purš, CEO of Pro-Zeta a.s.

LINBIT, the de-facto standard in open source high availability software for data management, today announced a competitive replacement program targeted at users of Ceph, an alternative distributed data storage software. LINBIT’s solution is based on DRBD, the industry’s highest performing and most widely deployed open source data management software for high availability (HA), disaster recovery (DR), and software defined storage (SDS).

“Operating in 6 countries and 15 data centers in Central Europe and Asia, Prozeta Virtual Datacenter delivers a wide range of solutions and services in the cloud,” said Jiří Purš, CEO of Pro-Zeta a.s. “We have found LINBIT’s DRBD-SDS to be the highest performing option for our cloud deployments, which in turn lowers costs and improves quality of service for our customers.”

In a series of benchmark tests to assess the relative performance of stock software in typical installations, LINBIT engineers found DRBD-SDS (DRBD9 9.0.5rc1-1 and DRBD Manage 0.97.5) to be up to 6x faster than Ceph 10.2.3 while consuming 20x less CPU resources. The LINBIT advantage was especially notable for small block-size I/O where most customer applications operate.

Dubbed “Project Lightning” for its ability to take customers’ cloud applications straight to kernel-level performance, LINBIT’s program offers six months of free enterprise support for Ceph customers who choose to deploy DRBD-SDS. This can result in improved application response times, lower hardware and licensing costs, better capability to manage peak loads, and the ability to support more users. Customers can register for the program at and may contact LINBIT for assistance in evaluating their specific installations and business objectives.

Project Lightning targets the overwhelming majority of OpenStack cloud installations and typical application workloads: 2-256 nodes, block I/O, fast I/O operations, and topology-aware data management that is well-suited for the increasingly popular converged infrastructure sites.

“With 10,000 downloads per month, a 15 year history, and thousands of installations worldwide, LINBIT DRBD-SDS is proof that open source software can serve mission-critical enterprise environments,” said Philipp Reisner, CEO of LINBIT. “Today, LINBIT is bringing its proven capabilities to cloud computing and software-defined-storage, demonstrating that high availability does not have to come at the expense of high performance.”


LINBIT is the force behind DRBD and the de-facto standard in open source high availability software for data management. DRBD is deployed in thousands of mission-critical environments worldwide to provide high availability (HA), geo-clustering for disaster recovery (DR), and software defined storage (SDS) for OpenStack based clouds.

LINBIT and MySQL Partnership

DRBD® assures the high availability of databases

The provider of the world’s most popular Open Source database and the austrian technology leader for Open Source solutions have concluded an agreement for cooperation. Therewith, MySQL AB and the Viennese LINBIT Informaton Technologies GmbH now share the same approach in terms of high availability. All MySQL business clients benefit from this, as they now get direct support for the DRDB high availability solution. Phillip Reisner, mastermind of the DRBD Linux kernel module and LINBIT CTO, recently signed the contract at the MySQL-conference in Santa Clara.

“Until now, only large enterprises were able to afford high availability databases”, says Ulf Sandberg, Vice President of Services of MySQL AB. “Now, the combination of MySQL Enterprise and DRBD makes high availability accessible for all companies that need a cost efficient Open-Source-solution for their business-crucial web appearances and IT applications”, Sandberg continues.

“With an availability of 99.999 percent, MySQL has already been complying with high requirements. With DRBD we have proven to numerous clients that 100 percent of availability are possible. That is the level we now want to offer to all MySQL-clients, too” explains Philipp Reisner, who also considers the contract with MySQL AB a huge boost for LINBIT. After all, MySQL is the database with the fastest development in the economy. With more than eleven millions of active installations and 50.000 downloads a day, MySQL is used by more and more developers, database administrators and IT-managers who want a high-performant, reliable and user-friendly database.

Just like MySQL AB, LINBIT believes in the development of competitive solutions. With DRBD (Distributed Replicated Block Device), failure-proof applications and data for companies of every size become affordable and savings up to 90 percent are possible. Since January 2007, DRBD is available in version 8. The most important innovation in version 8 is the support of Clustering filesystems just like GFS and OCFS2, meaning that two nodes in a cluster can actively access a DRBD in read and write mode at the same time. Furthermore, the version 8 has a large number of small improvements in terms of performance, Split-Brain avoidance, conflict solution after a Split-Brain, metadata tools and in dealing with Input/Output (IO) errors.

About MySQL AB

MySQL meets the Open-Source-values as well as the requirements of business clients in a profitable, sustainable business model.

Competitive Enterprise Storage Solution based on DRBD

LINBIT®: It doesn’t always have to be SAN

Storage Area Network (SAN) isthe magic word for safe storage solutions. However, as SANs are based on Fibre Channel (FC) hardware, they usually are expensive due to the need of special hardware and switch components as well as fibre channel cables. LINBIT, the Viennese technology leader in terms of Open Source solutions, thus developed a competitive alternative that combines standard storage hardware with the ethernet standard. Despite the excellent cost/performance ratio, this ethernet-based technology together with the iSCSI-technology even provides you with a better storage bandwith (10 Gbit/s) than Fibre Channel (4 Gbit/s).

Established SAN solutions require you to install special fibre channel cables to connect the storage- and productive systems. For security reasons, the locations of these systems should be as far away from each other as possible, making even the cable installation as such very expensive. For example, EMC as provider for data mirroring explicitly asks for a single fibre cable, a so called “dark fibre?, that is not used for anything but the mirroring. At least, EMC offers a redundant SAN that way – other companies don’t even have redundancy in their portfolio. Other providers only offer asynchronous mirroring instead of synchronous mirroring. “Because the data transfer drags behind in such setups, there is always the danger that after a failure, not all data is available anymore?, says Philipp Reisner, LINBIT CTO, uncovering the disadvantages of such installations.

Reisner, whose Linux kernel module DRBD (“Distributed Replicated Block Device?) is used in hundreds of thousands of high availability-solutions all over the world, enhanced his high availability concept for the storage-area and convinced even large companies completely. In open competitive biddings, LINBIT runs against the large SAN-specialists more and more often. While these players offer expensive hardware with just as expensive service contracts, LINBIT,based on its intelligent solution, can extend storage-servers with each and every piece of hardware and completely independant from the hardware provider.

With an annual growth of the data volume from 30 to 50 percent, the servers have to be upgraded on a regular base. Thanks to LINBIT, such upgrades can be done with every available piece of hardware at any time and, which is the most important factor of all, without an interruption of the service. That even applies to all maintenance work that needs to be done. While non-redundant SAN-solutions have to be taken out of service during maintenance, the iSCSI Storage Area Networks by LINBIT can undergo maintenance during the normal operation. DRBD redirects all recent jobs automatically to the redundant server so that end-users can just continue their work without interruption.

LIBINT implemented SAN on the base of the IP protocol, getting along without Fibre Channel and the expensive components needed for it. The LINBIT-solution works over standard ethernet cables, a server-cluster with DRBD supersedes the expensive storage box needed for fibre channel. The storage and production servers are connected via standard NICs and the iSCSI-protocol (iSCSI meaning “Internet Small Computer System Interface”). The synchronous mirroring is done by DRBD. Even the switches are laid-out for redundancy. If a FC-connection between two locations fails, the mirroring is interrupted but the users continue to have access to the servers. The replication starts again once the broken network component was exchanged. If a server crashes, users can continue to work with the remaining servers – these changes are even done transparently. In cases where just a single disk crashes, all processes can be conducted on redundant disks.

“Those who want to consolidate dozens of hard disks in a single SAN storage box had to invest loads of money into quite a lot of hardware so far, accepting huge costs for reliability. With iSCSI and DRBD we can now offer an alternative that is ten times less expensive”, summarizes Philipp Reisner the advantages of the Linux-based solution.

DRBD for MySQL: One Year Down, Going Strong

LINBIT looks back on first year of cooperation with MySQL/Sun Microsystems

As the 2008 MySQL Conference & Expo has wrapped up, LINBIT looks back on an extremely successful first year of the cooperation that brought Four-Nines High Availability to MySQL Enterprise. Since the Database Group at Sun Microsystems – formerly MySQL, Inc. – integrated LINBIT’s open-source, shared-nothing, synchronous block replication technology DRBD® into MySQL, Sun customers world-wide have adopted the integrated offering in numbers surpassing all projections. This includes industries as diverse as printed media publishing, hotel reservation services, interactive online entertainment, and education, to name a few.

Philipp Reisner, co-CEO at LINBIT comments that “MySQL has boosted our visibility in the North American and other markets on an enormous scale.” He goes on to say, “Our cooperation, and the strong endorsement Sun is putting behind us, show that LINBITis a well-established  technology leader for open source high availability, serving customers and partners around the globe.”

Florian Haas, LINBIT’s partner relationship manager and the Sun Database Group’s “go-to guy” at LINBIT®, adds that “the MySQL support, professional services, and sales organizations continue to impress us with their professionalism, enthusiasm, and constant drive for excellence. This has been a fantastic year for us and we only expect it to get better now that after the Sun acquisition, our technology is backed by a 34,000-people technology giant.”

The conference, coinciding with LINBIT’s launch of a completely remade all-new website ( this year, brought together over 2,000 MySQL users, customers and partners from around the world and is held annually in the United States during the month of April. LINBIT presenters delivered a well-received tutorial and presentation.

DRBD, LINBIT’s key technology offering, is an open-source, shared-nothing, synchronous replication solution for the Linux platform. An application neutral technology licensed under the GPL, it adds High Availability capability not only to databases, but also to virtualization, file services, and much more.
