I've been playing in operating systems; mainly, I/O systems, file systems, and storage systems. You can find me in group pictures of Linux Kernel Developers Summit 2007, 2008, 2009, but who cares about what I look like?
I've been working on the target infrastructure in Linux SCSI subsystem with Mike Christie. It's known as scsi-target-utils package.
I've been working on Sheepdog project, a distributed storage system for KVM.
I founded and had maintained iSCSI Enterprise target software (IET), enables you to convert Linux machines into iSCSI storage systems. It's the most famous "iSCSI target", Google said on March 20, 2007.
I talked about the device mapper snapshot feature at Systems Administration Miniconf of linux.conf.au 2009.
If you are cool enough to know what an IOMMU is, you might enjoy DMA representations slides at 2008 Linux Storage & Filesystem Workshop.
At the 6th Linux Foundation Japan Symposium, I talked about the recent SCSI changes that I'm interested in.
Unifying the block-layer API's talk at 2007 Linux Storage & Filesystem Workshop includes things that I care about in Linux SCSI subsystem.
I'm obsessed with I/O subsystems even in virtualization environments, Xen scsifront/back drivers at Xen Summit Fall 2006.
tgt paper (and slides) appeared at Ottawa Linux Symposium 2006.
At Ottawa Linux Symposium 2005, I talked about the current state of iSCSI implementations in Linux.
My paper and slides about open-sourced iSCSI target implementations appeared at SNAPI 04, of which I was member of the program committee. You can find the longer Japanese journal version.
My paper and slides about iSCSI initiator performance issues might interest you.
I implemented a file system that can guarantee data integrity on untrusted storage systems by using cryptographic hash tree (conference and journal papers).
