How to improve IO of Solaris machine
Hello,
I want to improve IO of T5220 solaris 10 (sparc) machine. Can anybody please help me to do that?
IO of T5220 seems to be very slow as compared to other machines. if anybody can help me out to tune this architecture to have efficient IO.

how many disks do you have in that machine and what application? What is the memory size?
ASKER
It has two disks. One is having ZFS and other is having UFS. each disk is of 200GB. RAM is of 32GB with 64 CPUs.
what application do you run and why you think io needs improvement?
ASKER
i running postgres and doing bulk copy.
i am inserting huge data into the database. currently, i am getting 30K inserts/sec...whereas, i want to achieve 2 Millions inserts/sec.
'zpool iostat' is showing write speed of 1.2M/sec.

If you have such a requirement, then it is recommended to have external storage with multiple disks where you can distribute your database files for better read / write performance.

Thanks all for providing valuable information.
Yes, you guys are right that i would need to check for external storage or ZFS with more disk for distributed IO.

The "Sun Storage 7110 Unified Storage System" is a very nice system for a reasonable price :-)

I would state that adequate answers were provided by the experts and propose to split points amongst the participants.
Holy 2009 question.
I think a blunt assessment following disclosure of single "disk" setup does not lend itself to Avail opportunity to enhance ?I/O pergormance.

I agree with arnold that the two linked comments by arnold and myself are an adequate answer to the question.
