Perhaps start at https://github.com/joyent/sdc/blob/master/docs/developer-guide/architecture.md and https://github.com/joyent/manta/blob/master/docs/manta-ops.md. There are additional documents in these repositories, especially the sdc repo (see all of /docs). Each component also has API documentation, which covers the private implementation details of SDC; each should have a docs/ directory. There's also additional information intended mainly for operators at https://docs.joyent.com/sdc7 which does nevertheless have some architectural information along with a lot of examples. > One question that I'm particularly interested in is how they address > high-availability issues - storage redundancy, failover, that sort of > thing.

Manta's HA architecture is discussed in some detail by Dave Pacheco, one of the core Manta architects, at http://dtrace.org/blogs/dap/2013/07/03/fault-tolerance-in-manta/. The documentation also goes into some detail on how this is achieved; see also the Manatee documentation at https://github.com/joyent/manatee/tree/master/docs as that component is central to availability. I'm not sure what you mean about ZFS. Everything in the entire stack is ZFS with the exception of the ramdisk image the OS boots from, and ZFS is central to making Manta's compute functionality fast and reliable. I wrote a little bit about storage in Manta at http://dtrace.org/blogs/wesolows/2013/06/25/manta-what-lies-beneath/. Did you have a specific question there? ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
