Solaris

Hello All,

I have small doubt. It's related to SVM in solaris 10. I have created raid 0 (striping) using 3 slices of 500 MB size (default interlace value as 32KB)

d2: Concat/Stripe ---- Interlace value is 32 KB
Size: 2923830 blocks (1.4 GB)
Stripe 0: (interlace: 64 blocks)
Device Start Block Dbase Reloc
c0d0s3 48195 Yes Yes
c0d0s4 48195 Yes Yes
c0d0s5 48195 Yes Yes

I have created another raid 0 striping with interlace value as 16MB

d2: Concat/Stripe
Size: 2843505 blocks (1.4 GB)
Stripe 0: (interlace: 32768 blocks)
Device Start Block Dbase Reloc
c0d0s3 48195 Yes Yes
c0d0s4 48195 Yes Yes
c0d0s5 48195 Yes Yes

I am not able to understand the fundamental behind the block's variation in case of size and stripe. Could anyone of you please help me with this.

Thx

An interlace is the size, in Kbytes, Mbytes, or blocks, of the logical data segments on a stripe. Depending on the application, different interlace values can increase performance for your configuration. The performance increase comes from having several disk arms doing I/O. When the I/O request is larger than the interlace size, you might get better performance.
