RE: Docs, Links, Good Books on Performance with RAC 10.2 / Solaris 10 ? ....... Veritas CFS(SFRAC) or QFS ? which FS to choose for RAC Benchmark ?

Tim Gorman, to my impression, seemed to favor Veritas over QFS as per
the following Link:-

 

http://www.freelists.org/archives/oracle-l/05-2005/msg01257.html

 

Tim - your current views please on Veritas SFRAC 4.1/5.0  versus Sun QFS
? if possible.

 

Thanks indeed

Thanks so much Anjo for the support.

 

For the upcoming Benchmark with Solaris 10/RAC Oracle 10.2, we need to
define the "File system" setup. 

 

Seek your advice on the following:-

 

Qs 1 Is QFS Certified for Solaris 10/Oracle RAC 10.2? Seemingly it has
been certified last year for Oracle 9i.

 

Qs 2 Which is advisable - Veritas CFS (SFRAC) or Sun QFS? 

 

(i) Does QFS support Low Latency Protocol (LLT) or the default User
Datagram Protocol (UDP) only?

NOTE - Veritas CFS (SFRAC) does support LLT.

 

(ii)) Is QFS in use at Large Production RAC 10g Sites?

 

(iii) Do both QFS & Veritas CFS(SFRAC) support Concurrent IO [CIO] i.e.
multiple threads can simultaneously perform reads and writes on a shared
file? 

NOTE - CIO is available with JFS2 Filesystem from AIX.

 

 Qs 3 What is the Effort needed to switch from Veritas CFS(SFRAC 4.1 or
5.0{if certified too}) to QFS & vice-versa by using a baseline UFS
database in case of Bugs/performance issues on either?

 

NOTE - RAW, ASM are being avoided for now.

 

Thanks indeed

 

Vivek

Well you could talk to me :-)

 

I did a 15K user RAC/OPS once.
