Replica Sets without Sharding

[igotux igotux]

Hello,

In my production setup, i'm planning to use 2 16G nodes with 750GB disk space as Replica Sets and one small node as arbiter ( Total 3 nodes ). My data will grow around 500G. I'm not planning to use any sharding here. Do you guys see any problems on this design ?

Thanks for your inputs,

Hi Arwin,do not you think 750G disc space is a little not enough for 500G data?Index,oplog and journal log will take up a lot of space,have you taken all these into account?

Hi,

Your general set up sounds standard (replica set with two nodes and an arbiter) but you'll want to upgrade your disk space before you grow to 500Gb data used of 750Gb total.

The limited amount of free space relative to your data size will be an issue if you want to do a backup or repair of your database.

Cheers,
Stephen

Do u plan to purge or backup data regularly to keep the data size to be around 500G?
