Innovative Data Storage Can Save Cash, Headaches, and Your Data
Storage Downtime is Unacceptable
When the network goes down, everyone is mildly annoyed, but when the storage goes down, “Everyone loses their mind, ” as the Joker would say. And for good reason. No one likes losing payroll data, shipments, customer information, financial transactions, or CRM information… And they certainly don’t like waiting while you roll back to your latest backup. Internally and externally, data-loss and downtime wastes valuable resources and it hurts company reputation. Downtime is becoming less acceptable every day, and data-loss, even more so. Stable, safe, and secure storage should be a priority for those responsible for protecting their business (just ask Equifax).
Due to the increasing need for high availability (HA) and disaster recovery (DR), proprietary storage companies like NetApp and Dell EMC have provided SAN and NAS technologies to protect your organization’s most important data. These hardware appliances, many times, have no single point of failure, synchronous data replication and even a nice GUI so that users can point-and-click their way around. The downside? These storage appliances aren’t scalable and they are expensive. Really expensive.
The Obvious (or not so obvious) Alternative
Did you know that resiliency is built into your Linux OS? That’s right, built into the mainline linux kernel is everything you need to replace your shared storage. For over 15 years, LINBIT has been creating the DRBD software, designed to synchronously replicate data between Linux servers seamlessly just like your SAN. It can even trick the application above to believing they are writing to a SAN, when in reality, it is standard X86, ARM, or Power boxes. The full LINBIT HA solution combines the DRBD software with open source fail-over software as well. This combination eliminates the need for proprietary shared storage solutions. So, why aren’t you using it? You probably didn’t know that it existed.
For the past 20 years, those with IT know-how, and small budgets found that HA clustering, using commodity off-the-shelf hardware, was an affordable alternative to traditional storage methods. This crowd consisted of the standard Linux hacker rolling out a home-brewed web-server, and the hyperscale players who didn’t want to rely on outside vendors to build their cloud. Being that these hyperscale companies are using the software to create a competative advantage against their competitors they aren’t all-that-eager to share their stories. They have kept the mid-market in the dark.
Almost all of the major players (including Google, Cisco, Deka Bank, HP, Porsche, and the BBC) have realized that using standard hardware instead of proprietary appliances creates a competitive advantage. Namely: inexpensive resilient storage that their competitors are paying an arm and a leg for. Now, the storage industry’s best kept secret is finally out.
It Doesn’t Stop There
LINBIT is pioneering open source SDS. In development for over 7 years, the new solution will create standard High Availability clusters like described above, and also work perfectly for cloud storage. The LINBIT SDS software introduces performance advantages scalability to the design. LINBIT’s created a sort of “Operating System based,” Open Source, Software Defined Storage technology that is already built into your existing operating system and ready to use with any Linux system.
The Default Replication Option
LINBIT’s DRBD software receives about 10,000 confirmed downloads per month (people who opt-in to show their statistics). LINBIT is far more engineering and development focused than sales focused so if you aren’t solving a real-world problem you have probably never ran into them. LINBIT’s software popularity is user driven, and due to 3 main reasons:
Flexibility: Since the DRBD software replicates data at the block level, it works with any filesystem, VM, or application that writes data to a hard drive. It can replicate multiple resources simultaneously so users don’t have to choose different replication technologies for every application/database running on the server.
Stability: Being accepted into the mainline Linux kernel is a very stringent process. DRBD has been in the kernel since 2009, version 2.6.33
Synchronous: Prior to DRBD’s availability (no pun intended), the only option for synchronous replication was hardware (SAN, NAS devices). The DRBD software can run in synchronous or asynchronous mode, and be used for local replication or Geo Clustering across long distances.
Now that DRBD has tools to provision your storage, scaling out has never been easier. Interested in how this might apply for your projects? Check out some of LINBIT’s (free) innovative technical documents which describe how to set up a cluster for your specific environment. Have an idea that isn’t covered in the documentation? Reach out to [email protected] and ask if your idea is sane. They’ll consult the LINBIT engineering team, and will point you in the right direction. Most importantly, NEVER settle for unplanned downtime.
