Hi to All,
I'm new to the Ceph community. I've found some used hardware on
our datacenter and i want to create a new Ceph cluster, a little bit
more powerful (i know that the disks are not good at all, each node
has 10 x 72GB SAS disks and 2 x 500GB SATA disks (that's not to much
space), but this is for testing the solution. The hardware is the
following:
OS Running: Ubuntu 12.10 Server 64 bits (on 2 x 140GB w/RAID-1)
ceph-node01(mon) 10.77.0.101 ProLiant BL460c G7 32GB 8
x 2 Ghz
ceph-node02(mon) 10.77.0.102 ProLiant BL460c G7 64GB 8
x 2 Ghz
ceph-node03(mon) 10.77.0.103 ProLiant BL460c G6 32GB 8
x 2 Ghz
ceph-node04 10.77.0.104 ProLiant BL460c G7 32GB
8 x 2 Ghz
ceph-node05(deploy) 10.77.0.105 ProLiant BL460c G6 32GB 8
x 2 Ghz
All the Blades are inside of the same enclosure so the connectivity is
going to be through the same SW (one cable) of 1Gb, i know that this
is NOT good at all but again is for testing, and is what we got for
the moment.
Could someone give me some hints on configured this hardware the Best
possible way? i mean where to put the Journals, how many OSD's per
node, i thought to use 2 x Journal disks in a 1:5 relation, so 1
journal for 5 OSD's. Is going to be better to use 2 x 72GB SAS disks
as the Journals right?, any other recommendations? Also when running
the "ceph-deploy new" command to create the cluster how can i specify
the name of the cluster?
Again sorry if they are very newbie questions but as i said im new to
Ceph.
Thanks in advance,
Best regards,
German Anders
