Hyperconverged systems, SDS

Increasingly, we are reaching for hyperconverged technologies when designing IT infrastructure. They are based on replacing conventional disk storage attached to servers with storage built directly on top of the internal disks in the servers. Depending on the type of hyperconvergence, there can be anywhere from two to thousands of servers. High availability at the storage layer is a fundamental, inherent characteristic (data is always in the system at least twice). NVMe technology enables performance and latency comparable to traditional storage.

We most often design, deploy and run VMware (vSAN) and Microsoft (MS Azure Stack HCI) technologies for the long term. In addition to Software Defined Storage, all virtual servers run in VMware vSphere or MS Hyper-V environments. That's why we actually talk about hyperconvergence.
