Indeed, there is some work already going in this direction for OpenStack
Object Storage. A couple of Red Hat engineers are working on  LFS, Local
File System (https://github.com/zaitcev/swift-lfs and
http://zaitcev.livejournal.com/215159.html, plus there is something in
review on review.openstack.org, too) to allow swift to better integrate
with different filesystems.

Something like LFS was originally proposed by Nexenta a while back but
their patch unfortunately never merged.

LFS was mentioned on swiftstack blog after the summit in Portland.

Re: [Openstack] why did openstack choose ceph (and not glusterfs)

2013-07-12 Thread Patrick McGarry 
Hey all,

Ceph community manager here.  Just to be clear, while a lot of OpenStack
implementations are "choosing Ceph," there are plenty that aren't.  That's
the beauty of OpenStack, especially as it relates to Cinder and Glance.
 It's very easy to plug in whatever makes the most sense for your
particular use case.

In fact, we'd love to see a similar abstracted approach on the object
storage side as well.  While Ceph supports the Swift API, there are many
other tools that might not.  We are huge fans of choice, and we'd love to
see the ability to easily plug options for object as well as block.

Hope that clears things up a bit and you are able to choose the tool that
best suits your needs.  Obviously we think Ceph is amazing, but we're all
FOSS heads and are pretty happy as long as you find an Open Source solution
that does what you need.

Shout if you have questions.

Patrick McGarry

 frankly I don't care (sorry etiquette) since it will resolve a
 reasonable question that isn't clearly answered on the web.

 Why did openstack choose ceph and not glusterfs. There doesn't seem to
 be a lot of (good) information on how/why to choose one over the other,
 and I'm sure most folks do a proof-of-concept to figure this out, but it
 doesn't seem like a lot of information has been shared on the matter.

 That being said, OpenStack is a large open source project that has
 decided to use this storage platform (big decision). Why and how did the
 technical architects for OpenStack come to this decision (blog post
 would be awesome, wasn't able to find one Googling).

Haomai, Zippy,

Do you have any actual link to share about where your impression is from?
I don't want to be the last to know that we _choose_ something.

Hi,

I think the information "OpenStack choose Ceph" is from Ceph community,  we can 
often heard about correlative talks from
Ceph community and blogs.  There is a illusion that OpenStack decide to choose 
Ceph as backend.

Hi Zippy,

To be clear, OpenStack doesn't really "choose" at all.  In terms of Cinder
you have a choice, that could be the base LVM implementation, Ceph-RBD,
Gluster or any choice from a long list of supported/integrated backend
storage devices.
