Formulus Black recently announced version 3.0 of its Forsa product. I had the opportunity to speak with Mark Iwanowski and Jing Xie about the announcement and wanted to share some thoughts here.
So What’s A Forsa Again?
It’s a software solution for running applications in memory without needing to re-tool your applications or hardware. You can present persistent storage (think Intel Optane) or non-persistent memory (think DRAM) as a block device to the host and run your applications on that. Here’s a look at the architecture.

Is This Just a Linux Thing?
No, not entirely. There’s Ubuntu and CentOS support out of the box, and Red Hat support is imminent. If you don’t use those operating systems though, don’t stress. You can also run this using a KVM-based hypervisor. So anything supported by that can be supported by Forsa.
But What If My Memory Fails?
Formulus Black has a technology called “BLINK” which provides the ability to copy your data down to SSDs, or you can failover the data to another host.
Won’t I Need A Bunch Of RAM?
Formulus Black uses Bit Markers – a memory efficient technology (like deduplication) – to make efficient use of the available memory. They call it “amplification” as opposed to deduplication, as it amplifies the available space.
Is This Going To Cost Me?
A little, but not as much as you’d think (because nothing’s ever free). The software is licensed on a per-socket basis, so if you decide to add memory capacity you’re not up for additional licensing costs.
Thoughts and Further Reading
I don’t do as much work with folks requiring in-memory storage solutions as much as I’d like to do, but I do appreciate the requirement for these kinds of solutions. The big appeal here is the lack of requirement to re-tool your applications to work in-memory. All you need is something that runs on Linux or KVM and you’re pretty much good to go. Sure, I’m over-simplifying things a little, but it looks like there’s a good story here in terms of the lack of integration required to get some serious performance improvements.
Formulus Black came out of stealth around 4 and a bit months ago and have already introduced a raft of improvements over version 2.0 of their offering. It’s great to see the speed with which they’ve been able to execute on new features in their offering. I’m curious to see what’s next, as there’s obviously been a great focus on performance and simplicity.
The cool kids are all talking about the benefits of NVMe-based, centralised storage solutions. And they’re right to do this, as most applications will do just fine with these kinds of storage platforms. But there are still going to be minuscule bottlenecks associated with these devices. If you absolutely need things to run screamingly fast, you’ll likely want to run them in-memory. And if that’s the case, Formulus Black’s Forsa solution might be just what you’re looking for. Plus, it’s a pretty cool name for a company, or possibly an aspiring wizard.
