We’ve all been there…
Maybe its the streets of NYC, or a corner stall in a mall in Bangkok, or even Harwin St here in Houston. Someone tried to sell you a cut rate watch or sunglasses. Maybe the lettering was off, or the gold looked a bit flakey but you passed on that possibly non-genuine watch or sunglasses. It might have even been made in the same factory, but it is clear the QC might have issues. You would not expect the same outcome as getting the real thing. The same thing can happen in Ready Nodes.
Real Ready Nodes for VMware Virtual SAN have a couple key points.
They are tested. All of the components have been tested together and certified. Beware anyone in software defined storage who doesn’t have some type of certification program as this opens the doors to lower quality components, or hardware/driver/firmware compatibility issues. VMware has validated satisfactory performance with the ready node configurations. A real ready node looks beyond “will these components physically connect” and if they will actually deliver.
VSAN Ready Nodes offer choice. Ready nodes are available from over a dozen different server OEM’s. The VMware VSAN Compatibility Guide offers over a thousand verified hardware components also to supplement these ready nodes for further customization. Real Ready Nodes are not limited to a single server or compoennt vendor.
They are 100% supported by VMware. Real VMware Ready Nodes don’t require virtual machines to mount, present or consume storage, or non-VMware supported VIBs be installed.
So what do you do if you’ve ended up with a fake ready node? Unlike the fake watch I had to throw away, you can check with the VSAN compatibility list and see if you can with minimal controller or storage devices changes convert your system in place over to VSAN. Remember if your running ESXI 5.5 update 1 or newer, you already have VSAN software installed. You just need to license and enable it!
