This is no coincidence. Ceph comes out of technology developed at Dreamhost.

Ceph is through and through Sage's work, it wouldn't exist without him.
I really didn't see it coming, but now that it happened I'm kind of glad.
RH is one of the few corps who still has credibility and good karma. CEPH will be in good hands.

I would love to hear people's opinion's on what this means for ceph going forward? Will it change anything?
It's telling for me that as the project starts becoming 'hot' RedHat step in. I totally get why it's a great strategic purchase in the context of winning cloud adoption / share / love.

IMHO, the biggest thing will be that Ceph is now a product that is supported by a huge publicly traded company. That's a big deal and I'll explain why:
Storage is precious data is a big responsibility within most IT orgs. There are lots of regulations and best practices when it comes to protecting, backup up, verifying, and making available business records that are stored digitally. A Fortune 500 company isn't going to trust their business to a home grown solution (think self-supported Ceph compiled from source) when they can pay experts to do that work.
So, in the marketplace, Ceph competes against Scale-IO (now EMC) and Cleversafe. Scale-IO is on CTO radar because it's supported and sold by EMC. Even if Ceph is FREE it doesn't matter because you need support for these products to be actually deployable.
SO...I'm sure that the Inktank acquisition was predicated on a couple of things:
1. Potential customers saying that they liked Ceph but had problems getting it past management because Inktank was too small.
2. RedHat understanding (and verifying) that there is a huge opportunity in storage management and they were tired of getting frozen out by other solutions that were better supported.

This most likely means that more engineers will be working on it and RedHat's legendary QA will be running Ceph through it's paces.
For Ceph, this is only a good thing. Redhat's trackrecord for this type of thing is very good.

There are some closed source bits which will be open sourced. Search for "Calamari" in the press release:

I'm more interested in what it means for Gluster. I've had RH pushing Gluster at me very hard as performance-competitive with Ceph. Now they have Gluster and Ceph, it'll be interesting to see if Gluster falls by the wayside, or if they reposition Gluster more as easily-configured resilient storage.
The press release de-emphasized CephFS, and bumped XFS while ignoring Ceph's BTRFS mode (where snapshotting is available).
CephFS (which is a distributed file system) is orthogonal to XFS or BTRFS which are local file systems. Since Gluster is providing a file system solution at this point, that may be the reason for the de-emphasis. However, Gluster is not a parallel file system, and Ceph is much better suited to fill that role. So I suspect CephFS will continue to be developed, if anything to compete against Lustre, PanFS, GPFS, etc..
That's because (a) CephFS isn't ready for prime-time (according to every talk I've seen at linux.conf.au in the last two years) and (b) the early push for btrfs as the underlying storage for Ceph has faded in favour of XFS until they're happier with the state of btrfs.
I would really appreciate if somebody can clear this up for me:
Can one mount Ceph on multiple nodes? (I'm referring to the CephFS part).
I've worked with OCFS2 (which allows you to do exactly this) and liked it very much, but would've loved a clustered backing storage. Which is what Ceph provides.

Theoretically yes, but do note CephFS is not considered "production ready" AFAIK.
GlusterFS is much more focused on the filesystem bit, so why not give that a try, too?

I think this is a clear play at driving some of the key components in the OpenStack world, with GlusterFS (subject of an earlier Red Hat acquisition) and Ceph being the two main distributed storage choices.
i somehow ended up at inktank's vegas launch party (i was pulled onto a bus while very drunk) and they were a really really nice group of people.
Fun fact - Sage was also the founder of webring, and simultaneously one of the dream host founders.
