[Openstack] swift and two data-centres - hierarchical zones?

2012-03-10 Thread John Leach
Hi, I'm looking at deploying swift across two data-centres - I'd like to write 3 replicas: two in one data-centre and the third in the other another (doesn't matter which way around). I'd like to be able to tolerate the failure of (or loss of connectivity to) either data centre. If I create one

Re: [Openstack] [CHEF] How to structure upstream OpenStack cookbooks?

I like where this discussion is going. So I'd like to throw a couple more sticks into the fire, around test/SAIO vs production deployments.. * Swift cookbooks (and in general) should not assume control of system side resources, but rather use the appropriate cookbook (or better yet definition if

Having more than 5 companies pony up big dollars *is* a great problem to have. I didn't mean to suggest the solution stays the same. We need to plan for this scenario as there is a real chance of more participants than what has been negotiated in the back rooms. Of course, everyone wants the

2012-03-10 Thread Joe Gordon
Paulo, Caitlin, Can SHA-1 collisions be generated? If so can you point me to the article? Also why compare hashes in the first place? Linux 'Kenel Samepage Merging', which does page deduplication for KVM, does a full compare to be safe [1]. Even if collisions can't be generated, what are the

Re: [Openstack] Enabling data deduplication on Swift

2012-03-10 Thread Maru Newby
Hi Joe, There's one huge difference between page deduplication and object deduplication: Page size is small and predictable, whereas object size is not. Given this, full compares would not be a good way to implement performant object deduplication in swift. Thanks, Maru On 2012-03-10, at

Maybe a happy path exists, between efficiency and correctness ;) I think the Rsync is probably a good comparison to the use case at hand (it identifies identical blocks between the source and target, and only sends deltas of the wire). It combines a quick has to identify candidates that might be

Re: [Openstack] Enabling data deduplication on Swift

2012-03-10 Thread Maru Newby
Ah, right. I'm sorry to say I hadn't TFA yet and wasn't thinking of block-level deduplication. But though block-level compares might be possible, the distributed nature of swift would likely make this quite complicated. It might make sense for KVM to compare memory pages, but I imagine that
