does anybody have some numbers on speed on sata vs 15k sas?
The next chance I get, I will do a comparison.
Is it really a big difference?
I noticed a huge improvement when I moved a virtualized pool
off a series of 7200 RPM SATA discs to even 10k SAS drives.

What I would really like to know is if it makes a big difference
comparing say 7200RPM drives in

For random io the number of IOPS is 1000/(mean access + avg rotational
latency) (in ms)
Avg rotational latency

If by 'huge' you mean much more than 10K/7.2K in the data path with otherwise
same number of spindles, then
that has got to be because of something not specified here.
No it doesn't. The response time on 10k drives is night and day better than
7.2k drives. VMware workloads look exactly like

I am looking at a nas software from nexenta, and after some initial testing i
like what i see. So i think we will find in funding the budget for a dual
setup.
We are looking at a dual cpu Supermicro server with about 32gb ram and 2 x250gb
OS disks, 21 x 1TB SATA disks, and 1 x 64gb SSD disk.

The system will use nexenta's auto-cdp which i think are based on
AVS to remote mirror to a system a few miles

Will the IOPS in the mirrored setup be so good, that a ssd cache
disk might not be needed? And i then might go for 10 x mirror with 2
x 1tb instead of 9? I really dont think that space will be an issue
This really depends on how many synchronous
