iSCSI before and after

I’ve blogged many 7410 performance results for the NFSv3, NFSv4, and CIFS protocols. Now it’s iSCSI’s turn. When the Sun Storage 7000 series first launched, iSCSI was provided by a user-land process: iscsitgtd. While it worked, performance wasn’t as good as the kernel-based services such as NFS. iSCSI performance was to be improved by making [...]

CIFS at 1 Gbyte/sec

I’ve recently been testing the limits of NFS performance on the Sun Storage 7410. Here I’ll test the CIFS (SMB) protocol – the file sharing protocol commonly used by Microsoft Windows, which can be served by the Sun Storage 7000 series products. I’ll push the 7410 to the limits I can find, and show screenshots [...]
