All right, pet? Getting owlish about Hedvig

Re: Nice marketing, but ..

I think this discussion could go on for some time as we appear to have different views on the subject and the Internet is an infamous platform for disagreements! :-)

But simple answer to your simple question, we process the heavy NFS protocol and metadata operations across multiple nodes, as many as we have in the cluster. The same for object and block. And yes metadata is fully distributed across the cluster, I don't think sharding is the right term, but that's a pedantic technicality and our implementation of distribution has some similarities.

I think we are being fully transparent, at no point do we say that we are a true object based storage system. In fact we try to actively point out that we are not as we think that introduces some compromises for block and file based requirements, but that's maybe another conversation. We have an object API and we don't think this makes us an object based storage system, but we do think it means our customers don't need to buy a dedicated object storage.

Re: Nice marketing, but ..

Hey Yaron, thanks for the comment. Honesty first, I am a Hedvig employee, but on the technical side!

So we're not a scale-out NAS for user file data, but we are a scale-out NAS for applications. I'm a massive fan of NFS for VMware and we work great there, in a proper scale-out way. We also do scale-out Object and as you say we also do block. But there's no standard Linux FS installed on top of it either.

Our metadata is very much distributed, but yes the value of metadata is limited in a block world, it's more for our own operations than anything. File and Object metadata is fully distributed and responds how you expect it.

In terms of the Scale-IO comparison, we offer some additional things such as deduplication, compression and something that I honestly think is killer, being active in multiple locations. We’re a clear path for customers doing hybrid cloud.

Flash and trash? You could begin with cache and trash

Definitely what we do here at Hedvig, without the idea of trash. Take a solid high performing scale-out storage system and add a layer of very high performance caching into the server (VM host or application server). Gives a great best of both worlds solution.
