Software Defined Storage (SDS) was supposed to revolutionize storage, freeing IT from the chains of vendor lock-in, allowing them to build more cost effective scalable architectures. The first generation of SDS solutions, for the most part emulated the dedicated storage software that came on hardware, it just abstracted it so it could run on a variety of hardware. Part of that emulation means implementing storage features the way they have always been implemented instead of modernizing and taking advantage of modern hardware and software development techniques.
Building on a foundational premise of efficiency, the next generation of SDS, Holistic SDS, starts from scratch, instead of repurposing old code, to exploit multi-core processors fully, as well as memory based storage and high performance networks. It also replaces archaic algorithms, like RAID and volume management, with new ones that are faster, require less processing power and are more scalable.
Our new white paper “What is Holistic SDS?” explains the problems with the current generation of SDS and how Holistic SDS fixes those problems, enabling IT to create a high performing but cost efficient storage architecture. The paper is available exclusively to registrants of our on demand webinar “SDS is Broken – How to Fix It”.
