VMware has published a blog post announcing a VSAN Ready Nodes from Dell, Fujitsu, HP and SuperMicro. You'll be able to download a PDF from this post, where you'll see the specifications and details concerning each node. I have reported already on the way to check the existing hardware parts for compatibility for VSAN in my article here, but the ready nodes were not available at that time.
Interesting approach by VMware is that they actually classifies those pre-configured servers by different profiles depending what you actually want to run as workflow – VDI or Server workload.
VSAN ready nodes
Here is quick quote from the post:
What are the different solution profiles under which Ready Nodes are classified?
Virtual SAN Ready Nodes are classified into Low, Medium and High profiles for Server workloads and Full Clone & Linked Clone profiles for VDI workloads. The solution profiles provide prescriptive hardware recommendations to meet different levels of workload requirements based on the maximum number of VMs (assuming an average instance size for each VM) that can be run per host.
The PDF document lists all the ready nodes currently available. You can also go Online on VMware HCL VSAN compatible hardware resource page where you can choose between compatible parts for VSAN (HDD, SSD or I/O controller cards) or Virtual SAN ready node PDF document. It's the same download.
Quote from the PDF:
Virtual SAN Ready Node is a hyper-converged node sold by server OEMs, which in many cases, has been pre-conﬁgured to run the Virtual SAN + vSphere stack in a tested, certiﬁed hardware form factor. The Virtual SAN Ready Nodes include unique and optimized hardware from the OEM, and may also include software from the OEM to complement Virtual SAN + vSphere. Virtual SAN Ready Nodes are ideal as hyper-converged building blocks for larger datacenter environments with strong automation and a need to customize hardware and software conﬁgurations.
Virtual SAN Ready Nodes are also prescriptive in that they provide the size, type and quantity of CPU, Memory, Network, I/O Controller, HDD and SSD combined with a certiﬁed server that is best suited to run a speciﬁc Virtual SAN workload.
