Can you tell me the total capability of your glusterfs, and how many
disks each node has? And your cluster's speed？-----邮件原件----- 发件人: [email protected] [mailto:[email protected]] 代表 Nathan Stratton 发送时间: 2012年2月17日 22:35 收件人: Song 抄送: [email protected]; 'Andrew Holway' 主题: Re: [Gluster-users] >1PB On Fri, 17 Feb 2012, Song wrote: > Hi, > > We have the same question.

Gluster can easily support a large number of nodes, the question is how much you care about the underlying data. We store 2 copies of the data and our underlying hardware is RAID6 allowing us to lose 2 disks on each server. As the number of nodes grows that chance of losing a node becomes higher, but one of the beautiful things about Gluster is you still have access to all the other data that is NOT on the lost pair of servers. We have found that your best bet is to split the data over as many servers as possible provides the best up time. ><> Nathan Stratton CTO, BlinkMind, Inc. nathan at robotics.net nathan at blinkmind.com http://www.robotics.net http://www.blinkmind.com _______________________________________________ Gluster-users mailing list [email protected] http://gluster.org/cgi-bin/mailman/listinfo/gluster-users _______________________________________________ Gluster-users mailing list [email protected] http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
