Thanks Wido, David and Christian, much appreciated! Regarding using SSD for OSD, I don’t want to spend any more so I will use the 2TB spinning disks, performance is not a huge issue. Ceph is overkill but I have the hardware lying around. It’s a small business, just a few users, no current file server, just google drive and apple time machine, I wouldn’t say I have any business critical storage requirements. It’s going to be slow, what does that mean, it will crawl, saving a 10MB file will take an hour, perhaps the combination of Atom CPU and spinning disks are a good marriage, 100MB/sec read/write for a large file would be amazing, half that would be fine, I would only expect 1 user to be reading/writing something big at any one time. Can’t I use a single DC S3700 for journal and cache tier? I’m about to decommission a Supermicro c2750 and so I could add that to the mix, could somebody please help me out with assigning the hardware and functions, I have a bunch of RAM sticks and could buy a few more: Node 1 - c2750(8c),4NIC,8GB,24GB,200GB - MDS, NFS Node 2 - c2550(4c),4NIC,8GB,24GB,200GB,2TB - OSD, Standby MDS, NFS Node 3 - c2550(4c),4NIC,4GB,24GB,200GB,2TB - OSD, MON Node 4 - c2550(4c),4NIC,4GB,24GB,200GB,2TB - OSD, MON Node 5 - c2550(4c),4NIC,4GB,24GB,200GB,2TB - OSD, MON I want to keep my power usage low and happy to do that at the expense of performance. With all the info provided is DRBD Pacemaker HA Cluster or even GlusterFS a better option? Thanks again.
