Re: [ceph-users] Bluestore Hardwaresetup

2018-02-16 Thread Jan Peters 

Hi,
 
thank you.
 
Networksetup is like that:
 
2 x 10 GBit LACP for public
2 x 10 GBit LACP for clusternetwork
1 x 1 GBit for management 
Yes Joe, the sizing for block.db and blockwal would be interesting!
 
Is there another advice for SSDs like blog from Sebastian Han?:

I have a question about  block.db and block.wal
 
How big should they be?
Relative to drive size or ssd size ?
 
Thanks Joe

Peter;

I was just looking at this myself.
With regards to BlueStore, the Config Reference is useful:
http://docs.ceph.com/docs/master/rados/configuration/bluestore-config-ref/

As far as tiering goes, the OSD Config Reference talks about it:
http://docs.ceph.com/docs/master/rados/configuration/osd-config-ref/

The following talks extensively about tiering, and recommends not doing it:
http://docs.ceph.com/docs/master/rados/operations/cache-tiering/

Subject: [ceph-users] Bluestore Hardwaresetup

Hi everybody,

I want to evaluate ceph with bluestore, so I need some hardware/configure 
advices from you. 

My Setup should be:

3 Nodes Cluster, on each with:

- Intel Gold Processor SP 5118, 12 core / 2.30Ghz
- 64GB RAM
- 6 x 7,2k, 4 TB SAS
- 2 x SSDs, 480GB

On the POSIX FS you have to set your journal on SSDs. What is the best way for 
bluestore? 

Should I configure separate SSDs for block.db and block.wal?

Is there a way to use CacheTiering or a cachepool? 

Thanks in advance

Peter
