^ Sunday morning coming down: Lynn spotted this sad little scene on 4th street in San Francisco as we made our way to the first of several conferences this week
- @MissExpatria wow, you auditioned? for what role? phenomenal show. in reply to MissExpatria #
- @pamt456 re. Wicked, you should read the book(s). Very meaty. in reply to pamt456 #
- right… time to face the day. White noise machine not quite as effective as hoped in the snore battle. #
- live stream of the OHAC summit at http://bit.ly/AFkfa
(not much happening yet) # - getting ready to start #ohac #
- here’s what we’re doing today: http://bit.ly/9FiUR #
- Alan McClellan http://blogs.sun.com/docexchange/ will be handling my twitter stream today – I’m operating a camera (or two) #
- #ohac keen on getting started with the OpenHA Cluster summit. #
- #ohac Dr. David Cheriton of Stanford is kicking things off with presentation titled “The Network is the Cluster.” #
- #ohac If you are following the video ustream, note we are trying to fix the buzz in the audio. #
- #ohac buzz fixed. xlr needed grounding #
- #ohac Think of the network as a backplane for many loosely coupled systems. #
- #ohac Network congestion hidden in the enterprise by “over provisioning.” Typically less than 10% utilization. #
- #ohac But over provisioning not really a viable solution for cluster network. One node can demand huge bandwidth need. #
- #ohac The network in the cluster actually assumes resource control similar to an OS. The network is the operating system. #
- #ohac Modern network switch is essentially a fault tolerant computer. Dual fans/power supplies. #
- #ohac Maybe expand the role / use of this switch to handle this network OS role? #
- #ohac Many OS management functions could reside on the switch. Scheduling, DHCP, et al. #
- #ohac Huge potential for switch extensibility…but this is a conceptual shift away from the notion of a “transparent” network switch. #
- @MissExpatria hello, little girl in reply to MissExpatria #
- @MissExpatria could totally see you in that role in reply to MissExpatria #
- @glynnfoster only for the elect. Which is a mistake in reply to glynnfoster #
- #ohac Some Q&A…. Can you imagine a user process making request of this network OS? Yes, say for routing based on available capacity. #
- #ohac Do you see DBs on the switch? No, but can envisage more integration between servers and switches when it makes sense. #
- #ohac Nice presentation. Break time. #
- #ohac Starting panel discussion – high availability today and tomorrow. #
- #ohac Downtime usually ends up in the news. Hard to quantify those [negative] costs. #
- #ohac Availability is part of our everyday lives. Users understand and expect availability, but don’t really comprehend how it is achieved. #
- #ohac Availability requirements differ for long running jobs vs. transactional work. #
- #ohac Spectrum of HA varies based on the service that is expected. What is it you want to be available and what happens if failure? #
- #ohac Customers typically do not really understand their availability requirements. Often driven by their budget. #
- #ohac IT, admins, staff needs to understand their entire infrastructure to satisfy availability needs. #
- #ohac Availability demands change based on whether the goal is service availability or data availability. #
- #ohac Lot of emphasis on simplifying the interfaces for the user so availability issues are more obvious to isolate and deal with. #
- #ohac But keep plenty of tools available under the hood for the experts who you need for that one catastrophic issue. #
- #ohac …and hire/pay experts who can get under the hood and address the catastrophic problem. #
- #ohac Providing tools to help the experts find the problem is a product responsibility. #
- #ohac Users do not usually end up with entire HA solution from single vendor….rather an aggregation of technologies. #
- #ohac In the end, successful HA demands standards, usability, interoperability, and intelligent customers. 🙂 And with that, we break. #
- #ohac Nicholas Solter is now speaking about “Project Colorado: A Minimal and Modular HA Cluster for OpenSolaris. #
- #ohac Seem to be experiencing some problems recording the Ustream feed. Should still be broadcasting. #
- #ohac Ustream feed now being recorded. Needed to save previous recording before could resume recording Nick’s session. #
- #ohac OpenHA Cluster bundles bunch of key packages. to get started. #
- #ohac Project Colorado minimizes hw requirements by combining COMSTAR, iSCSI, ZFS technologies. #
- #ohac These provide robust shared storage without requiring NAS. #
- #ohac OpenSolaris VNICs (i.e., crossbow) is used to provide cluster private interconnect (using VNICs instead of physical adapters). #
- #ohac Reduces overhead of initially setting up an HA cluster. Can share resources and simplify setup. #
- #ohac Cluster membership uses model referred to as weak membership…two-node cluster does not require a quorum device. #
- #ohac Places premium on service availability. Good for read-only apps, test cluster, demos, development. #
- #ohac Nick and Thurston demoing with laptop on OpenSolaris w/ 2 instances of VirtualBox VMs also running OSOL 2009.06 & OpenHA cluster. #
- #ohac They’re clustering the 2 VB OpenSolaris guests. Pretty neat. #
- #ohac Welcome, Glynn. #
- #ohac OHA cluster also features sw modularization: can install ha-cluster-full (all you need) or ha-cluster-minimal & extend as you like. #
- #ohac Shameless plug for the OpenSolaris Bible, which Nick co-authored. 🙂 #
- #ohac This is an open project… get involved and provide inputs on where you would like the OpenHA cluster work to go. #
- #ohac There is OpenHA talk at CommunityOne, and deep dive sessions on Tuesday at the Intercontinental Hotel. #
- #ohac Nick notes easiest way to obviate the problems of weak membership is to build 3 node cluster. #
- #ohac There is work underway to integrate MySQL replication. Will be more on this in a session this p.m. #
- #ohac getting ready to start the afternoon sessions http://bit.ly/Zu7gI #
- #ohac Next session is starting in a few minutes. Sreeram Duvur is going to discuss Glassfish Clustering for Telecommunications. #
- #ohac track 2 now streaming on http://bit.ly/Zu7gI
Tirthankar on Getting Started with OHAC # - #ohac Telco and HA are synonymous. It’s taken for granted in most of the world. #
- #ohac Need continuous service at scale. #
- #ohac Challenges of application layer are many…multiple protocols, load/data partitioning, failover, rolling upgrade, preserving state… #
- #ohac track 2 Tirthankar is explaining why you would need VNICs #
- #ohac Clustering in telcom also requires integration into fabric of existing applications. #
- #ohac track 2 Tirthankar says you should participate in OHAC for the “bragging rights” 🙂 #
- #ohac track 2 Prasad Dharmavaram is now talking about Developing Custom Application Data Services on OHAC #
- #ohac Ooops. Seem to have lost ustream broadcast. on MySQL / SunCluster session. Working issue. #
- #ohac Apologies for usteam video probs. I believe audio is still coming through, so will wait until next break & restart ustream session. #
- #ohac track 2 Prasad Dharmavaram is explaining the tools available for building applications in OHAC #
- #ohac Track 1 – going to restart ustream now. Hopefully back up after break with video for you. #
- #ohac track 2 short break till 2:20pm PT #
- #ohac Track 1 – Looks like we’re back online with video. Sorry for those technical issues. #
- #ohac Track 1 – Thorsten Frueauf and Ashutosh Tripathi are presenting OpenHA cluster with VirtualBox. #
- #ohac track 2 Marcelo Leal on OHAC and AVS to provide High Available services using NON-shared disks http://bit.ly/Zu7gI #
- #ohac Track 1 – Using OpenHA and VirtualBox together a great way to achieve low cost, easy to set up dev, training, test system. #
- #ohac Track 1 – Requires min 3GB memory, 80 GB disk; dual-core CPU useful, and net connectivity to OpenSolaris repository. #
- #ohac Track 1 – Thorsten mimics use of Solaris zones with VirtualBox guests. #
- #ohac track 2 Marcelo Leal is giving a live demo on using NON-shared disks with Virtualbox http://bit.ly/Zu7gI #
- #ohac Track 1 – Thorsten is in the midst of an OpenHA cluster / VirtualBox demo. #
- #ohac Track 1 – Ashutosh is now talking more generally about HA in virtualized environments. #
- #ohac track 2 10 minute break #
- #ohac Track 1 – Taking another break now. Next up is Steve McKinty discussing HA and business continuity. #
- #ohac Track 1 – Steve is getting going…. wants to serve as a reminder of why we care about HA and to discuss OpenHA geo edition. #
- #ohac Track 1 – HA is really about building resilience and safeguarding interests of stakeholders. #
- #ohac track 2 Jim Walker and Sekhar Lakkapragada are now live talking about Testing OpenSolaris Cloud Clusters http://bit.ly/Zu7gI #
- #ohac Track 1 – Steve refers to earlier comments by panelists… most users don’t know their HA needs. This needs to be top-down analysis. #
- #ohac Track 1-Need to understand things essential to reestablish service. These drive HA priorities. (What’s most important to look after?) #
- #ohac Track 1 – The OpenHA cluster geo edition combines Hot site + replication. Redundant clusters. #
- #ohac Track 1 – Steve is wrapping up. I think that does it for track 1 OpenHA Cluster presentations for the day. Thanks for following. #
- #ohac Shutting down track 1 ustream broadcast. #
