Subject: [9fans] Remus: High Availability via Asynchronous Virtual Machine Replication
Date: Thu, 3 Dec 2009 12:11:05 -0800 [thread overview]
Message-ID: <e763acc10912031211y6c60b0f8ld5248c023671302b@mail.gmail.com> (raw)
This appears to be an interesting way of solving an HA problem:
http://nss.cs.ubc.ca/remus/papers/remus-nsdi08.pdf
It is also different from a typical approach of checkpointing in HPC.
One thing that I'm wondering about though is whether Plan9 architecture
of things like /net and /dev/sd would actually allow it to be HAed in that
fashion *without* a help of the hypervisor.
Does it make sense or am I totally off base here?
Thanks,
Roman.
