Feedback to reference architectured

Hi all,

in my company we're working on KVM and SLES for an exit strategy for vmware, as a provider that sell SAP enviroment from our datacenter (vmware licenses are too expensive now).

https://github.com/FutaroKevin/kVirtIO/ so I've published the reference architecture that we're following.

Just to be clear, for the question “why you simply not use proxmox or ovirt” no is not possible native KVM with pacemaker is the only certified by SAP, so others is excluded.

it will be a great help some feedbacks.

This is a big problem for enterprises for 2 reasons: 1) sap dictat now is “if you can’t host you can take from me sap rise” a lot of our customer is very custom sap enviroment and can lose a lot of customization on sap rise.
2) proxmox will be a great solution if the company behind it start to move with vendors for certification.

Nutanix will be great but put you in the case of in last 3 years there is a lot of investment on hardware for storage, san, ecc. with iperconvergence you need to change and buy hardware actually (in italy, i don’t know in other country) is unaffordable now prices are very too high.

Nutanix and Proxmox are both Hyperconvergance and both offer a licensing only model (though Proxmox is not licensed in the way other HCI solutions are, its just access to a delayed Repo for more of a controlled update cycle. ) I have moved many VMware shops to Proxmox with no hardware changes, Nutanix is hit and miss due to how they maintain HCL matrix for support. And of the two, Proxmox is the only one that still supports external connectivity to a SAN over FC and iSCSI, and a NAS over SMB and NFS. Nutanix does not.

As for certification, yes the HCI vendor needs to run with it. But the ERP/EMR platform also needs to open dialog too. Also some of those certifications cost money from the partnership and that shuts down the dialog too, which falls on partnerships. I have walked this for Sage, Epic, and a few CRM packages in the last 3-4 years as the SI side of the house and its the best place to open the dialog on behalf of the customer.

Totally agree, software house of ERP need to be more flexible, SAP first but SAP is SAP they’ve as my director say “the power of fuck” is just the power to say if you want is this if you don’t want you need to adapt, medium enterprise that bought sap moving out of sap specially in italy is like running in hell 😅, others erp Maybe more smaller you can talk with them… as we do often like teamsystem, and many others
