Calors, Thank for your answer.
The GlusterFS will be presented using NFS through a 10g network to a farm of KVM servers managed by Cloudstack. I need space (1T hdd) and redundancy (GlusterFS) and want to have two disk offer (standard and faster) hug -----Message initial----- De:Carlos Capriotti <[email protected]> Envoyé:mar. 25-03-2014 19:10 Sujet:Re: [Gluster-users] Build disk tiering offer with GlusterFS À:Hugues Lepesant <[email protected]>; Cc:[email protected]; Hugues: I tend to agree with you with your disk setting for system. I have that myself and it is rock solid, and lightning fast. For your 11 x 1 To (tera octets, uh ? The French way), I'd tend to agree, because these 7.2 Krpm disks feel a bit slow, but for the 11x600 GB 15 Krpm... I think that will be a waste of diskspace. That is my IMPRESSION anyway, based on my similar 10x300 GB 10K rpm (PE2900 with PERC 5/i). This setting can peak 800 MBytes/second, and my worst reading with it are around 400 MBytes/s. So, you can easily saturate regular network cards, in theory (1 Gbps), or at least, have a very decent data stream with 10 Gbps. My suggestion: install a quick test system with very basic tools on your 146 GB raid1 volume, just to be quick and do NOT include the data raid volumes. Next, make performance tests with each variation, RAID 5, RAID6 (if you have it), and RAID50, with both disk sets. Well, supposing of course you have the the hardware available, which sounds you have.
