Re: [ceph-users] SSD question

Hi, Plus reads will still come from your non-SSD disks unless you're using something like flashcache in front and as Greg said, having much more IOPS available for your db often makes a difference (depending on load, usage etc ofc). We're using Samsung Pro 840 256GB pretty much like Martin

[ceph-users] RBD Windows Failover Clustering

Hi, I was wondering if anyone has had any experience in attempting to use a RBD volume as a clustered drive in Windows Failover Clustering? I'm getting the impression that it won't work since it needs to be either an iSCSI LUN or a SCSI LUN. Thanks, Damien

For the time being, you can install the Raring debs on Saucy without issue. echo deb http://ceph.com/debian-dumpling/ raring main | sudo tee /etc/apt/sources.list.d/ceph.list I'd also like to register a +1 request for official builds targeted at Saucy. Cheers, Mike On 10/22/2013 11:42

And a +1 from me as well. It would appear that ubuntu has picked up the 0.67.4 source and included a build of it in their official repo, so you may be able to get by until the next point release with those. http://packages.ubuntu.com/search?keywords=ceph On Oct 22, 2013, at 11:46 AM, Mike
