Hi,
I've been doing some numbers today and it looks like our choice is
between 6 x R515's or 6 x R410's depending upon whether we want to allow
for the possibility of adding more OSDs at a later date.
Yeah, tough call. I would expect that R410s
Hi,
I'm looking to purchase a production cluster of 3 Dell Poweredge R515's
which I intend to run in 3 x replication. I've opted for the following
configuration;
2 x 6 core processors
32Gb RAM
H700 controller (1Gb cache)
2 x SAS OS disks (in RAID1)
2 x 1Gb ethernet (bonded for cluster
Hi,
I'd be interested to hear from anyone running a similar configuration
I'm running a somewhat similar configuration here. I'm wondering why you
have left out SSDs for the journals?
I gather they would be quite important to achieve a level of performance
for hosting 100 virtual machines
FWIW, here is what I have for my ceph cluster:
4 x HP DL 180 G6
12Gb RAM
P411 with 512MB Battery Backed Cache
10GigE
4 HP MSA 60's with 12 x 1TB 7.2k SAS and SATA drives (bought at different times
so there is a mix)
2 HP D2600 with 12 x 3TB 7.2k SAS Drives
I'm currently running 79 qemu/kvm vm's

I can't go into exact prices due to our NDA, but I can say that getting
a couple of decent SSD disks from Dell will increase the cost per server
by a four figure sum, and we're

Hi,
With so few disks and the inability to do 10GbE, you may want to
consider doing something like 5-6 R410s or R415s and just using the
on-board controller with a couple of SATA disks and 1 SSD for the
journal. That should give you better aggregate performance since in
your case you

If I currently understand idea, when this 1 SSD will fail whole node

Only OSDs that use that SSD for the journal will fail as they will lose
any writes still in the journal. If I only have 2 OSDs
Hi,
Here's a quick performance display with various block sizes on a host
with 1 public 1Gbe link and 1 1Gbe link on the same vlan as the ceph
cluster.
Thanks for taking the time to look into this for me, I'll compare it
with my existing set-up in the morning.
Thanks,
