Software-Defined Storage: StarWind Virtual SAN vs Microsoft Storage Spaces Direct vs VMware Virtual SAN

The article provides comparison of three leading products of the Software-Defined Storage market: Microsoft Storage Spaces Direct, VMware Virtual SAN and StarWind Virtual SAN. There are several use cases considered, based on the deployment scales and architectures.

Microsoft Storage Spaces Direct and VMware Virtual SAN are a perfect choice for bigger SMBs and entry-level enterprises because their licensing is reasonable for typical of these businesses infrastructure types. These solutions are not good with smaller SMBs and ROBOs, being too expensive and a performance overkill for them. The per-host licensing is too expensive for the hyperconverged environment of very big enterprises. Microsoft can expose only SMB3 reasonably well, while VMware “speaks” iSCSI and NFS, which prevents them from creating single shared storage pool in a multi-tenant environment. For the databases scenarios implementation, Microsoft and VMware have specific financial and technical issues.

StarWind Virtual SAN requires minimalistic two-node setup and provides 24/7 support, which makes it a perfect choice for small SMBs and ROBO. It has flexible licensing, to cover different deployment scenarios. StarWind utilizes the majority of industry-standard uplink protocols, so it can work with vSphere and Hyper-V environments simultaneously and provide a single pool of storage instead of separated “islands”. For datacenters, StarWind is good both in its software form as a “data mover” to create the virtual shared storage pool, and complete “ready nodes” for HCI or storage-only infrastructure. StarWind supports non-virtualized Windows Server environments, properly supports all possible storage protocols, and can provide high performance shared storage.

In general, StarWind Virtual SAN rather complements Microsoft Storage Spaces Direct and VMware Virtual SAN, than competes them. It fills the gaps for Microsoft or VMware-based infrastructures, providing them with the features to fine-tune different types of architectures.

Hyper-V VMs on NFS share? Why hasn’t anyone thought of that earlier? They did, in fact.

Some “wise guy” said he could store Hyper-V Virtual Machines on an NFS share. Sounds really convenient, but why didn’t anyone thought of that before? The problem is – they did, and they all failed. The abovementioned “wise guy” never actually told anyone how he managed to achieve that. Our curiosity outbalanced everything else, so here we are, trying to do what is thought to be impossible by everyone, but claimed to be real by one “hero”.

We decided to try three different approaches – as many as there are, in fact. The first is just trying to create a VM on the NFS share. The second is moving a previously created elsewhere VM to the NFS share. The third is manual copying a previously created elsewhere VM to the NFS share. If you know another way, contact us, please.

Read this article here https://blog.starwindsoftware.com/2015/01/14/hyper-v-vms-on-nfs-share-why-hasnt-anyone-thought-of-that-earlier-they-did-in-fact/ , see how we failed gloriously, or actually won in terms of our own opinion. NFS share was never meant to store Hyper-V virtual machines and it won’t. If anyone tells you otherwise, demand proof and send it to us. Because, you know, “wise people” talk a lot of their own genius, but often fail to back their words up with facts.
