Hi flexi,
Firstly , we must know the your hardware system ?
Maybe we can determine best choice for your needs to that.
if your system x86 arch maybe you can try "LSI or other Logic Configuration Utility Console " which appears in the boot stages..
You assume 8 disks , but has your system contains these from local or san ?
if your all disks has local ( SAS / Sata .. ) , then what is the your critical data ? ( database )
all disks are at the same or size ?
Yes , Raid5 can be good choice or maybe not for avaliable disk space or security requirements.
That can change to your needs.
For exa : you want to create hard raid 5 vol with 6 disks at size 300 GB. ( security : with "1 disk" failure )
then your avaliable space ( n x size -1 x size ) = 6 x 300 - 1 x 300 ( for total parity size ) = 1500 GB
So at the reality , what is your systems for solaris ( oracle sparc / x86 / non-oracle x86 .. )
in Sparc systems LSI raid controllers does not support for raid 5
if you will be use zfs , then you can use software raid with zfs ( zpool )
For exa :
Now i can say what i do with 6 disk in my sparc hardware.
* 4 disk for RAID 1E ( security two disk in teory but may be "one disk" to controller !! )
-----------------------------------------------------------------------------------------
( * You can create similiar this volume with your 6 disks )
( boot prompt )
* create 4 disk with RAID 1E volume ( vol1 ) --> For your database pool
* After apply this , check volume :
---------------------------------------
* If raid volume is "inactive" state then starts
-> Now first Raid volume ( vol1 ) is Ready..
2-) The other 2 disk with RAID1 ( via the other Raid Controller port )
* Select the disk and create hard raid.
....
....
-> Now first Raid volume ( vol2 ) is Ready..
* Raid operations completed..
* I installed the Solaris OS on the this volume ( vol2 ) at the Disk Select Menu..
* when system is on :
vol2 ( in 2 disk with size 559 with RAID 1 ) ---> 2 X 559 /2 = 556 GB in OS
----------------------------------------------
note : my raid LSI controller(s) does not support other raid levels ( eg : raid5.. )
Hi;
Can someone please explain how do connections differ from threads? or a link to a good site about connection pooling and how threads are utilized by the OS.

hi,
i am looking for a tool to see how many CPUs, controlled by FSS inside a pool, a project used over some time....
i have a 20k with several zones inside some pools. the cpu-sets/pools are configured with FSS and the zones with different shares. Inside the zones, i use projects with FSS... (2 Replies)
I created a pool the other day. I created a 10 gig files just for a test, then deleted it.
I proceeded to create a few files systems. But for some reason the pool shows 10% full, but the files systems are both at 1%? Both files systems share the same pool.
When I ls -al the pool I just... (6 Replies)
I need to migrate an existing raidz pool to a new raidz pool with larger disks. I need the mount points and attributes to migrate as well. What is the best procedure to accomplish this. The current pool is 6x36GB disks 202GB capacity and I am migrating to 5x 72GB disks 340GB capacity. (2 Replies)

Hi!
I would also like to know if I need first to create a pool before I can mirror my disks inside that pool.
My first disk is c7t0d0s0 and my second disk is c7t2d0s0 as seen in the figure below.
I would create a pool named rpool1 for this 2 disks.

I am trying to test simple zfs functionality on a FreeBSD 8.2 VM. When I try to run a 'zpool create' I receive the following error:

I have a single zpool with 3 2-way mirrors ( 3 x 2 way vdevs) it has a degraded disk in mirror-2, I know I can suffer a single drive failure, but looking at this how many drive failures can this suffer before it is no good? On the face of it, I thought that I could lose a further 2 drives in each... (4 Replies)
Hi all,
I am trying out Solaris 11.3
Realize the option of -p when using beadm that i can actually create another boot environment on another pool.
