While catching up with e-mail this morning, I noticed that the OpenSolaris community is planning to integrate the Berkeley packet filter into opensolaris: “This case seeks to build on the Crossbow (PSARC/2006/357[7]) infrastructure and provide a new (to OpenSolaris) mechanism for capturing packets: the use of the Berkeley Packet Filter (BPF). The goal of this [...]
While preparing my presentation for the Atlanta UNIX users group this past weekend, I accidentally created a VNIC with the wrong name. Instead of removing it and recreating it, I decided to test out the “rename-link” subcommand that was introduced as part of project Clearview. The rename feature worked swimmingly, and with a single dladm [...]
I gave a talk tonight on network virtualization at the Atlanta UNIX users group. The talk focused on the OpenSolaris network virtualization project (project Crossbow), and described Crossbow and how to use it. I posted the slide deck I used on my website, so you can grab the presentation and the latest Nevada build and [...]
Project brussels from the OpenSolaris project revamped how link properties are managed, and their push to get rid of ndd and device-specific properties is now well underway! Link properties are actually pretty cool, and they can be displayed with the dladm utilities “show-linkprop” option: $ dladm show-linkprop e1000g0 LINK PROPERTY PERM VALUE DEFAULT POSSIBLE e1000g0 [...]
The long awaited IPMP rearchitecture bits just got included into the crossbow integration in OpenSolaris build 107. A new command, ipmpstat has been introduced. If you use IPMP in production, take a look at the reachitecture here. Peter’s documentation on the high level design is quality stuff. The below was taken from page 3. 3 [...]
Being able to boot a machine from SAN isn’t exactly a new concept. Instead of having local hard drives in thousands of machines, each machine logs into the fabric and boots the O/S from a LUN exported via fiber on the SAN. This requires a little bit of configuration on the Fiber HBA, but it [...]
