Date posted: 22/01/2010 Intel and Microsoft, last week, discussed their iSCSI performance results in achieving 1 million IOPS on a two-socket desktop tower. According to Rick Coulson of Intel Corp, the secret behind this is having SSDs tightly coupled to a host in a highly tuned setup. Since SSDs are about 100 times faster in terms of latency than hard drives, there are some performance bottlenecks that need to be overcome. The physical interface along with the protocols, software driver, and the chipset interface all need to be optimized for performance. According to Coulson, by optimizing some parameters like, interrupts, driver software and the physical interface between the SSDs and the system we can expect to see gains in power and performance. The test setup consisted of a quad-core 3.2 GHz Xeon 5580 server running Windows Server 2008 R2. It was connected with an Intel X520-2 10 gigabyte Ethernet Server Adapter using the 82599EB controller. A Cisco switch fanned this out to 10 servers running iSCSI target software. A second configuration running Microsoft?s Hyper-V server virtualization hypervisor was also benchmarked. Intel?s VMDq and Microsoft?s VMQ allowed guest operating systems to achieve these performance levels. Ten iSCSI targets were routed to ten guest instances over virtual network links.
