Hello again... Now that I've got my 2540 up and running. I'm considering which configuration is best. I have a proposed config and wanted your opinions and comments on it.
Background.... I have a requirement to host syslog data from approx 30 servers. Currently the data is about 3.5TB in size spread across several servers. The end game is to have the data in one location with some redundancy built-in. I have a SUN 2540 Disk Array with 12 1 TB (931GB metric) drives connected to a SUN T5220 server (32GB RAM). My plan was to maximize useable space on the disk array by creating each disk as a volume (LUN) and having ZFS on the server raidz 11 drives and then adding the 12th drive as a spare. We have SUN service contracts in place to replace drives as soon as they go down. With this config, I have a single zpool showing 9.06 T available. Now questions..... 1) I didn't do raid2 because I didn't want to lose the space. Is this a bas idea?? 2) I did only one vdev (all 11 LUNs) and added the spare. Would it be better to break this up in to 2 vdevs (one w/ 6 LUNs and the other w/ 5)?? Why? 3) I have intentionally skipped the hardware hotspare and RAID methods. Is this a good idea?? What would be the best method to intergrate both hardware and software 4) A fellow admin here voiced concern with having ZFS handle the spare and raid functions. Specifically that the overhead processing would affect performance. Does anyone have experiance with server performance in this manner? 5) If I wanted to add an additional disk tray in the near future (12 more 1TB disk), what would be the recommended method? I was thinking of simply createing additional vdevs and adding them to the zpool. Thanks in advance for the discussions!!
