Custom Ready Node vSAN (Supermicro HY-6: 2UTwin²Pro)

[andiag1406]

Hi Everyone,

I'm a Presales Engineer for Supermicro Partner in my country, I'm nuwbie about vmware (espicially on vSAN Product),

I have some basics questions:

I've potential customer who want to deploy vSAN for CLoud Provider Infrastructure. I want to give a recommendation SuperMicro vSAN Ready Node Supermicro HY-6: 2UTwin²Pro (2029TP-HC0R ( 4nodes in 2U form)), with some of Spec detail :

- 8x CPU Intel 6230 20cores 2.1GHz (2CPU per Node)

- 48x 32Gb DDR4 2666 (12dimm x 32GB per Node)

- 4 SSD 480GB SATA (1SSD per Node)

- 16 2.0TB SAS HDD 2.5" (4HDD per Node)

- 4x SMC 3008 for Storage Controller (1x per Node)

The Question, can 1 custom this basic Spec of Ready Nodes with detail of Question :

1. Can i downgrade for every CPU from INtel 6230 to Intel Silver 4210 or 4214 ?

2. Can I downgrade Memory Quantity from 48 x 32GB (12 x 32GB per Node) to 12 x 32GB (4 x 32GB per Node) ?

3. Can I upgrade the SSD Capacity for every SSD from 480GB to 960GB ?

4. Can I Add 1 Disk for every Node, as info the Node Server basicly has 6x 2.5" SAS/SATA Drive Bays ( I expect 5 drive bays already used for 1x DIsk for Cache tier and 4x for Capacity Tier and 1 slot remaining) ?

Thanks and really hope for advice from the masters

Hello andiag1406​,

Welcome to Communities.

Only upgrade (not downgrade) of most components is supported while still considering it a ReadyNode:

VMware Knowledge Base

It could still be a supported vSAN configuration if all the swaps/addition cache/capacity devices are on the vSAN HCL but it wouldn't technically be a ReadyNode with the changes you suggest.

HI TheBobkin​

Thanks for your advised, the the reference link that you gave provided the all answer of my questions.

I think custom of spec which i've plan above is technically working for vSAN , but i'm not sure about the Support of vmware cause it's violating policy

[TheBobkin]

Well the first thing I would say that if indeed lowering the CPU/Memory capabilities of the server made it be considered 'not a ReadyNode' then technically it wouldn't be supported to use SAS-expanders.

This is a fairly corner-case - I would advise contacting vSAN Hardware PM at vsan-hcl@vmware.com who may be able to provide further clarification, let us know if there are any further insights from this.
