We talked with Doug Cutting about whether to shoot for a TLP or a subproject under Hadoop. We decided ultimately to go the TLP route because Tashi and Hadoop are at different levels in the stack. However, we see Hadoop as one of the important applications running on Tashi virtual clusters, so the two projects are quite complementary. > * IIC Tashi is only about management, not about the underlying > storage/computing technology. Is that correct? And if so which ones do you > plan to integrate with? Yes, that's correct. We plan to integrate with the major VMMs, such as Xen, Linux KVM and VMWare. For storage, we're looking at integrating with HDFS, pVFS and later pNFS when it becomes more mature.An important goal is to provide the hooks and interfaces that allow any DFS and VMM vendor to integrate with the system. > * I can't help asking for more technical details.

Major components are cluster manager (cm), which runs on one of the cluster nodes, a node manager (nm), which runs on each of the other physical cluster nodes, a simple db on the cluster manager for configuration data, and some client utilities. We're really thinking hard about interfaces now, but don't have clear definitions yet. The kinds of things wer are thinking about are interfaces between the client and cm and cm and nm for manipulating starting, starting, and migrating vms, interfaces for some kind of event/messaging system for monitoring and reporting system state to the cm and client, interfaces between the cm/nm and storage system to allow the cm to do storage-aware scheduling of vms, interfaces to power management and system management hardware features, and possibly interfaces for federating different Tashi clusters.
