I have installed and test Ceph on VMs before, i know a bit about configuration and install. Now i want to use physic PC Server to install Ceph and do some Test, i think the prefermance will better than VMs. I have some question about how to plan the ceph storage architecture. >>> what do i have as below: 1. only one Intel SSD 520 120G, plan used for Ceph journal, to speed the Ceph prefermance. 2. some old PC Server with Array Controller, include 4 x 300G SAS HDD 3. Gigabit Switch >>> what do i plan: 1. Ceph cluster such as: A: osd+mon, B: osd+mon , two PC server Ceph cluster 2. the only one SSD install on A, use for Ceph journal 3. use Nic bind(LACP) on Server, and Switch port configure LACP 4. i plan to use Debian 7 testing >>> what shall i ask: 1. shall i use Array controller config Raid or not ? or how to use the HDD better, use HDD directly, no need raid ? 2. i have only one SSD HDD for journal, so what shall i modify in my plan ?? and how to config journal to SSD ? hope some one can give me some guide. Many thanks in advanced. -------------- next part -------------- An HTML attachment was scrubbed...
