Thanks to Andy Crichton, Brett Lanham, Kevin Buterbaugh, Christophe Dupre, John Eisenschmidt for respionces and I appologize for the delay. A couple of themes: 22G s a big /var. this is true, but I've had problems with all the systems I have for /var running out of space and this server is going to use a lot of /var space, so I'm going to allocate it while I have it. Also, it will be connected to a EMC FC4700 SAN, so the internal drives (6x72G) are not going to be needed for applications and data. Use it if you have it. Don't RAID5 a database. Agreed. Parity uses enough CPU to slow things down. And If I don't show performance improvement, I'm not likely to get more budget approved for anything. RAID 1+0 for the database. Use the available number of slices. Maked ufsdump easier, filling / causes a system to hang, managing growth would be easier. I used: /dev/dsk/c1t0d0s0 1233679 101570 1070426 9% / /dev/dsk/c1t0d0s4 7516781 1130618 6310996 16% /usr /dev/dsk/c1t0d0s5 17539178 8342565 9021222 49% /opt /dev/dsk/c1t0d0s6 7566893 36790 7454435 1% /export /dev/dsk/c1t0d0s7 20044777 126056 19718274 1% /var with slice 1 for swap slice 2 left as backup slice 3 for metadb for SDS Drives 2 an 4 have been given to my DBA and drives 1,3 and 5 for the RAID mirrors. Q1 purchase of a pair fo SAN switches will connect this to my EMC FC4700 and the database will move there then. Then I'll have 6x72G for the OS. =) There should be some swap. Opinions varied, from RAM size to 2-4 times RAM. With the drive space available now, I went with 2x RAM. -- Kevin Metzger Systems Administrator Progressive Medical, Inc.

I plan on leaving 4 HDDs for my DBA to load Oracle later -(SVM raid 5). I plan on mirroring my OS disk leaving me one 72G drive to play -with. I remember reading that leaving a 100M slice at the beginning for SVM. -I have read lately that Sun is leaning to fewer large slices instead of -more smaller. So, my plan is: - -/svm 100m -/ 50G -/var 22G - -Also, thoughts about making a smaller than twice mem size swap? I'm planning -on 8G swap since I will have the disk space right now. - -Thanks, and I'll summarize - --- -Kevin Metzger -Systems Administrator -Progressive Medical, Inc. -_______________________________________________ -sunmanagers mailing list -sunmanagers@sunmanagers.org -http://www.sunmanagers.org/mailman/listinfo/sunmanagers - _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Mon Jan 6 10:39:47 2003
