VirtuCache is Listed in VMware’s VAIO Compatibility Guide for Host Side Caching Software
This link on VMware’s website states that our host side caching software is on their Hardware Compatibility List (HCL) for VMware’s API for IO Filter (VAIO).
Its great to be on VMware’s HCL since some customers now might feel more comfortable with our software. But just to be clear, this listing in VMware HCL, doesn’t change either the features of VirtuCache, or the support escalation path for customers. We support all ESXi 5.x and 6.x versions in exactly the same way.
Since we have been asked this question by some customers, I want to clear up two misunderstandings about third party software that VMware certifies via their Hardware Compatibility List (HCL).
VMware does not support VMware certified products, the software developer does.
I want to dispel the misunderstanding that being on VMware HCL means that the software is supported by VMware. This is not true. VirtuCache is supported by Virtunet only. It cannot be supported by VMware simply because they don’t have our source code.
Being on VMware HCL does not improve the third party software.
Our listing on VMware’s HCL does not by itself result in any new features. Feature/function decisions for VirtuCache are entirely Virtunet’s and not VMware’s.
Also being on HCL doesn’t mean better interoperability with VMware. There is no interoperability testing that VMware does separately from what we have already done for VirtuCache.
The only thing that VMware’s HCL listing means is a confirmation from VMware that we are using VMware’s published APIs to develop VirtuCache, and they allow us to display the ‘VMware Ready’ logo on our marketing materials.
