comment MyISAM Throughput spike at 12000 record insert
1 thread is where MyISAM shines, since there is no contention. InnoDB being an ACID-compliant engine needs to write more data to achieve that reliability than MyISAM does. If your benchmark had 50 threads you'd see the exact opposite performance (due to MyISAM locking the entire table).

comment MyISAM Throughput spike at 12000 record insert
I'm not sure why you have the expectation that the performance between the two should be similar. They shouldn't. Without knowing how the tool you're using to do does the inserts, my guess is that it's using multiple threads to achieve that high level of throughput. MyISAM does not support multiple concurrent writes to the same table, InnoDB does. One row being updated in a MyISAM table locks the entire table. InnoDB just locks the rows.

Any idea about this? You bought the wrong gear without checking what you needed first. Are you asking why the original drive has a different interface? Yeah.. what @joeqwerty said: Are you serious?

comment How to add a partition to CentOS without losing data on it
As you said at the beginning, /dev/cciss/c0d1 is the full device, c0d1p1 and c0d1p2 are the partitions. Then you show the output of running fsck on /dev/cciss/c0d1 (which as you know is not a partition). Since filesystems tend to be on partitions, you need to run fsck (file system consistency check) against c0d1p1/p2, not the c0d1 device.

comment Bind9 on Ubuntu - SERVFAIL
Your netstat shows it's bound to 172.30.1.115:53 then you query localhost. It's not bound to 127.0.0.1:53. It's failing because there's no server listening there.

comment Reducing query cache for mostly INSERT-heavy database?
You should use the one that performs the best when you benchmark a realistic workload on it. That said, just turn the cache off. It adds overhead to every query while it goes through the code to check the cache.
