Start with this:

Pay close attention to the 3610 SSDs, while slightly more expensive they
offer 10 times the endurance.
Guestimate the amount of data
Now, I've never setup a journal on a separate disk, I assume you have 4
partitions at 10GB / partition, I noticed in the docs they referred to 10
GB, as a good starter. Would it be better to have 4 partitions @ 10g ea or
4 @20?
I know I'll take a speed hit, but unless I can get my work to buy

Hi Christian,
I didn't create the partitions beforehand, which is probably the reason why we
had differing outcomes.
The actual partitions were fine, I could mount the root partition from a live
cd. However when the server tried to boot it never loaded grub, it just sat
there with a blinking

simple messenger is the classic messenger protocol used since the begining of
ceph.
xio messenger is for rdma (infiniband or Roce over ethernet)
they are also a new async messenger.
They should help to reduce latencies (and also

Here a log file from one of the OSD that is flapping. Would appreciate any help
in getting back a stable CEPH cluster.
There are 3

Well, although I have 7 now per node, you make a good point and I'm in a
position where I can either increase to 8 and split 4/4 and have 2 ssds, or
reduce to 5 and use a single osd per node (the system is not in production
yet).
Do all the DC lines have caps in them or just the DC s line?

I would not use a single ssd for 5 osds. I would recommend the 3-4 osds max per
ssd or you will get the bottleneck on the ssd side.
I've had a reasonable experience with Intel 520 ssds (which are not produced
anymore). I've found Samsung 840 Pro to be horrible!
Otherwise, it seems that
Ok, any size suggestion? Can I get a 120 and be ok? I see I can get
DCS3500 120GB for within $120/drive so it's possible to get 6 of them...

I am not sure about the enterprise grade and underprovisioning, but for the
Intel 520s i've got 240gbs (the speeds of 240 is a bit better than 120s). and
i've left 50% underprovisioned. I've got 10GB for journals and I am using 4
osds per ssd.
