IOPS 측정하는 도구가 있었군.
내일 iSCSI 구성한 것 성능 체크좀 해봐야겠다.

P. 10 of Iometer guide:
The Edit Access Specification dialog shows you how the disk will be accessed. The default is 2-Kilobyte random I/Os with a mix of 67% reads and 33% writes, which represents a typical database workload. You can leave it alone or change it. Press OK to close the dialog when you are through.
For maximum throughput (Megabytes per second), try changing the Transfer Request Size to 64K, the Percent Read/Write Distribution to 100% Read, and the Percent Random/Sequential Distribution to 100% Sequential.
For the maximum I/O rate (I/O operations per second), try changing the Transfer Request Size to 512 bytes, the Percent Read/Write Distribution to 100% Read, and the Percent Random/Sequential Distribution to 100% Sequential.
