Hi everyone, I am currently looking into different storage solutions for the infrastructure I am working on. The main usage would be slow storage of images, archives and maybe later logs. Map/Reduce jobs are a bonus and not a requirement. Since our current infrastructure is running on SDC7 I naturally thought about Manta. Other alternatives being Riak S2 or Swift. The fact that Manta is not oriented toward any specific type/size of files is a good selling point for me.
The current infrastructure is limited to 1 Rack of around 15 CNs in one Datacenter. We have plans to extend to multiple racks and at least two other Datacenters. I currently have 4 CNs and 3~4 SNs available. One of the 4 SNs is the current SDC Headnode which means that I could do something like: 1) using 2CNs to setup a HA headnode. The 2CNs left being used for Manta with 2 Metadata shards. This would free one SN and let me with 4SNs for Manta. 2) keeping my Headnode where it is and using the 4 CNs + 3 SNs for Manta with a number of shards to define. 3) buying more CNs/SNs. As explained before I am primarily looking for storage. My main concern is keeping as much flexibility as possible for future growth/expansion and raw performance doesn't really matter. My questions are: How many shards should I start with ? How many CNs / SNs would you recommend (cf solution 1, 2, 3 or others) ? >From there which zone layout would you recommend ? Manta documentation <https://github.com/joyent/manta/blob/master/docs/manta-ops.md#planning-a-manta-deployment> is pretty detailed but unfortunately more oriented toward infrastructure with a fixed number of Datacenter, Racks, etc... Manta seems to have the flexibility and potential to be easily expansion, following an infrastructure growth, but I missed any example of it in the documentation. ------------------------------------------- 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
