Hello Discuss, I'd appreciate any comments on the following situation:
A large, dual quad-core Intel 5500 CPU system Storage: 6 2 terabypte drives, in a RAID 1+0 setup. Raid controlled by controller card. Total available storage is about 5.5 terabytes. The drives are 7200 RPM OS drive: 2 160 gig drives in a RAID 1 setup, software controlled OS: CentOS 5.4 Virtualizatoni: KVM Virtual environments: Ubuntu 8.04 or 10.04 Each virtual system will have a relatively small partition to boot from. The data partition (/var) will be accessed via either NFS or CIFS. The exported filesystems will be on the CentOS server, and exported to each individual virtual system. Each virtual system will access a different exported directory Each virtual system will be running PostGresql 8.2/8.3/8.4. In addition to the database, they also store 50-100 k images So, here are my questions: 1. Which is better for performance, NFS or CIFS? 2. What would be the best filesystem to store all the export directories on? 3. Would it matter if the file system data uses a different virtual interface than the primary interface? 4. How would you mirror the NFS volume to a second system?
