I am Sandeep from an Animation and Visual effects studio called as GoldenEye. We have a very unstructured data which needs some data replication but in reality the requirement is scaling up and at the same time replication is somewhat tougher so we are using the " Allway sync" software to sync the folders from time to time worrying about the data server failure.. now when I saw Gluster I just got an idea about the Isilon storage. I have few doubts which will make me to use gluster at my studio. 1. If I got a storage cluster with 6 storage servers with mirror option enabled and now what is the performance? 6x? or 2x? 2. and what if a node fail? does the data resides on the other one? 3. using stripe on 6 servers means usable space is just 1 server space? and performance is 6x ? I have too much of data which will be sucking by the renderfarm and my desktop users always complain that the servers are slower but still we have Hitachi 2TB deskstar 7200rpm which sends 130MB/sec per disk but now I have such a requirement where I want 400MB/sec for one editing machine and 600MB/sec for the renderfarm and another 400MB/sec for the deskstop users all simultaneously and under the same name space...huh... I believe gluster can help me in doing this... I have setup gluster with onboard Gigabit Lan for Asus M2n68am motherboard but its unable to connect... I was very very impressed with gluster technology but unable to test it... But I have few questions... what to do in order to get that speed on my servers? 1. I want to use 4 machines with 4 1Gbps Intel dual port two cards per system and 4 Hitachi 130MB/sec hard disk 2TB each drive ( 8TB in total per system ) want to use it in STRIPE config since its looking for performance intensive ... But what about the usable space? will it become my question is do i get 16Gbps of throughput for one file ( atleast according to the calculation ) do I need to use stripe? what will be the performance if i use 6 sata port motherboard with 6 HDD do I get the performance of raid 0? can you please help me out about my config? regards, sandeep
