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.

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/sunmanagers
